+ _AN UNINVITED GUEST_
+
+
+"Mrs. Weems, what can be delaying Dad? He promised faithfully to be home
+by three o'clock and it's nearly five now. Unless we start soon we'll
+never get to Sunset Beach tonight."
+
+Penny Parker, in blue slacks and a slightly mussed polo shirt, gazed
+disconsolately at the over-loaded automobile standing on the gravel
+driveway of the Parker home. Aided by Mrs. Weems, the family housekeeper,
+she had spent hours packing the sedan with luggage and camping equipment.
+Though the task long had been finished, Mr. Parker failed to arrive.
+
+"Your father is a very busy man," Mrs. Weems responded to the girl's
+question. "No doubt he's been held up at the office."
+
+"Then why doesn't he telephone? It's driving me crazy to wait and
+wonder."
+
+Penny's freckled little face twisted into a grimace of worry. For weeks
+she and her father, editor-owner of the _Riverview Star_, had planned a
+vacation camping trip to the nearby seashore resort, Sunset Beach. Twice
+the excursion had been postponed. Penny, who knew well her father's habit
+of changing his mind, was fearful that even now something would cause
+another vexing delay.
+
+"I'm going to call the _Star_ office this minute!" she declared, starting
+for the house.
+
+Mrs. Weems busied herself gathering up loose odds and ends that had blown
+about the yard. She was cramming waste paper into a box when Penny banged
+out the door, her eyes tragic.
+
+"I couldn't reach Dad!" she announced. "He left the office more than an
+hour ago."
+
+"Then he should have been home before this," Mrs. Weems agreed.
+
+"Something's happened. Maybe he's been run down by a car--"
+
+"Now Penny, stop such wild talk," the housekeeper interrupted sternly.
+"You know better."
+
+"But Dad was struck by an automobile last winter. What else could delay
+him?"
+
+"A dozen things," Mrs. Weems replied. "Probably a business engagement."
+
+"In that case, wouldn't he have telephoned me?"
+
+"Perhaps not. Now do stop fretting, Penny. Your father will be here
+before long."
+
+"He'd better be," Penny said darkly.
+
+Sitting down on the stone step by the door, she scuffed the toe of her
+tennis shoe back and forth in the gravel. Mrs. Weems who had cared for
+the girl ever since the death of Mrs. Parker, gazed at her sternly.
+
+"Now do stop grieving!" she chided. "That's no way to act just because
+you're impatient and disappointed."
+
+"But I've been disappointed three times now," Penny complained. "We
+planned on starting early and having a picnic lunch on the road. Dad
+promised faithfully--"
+
+A car drove up to the curb at the front of the house. Penny sprang
+hopefully to her feet. However, it was not her father who had arrived.
+Instead, her chum, Louise Sidell, alighted and came running across the
+yard.
+
+"Oh, I'm glad I'm not too late to say goodbye to you, Penny!" she cried.
+"How soon are you starting?"
+
+"I'd like to know the answer to that one myself. Dad hasn't put in an
+appearance. He was due here at three o'clock."
+
+"Why, I saw him about twenty minutes ago," Louise replied, turning to
+inspect the over-loaded sedan. "My, how did you accumulate so much
+luggage?"
+
+Penny ignored the question to ask one of her own. "Where did you see Dad,
+Lou?"
+
+"Why, riding in a car." Louise's dark eyes sparkled mischievously as she
+added: "With a beautiful brunette too."
+
+"You're joking."
+
+"I am not. Your father was riding with Mrs. Deline. She's a widow, you
+know, and has lived in Riverview less than a month."
+
+Mrs. Weems, who had overheard the conversation, came over to the steps.
+
+"Mrs. Deline, did you say?" she inquired, slightly disturbed. "I've heard
+of her."
+
+"And so have I!" declared Penny with biting emphasis. "Why, that woman
+would make the Merry Widow look like a dead number! She'd better not try
+to sink her hooks into Dad!"
+
+"Penelope!" the housekeeper reproved sternly.
+
+"Well, you know what everyone says--"
+
+"Please don't repeat idle gossip," Mrs. Weems requested. "I'm sure Mrs.
+Deline is a very fine woman."
+
+"She's the slickest serpent that ever free-wheeled into Riverview!" Penny
+said heatedly. "I saw her in action last week-end at the Country Club.
+Why, she simply went out of her way to cultivate any man who had an
+income of more than twenty-five thousand a year."
+
+"Penny, your father is a sensible man," the housekeeper reproved.
+"Unfortunately, it's a quality I'm afraid you didn't inherit."
+
+Louise, unhappy to have stirred up such a hornet's nest, said hastily:
+"Maybe it wasn't Mrs. Deline I saw. The car went by so fast."
+
+"Oh, I'm not worried. Dad can handle a bigger package of dynamite than
+Mrs. Deline. It just makes me irritated because he doesn't get here."
+
+Tossing her head, Penny crossed to the loaded automobile where she
+switched on the radio. She tuned it carelessly. After a moment a blurred
+voice blared forth:
+
+"Attention Comrades!"
+
+Penny turned quickly to glance at the dial, for she realized that she did
+not have the local station WZAM.
+
+"Attention Comrades!" the announcer commanded again. "This is the Voice
+from the Cave."
+
+There followed a strange jibberish of words which were in no language
+that Penny ever before had heard.
+
+"Mrs. Weems! Louise!" she called excitedly. "I think I've tuned in an
+outlaw short wave station! Just listen!"
+
+Louise and the housekeeper hastened over to the car. Penny tried
+desperately to tune the station in more clearly. Instead she lost it
+completely.
+
+"Did you hear what that announcer said?" she asked eagerly. "Most of it I
+couldn't understand. I'm sure it was in code!"
+
+"Code!" Mrs. Weems exclaimed in amazement.
+
+"I'm sure I didn't have one of the regular stations! It must have been a
+short wave broadcast beamed at a particular group of persons. The
+announcer began: 'Attention Comrades!'"
+
+"Can't you tune in again?" Louise demanded.
+
+Penny twisted the dial without success. She was still trying when a taxi
+cab drew up at the front door.
+
+"There's your father now!" Louise declared.
+
+"And see who's with him!" Penny added, craning her neck. "It _is_ Mrs.
+Deline."
+
+Mrs. Weems, decidedly flustered, hurriedly removed her apron. In an
+undertone she warned Penny to be polite to the unexpected visitor.
+
+Mr. Parker, a tall, lean man with hair only touched by gray, stepped from
+the taxi. The woman he assisted was attractively slender, and dressed in
+an expensive tailored suit. Her face was cold and serene, but so striking
+that it commanded instant interest. Penny's spirits sagged as she
+observed that the widow came equipped with luggage.
+
+"Now what?" she muttered.
+
+Mr. Parker escorted Mrs. Deline across the yard, introducing her first to
+Mrs. Weems and then to the girls.
+
+"Mrs. Deline is riding with us to Sunset Beach," he explained to Penny.
+"She intended to go by train but failed to get a reservation."
+
+"Coaches are so unbearable," Mrs. Deline said in an affected drawl. "It
+was so nice of Mr. Parker to invite me to share your car."
+
+"I'm afraid it may not be so pleasant for you," Penny replied. She tried
+to speak cordially but the words came in stiff little jerks. "There's not
+much room."
+
+"Nonsense!" said Mr. Parker. "Mrs. Deline will ride up front. Penny,
+you'll have to battle it out with the luggage."
+
+By the time Mrs. Deline's suitcase and hat boxes were stowed away, there
+was indeed little room left in the rear seat for a passenger. Penny's
+face was very long. For weeks she had planned on a vacation trip with her
+father, and now all her plans had been shattered.
+
+"Will you be staying long at Sunset Beach?" she asked the widow politely.
+
+"Probably a week," Mrs. Deline replied. "I've engaged a suite at the
+Crystal Inn. I'm sure I couldn't endure a camping trip. Mosquitoes--hard
+beds--cooking over a camp fire--it all seems rather difficult to me."
+
+"Oh, it will be fun to camp!"
+
+"I'm not so certain of it myself." Mr. Parker assisted the widow into the
+front seat. "Penny, why don't we ditch this camp stuff and try a hotel
+ourselves?"
+
+"No!" answered Penny fiercely.
+
+"It would be a far more sensible arrangement."
+
+"But I don't want to be sensible," Penny argued. "We've planned on this
+trip for weeks, Dad."
+
+"Oh, all right, if that's the way you feel about it," he gave in
+willingly enough. "Only I never did care much for the rough and tumble
+life myself. Are we ready to start?"
+
+"Just a minute," Penny requested. "I have to get my pocketbook from the
+house."
+
+She went indoors, her face as dark as a summer rain cloud. Mrs. Weems and
+Louise followed her in, corraling her in the kitchen.
+
+"Now Penny, just a word of advice," the housekeeper cautioned. "Mrs.
+Deline seems like a very nice woman. I trust that you'll be pleasant to
+her."
+
+"I don't see why Dad had to invite her! It's ruined everything!"
+
+"Aren't you being selfish?"
+
+"Maybe I am," said Penny. "But why should I be crammed back with the pots
+and pans and luggage while she sits up front with Dad?"
+
+"Mrs. Deline is your guest."
+
+"She's Dad's guest," Penny corrected. "Furthermore, I suspect she invited
+herself."
+
+"Whatever you think, I hope you'll keep your thoughts to yourself," Mrs.
+Weems said severely. "I'm really ashamed of you."
+
+The deep scowl disappeared from Penny's face and she laughed. Wrapping
+her arms about the housekeeper's ample waist she squeezed until it hurt.
+
+"I know I'm a spoiled brat," she admitted. "But don't worry. I'll pretend
+to like Mrs. Deline if it kills me."
+
+"That's much better, Penny. At any rate, you'll not be troubled with her
+company long. You'll reach Sunset Beach by nightfall."
+
+Penny made no reply. She turned to say goodbye to Louise.
+
+"Wish you were going along," she said wistfully. "A vacation won't seem
+fun without you."
+
+A staccato toot of the auto horn reminded Penny that her father and Mrs.
+Deline were waiting. Hurriedly she gathered up her purse.
+
+"Have a nice time," Louise said, kissing her goodbye. "And don't let Mrs.
+Deline get in your hair."
+
+Penny turned to make certain that Mrs. Weems was beyond hearing.
+
+"Don't worry about that, Lou," she whispered. "Mrs. Deline's already in
+my hair. What I'm really worried about is keeping her from building a
+nest in it!"
+
+
+
+
+ CHAPTER
+ 2
+ _STORMY WEATHER_
+
+
+For an hour the Parker car had rolled smoothly along the paved road
+enroute to Sunset Beach. In the back seat, firmly wedged between boxes
+and suitcases, Penny squirmed and suffered.
+
+"How much farther, Dad?" she inquired, interrupting an animated
+conversation he was having with Mrs. Deline.
+
+"Oh, about fifty miles," Mr. Parker tossed over his shoulder. "We can't
+make much time at thirty-five an hour."
+
+"How about lunch somewhere along the road?"
+
+"Well, should we take the time?" the publisher asked. He turned toward
+his companion. "What do you think, Mrs. Deline?"
+
+"Picnics always seemed stupid to me," she replied in a bored manner.
+"Perhaps we'll find a nice tea house along the way."
+
+"But Mrs. Weems prepared such a good lunch," Penny argued. "I thought--"
+
+"We can use the food after we make camp," Mr. Parker decided briskly. "A
+warm meal will be much better."
+
+Penny subsided into hurt silence. Since the party had left Riverview she
+felt that she had been pushed far into the background. Mrs. Deline had
+made no attempt to talk to her. On the other hand, the widow fairly
+hypnotized Mr. Parker with her dazzling smile and conversation.
+
+"Dad," Penny began, determined to get in a word, "just before you came
+home this afternoon, something queer happened."
+
+"That so?" he inquired carelessly.
+
+"Yes, I turned on the radio, and a station I'd never heard before came
+in. The announcer said: 'Attention Comrades, this is the Voice from the
+Cave.'"
+
+"Sounds like a juvenile radio serial."
+
+"Oh, but it wasn't, Dad! I'm sure it was an outlaw station. Then the
+announcer spoke very rapidly in a language I'd never heard before. It
+really sounded like code."
+
+"Sure you didn't imagine it? You know you do get ideas, Penny. Especially
+when you're on the prowl for a mystery to solve."
+
+"Aren't children quaint?" Mrs. Deline laughed.
+
+Penny's lips tightened, but by great effort of will she kept silent. A
+child indeed! She knew now that Mrs. Deline disliked her and that they
+had launched an undeclared war.
+
+"I heard the broadcast all right," she said. "For that matter, so did
+Mrs. Weems and Louise. But probably it's of no consequence."
+
+The subject was dropped. It was stuffy in the closed car and Penny
+presently rolled down a window. Immediately Mrs. Deline protested that
+the wind was blowing her hair helter-skelter. At a stern glance from her
+father, Penny closed the window again, leaving only a tiny crack for air.
+
+"All the way, please," requested Mrs. Deline.
+
+"Penny, you're being very, very difficult," Mr. Parker added.
+
+Penny rolled the window shut, but her blue eyes cast off little sparks of
+fire. As a rule, she was a very pleasant person, not in the least
+spoiled. In Riverview where she had lived for fifteen happy, eventful
+years, her friends were beyond count. Penny liked people and nearly
+everyone liked her. But for some reason, she and Mrs. Deline had taken an
+instant dislike to each other.
+
+"Maybe I'm jealous," Penny thought ruefully. "I shouldn't be, but Dad's
+all I have."
+
+Between Mr. Parker and his daughter there existed a deep bond of
+affection. Penny's mother was dead and the noted publisher had devoted
+himself to filling the great void in the girl's life. He had given her
+companionship and taught her to think straight. Knowing that she was
+dependable, he allowed her more freedom than most girls her age were
+permitted.
+
+Penny adored her father and seemingly had inherited his love of newspaper
+work. Upon various occasions she had helped him at the _Riverview Star_,
+writing and obtaining some of the paper's most spectacular front page
+stories. Only the past winter, following her father's severe illness, she
+had acted as editor of the _Star_, managing the paper entirely herself.
+
+"And now Dad and Mrs. Deline treat me as if I were a child!" she
+reflected resentfully.
+
+Though very much upset, Penny kept her thoughts to herself. Curling up
+with her head on a pile of blankets, she pretended to sleep.
+
+The car went over a hard bump. Penny bounced and opened her eyes. She was
+surprised to see that it had grown quite dark. The automobile was moving
+in a wide curve between long rows of pine trees.
+
+"What time is it?" she asked, pressing her face to the window.
+
+"Not so late," replied her father. "We're running into a rain storm. Just
+our luck."
+
+Dark clouds had entirely blotted out the late afternoon sun. Even as Mr.
+Parker spoke, several big raindrops splashed against the windshield.
+
+Soon the rain came down in such a thick sheet that the road ahead was
+obscured. Stopping suddenly for a crossroads traffic light, the car went
+into a slight skid. Mrs. Deline screamed in terror, and clutched Mr.
+Parker's arm.
+
+"Oh, can't we stop somewhere?" she pleaded. "I'm so afraid we'll have an
+accident."
+
+"Yes, we'll stop," Mr. Parker agreed. "The storm is certainly getting
+worse."
+
+A short distance ahead the party glimpsed a group of buildings. One was a
+filling station and beside it stood a small three-story hotel and tea
+room.
+
+"Doesn't look too bad," Mr. Parker commented, pulling up close to the
+door. "We'll have dinner and by that time the storm may be over."
+
+While Penny and Mrs. Deline went into the tea room, the publisher took
+the car next door to the filling station to have the tank refueled. He
+rejoined them soon, shaking the raindrops from his coat.
+
+"It's coming down harder than ever," he reported. "And we still have a
+long drive ahead of us."
+
+"Do you think we'll reach our camp site tonight, Dad?" Penny inquired
+anxiously.
+
+"We'll be lucky to get to Sunset Beach. As for making camp, that's out of
+the question."
+
+"Maybe it will stop raining soon," Penny ventured hopefully.
+
+Mr. Parker ordered dinner for the party and an hour was consumed in
+dining. The rain, however, showed no signs of slackening.
+
+"We could go on--" Mr. Parker said thoughtfully. "Of course, the roads
+are slippery."
+
+"Oh, please let's not venture out in this," Mrs. Deline pleaded before
+Penny could speak. "I know I am being silly, but I'm so afraid of an
+accident. Once I was in a car that overturned and I've never forgotten
+it."
+
+"There's no great hurry," Mr. Parker replied. "If we can't reach Sunset
+Beach tonight, I suppose we could stay here."
+
+Mrs. Deline did not comment upon the suggestion, but from the way she
+smiled, Penny was sure that the idea appealed to her. Taking her father
+aside, the girl urged him to try to drive on to Sunset Beach that night.
+
+"Our vacation is so short, Dad. Even now we'll lose almost a day in
+setting up camp."
+
+"We'll certainly push on if we can," he promised. "This storm complicates
+everything."
+
+For two hours the rain fell steadily. With the prospects anything but
+improved, Mr. Parker made inquiry as to lodging for the night. From the
+hotel keeper he learned that rooms already were at a premium.
+
+"We'll have to make up our minds soon," he reported to Penny and Mrs.
+Deline. "If we wait much longer we'll probably find ourselves sleeping in
+the lobby."
+
+"Then let's stay," the widow urged. "Please engage a room and a bath for
+me. Preferably one at the rear of the building away from the highway."
+
+"I'm afraid you'll have no choice," Mr. Parker told her regretfully.
+"We'll have to take what we can get."
+
+The publisher consulted with the hotel clerk, and returned to report that
+only two rooms remained available.
+
+"You and Penny will have to share one together," he explained. "I hope
+you won't mind."
+
+It was evident by the expression of Mrs. Deline's face that she minded a
+great deal. However, she consented to the arrangement and the luggage was
+taken upstairs. The door closed behind the bellboy. For the first time
+Penny and Mrs. Deline were left alone.
+
+"Such a cheap, dirty hotel!" the widow exclaimed petulantly. "And I do
+hate to share a room with anyone."
+
+Penny busied herself unpacking her over-night bag. Crossing to the
+window, she raised it half way.
+
+"Do put that down!" Mrs. Deline ordered. "I detest air blowing directly
+on me."
+
+Penny lowered the window.
+
+Mrs. Deline smoked a cigarette, carelessly allowing the ashes to fall on
+the bed. Getting up, she moved nervously about the room.
+
+"This place is so small it seems like a prison," she complained. "Why do
+you sit there and stare at me?"
+
+"I didn't realize I was staring," Penny apologized. "If you'll excuse me,
+I'll go to bed."
+
+Undressing quickly, she crawled beneath the covers. Mrs. Deline smoked
+still another cigarette and then began to prepare for bed. As she removed
+the jacket of her suit, Penny noticed that the woman wore a beautiful
+jade elephant pin.
+
+"Why, what an attractive ornament!" she exclaimed. "Is it a locket or
+just a pin?"
+
+"I bought it in China," the widow answered without replying to the
+question.
+
+"In China! Have you been there?"
+
+"Of course!" Mrs. Deline gave Penny an amused glance. Without removing
+the pin or offering to show it to the girl, she completed her
+preparations for bed.
+
+Just at that moment there came a light tap on the door.
+
+"Oh, Penny!" Mr. Parker called.
+
+"Yes, Dad, what is it?" Penny leaped out of bed.
+
+"I'm worried about the car keys," he called through the transom. "You
+didn't by chance see them after we left the dining room?"
+
+"Why, yes," Penny reassured him. "You left them lying on the table. I
+picked them up and forgot to tell you. They're here on the dresser. I'll
+hand them out."
+
+"No, never mind. Keep them. I was just afraid they were lost. Goodnight."
+
+Mrs. Deline glanced curiously at the key ring on the dresser. She
+remarked that she had not seen Penny pick it up.
+
+"You were talking to Dad at the time," the girl replied.
+
+Leaving the keys on the dresser, she leaped into bed again and settled
+herself for a comfortable sleep. Mrs. Deline presently turned out the
+light and took the other bed. For a time Penny was annoyed by voices from
+the hallway, then all became quiet. She slept.
+
+Much later Penny awoke. She stirred and rolled over. The rain had ceased
+and moonlight was flooding into the room. A beam fell directly across
+Mrs. Deline's bed, revealing a mass of crumpled sheets and covers.
+
+Penny stared, scarcely believing her eyes. The bed was empty.
+
+
+
+
+ CHAPTER
+ 3
+ _A JADE GREEN CHARM_
+
+
+Sitting up in bed, Penny gazed about the room. Mrs. Deline was not there
+and her clothes were gone from the chair where they had been placed
+earlier that night.
+
+"Queer," mused the girl.
+
+Jumping out of bed, she darted to the door. Though it had been carefully
+locked a few hours before, the latch now was off.
+
+Thoroughly puzzled, Penny switched on a light and glanced carefully
+about. Mrs. Deline's suitcase remained in the closet, but coat and hat
+were missing. And then Penny made an even more disturbing discovery. The
+car keys were gone from the dresser!
+
+"Why, I know I put those keys on the bureau just before I went to bed!"
+she told herself in dismay. "Now I wonder if that woman--" Ashamed of her
+thoughts, she muttered: "Guess I _am_ a suspicious brat!"
+
+Deeply mystified, she moved quickly to the window overlooking the parking
+lot and filling station. It was reassuring to see the Parker automobile
+standing where her father had left it earlier that night. But as she
+stood staring down into the dark, deserted yard, she was startled to
+observe a shadowy figure rounding a corner of the hotel.
+
+"Mrs. Deline!" she recognized the woman.
+
+Penny waited only long enough to see that the widow was walking straight
+toward the Parker sedan.
+
+"She intends to steal it!" thought the girl. "Why else would she take the
+keys?"
+
+Snatching dress and coat from a chair, Penny scrambled into them without
+taking time to remove her pajamas. She tucked up the unsightly legs of
+the garment and put on her shoes. Thus clad she ran downstairs through
+the semi-dark lobby to the side exit of the hotel.
+
+As she reached the outside door, she heard the blast of an automobile
+engine.
+
+"That's our car!" Penny thought, recognizing the sound of the running
+motor. "She'll get away before I can stop her!"
+
+The engine, evidently cold, sputtered a moment, then died.
+
+Hopeful that she might still get there in time, Penny raced across the
+parking lot. Reaching the car just as it started to move backwards, she
+jerked open the door.
+
+"Mrs. Deline!" she cried.
+
+Startled, the woman released the clutch so suddenly that the motor died
+again.
+
+"Where are you taking our car?" Penny demanded, sliding into the seat
+beside the widow.
+
+The girl's unexpected arrival seemed to completely unnerve Mrs. Deline.
+She lost composure, but only for an instant. Lighting a cigarette, she
+gazed at Penny with cold disdain.
+
+"I had intended to go for a little ride," she replied. "Any objections?"
+
+The question placed Penny on the defensive. "You shouldn't have taken the
+car without asking Dad," she said stiffly. "We barely have enough
+gasoline to reach Sunset Beach."
+
+"Oh, I had no thought of going far. I'll just drive a few miles and come
+back."
+
+"At this time of night? It must be nearly two o'clock."
+
+"I always enjoy night driving. Particularly if I am nervous and unable to
+sleep. Now run back to bed like a good child."
+
+Penny did not like the widow's tone of voice. She liked it less that Mrs.
+Deline ignored her hint that the car was not to be used. More than ever
+she was convinced that the woman had intended to steal the automobile.
+
+"I'm sorry," she said firmly. "I must ask you not to take the car without
+Dad's permission."
+
+"Well!" Mrs. Deline exclaimed indignantly. "You expect me to rap on your
+father's door at this time of night to ask if I may use the car!"
+
+"I don't see why you need to use the car at all."
+
+"Oh, you don't?" Mrs. Deline's tone was scornful. "Well, let me tell you
+this! I've already given you as much of an explanation as I intend to! I
+need the car."
+
+"I thought you said you only intended to go for a little drive--to quiet
+your nerves," Penny reminded her.
+
+"That's what I meant." Mrs. Deline tossed her cigarette through the open
+window and stepped on the car starter. "I intend to go too."
+
+Penny, equally determined, switched off the ignition.
+
+"Why, how dare you!" Mrs. Deline turned furiously upon the girl. "In all
+my life I never met such a spoiled child."
+
+"I don't mean to be rude, but I can't allow you to take the car."
+
+Mrs. Deline swung open the door on Penny's side of the seat. She reached
+as if to push the girl out of the car.
+
+Just then a man stepped from one of the hotel garages. Obviously he had
+been listening to the conversation, for he deliberately approached the
+car.
+
+"Anything wrong here?" he inquired.
+
+Penny recognized one of the night hotel clerks. She began to tell him of
+the disagreement between herself and Mrs. Deline.
+
+"This child doesn't know what she's talking about!" the widow declared
+irritably. "Mr. Parker doesn't mind if I use the car."
+
+"Then please ask him!" Penny challenged.
+
+"Why not allow me to do it for you," the hotel clerk offered. "Wait here
+and I'll call Mr. Parker. He can settle the entire matter."
+
+"No, don't bother him," Mrs. Deline decided suddenly. "I've changed my
+mind anyhow. After such a commotion I wouldn't enjoy a ride."
+
+"In any case, I'd prefer to call Mr. Parker," said the hotel man.
+
+"Do," urged Penny in deep satisfaction. "We'll wait here."
+
+"I'm going back to bed," Mrs. Deline announced, getting out of the car.
+
+She followed the hotel clerk into the building. Left in possession of the
+car, Penny reparked it and locked the doors. Then, feeling a trifle
+uneasy, she sauntered into the hotel.
+
+The lobby was deserted. Penny climbed the stairs, and in the hallway
+leading to her room, met her father and the hotel clerk. Summoned from
+bed, Mr. Parker garbed in dressing gown and slippers, looked more annoyed
+than alarmed.
+
+"Penny, what is this I hear?" he inquired. "I can't get the straight of
+the story."
+
+Penny drew a deep breath. "Well, it was this way, Dad. I awakened and
+discovered that Mrs. Deline had disappeared with the car keys."
+
+"Mrs. Deline!"
+
+"Yes, I think she meant to steal the car. But she explained that she only
+intended to borrow it for a night ride."
+
+"Anything wrong about that?"
+
+Penny regarded her father in blank amazement.
+
+"Why, Dad, would you borrow another person's car without asking?"
+
+"No, but Mrs. Deline probably didn't stop to consider the matter. No
+doubt she was too thoughtful to awaken you."
+
+"Thoughtful, my left eye! Dad, I'm sure Mrs. Deline meant to steal the
+car. Either that or she had a very important appointment--a meeting with
+someone she wasn't willing to tell us about."
+
+"Nonsense!" Mr. Parker exclaimed impatiently. "Penny, you made a serious
+mistake in refusing to allow Mrs. Deline to use the car. She is our guest
+and I'm afraid you were rude."
+
+"But Dad--"
+
+"You must apologize to her at once."
+
+Penny did not answer for a moment. She bent to tie her flapping shoe
+strings and took her time at the task. When she straightened, she said
+quietly:
+
+"All right, Dad. If you say so, I'll apologize. But I don't think I was
+wrong."
+
+"We'll not discuss it now, Penny. Suppose you turn the car keys over to
+me and go to your room."
+
+Penny gave up the keys and without another word went down the hall. Tears
+stung her eyes, but she brushed them away. She knew she had been
+unpleasant to Mrs. Deline. Nevertheless, she felt that her father had not
+been entirely just in his attitude.
+
+Entering the bedroom, she hesitated before turning on the light. Mrs.
+Deline had undressed and was in bed. She ignored the girl.
+
+"I--I guess I made a bad mistake," Penny began awkwardly. "I shouldn't
+have been so rude."
+
+Mrs. Deline rolled over in bed. Her dark eyes flashed and she made no
+effort to hide her dislike.
+
+"So you admit it?" she asked. "Well, we will forget the matter. Do not
+speak of it to me again."
+
+In silence Penny undressed and hung up her coat and dress. As she
+prepared to snap out the light, she noticed that Mrs. Deline still wore
+the jade elephant charm about her neck.
+
+"Aren't you afraid you'll break the chain?" she asked before she thought.
+"You forgot to take it off."
+
+Mrs. Deline raised herself on an elbow, fairly glaring at Penny.
+
+"Will you kindly worry about your own affairs?" she asked insolently.
+"I've had about all I can take from you in one night."
+
+"But I didn't mean anything personal."
+
+"Good night!" said Mrs. Deline with emphasis.
+
+Penny turned out the light and crept into her own bed. She felt beaten
+and hurt. It was easy to understand why Mrs. Deline disliked her, but her
+own attitude was bewildering.
+
+"I distrusted the woman the instant I met her," she reflected. "Perhaps I
+had no reason for it at first. Now I'm not so sure."
+
+Penny rolled over to face the window. Moonlight was flooding into the
+room. In the diffused light the girl could see Mrs. Deline plainly. The
+woman had propped herself up in bed and was fingering the jade green
+elephant charm which hung on its slender chain. Though Penny could not be
+certain, she thought the lid of the figure lay open and that Mrs. Deline
+quickly snapped it shut.
+
+"Good night, Mrs. Deline," she ventured, still trying to make amends.
+
+The widow did not answer. Instead she turned her back and pretended to
+sleep.
+
+
+
+
+ CHAPTER
+ 4
+ _NO CAMPING ALLOWED_
+
+
+Breakfast the next morning was a trying ordeal for Penny. Over the coffee
+cups Mr. Parker apologized to Mrs. Deline for what he termed his
+daughter's "inexcusable behavior."
+
+The widow responded graciously, quite in contrast to her attitude of the
+previous night. Without saying much, she conveyed the impression that
+Penny had been completely in the wrong, and was in fact, a spoiled child
+who must be humored.
+
+The journey on to Sunset Beach was equally unpleasant. Mr. Parker and
+Mrs. Deline seemed so absorbed in animated conversation, that they
+scarcely spoke or noticed Penny. Wedged between the luggage and the
+camping equipment, she indulged in self pity.
+
+"At least we'll get rid of Mrs. Deline when we reach Sunset Beach," she
+cheered herself.
+
+Presently the car rounded a wide curve in the road, and Penny caught her
+first glimpse of the seashore. Big waves were rolling in, washing an
+endless stretch of white sand.
+
+"Oh, isn't it beautiful!" she exclaimed, brightening. "I wish we were
+camping right on the beach instead of in the State Forest."
+
+"I fear the authorities wouldn't permit that," Mr. Parker laughed. "By
+the way, Penny, is your heart really set on this camping trip?"
+
+Penny gave him a quick look. "Yes, it is, Dad," she said briefly. "Why do
+you ask?"
+
+"Well, I was thinking that we'd be a lot more comfortable at one of the
+big hotels. We'd be right on the beach and--"
+
+"Oh, I was just talking when I said I'd like to camp on the beach," Penny
+cut in. "I'd like the State Forest much better."
+
+"Then we'll go there just as we planned," Mr. Parker said, sighing. "But
+you know I never was cut out for a rough and tumble life, Penny. I'm far
+from sure I'll make a good camper."
+
+The car rolled on along the ocean road, presently entering the little
+village of Sunset Beach. Normally a tourist center, the town now was
+practically deserted, and the Parkers had chosen it because it was within
+easy driving distance of Riverview. Nearly all of the fine hotels along
+the water front were closed. However, the Crystal Inn remained in
+operation, and it was there that Mrs. Deline had engaged a suite.
+
+The car swung into the driveway and halted in front of the hotel. An
+attendant did not come immediately so Mr. Parker himself unloaded the
+widow's luggage. Mrs. Deline gave him a dazzling smile as she bade him
+goodbye.
+
+"Oh, we'll not say goodbye just yet," Mr. Parker corrected. "Penny and I
+will camp only a short distance away. We'll run down to the beach often."
+
+"Do," urged Mrs. Deline. "I have no friends here and I'll be happy to see
+you."
+
+Mr. Parker carried the widow's luggage into the hotel. While he was
+absent, Penny moved up to the front seat. She tuned in a radio program,
+listening to it with growing impatience. Finally her father sauntered out
+of the hotel.
+
+"I nearly gave you up," Penny remarked pointedly.
+
+Mr. Parker slid behind the steering wheel and started the car. When they
+were driving along the ocean front road he said quietly:
+
+"Penny, I can't imagine what has come over you lately. You're not in the
+least like the little girl who was my pal and companion. Why have you
+been so unkind to Mrs. Deline?"
+
+"I just don't like her," Penny said flatly. "Furthermore, I distrust
+her."
+
+"You've acted very stupid and silly."
+
+"I'm sorry if you're ashamed of me," Penny replied glaring at her own
+reflection in the car mirror. "At any rate, I saved the car for you."
+
+"That accusation was ridiculous, Penny. Mrs. Deline is a wealthy woman
+who could buy herself a dozen cars in ordinary times. She merely gave in
+to a sudden whim."
+
+"Just what do you know about Mrs. Deline, Dad?"
+
+"Not a great deal," Mr. Parker admitted. "I met her at the club. She
+served as a special War correspondent in China, I believe. She has
+traveled all over the world and speaks a half dozen languages."
+
+"I never heard of her until she came to Riverview," Penny said with a
+sniff. "Nor did I ever see any of her writing in print. If you ask me,
+she's a phony."
+
+"Let's not discuss the subject further," Mr. Parker replied, losing
+patience. "When you're older, I hope you'll learn to be more gracious and
+charitable."
+
+Penny subsided into hurt silence. In all her life she could recall only a
+few occasions when her father had spoken so sternly to her. Close to
+tears, she studied the tumbling surface of the ocean with concentrated
+interest.
+
+In silence the Parkers drove through the village, stopping at a filling
+station to inquire the way to Rhett State Forest. Supplies were purchased
+at one of the stores, and by that time it was noon. At Mr. Parker's
+suggestion they stopped at a roadside inn for lunch. After that they
+drove on a half mile beyond the outskirts of Sunset Beach, past a tall
+lighthouse to the end of the pavement.
+
+"We follow a dirt road for a quarter of a mile to Bradley Knoll," Mr.
+Parker said, consulting directions he had jotted down on an envelope.
+
+"A mud road, you mean," Penny corrected, peering ahead at the narrow,
+twisting highway. "It really rained here last night."
+
+The car had no chains. Not without misgiving, Mr. Parker drove off the
+pavement onto the slippery road. The car wallowed about and at times
+skidded dangerously.
+
+"Once we reach the State park we'll have gravel roads," Penny said,
+studying a map.
+
+"_If_ we get there," Mr. Parker corrected.
+
+Barely had he spoken than the car went out of control. It took a long
+skid, turned crosswise in the road, and then the rear wheels slipped into
+a deep ditch. Opening the car door, Penny saw that the car was bogged
+down to the hub caps.
+
+Mr. Parker tried without success to pull out of the ditch. Alighting, he
+inspected the rear wheels which had spun deeper and deeper into the mud.
+
+"Not a chance to get out of here without help," he said crossly. "I'll
+have to find someone to give us a hand."
+
+Farther down the road stood a weatherbeaten farmhouse. Penny offered to
+go there to summon help, but her father insisted upon doing it himself.
+He presently returned with a farmer and a small tractor. After
+considerable difficulty the car was pulled out of the ditch.
+
+"How much do I owe you?" Mr. Parker asked the man.
+
+"Ten dollars."
+
+The amount seemed far too high for the service rendered, but Mr. Parker
+paid it without comment. His shoes were caked with mud, and so were the
+trouser legs of his suit. Only by an effort of will did he keep his
+temper under control.
+
+"Figurin' on camping in the Rhett Forest?" the farmer asked Mr. Parker.
+
+"That's right. Is it much farther?"
+
+"Only a little piece down the road. You'll strike gravel at the next
+corner. You can make it if you're careful. I don't calculate you'll have
+much fun camping in the Park though."
+
+"Why not?" asked Penny.
+
+"We've had a lot o' rain lately. The mosquitoes are bitin' something
+fierce. And the ground's mighty damp."
+
+"We have a floor to our tent," Penny said optimistically. "I think
+camping will be fun. I've always wanted to try it."
+
+The farmer started the tractor. "Then don't let me discourage you," he
+shrugged. "So long."
+
+Mr. Parker rejoined Penny in the car. "Why not call this whole thing
+off?" he suggested. "We could go to the hotel and--"
+
+"No, Dad! You promised me!"
+
+"All right, Penny, if that's the way you feel, but I know we're asking
+for punishment."
+
+By careful driving the Parkers reached the gravel road without mishap. At
+the entrance to the Rhett Park area they were stopped by a pleasant,
+middle-aged forest ranger who took down the license number of the car.
+
+"Be careful about your camp fire," he instructed. "Only last week several
+acres of timber were destroyed at Alton. We're not certain whether it was
+started by a camper or was a case of sabotage. In any case, one can't be
+too careful."
+
+"We will be," promised Mr. Parker.
+
+"Camp only in the designated sites," the ranger added. "I'll be around
+later on to see how you're getting along."
+
+Once beyond the gateway arch, Penny's sagging spirits began to revive.
+The road curled lazily between dense masses of timber fringed by artistic
+old-fashioned rail fences. Numerous signs pointed to trails that invited
+exploration.
+
+"Oh, Dad, it's really nice here!" she cried. "We'll have a wonderful
+time!"
+
+Presently the car came to an open space with picnic tables. There was a
+picturesque spot beside a rocky brook which looked just right for a camp
+site.
+
+"Let's pitch our tent here!" pleaded Penny. "You set it up while I cook
+supper."
+
+Mr. Parker unloaded the car and went to work with a will hammering the
+metal stakes of the umbrella tent. Penny busied herself sorting pots and
+pans and trying to get the gasoline stove started. Despite her best
+efforts she could not induce it to burn.
+
+In the meantime, Mr. Parker was having his own set of troubles. Three of
+the tent stakes were missing. Twice he put up the umbrella framework,
+only to have the entire structure collapse upon his head.
+
+"Penny, come here and help me!" he called. "I've had about enough of
+this!"
+
+Penny ran to her father's rescue, pulling the canvas from his head and
+shoulders. By working together they finally got the tent set up. Another
+half hour was required to put up the cots and make them.
+
+"Well, that job is done," Mr. Parker sighed, collapsing on one of the
+beds. "Such a life!"
+
+"Dad, I hate to bother you," Penny apologized, "but I can't start the
+stove. Do you mind looking at it?"
+
+Grumbling a bit, Mr. Parker went to tinker with the stove. Three-quarters
+of an hour slipped away before he succeeded in coaxing a bright flame.
+
+"All this work has given me a big appetite for supper," he announced.
+"What are we having, Penny?"
+
+"Steaks."
+
+"Sounds fine."
+
+"I forgot the salt though," Penny confessed, slapping the meat into a
+frying pan.
+
+The burner was too hot. While Penny had her back turned and was opening a
+can of beans, the steaks began to scorch. Mr. Parker tried to rescue
+them. In his haste he seized the hot skillet handle and burned his hands.
+
+"Oh, Dad, I'm so sorry!" Penny sympathized. "I guess the steaks are
+practically ruined too."
+
+"Anything else to eat?" the publisher asked, nursing his blistered hand.
+
+"Beans."
+
+"Beans!" Mr. Parker repeated with bitter emphasis. "Oh, well--dish them
+up."
+
+Penny was serving the food on tin plates when a car drove up and stopped.
+A ranger climbed out and walked over to the tent.
+
+"What's the idea, camping here?" he demanded. "Can't you read signs?"
+
+"We didn't see any sign," said Penny.
+
+The ranger pointed to one in plain sight tacked on the trunk of a tree.
+It read:
+
+"Restricted Area. No Camping Permitted."
+
+"You can't stay here," the ranger added. "You'll have to move on."
+
+Penny and her father gazed at each other in despair. After all the work
+they had done, it didn't seem as though they could break camp.
+
+"Any objections if we stay here until morning?" Mr. Parker requested.
+"We've had a pretty hard time of it getting established."
+
+The ranger looked sympathetic but unmoved.
+
+"Sorry," he said curtly. "Regulations are regulations. You may finish
+your supper if you like, then you must move on. The regular camp site is
+a quarter of a mile farther up the road."
+
+
+
+
+ CHAPTER
+ 5
+ _OVER THE AIR_
+
+
+The ranger's order so discouraged Penny and her father that they lost all
+zest for supper. Too weary for conversation, they tore up the beds,
+repacked the dishes, and pulled the tent stakes.
+
+"I've not worked so hard in years," Mr. Parker sighed. "What a mistake to
+call this a vacation!"
+
+"Perhaps it won't be so hard once we get settled," Penny said hopefully.
+"After all, we've had more than our share of bad luck."
+
+Bad luck, however, continued to follow the campers. In the gathering
+darkness, Penny and her father had trouble finding the specified camp
+ground. It was impossible to drive a car into the cleared space, so they
+were forced to carry all of the heavy luggage and equipment from the
+automobile to the camp site.
+
+By that time it was quite dark. Mr. Parker misplaced one of the tent
+stakes and could not find it without a lengthy search. As he finally
+drove it in, he hammered his thumb instead of the metal pin.
+
+"Drat it all! I've had enough of this!" he muttered irritably. "Penny,
+why not give it up--"
+
+"Oh, no, Dad!" Penny cut in quickly. "Once we get the tent up again,
+we'll be all right. Here, I'll hold the flashlight so you can see
+better."
+
+Finally the tent was successfully staked down, though Mr. Parker
+temporarily abandoned the idea of putting up the front porch. Penny set
+up the cots again and made the beds.
+
+"Hope you packed plenty of woolen blankets," Mr. Parker commented,
+shivering. "It will be cold tonight."
+
+Penny admitted that she had brought only two thin ones for each bed. "I
+didn't suppose it could get so cold on a summer night," she confessed
+ruefully.
+
+Worn by his strenuous labors, Mr. Parker climbed into the closed car to
+smoke a cigar. Penny, finding the dark tent lonesome, soon joined him
+there. She switched on the car radio, tuning in an orchestra. Presently
+it went off the air so she dialed another station. A strange jargon of
+words which could not be understood, accosted her ears.
+
+"Hold that, Penny!" exclaimed Mr. Parker.
+
+"What station can it be?" Penny speculated, peering at the luminous dial.
+"It sounds like a short wave broadcast. Must be a station off its wave
+band."
+
+She and her father listened intently to the speaker who had a resonant,
+baritone voice. Not a word of the broadcast could they understand.
+Obviously a message was being sent in code.
+
+"Dad, that sounds like the same station I heard yesterday!" Penny broke
+in. "Where can it be located?"
+
+"I'd like to know myself."
+
+Penny glanced quickly at her father. His remark, she thought, had
+definite significance. Before she could question him, the strange jargon
+ceased. The deep baritone voice concluded in plain, slightly accented
+English: "This is the Voice from the Cave, signing off until tomorrow
+night. Stand by, Comrades!"
+
+"That was no regular station," Penny declared, puzzled. "But what was
+it?"
+
+Mr. Parker reached over to turn off the panel switch. "It was an outlaw
+station," he said quietly. "The authorities have been after it for
+weeks."
+
+"How did you learn about it?"
+
+"Through various channels. Most outlaw radio stations can be traced quite
+easily by the use of modern radio-detecting devices. The enemy agent who
+operates this station is a particularly elusive fellow. Just when the
+police are sure they have him, he moves to another locality."
+
+Penny was silent a moment and then she said:
+
+"You seem to know quite a bit about this mysterious Voice, Dad."
+
+"Naturally I've been interested in the case. If the police catch the
+fellow it will make a good story for the _Star_."
+
+"Where is the station thought to be located, Dad?"
+
+"Oh, it moves nightly. The fellow obviously has a portable broadcasting
+outfit."
+
+"But isn't the general locality known?"
+
+Mr. Parker smiled as he knocked ashes from his cigar.
+
+"Authorities seem to think that it may be somewhere near here. Sunset
+Beach has countless caves, you know."
+
+"Really?" The information excited Penny. "You never told me that before,
+Dad. And I suspect that you're keeping a lot of other secrets from me
+too!"
+
+"Sunset Beach's caves are no secret. They're part of the tourist
+attraction."
+
+"All the same you never mentioned them, Dad. I thought it was odd that
+you chose this place for a vacation. Now I'm beginning to catch on."
+
+Mr. Parker pretended not to understand.
+
+"Isn't it true that you came here to do a bit of investigation work?"
+Penny pursued the subject relentlessly.
+
+"Now don't try to pin me down," Mr. Parker laughed. "Suppose we just say
+we came here for a vacation."
+
+Penny eyed her father quizzically. From the way he sidestepped her
+questions she was certain that he had more than a casual interest in the
+outlaw radio station.
+
+"Dad, will you let me help you?" she pleaded eagerly.
+
+"Help me?" Mr. Parker joked. "Why, you seem to think that I'm a
+Government investigator in disguise!"
+
+"You don't deny that you came here largely because of your interest in
+that station?"
+
+"Well, I may be a tiny bit interested. But don't jump to conclusions,
+young lady! It doesn't necessarily follow that I have set out to track
+down any enemy agent single handed." Mr. Parker brought the discussion to
+an end by opening the car door. "I'm dead tired, Penny. If you'll excuse
+me, I'll turn in."
+
+After her father had gone to the tent, Penny remained for a while in the
+car. Soberly she stared at the stars and thought over what she had
+learned.
+
+"I don't care what Dad says," she reflected, "he came here to find that
+radio station! But maybe, just maybe, I'll beat him to it!"
+
+
+
+
+ CHAPTER
+ 6
+ _BREAKFAST BLUES_
+
+
+Penny awoke next morning to find the tent cold and damp. She rolled over
+on the hard cot and moaned with pain. Every muscle in her battered body
+felt as if it had been twisted into a knot.
+
+Swinging her feet to the canvas floor, she pulled away the curtain to
+peer at her father's cot. It was empty.
+
+"Guess I've overslept," she thought. "Hope Dad's started breakfast."
+
+Penny dressed quickly, cringing as she pulled on damp shirt and shorts.
+Dew lay heavy upon the tent and the grass outside was saturated. She
+walked gingerly as she picked her way toward the parked car.
+
+Mr. Parker had set up a portable table nearby and was tinkering with the
+gasoline stove. He was unshaven and looked very much out of sorts.
+
+"Hi, Dad!" Penny greeted him with as much cheer as she could muster.
+"What are we having for breakfast?"
+
+"Nothing, so far as I can see! This stove is on strike again. I've tried
+for half an hour to get it started."
+
+Penny climbed into the car to use the mirror. The sight of her face
+horrified her. One cheek was blotched with ugly red mosquito bites, there
+were dark circles under her eyes, and her hair hung in strings.
+
+"If anyone ever gets me on another camping trip I'll be surprised!" Mr.
+Parker exclaimed. He slammed the stove down on the table. "I'm through
+monkeying with this contrary beast!"
+
+"Oh, Dad, such a temper," Penny chided, giggling despite her own
+discouragement.
+
+"Suppose you suggest how we're to eat."
+
+"Well, there's cold breakfast food with canned milk." Penny burrowed deep
+in a box of supplies stored in the car. "Two soft bananas. No coffee, I'm
+afraid."
+
+"Wonderful!" Mr. Parker said grimly. "Well, bring on the bird food."
+
+Penny set the table and dished up the dry breakfast cereal.
+
+"At least we have beautiful scenery," she remarked as she sat down to the
+dismal repast with her father. "Just look at those grand old trees."
+
+"The place is all right. It's camping that has me tied in a knot. Now at
+the Crystal Inn we could be comfortable--right on the beach too."
+
+"No," Penny said, though not very firmly. "We'll like it here after we
+get adjusted."
+
+"Need any supplies today?" Mr. Parker asked abruptly.
+
+"Yes, we'll have to have fresh meat and milk. I forgot salt too and
+bread."
+
+"I'll drive down to Sunset Beach and get the things. May as well take the
+stove along too and try to have it repaired."
+
+"That might be a good idea," Penny admitted, though with reluctance.
+"Don't be gone long, will you? I thought we might explore some of the
+trails."
+
+"Oh, there's plenty of time for that."
+
+Mr. Parker was noticeably cheerful as he stowed the portable stove in the
+car and drove away. Not without misgiving Penny watched him go. She
+remained somewhat troubled as she washed the breakfast dishes at the
+brook and struggled with the beds. The camping trip hadn't worked out as
+she had hoped and expected. So far it had been all work and no fun.
+
+"Dad was up to something when he skipped out of here so fast," she mused.
+"Wonder why he doesn't come back?"
+
+The sun rose high above the trees, drying the grass and tent. Penny went
+for a short hike in the woods. She returned to find that her father still
+had not returned.
+
+Just then a car rattled up the twisting road. Recognizing the same ranger
+who had caused so much trouble the previous night, Penny prepared herself
+for further blows. However, the government man was all smiles as he
+pulled up not far from the umbrella tent.
+
+"Just dropped by to see if you're getting along all right," he greeted
+her in a friendly way. "Everything Okay?"
+
+"I wouldn't venture such a rash statement as that," Penny answered, her
+face downcast.
+
+Because the ranger, whose name was Bill Atkins, seemed to have a genuine
+interest, she found herself telling him all about her troubles.
+
+"Why, you've not had a decent meal since you came here!" he exclaimed,
+climbing out of the car. "Maybe I can help you."
+
+"Can you wave a magic wand and produce hot food?"
+
+"We'll see," laughed the ranger. "Gasoline stoves are more bother than
+they're worth in my opinion."
+
+As Penny watched in amazed admiration he built a good fire which soon
+made a bed of glowing cherry red coals.
+
+"How about a nice pan of fish fried to a crisp brown?" the ranger tempted
+her. "I caught a string of them this morning. Beauties!"
+
+From the car he brought a basket of fat trout, already dressed and ready
+for cooking. Without asking Penny for anything, he wrapped them in corn
+meal, salted each fish and let it sizzle in hot butter.
+
+"Do you always travel with your car equipped like a kitchen cabinet?"
+Penny joked. Crouching beside the fire, she barely could take her eyes
+from the food.
+
+"Not always," the ranger laughed. "I've been on an overnight trip.
+Usually have the fixings of a meal with me though."
+
+While the fish slowly sizzled, Bill put on a pot of coffee and fried
+potatoes. He accomplished everything with such ease that Penny could only
+watch dumbfounded.
+
+"Guess you and your father considered me an old crab last night," he
+remarked. "Sometimes we hate to enforce the rules, but we have to treat
+everyone alike. If we allowed folks to camp wherever they pleased the
+danger of forest fire would be greatly increased."
+
+"You're right, of course. Have you had any fires this season?"
+
+"Not here." Deftly the ranger dished up the potatoes and crisply browned
+fish. "Plenty of them farther South. Not all caused by carelessness of
+campers either."
+
+Penny was quick to seize upon the remark. "Sabotage?" she questioned.
+
+"That's what we think," the ranger nodded. He poured two cups of
+steaming, black coffee. "Fact is, enemy agents have made quite a few
+attempts to set fire to our forests. Nearly always they're caught, but
+that doesn't mean we dare let up our vigilance."
+
+Penny ate every morsel of the food, praising the ranger highly for his
+cooking ability.
+
+"I wish Dad could have had some of this fish," she added. "He went down
+to Sunset Beach for supplies and for some reason hasn't returned."
+
+"I'll have to be on the road myself," the ranger declared, getting up
+from the ground. "I'm due in town at twelve o'clock and it's nearly that
+now."
+
+"You're driving to Sunset Beach?"
+
+"Yes, want to ride along?"
+
+Penny debated briefly. "Wait until I get my coat," she requested. "It's
+lonesome here alone. Anyway, I want to learn what's keeping Dad."
+
+The park road had dried considerably, but even so the car skidded from
+side to side until it reached the paved highway. At Sunset Beach, the
+ranger dropped Penny off at the postoffice. Rather at a loss to know what
+to do with herself, she wandered about the half-deserted streets in
+search of her father. He was not at any of the stores, nor did inquiry
+reveal his whereabouts.
+
+"Perhaps he's sunning himself on the beach," she thought.
+
+A boardwalk led over the dunes to the water front. The tide was at ebb,
+revealing a long, wide stretch of white sand strewn with shells and
+seaweed. Penny paused to gaze meditatively upon the wind-swept sea. For a
+time she watched the waves break and spill their foam on the sandy shore.
+Then she walked slowly on toward the imposing Crystal Inn.
+
+Approaching the private beach area, Penny met only a few persons, mostly
+soldiers on furlough with their girls. There were no bathers for a sharp,
+cool wind blew off the water.
+
+"Sunset Beach is nice," thought Penny, "but it's lonesome."
+
+At the Crystal Inn there was more activity. Tennis courts were in use and
+so was the swimming pool. Penny circled the well-kept grounds, not
+intending to enter the building. However, as she drew near, her attention
+was drawn to the flagstone terrace overlooking the formal garden. Though
+it was set with tables there were not many diners.
+
+Suddenly Penny stopped short, scarcely believing her eyes. At one of the
+tables near the stone railing sat her father with Mrs. Deline.
+
+
+
+
+ CHAPTER
+ 7
+ _THE BEARDED STRANGER_
+
+
+Penny's first thought upon seeing her father and Mrs. Deline was to steal
+quietly away. Then amazement and injury gave way to a feeling of
+indignation. Perhaps her father had a perfect right to lunch with Mrs.
+Deline, but it was inconsiderate of him to so completely forget his own
+daughter.
+
+"I might just as well be an orphan!" Penny sighed. "Well, we'll see!"
+
+Stiffly she marched across the lawn to the railed-in hotel veranda. Her
+father saw her coming. His look of surprise changed to one of guarded
+welcome.
+
+"Come up and have lunch with us," he invited. "The food here is quite an
+improvement on what we've been having at camp."
+
+Penny could find no outside entranceway to the terrace. To Mrs. Deline's
+horror and her father's amusement, she climbed over the stone railing.
+
+"Dad," Penny began, ignoring the widow except for a curt nod, "I was just
+about ready to get out a search warrant for you."
+
+Mr. Parker drew another chair to the table for his daughter. Her hair was
+none too well combed, she wore no stockings, and the coat did not
+entirely cover her camp costume. By contrast Mrs. Deline was perfectly
+turned out in tailored tweed suit with a smart little hat of feathers.
+Though the woman said nothing, her gaze was scornful as she appraised
+Penny.
+
+"What shall I order for you?" Mr. Parker asked, signaling a waiter.
+
+"Nothing, thank you." Penny was coldly polite. "I had a very fine lunch
+at camp, thanks to one of the rangers."
+
+"I'm sorry I didn't get back," Mr. Parker apologized. "It took a long
+while to have the stove repaired. Then I met Mrs. Deline and--"
+
+"Oh, I understand," Penny broke in. "The point is, when, if ever, are you
+coming back to camp?"
+
+"Why, right now I suppose. We've finished our luncheon."
+
+The waiter had come to the table. Mr. Parker asked for the bill, paid it,
+and arose. As he bade Mrs. Deline goodbye, he remarked that he probably
+would see her again soon.
+
+Walking to the hotel parking lot where Mr. Parker had left the car,
+neither he nor Penny had much to say. Not until they were driving through
+the village was the subject of Mrs. Deline mentioned.
+
+"I don't see why you can't be a bit nicer to her," Mr. Parker commented.
+"You scarcely spoke a word to her."
+
+"Did she say anything to me?"
+
+"Well, I don't recall."
+
+"I've treated Mrs. Deline just as well as she treats me!" Penny defended
+herself. "I'll admit I don't like her."
+
+"And you show it too."
+
+"Maybe I do, but she has no business taking so much of your time."
+
+"So that's where the shoe pinches," chuckled Mr. Parker. "My little girl
+is jealous."
+
+"The very idea!"
+
+"Mrs. Deline is brilliant--a highly educated woman and I enjoy talking to
+her," Mr. Parker said thoughtfully. "I assure you it's no more serious
+than that."
+
+Penny moved close to her father and squeezed his arm.
+
+"We've been pals for such a long while," she said wistfully. "If anything
+ever should come between us--"
+
+"Penny, you're positively morbid!" her father interrupted. "Of course
+nothing ever will come between us! Now let's talk of more cheerful
+subjects."
+
+"Such as?"
+
+"I've been thinking, Penny. You need a friend, someone to pal around
+with."
+
+"You're the only friend I need, Dad."
+
+"I mean someone your own age, Penny. Why not send for Louise Sidell? I'll
+gladly pay her train fare."
+
+"It would be fun having Lou here."
+
+"Then it's settled. We'll send a wire now." Mr. Parker turned the car
+around and drove to the local telegraph office.
+
+Before Penny could change her mind, the message was sent. Not until long
+after she and her father had returned to the park did it occur to her
+that unwittingly she might have fashioned her own undoing. Though camping
+would be far more interesting with Louise to share her experiences, it
+also would give her father added opportunity to see Mrs. Deline.
+
+"Maybe he didn't think of that angle," Penny reflected uneasily. "I'll
+keep it to myself."
+
+The following day Mr. Parker spent the entire day in camp. With the
+gasoline stove in working order, hot meals were prepared though not
+without endless effort. There were dishes to wash, beds to make, and by
+the time the tasks were done, neither Penny nor her father had any energy
+left for hiking.
+
+The second day was much easier. However, with more free time, Mr. Parker
+became increasingly restless. He missed his morning paper and was
+dissatisfied with the skimpy news reports that came in over the radio.
+Penny was not surprised when he mentioned that he would walk down to
+Sunset Beach.
+
+"Mind if I go with you?" Penny asked quickly.
+
+"Of course not," her father answered. "Why should I?"
+
+At Sunset Beach a call at the local telegraph office disclosed a message
+for Penny which had been held for lack of an address. The wire was from
+Louise and read:
+
+"ARRIVING AT SUNSET BEACH THURSDAY ON THE 12:30 PLANE. HOLD EVERYTHING."
+
+"Thursday!" Penny cried, offering the telegram to her father. "That's
+tomorrow! My, will I be glad to see Lou! This place has been like a
+morgue without her."
+
+"I imagine the town will brighten up quite a bit within the next few
+days," Mr. Parker said, a twinkle in his eye. "In fact, Louise may not be
+the only new arrival."
+
+"Is someone else coming to see us?"
+
+Mr. Parker would not answer her many questions. "Wait and see," he
+teased.
+
+Since arriving at Sunset Beach Penny had been eager to visit the
+lighthouse located on Crag Point. Noticing that the tide was low, she
+suggested to her father that they go there together.
+
+"Too long a walk," he complained. "You run along by yourself. I'll sun
+myself on the beach."
+
+Leaving her father, Penny started off alone. The sun was warm and there
+were a number of bathers splashing about in the surf. A long row of
+picturesque cottages lined the water front. They thinned out as she went
+farther up the beach, and presently there were no habitations, only
+desolate, wind-blown sand.
+
+Midway to the lighthouse, Penny met a man of early middle age who carried
+fishing rod and creel. He stared at her, hesitated, then paused to speak.
+
+"I notice you're going toward Crag Point," he remarked pleasantly. "Are
+you a stranger to this locality?"
+
+Penny admitted that she was.
+
+"Then perhaps you haven't been told that the Point is a dangerous place
+to be at high tide."
+
+"No, I hadn't heard."
+
+"The Point is very nearly covered at that time," the stranger explained.
+"There's no danger at the present moment, of course."
+
+"How long will I have here?"
+
+"Oh, several hours," the stranger replied. "There's no cause for alarm if
+you just keep watch of the tide."
+
+Penny thanked the stranger and walked on toward the lighthouse. The
+structure rose to a height of seventy-five feet above the beach and was
+reached by means of a narrow little iron stairway.
+
+No one was about the premises as Penny approached. However, as she
+started up the iron steps, a door far above her head opened. A burly,
+stout man whose face was browned by wind and sun, peered down at her.
+
+"You can't come up here!" he shouted. "No visitors are allowed!"
+
+"Oh," Penny murmured, retreating a step. "I didn't know. I only wanted to
+see the tower."
+
+"No visitors," the keeper of the light repeated. "War regulations."
+
+The rule seemed a reasonable one, but after such a long hike, Penny was
+disappointed. Walking back to the main section of the beach, she looked
+about for her father. He had disappeared.
+
+"I'll bet a cookie he's at the Crystal Inn!" she thought indignantly.
+
+But Penny could not find her father there nor at any other place along
+the water front. After an hour's search she decided that he must have
+returned to camp. Returning there, she approached the tent, noticing that
+the flap was closed, though not buttoned as she had left it.
+
+"Dad must be here," she thought.
+
+Drawing nearer she could see movement within the tent as someone brushed
+against the canvas walls.
+
+"Oh, Dad!" she called.
+
+There was no answer. But the next instant a man in rough garments and
+straw hat rushed out of the tent. Penny never before had set eyes upon
+him. She was so astonished that she gained only a fleeting impression of
+the bearded stranger. Seeing her, he thrust some object beneath his coat
+and fled into the woods.
+
+
+
+
+ CHAPTER
+ 8
+ _KEEPER OF THE LIGHT_
+
+
+Recovering from astonishment, Penny darted to the tent and jerked open
+the flap. The beds had been torn apart. Her purse, hidden beneath the
+pillow, was gone. Suitcases lay open on the canvas floor.
+
+"That man was a thief!" she thought angrily.
+
+Too late, she tried to determine which direction he had taken. She could
+hear no sound of crackling leaves or running feet.
+
+"He's lying low," she told herself. "No use chasing him. I never could
+find him among the trees."
+
+Thoroughly incensed, she went back to the disordered tent. A preliminary
+check revealed that besides the pocketbook, a pair of her father's shoes
+and a sweater had been taken.
+
+"Lucky I didn't have much money in my purse," Penny congratulated
+herself. "It was a good leather pocketbook though, and I hate to lose
+it."
+
+Going outside, she discovered other losses. The supply of groceries had
+been ransacked. Bread was gone, several oranges and a tin of cold meat.
+
+"That fellow was hungry," Penny reflected. "Probably some shiftless
+person who isn't willing to work for a living."
+
+Entering the tent again, she busied herself making the beds and repacking
+the suitcases. As she finished the task, she heard footsteps outside.
+Fearful that the thief had returned, she jerked open the canvas flap. It
+was her father who had arrived.
+
+"Oh, Dad, I'm glad you're back!" she exclaimed, rushing out to meet him.
+"We've been robbed!"
+
+"What?"
+
+Penny told him how she had frightened away the bearded stranger.
+
+"That's bad," Mr. Parker said, frowning. "I didn't suppose there was
+another camper within miles of us."
+
+"This man didn't look like a camper, Dad. He wore dirty, mussed clothing
+and a beard of at least a week's growth."
+
+"How old a fellow?"
+
+"Why, he looked young to me. And he ran like a young person."
+
+"We'll report it to the ranger," Mr. Parker said, entering the tent to
+check over his belongings. "Probably never will get any of our things
+back though."
+
+"The ranger may know who the fellow is, Dad."
+
+"That's possible," Mr. Parker admitted. "Penny, I'm glad Louise is coming
+tomorrow. I certainly don't like the idea of your remaining here in camp
+alone."
+
+"Then why don't you stay with me?" Penny countered instantly.
+
+"Well, I'm planning on being rather busy."
+
+"With Mrs. Deline."
+
+"Penny, you're impossible!"
+
+"Weren't you with her today? I looked everywhere for you."
+
+"Mrs. Deline and I did go for a little walk. No harm in that, is there?"
+
+"It all depends upon your viewpoint," Penny said loftily. "Personally, I
+consider her about as harmless as a Grade A rattler!"
+
+"Penny, enough of such talk!"
+
+"Okay," she returned grimly, "but never say I didn't warn you."
+
+"I was about to tell you," Mr. Parker resumed, "that I expect to be busy
+the next few days helping local authorities trace that outlaw radio
+station we heard on the air."
+
+"Oh!"
+
+"In fact, Army experts are being sent here to aid in the work. My days
+will be pretty well tied up."
+
+"I'm sorry, Dad," Penny said contritely. "Naturally I thought--"
+
+"I'm afraid your trouble is that you don't stop to think," Mr. Parker
+lectured. "Please, will you forget Mrs. Deline?"
+
+"I promise not to bother you about her again, Dad."
+
+"Good!" Mr. Parker awkwardly patted his daughter's hand. "I realize
+you've had an unpleasant time of it so far, Penny. But things should pick
+up after Louise arrives."
+
+"And that other surprise you hinted about?"
+
+"Oh, you'll have to wait and see," Mr. Parker smiled. "However, I promise
+you that what's coming really will prove a pleasant surprise."
+
+Though Penny kept up a running fire of questions, her father would tell
+her no more. From a few hints he dropped, she gathered that he was
+expecting a visitor within a day or so. That rather disappointed her, for
+with the exception of Louise, she could think of no one she particularly
+wanted to see at Sunset Beach.
+
+Later that day when a forest ranger stopped at camp for a few minutes,
+Mr. Parker reported the theft of food and clothing to him.
+
+"So the thief was a young man with a beard?" the ranger pondered. "Don't
+know of anyone in the area answering such a description. We'll certainly
+be on the watch for him."
+
+Penny and her father expected to hear no more from the matter. Toward
+sundown, however, the same ranger returned to camp, bringing the missing
+pocketbook. It was stripped of money but still contained a compact and
+various toilet articles.
+
+"Where did you find the purse?" Penny inquired eagerly.
+
+"On the Beech Trail not far from here."
+
+"Then it was dropped on purpose?"
+
+"Apparently it was. I followed the trail for a quarter of mile, then lost
+the fellow when he took to the brook."
+
+"Rather a smart fellow to think of that," commented Mr. Parker
+thoughtfully. "Perhaps he wasn't an ordinary snatch-thief after all."
+
+The ranger offered no comment. As he turned to go, he did assure Penny
+again that every effort would be made to capture the culprit.
+
+"If the fellow still is in the park we'll get him," he declared. "Don't
+you worry about that."
+
+With the coming of dusk a penetrating chill settled over the camp. Even
+the hot supper of steak and potatoes that Penny prepared failed to
+sufficiently warm the two tenters. They did the dishes and then, not
+wishing to go to bed, sought the enclosed car for heat.
+
+"It's starting to rain," Mr. Parker observed as a few drops splashed
+against the windshield. "Looks as if we're in for another siege of it."
+
+"And Louise is due tomorrow," Penny sighed. "Unless the weather improves
+I'd not blame her one bit if she turns right around and starts back to
+Riverview."
+
+The rain came down steadily with a promise of continuing throughout the
+night. Mr. Parker read a day-old newspaper by the light in the car,
+grumbling because the news was so old. Presently he switched on the
+radio, trying without success to tune in the outlaw station which had
+been heard previously at the same hour.
+
+"No luck," he commented. "Reception must be poor tonight, or the station
+has changed to another time. Probably it's shifted to a different
+locality too."
+
+"Dad, isn't it true that the operator of that secret station is an enemy
+agent?" Penny asked curiously.
+
+"It's a possibility."
+
+"Why not tell me all about it?"
+
+"Nothing to tell yet, Penny. Confidentially I'll admit I came here hoping
+to help State authorities find the station. So far I've accomplished
+nothing."
+
+"What clues have you gained?"
+
+"Now Penny, don't quiz me," Mr. Parker laughed. "I'll tell you everything
+as soon as I'm free to do so."
+
+"In the meantime, maybe I'll find out for myself!" Penny hinted. Abruptly
+swinging open the car door, she bolted through the rain to the tent.
+
+Breakfast the next morning was a more cheerful meal than had been
+expected. During the night the rain had ceased and a hot morning sun soon
+dried out the drenched canvas. Mr. Parker prepared coffee, eggs and
+bacon, an unbelievable example of perfect cooking.
+
+"Dad, I didn't think you had it in you!" Penny praised as she sat down on
+a camp stool beside him. "Maybe you'll develop into a real camper after
+all."
+
+"Not if I have anything to say about it." Grinning, Mr. Parker dropped
+two plump fried eggs on his daughter's plate and took the remaining four
+for himself. "This life could be worse though."
+
+"Dad, what time shall we start for the airport?"
+
+Mr. Parker poured himself a cup of coffee and then answered: "Afraid I
+won't be able to go with you, Penny."
+
+"But Dad! Louise will be expecting you."
+
+"It's not me she wants to see," Mr. Parker corrected. "I have an
+important engagement I can't break."
+
+Penny glanced quickly up. She was tempted to ask her father if he
+intended to see Mrs. Deline. Recalling that she had made her father a
+promise, she wisely withheld comment. Instead she asked if she might use
+the car.
+
+"By all means," he consented. "Just go easy on the gasoline."
+
+Breakfast over, dishes were dispatched and the camp put in order. By
+eleven o'clock Penny and her father were in Sunset Beach.
+
+"Drop me anywhere," Mr. Parker instructed vaguely.
+
+Leaving her father on a street corner, Penny drove slowly toward the
+airport a mile and a quarter away. There was little travel on the winding
+highway which curled along the beach. A government jeep whizzed past and
+two soldiers shouted and waved. Penny waved back.
+
+There was no need to hurry for Louise's plane was not yet due. Penny took
+her time and enjoyed the ocean scenery. The tide was coming in and gulls
+free-wheeled over the waves, dipping down at intervals in search of food.
+
+Gazing along the deserted beach, Penny was startled to see a familiar
+feminine figure hastening toward the lighthouse on Crag Point. The woman
+wore a white scarf that half obscured her face, yet the girl easily
+recognized her.
+
+"Mrs. Deline!" she thought, idling the car. "She's certainly going to the
+lighthouse! I wonder if that gruff old keeper will drive her away as he
+did me?"
+
+Curious to learn what would happen, the girl drew up at the side of the
+road. Mrs. Deline was too far away to observe the automobile. Intent only
+upon her own affairs, she walked swiftly along the beach until she
+reached the base of the lighthouse.
+
+"Now to see the fun!" chuckled Penny.
+
+The keeper had appeared on the platform and was gazing down upon the
+visitor. He called something to the woman that Penny could not hear. But
+to her amazement, Mrs. Deline started up the iron stairway.
+
+Penny waited expectantly. She was certain that the keeper of the light
+would order Mrs. Deline away. Instead, he greeted her with a hearty
+handshake as if they were old friends. They entered the lighthouse tower
+room together, and the heavy door closed behind them.
+
+
+
+
+ CHAPTER
+ 9
+ _A SURPRISE FROM THE SKY_
+
+
+"Well, if that isn't strange!" Penny muttered. "I wasn't permitted to set
+foot inside the lighthouse, but in goes Mrs. Deline without a single
+question asked!"
+
+Her curiosity aroused, the girl decided to wait and watch. Twenty minutes
+elapsed. During that time Mrs. Deline did not reappear. Penny grew tired
+of her vigil.
+
+"Mrs. Deline evidently intends to stay there a long while," she thought
+as she drove on. "For all I know, she and the lighthouse keeper may be
+old friends. They did greet each other as if they were acquainted."
+
+At the airport Penny parked on the crowded lot. She dropped into the
+lunch room for a sandwich and then wandered out on the cement runway. The
+noon passenger plane presently was announced through the loudspeaker
+system. A moment later Penny glimpsed the big silver twin-motor transport
+gliding down over the tree tops. As it taxied up to unload passengers,
+she held her breath. Knowing that there had been several last-minute
+cancellation of tickets, she was afraid that Louise might not be aboard.
+
+But as the door of the big transport swung back, her chum was the second
+passenger to alight. Fresh and trim in a yellow wool suit, she flung
+herself into Penny's arms.
+
+"Have a nice trip, Lou?"
+
+"Oh, heavenly! Only it didn't last long enough. We were here almost
+before I knew we'd started. I nearly lost my ticket to an Army Major
+too!"
+
+"I was afraid you might not get here," Penny laughed, picking up Louise's
+light over-night case. "What happened to the Major?"
+
+"Oh, at the last minute he changed his mind, so the company decided I
+could have my ticket back. And here I am! How's camping?"
+
+"Not much fun so far," Penny confessed truthfully. "But I can feel things
+starting to pick up."
+
+"We'll have a wonderful time together."
+
+"You just bet we will!" Penny declared with emphasis. "Had anything to
+eat?"
+
+"Oh, yes, lunch was served on the plane."
+
+"Then we may as well start for camp. I have oodles to tell you, Lou."
+
+Midway to the parking lot, Louise paused, calling attention to a Flying
+Fortress that was coming in against the wind.
+
+"Let's watch it land," she pleaded. "Did you ever see such a beautiful
+ship?"
+
+The huge Fortress came in fast for a perfect landing. Crew members began
+to tumble out through the door. One of the young men in captain's uniform
+evidently was a passenger for he carried a suitcase.
+
+"Lou!" Penny grasped her chum's arm. "That flier looks like Jerry
+Livingston!"
+
+"Oh, it couldn't be!"
+
+"All the same, I think it is!"
+
+Penny was so excited that she barely could control her voice. Jerry
+Livingston was one of her very best friends, a former reporter on the
+_Riverview Star_. In the days before he had joined the Army Air Force,
+she and Jerry had shared many an exciting adventure. However, since he
+had gone away there had been only a few letters and those brief
+communications had contained no real news.
+
+"It _is_ Jerry!" Penny cried an instant later. "Oh, Lou, this must have
+been the surprise that Dad knew about! How could he keep it from me?"
+
+Breaking away from her chum, Penny darted across the runway. As she
+called Jerry's name, the young man turned toward her. His handsome,
+wind-tanned face became a brilliant smile. A dozen long strides carried
+him to her side.
+
+"Penny!" he cried. He didn't hesitate. He just swept her into his arms
+and kissed her.
+
+"Sorry, Penny," Jerry apologized, his eyes twinkling. "Guess I shouldn't
+have done that. But when you've not seen your one and only girl for going
+on a year--"
+
+"Your which?" Penny stammered, too confused to blush.
+
+"You are my one and only, you know," Jerry grinned. "Always were for that
+matter. Even in the days when we tracked down news stories together."
+
+Louise came hurrying up. Jerry turned to greet her and the conversation
+became less personal. But from the way Louise smiled, Penny knew she had
+seen the kiss and would demand lengthy explanations later on.
+
+"Jerry!" she cried, noticing the decorations on his trim uniform.
+"They've given you the Distinguished Flying Cross! And the Purple Heart!
+You didn't write a word about that."
+
+"Nothing to write."
+
+Indignantly, the girls pried the story from Jerry. He had piloted a
+Flying Fortress in a highly successful raid over the Romanian oil fields.
+To reach its target, the Fortress had flown through flaming refineries,
+so low to the ground that fire actually had leaped up through the bomb
+bay of the plane. Swarms of enemy fighter ships had been fought off.
+Jerry's plane was one of the few to get back to its base safely.
+
+"I was luckier than some of the other fellows," Jerry said modestly.
+"That was all. Now they've sent me home to rest up for a while."
+
+"Oh, that's marvelous!" Penny said, guiding him toward the waiting car.
+"You can spend all of your spare time with us!"
+
+Jerry grinned down at her. "I'd like nothing better. But I'm not exactly
+on furlough."
+
+"I thought you just said--"
+
+"I'm doing a special mission here at Sunset Beach for the Army."
+
+"Anything you dare tell about?"
+
+Jerry helped the girls into the car, stowed the suitcases away, and then
+slid in beside Penny.
+
+"I can't tell you very much," he replied quietly. "But I can give you a
+general idea of why I'm here. There's a certain outlaw radio station that
+has been causing the government considerable annoyance. I've been sent
+here to try to trace its location."
+
+"And that's why Dad's here too!" Penny cried. "So you two schemers
+intended to join forces all along! A pity no one could let me know!"
+
+"I didn't want your father to tell you, because until the last minute I
+wasn't sure I was coming," Jerry explained. "The radio station assignment
+is only part of the reason why I'm here."
+
+"What's the other?" Penny asked as she started the car.
+
+"I'm on the lookout for an escaped German flier. The fellow escaped from
+a Canadian prison camp and was traced to this locality."
+
+"And you're supposed to be taking a rest from flying!"
+
+"This assignment will be a vacation."
+
+"I'd call it anything but one," Penny said indignantly. Her face suddenly
+became grave. "Jerry!"
+
+"Yes?"
+
+"What does that escaped prisoner look like?"
+
+"Oh, I can't describe him. I have a photograph in my brief case. Why do
+you ask?"
+
+"Maybe I've seen him."
+
+"Where?" Jerry could not hide a smile.
+
+"Why at our camp in the woods!" Excitedly Penny told of the bearded
+stranger who had robbed the Parker stores of food and clothing. Her
+description of the man was so vague that Jerry could make little of it.
+
+"I'm afraid your thief isn't the man we're after," he said kindly. "After
+I get to a hotel and open my luggage, I'll show you his picture."
+
+"And will you let me help you trail him?"
+
+"Oh, sure," Jerry answered, only half meaning it. "By the way, drive me
+to the Crystal Inn. I have a reservation there."
+
+Penny's face fell.
+
+"Anything wrong with the place?" Jerry inquired, observing her change of
+expression.
+
+Penny shook her head. "The place is all right. It's the people who stay
+there. Jerry--"
+
+"Yes?"
+
+"Are you susceptible to brunettes?"
+
+"Never noticed it."
+
+"You'll likely meet a Mrs. Deline at the hotel," Penny warned. "Don't
+have a thing to do with her."
+
+"Why should I?" Jerry was amused.
+
+"She's already made a jelly fish of Dad," Penny went on. "Jerry, stop
+grinning! This is serious."
+
+"Sorry, I didn't know I was smiling."
+
+"I need your help, Jerry. The truth is, I'm terribly worried about Dad."
+
+"If I know your father, there's no need to worry about him."
+
+"But you don't understand this Mrs. Deline," Penny said desperately.
+"She's a very clever, scheming woman. Jerry, will you promise to help me
+try to save Dad from her clutches?"
+
+Jerry managed to keep his face straight. "I'll do my best," he promised.
+
+Penny drew a deep sigh. "Oh, I'm so glad you're here," she murmured
+gratefully. "With you fighting on my side, the war's as good as won!"
+
+
+
+
+ CHAPTER
+ 10
+ _HELP FROM MR. EMORY_
+
+
+With Jerry at Sunset Beach, the vacation already promised to take on a
+rosy hue. Penny was so thrilled to be with her friends again that she
+paid scant heed to her driving. Several times, enroute to the Crystal
+Inn, Louise had to warn her to steer more carefully.
+
+"Oh, Jerry, now that you're here the fun will start!" Penny declared
+happily. "You've no idea how dull things have been without you."
+
+"And that goes double," Jerry said with emphasis. "How's your father?"
+
+"Oh, fine!" Penny laughed. "Camping has made him cross though. By the
+way, did he know you were coming?"
+
+"Yes, I sent him a wire."
+
+"I thought so! Dad's been keeping it from me. Why all the secrecy, I
+wonder?"
+
+"Well, my trip here isn't exactly a pleasure jaunt. And if I have luck,
+I'll be gone again in a few days."
+
+"I certainly hope you have no luck then," Penny said with a laugh.
+
+The car drew up at the Crystal Inn and Jerry unloaded his suitcase. He
+was taller, Penny thought, or at least more filled out. The trim uniform
+set off his broad shoulders. As he bent to pick up his luggage, a group
+of women on the hotel veranda turned to stare at him.
+
+"I'll check in and clean up a bit," Jerry said. "Then where can I meet
+you girls?"
+
+"Oh, we'll be somewhere on the beach," Penny replied carelessly. "Do
+hurry, Jerry. We have a million things to talk over."
+
+The girls parked the car not far from the hotel. As they walked along,
+scuffing their shoes in the loose sand, they saw Mrs. Deline coming
+toward them from the direction of Crag Point.
+
+"She's evidently been at the lighthouse all this time!" Penny commented
+in an undertone. "Now how did she get in there for a visit when I
+couldn't?"
+
+Mrs. Deline saw that she would meet the girls. Frowning, she glanced
+quickly toward the boardwalk as if seeking an avenue of escape. However,
+she could not avoid meeting them without appearing to do so deliberately.
+
+"How do you do," she greeted Penny coldly.
+
+Penny paused to introduce Louise. Mrs. Deline acknowledged the girl with
+an indifferent nod. Somewhat confused, Louise nervously twisted a silver
+ring she wore. It slipped from her finger and fell into the loose sand.
+
+"Oh, how awkward of me!" she exclaimed, and stooped to retrieve it.
+
+The ring buried itself deeper in the sand.
+
+"You'll lose it entirely if you're not careful!" Penny warned. "Here, let
+me help you."
+
+Getting down on their knees, the girls sifted the sand with their hands.
+Mrs. Deline seemed amused by their difficulties and did not offer to
+help.
+
+"Well, I must be getting on to the hotel," she said casually. "I took a
+long walk this afternoon and I'm tired."
+
+"To the lighthouse?" Penny commented, before she stopped to think.
+
+Mrs. Deline glanced at her sharply. "No, not to the lighthouse," she
+replied in a tone meant to put the girl in her place. "I shouldn't think
+of walking that far."
+
+"But I thought I saw you there."
+
+"You saw me?" Mrs. Deline laughed. "Well, my dear, you certainly were
+mistaken. I walked to the 12th Street bridge. No farther."
+
+Penny started to reply, then thought better of it. There was no point in
+arguing with Mrs. Deline. However, she was certain she had seen the widow
+at the lighthouse. Why the woman should deny it she could not imagine.
+
+After Mrs. Deline had gone, Penny and Louise searched in vain for the
+missing ring. They knew it could not be many inches away, yet it kept
+eluding them.
+
+"Oh, I can't afford to lose the ring!" Louise wailed.
+
+"How valuable is it?"
+
+"It's not worth much from a money standpoint. I drew it as a prize in a
+piece of wedding cake and I've always kept it as a good luck piece."
+
+"We'll find it," Penny said confidently. "That is, if the tide doesn't
+catch us first."
+
+Just as she spoke, a wave came rippling up the beach. It broke only a few
+feet away, showering the girls with spray and wetting their shoes.
+
+"If the tide flows over this spot, I never will find the ring," Louise
+cried in vexation. "Such wretched luck!"
+
+"Having trouble?" inquired a deep masculine voice.
+
+Penny and Louise raised their heads. Unnoticed by them, a stranger had
+approached. The man wore a wet bathing suit plastered with sand. He had
+on glasses and a moment elapsed before Penny recognized him as the same
+fisherman who had warned her about the tide at Crag Point.
+
+"I'm George Emory," he introduced himself. "Have you lost something?"
+
+"My ring," Louise explained.
+
+The man helped the girls search for the missing trinket. By now waves
+were creeping higher and higher on the beach. A particularly big one sent
+Penny and Louise scurrying for safety.
+
+"It's no use looking any longer for the ring," Louise gave up. "Perhaps I
+can find it after the tide turns."
+
+"By then it will be washed away," replied Mr. Emory. "Ah! What's this?"
+
+He stooped to pick a shiny object from the sand.
+
+"It's my ring!" Louise cried in delight. "Oh, thank you for finding it!"
+
+The three retreated to higher ground. As Penny and Louise were about to
+start for the hotel, Mr. Emory suggested that they might like to share a
+picnic lunch with him. Neither of the girls was hungry, but to offend the
+man after he had found Louise's ring was unthinkable. Accordingly, they
+accompanied him to one of the gaily painted wooden umbrellas along the
+beach. Beneath its shade Mr. Emory spread a paper tablecloth and produced
+ample supplies of sandwiches, fruit and lemonade.
+
+"Were you expecting to eat all this food yourself?" Penny asked in
+amazement.
+
+"No, I was hoping to find a companion who would share it," replied Mr.
+Emory. "The truth is, I'm a pretty lonely old fellow."
+
+Penny and Louise stole a quick look at the stranger. By no stretch of the
+imagination could they call him old. Judging from appearances, he was not
+yet forty years old.
+
+"My wife died a few years ago," Mr. Emory explained sadly. "Since then
+I've been like a ship without a rudder. I have plenty of money, but I
+don't get much enjoyment out of life. I go wherever it suits my fancy,
+stay until I weary of it, then move on."
+
+"Oh, I see," Penny murmured with a show of sympathy.
+
+She felt ashamed of herself that the story did not move her more deeply.
+Mr. Emory evidently was a lonely fellow, deserving of companionship. Yet
+for some reason, he failed to interest her.
+
+"Have you been at Sunset Beach long?" she inquired politely.
+
+"Oh, about a month. I know every nook and cranny along the shore."
+
+"You do?" Penny asked, and her interest revived. "Are there many caves
+near Sunset Beach?"
+
+"Plenty of them, though none very close. There are several near the
+lighthouse, back among the rocks. Crystal Cave probably is the most
+interesting. Then there are half a dozen scattered on up the shore.
+Interested in caves?"
+
+"Oh, in a general way," Penny replied carelessly.
+
+"Penny is interested in anything that suggests mystery," Louise
+volunteered with a grin.
+
+"Mystery?"
+
+"Lou's joking," Penny said quickly. She gave her chum a hard look which
+was not lost upon Mr. Emory.
+
+"Why, Penny!" Louise refused to be silenced. "Only a few minutes ago you
+were telling me about a radio broadcast said to come from a cave!"
+
+"That was just my idea," Penny said, confused. She jumped hastily to her
+feet. "We really should be going, Lou."
+
+"Oh, don't hurry away." Mr. Emory offered Louise another sandwich.
+"Speaking of mysterious radio stations, I've heard of one that is said to
+be located in a cave somewhere along these shores. Fact is, I've searched
+for it."
+
+"You have?" Penny asked, sinking back into the sand. "Any luck?"
+
+"None. But I did manage to kill quite a few afternoons. I take it that
+your father came to Sunset Beach to help the authorities search for the
+station. Right?"
+
+"Why, whatever made you think that?" Penny asked, instantly on guard. "Do
+you know my father?"
+
+"I regret I haven't the honor. I chanced to overhear a conversation at
+the hotel."
+
+"Oh," Penny murmured. She was certain that the information could have
+leaked out in only one way. Her father had told Mrs. Deline, who in turn
+had spread the news about the hotel.
+
+"I trust I'm not inquiring into secrets," Mr. Emory went on cheerfully.
+"Fact of the matter is, I might be able to help your father."
+
+"I'm sure Dad will want to talk with you."
+
+"I'll look forward to meeting your father. Think you can arrange it?"
+
+"Why, I suppose so," Penny said, though with no great enthusiasm. Again
+she experienced a queer, uneasy feeling. She did not entirely trust Mr.
+Emory.
+
+The man smiled and seemed to relax. As the girls arose to leave he tried
+once more to detain them.
+
+"See that old fellow down the beach?" he inquired, pointing to an aged
+man who was picking up objects from the sand with a sharp-pointed stick.
+
+"Yes, what about him?" Penny asked, turning to stare. "Just an ordinary
+beachcomber, isn't he?"
+
+"I'd not call Old Jake Skagway ordinary," Mr. Emory corrected. "If you're
+really interested in solving the radio station mystery, I'd advise you to
+keep watch of that rascal."
+
+"But why him?" Penny asked.
+
+"I can't explain," Mr. Emory said with finality. "It's just a tip. Take
+it or leave it."
+
+Yawning, he stretched himself full length on the sand and turned his back
+to the girls.
+
+
+
+
+ CHAPTER
+ 11
+ _A MAN OF MYSTERY_
+
+
+The following day when Penny told her father of Mr. Emory's desire to
+meet him, Mr. Parker showed little interest.
+
+"I've no time to waste getting acquainted with strangers," he said. "Why
+is the man so eager to know me?"
+
+"He thinks he may be able to help you locate that hidden radio station."
+
+Mr. Parker's annoyance visibly increased. "Penny," he said severely,
+"you've evidently been talking out of turn."
+
+"I didn't mean to let him know why you're at Sunset Beach, Dad. It sort
+of slipped out."
+
+Louise, who was washing the breakfast dishes, spoke quickly.
+
+"It was my fault," she insisted. "Penny tried to stop me, but I gave the
+information before I thought."
+
+"Well, it doesn't matter," Mr. Parker assured her kindly. "I came here
+mostly for a vacation. If I should be lucky enough to dig up a few facts
+about the radio station, well and good. If not, no harm will have been
+done."
+
+"You sent for Jerry to help you?" Penny inquired curiously.
+
+Mr. Parker shook his head. "No, I knew he was coming, but I didn't send
+for him. If I had, I'm afraid the Army wouldn't have been obliging enough
+to have filled my order."
+
+Penny helped Louise put away the camp dishes and pick up loose papers. It
+was only eight-thirty but already most of the work had been done. With
+Louise to help, camping no longer was a burden. Even Mr. Parker seemed to
+have moments of enjoying the outdoor life.
+
+"Anyone riding to Sunset Beach with me?" he inquired cheerfully. "I have
+a date with Jerry this morning."
+
+Penny and Louise both wanted to go. They washed at the brook, changed
+into becoming "town" dresses, and soon were ready.
+
+At the Crystal Inn, Jerry was not to be found. A clerk explained that the
+young man had left the hotel a half hour earlier but was expected to
+return soon.
+
+"He probably went somewhere for breakfast or a walk," Mr. Parker
+remarked, sinking into a comfortable chair. "I'll wait for him."
+
+Penny and Louise loitered in the lobby. Presently Mrs. Deline came from
+the dining room and Mr. Parker politely arose to greet her. The widow
+took a chair beside him and they began to chat in an animated way.
+
+"Let's get away from here!" Penny muttered to Louise. "I don't like the
+scenery."
+
+The girls went outside into the warm sunshine. Because the Parker
+automobile was at the curb they climbed into it and sat watching the sea.
+
+"Why do you dislike Mrs. Deline so intensely?" Louise presently asked her
+chum.
+
+"Because she's aiming to be my stepmother, that's why!"
+
+"Oh, Penny!" Louise laughed outright. "I'm sure you have a mistaken idea
+about the entire situation. Your father isn't serious in liking her."
+
+"Then he's certainly developed remarkable talents for acting," Penny
+retorted with a sniff. "I wish we'd never come to Sunset Beach."
+
+"You'd be willing to forego the mystery?"
+
+"Who cares about a radio station?" Penny asked crossly. "Dad won't tell
+me anything about the case, and probably Jerry won't either. It seems to
+be one of those affairs for the experts only."
+
+"If I know you, Penny, you'll manage to get in on the affair," Louise
+said, her eyes twinkling.
+
+Penny turned on the ignition and started the car. "I'm just not
+interested," she announced flatly. "Mrs. Deline has taken all the fun out
+of me. Want to go for a ride?"
+
+"Where?"
+
+"Oh, just up the beach."
+
+"Isn't it dangerous to drive on the sand?"
+
+"Everyone does it at low tide. The sand is hard and firm along this
+stretch of beach."
+
+Louise offered no further objection, so Penny drove slowly away from the
+hotel. The car rode on silken tires, making only a soft swishing sound as
+it rolled smoothly over the sand.
+
+"Oh, this is fun!" Louise cried in delight.
+
+"We might drive to the lighthouse," Penny proposed, steering to avoid two
+bathers who crossed in front of the car.
+
+Following the curve of the beach, the girls kept on until the sand became
+so soft that they were afraid to drive farther. The lighthouse was close
+by. Penny, curious to learn what sort of reception the keeper would
+accord her on the second visit, proposed to Louise that they call there.
+
+"If he let Mrs. Deline visit the tower why can't we?" she argued. "Come
+along, let's try to get in!"
+
+Abandoning the car on the beach, they waded through the dunes, climbed a
+fence, and ultimately reached the base of the tower. No one seemed to be
+in evidence. Penny started boldly up the iron steps. However, before she
+had gone very far, the keeper, Jim McCoy, came out on the platform.
+
+"Didn't I tell you no visitors are allowed here?" he called down angrily.
+
+"I saw a lady come here yesterday!" Penny returned.
+
+"You must have dreamed it," retorted the lighthouse keeper. "No visitors
+allowed. Don't make me tell you again!"
+
+Penny retreated, decidedly crushed.
+
+"You asked for it, kitten," Louise teased as they walked toward the car.
+"I don't blame the keeper for not wanting visitors."
+
+"Mrs. Deline was there," Penny insisted stubbornly. "Why should he deny
+it?"
+
+Half way to the car, the girls paused to pick up a few large shells lying
+in the deep sand. The task became an absorbing one. Before they realized
+it, the sun was high overhead and their faces were being burned by the
+direct rays.
+
+"Let's go," Louise urged. "The tide turned a long while ago. We should be
+returning to the hotel."
+
+"Okay," Penny agreed. She stooped to pick up another shell. As she
+straightened, she observed an old man in ragged clothing coming down the
+beach.
+
+"Lou," she said in a low tone, "there's that same man Mr. Emory was
+telling us about!"
+
+"The beachcomber?" Louise turned to stare.
+
+"Yes, and he's coming this way. Perhaps it might be worth while to watch
+him."
+
+"He's not seen us yet."
+
+Penny glanced about for a hiding place. The only one that offered was a
+huge sand dune. Pulling Louise along with her, she crouched down out of
+sight.
+
+In a moment the old beachcomber came along. He was whistling and seemed
+to have not a care in the world. His face, viewed at close range, was
+weather-beaten, his hair uncombed, and his clothing had not been washed
+in many a day.
+
+"What's so mysterious about him?" Louise whispered. "Why did Mr. Emory
+say he'd bear watching?"
+
+"Maybe he's not really a beachcomber," Penny returned, low. "He may be an
+Enemy Agent in disguise."
+
+"You have Enemy Agents on the brain!" Louise chuckled. "Likewise,
+man-snatching widows."
+
+The beachcomber passed within a few feet of the girls. He crossed the
+courtyard of the lighthouse and was seen to take a trail which led amid
+the rocks.
+
+"Lou, perhaps he's going to one of the caves!" Penny cried. "You know Mr.
+Emory said this locality is honeycombed with them."
+
+"Let him go," Louise answered indifferently. "It's lunch time and I'm
+hungry."
+
+"Your appetite will have to wait. I'm going to follow that man!"
+
+"Oh, Penny."
+
+"But this may be important."
+
+"And it may be just another of your so-called bright ideas," Louise
+retorted. "Well, lead on, and let's get it over with."
+
+The beachcomber already had disappeared amid the mass of piled-up rock
+farther back from shore. Penny had marked the locality well with her eye.
+She was able to lead Louise to the place where he had vanished.
+
+"See, there's a well-worn trail," she indicated triumphantly. "He must
+have taken it."
+
+They followed the path, and a moment later caught a fleeting glimpse of
+the beachcomber. At times the trail was so narrow that the girls barely
+could squeeze between the rocks. Wind whistled around the cliffs,
+whipping hair and blowing skirts.
+
+Unexpectedly, Penny, who was in the lead, came to the low entranceway of
+a cave.
+
+"He must have gone in there!" she declared excitedly. "Listen!"
+
+From deep within the cave the girls could hear a strange sound.
+
+"Rushing water!" Louise said in awe. "The Cave must have a waterfall or
+an underground river."
+
+"We'll soon know." Penny started into the cave only to have Louise clutch
+at her hand.
+
+"Don't be silly, Penny. We have no flashlight."
+
+"But we can't let that beachcomber get away. We want to learn what he
+does."
+
+"I can bear up without knowing."
+
+"Well, I can't," Penny announced with equal firmness.
+
+"But it may be dangerous. Let's go back to the hotel and get Jerry or
+your father."
+
+Penny hesitated, then shook her head. "You stay here if you like, Lou,"
+she replied. "I'm going inside."
+
+Before her chum could detain her, she stooped low and crawled into the
+narrow, dark tunnel.
+
+
+
+
+ CHAPTER
+ 12
+ _CAUGHT BY THE TIDE_
+
+
+Unwilling to be left behind, Louise followed her chum into the dark
+cavern. Once she and Penny were well beyond the yawning mouth of the
+cave, they could not see a foot ahead of them. Guided by the sound of
+rushing water, they groped their way along a damp wall.
+
+"This is awful!" Louise whispered nervously. "Let's turn back."
+
+Penny might have yielded to her chum's coaxing but at that moment the
+tunnel broadened out and became lighter. Directly ahead a series of steps
+led down to a lower room of the cave.
+
+"This place must be safe enough or steps wouldn't have been built here,"
+she whispered. "Don't be nervous, Lou. We may discover something
+important."
+
+Louise muttered that they were more likely to break their necks. However,
+she cautiously followed Penny down the rock-hewn steps. Half way down,
+they both paused. From below came a weird sound.
+
+"What was that?" Louise whispered.
+
+"It sounded for all the world like the note of a pipe organ!" Penny
+observed. "There it is again--a different tone this time."
+
+Noiselessly the girls moved on down the steps. Ahead of them they now
+could see a moving light which undoubtedly was a flash lantern carried by
+the beachcomber. Drawing closer, they saw the man himself. In the great
+cavern his shadow appeared grotesque and huge.
+
+"What is he doing?" Louise whispered in awe.
+
+The man was unaware that he had been followed. He stood in the center of
+the great chamber, gazing with wrapt expression at the stalagmites which
+rose in strange formations from the cave floor. The girls could hear him
+muttering to himself. At the risk of being seen they moved closer.
+
+"Music! Music!" the old man mumbled. "Talk about your pipe organs! They
+ain't in it with _this_!"
+
+He held a long stick in his hand and with it began to explore the row of
+stalagmites, striking them one by one, at first with a slow tempo and
+then faster and faster. The weird sounds echoed and reached through the
+galleries of the cavern.
+
+"Pretty!" the old man prattled. "It's the music o' Heaven. There ain't no
+music to equal it."
+
+Again the beachcomber struck the stalagmites, listening raptly while the
+sounds died slowly away.
+
+"Come on, Penny," Louise urged, tugging at her hand. "Let's get out of
+here. That old goof has lost his buttons."
+
+Decidedly crestfallen, Penny permitted herself to be pulled along the
+passage and up the steps. As the girls groped their way to the cave's
+mouth, they still could hear the weird echoing tones.
+
+"That was a good joke on you!" Louise teased. "You thought you were going
+to find a hidden radio station!"
+
+"Well, we did find a cave," Penny said defensively.
+
+"We didn't exactly discover it," Louise amended. "This must be Crystal
+Cave. Seemingly that old beachcomber regards it as his own personal
+property."
+
+"Mr. Emory certainly gave us a wrong steer. A mysterious character, my
+eye!"
+
+"You'll admit that the old fellow is interesting," Louise laughed.
+"However, I doubt he'll warrant much attention from the FBI."
+
+"All right, laugh," Penny retorted grimly. "You think my detective
+efforts are a joke anyway."
+
+"No, I don't, Penny. But I will say I doubt you'll have success tracing a
+hidden radio station. After all, it's a problem that has the State
+authorities baffled. Not to mention Uncle Sam's Army."
+
+The girls stepped from the cave out into the brilliant sunshine. Gazing
+toward the sea, they were amazed to see how high the tide had risen.
+Giant waves were washing very close to the Parker automobile left on the
+beach.
+
+"Ye fishes!" Penny exclaimed in horror. "I forgot all about the car!"
+
+"And the tide's coming in fast!"
+
+"The Point will be cut off in a few more minutes!" Penny added, recalling
+Mr. Emory's warning. "We'll have to travel, and travel fast!"
+
+Scrambling down from the rocks, the girls plunged through the dunes to
+the beach. A wind was blowing and the sea had an angry look.
+
+"If just one wave strikes the car, the wheels will sink in the sand, and
+then we'll be in it!" Penny cried.
+
+With increasing alarm she noted that sand was damp within a foot of the
+rear wheels. And as she jerked open the car door, a greedy wave nipped
+again at the rubber.
+
+"We'll soon be out of here," Louise said encouragingly.
+
+Penny stepped on the starter and to her relief the motor caught
+instantly. In great haste she turned the car around, circling away from
+the inrushing sea.
+
+"Careful!" Louise warned. "The sand is dreadfully soft this far up
+shore."
+
+Too late Penny realized the same thing. She could feel the car starting
+to bog down. The motor began to labor. Then the car stalled completely.
+
+"We're stuck!" she gasped.
+
+Both girls sprang out to look at the wheels. Their spirits sank. On one
+side, front and rear tires were bogged deep in sand.
+
+"Start the engine again!" Louise urged desperately. "I'll try to push."
+
+Penny obeyed, but her chum's puny strength made not the slightest
+impression upon the car. It could not be moved a foot. The spinning
+wheels only drove deeper and deeper into the sand.
+
+"What shall we do?" Louise asked helplessly. She turned to stare at the
+incoming sea. Each wave was breaking a little closer to the car.
+
+"This place will be under in another twenty minutes," Penny calculated.
+"Even if the car isn't washed away, the salt water will ruin it. How did
+we ever get into such a mess?"
+
+"Just by being careless. If only we weren't so far from the hotel!"
+
+"I'll run to the lighthouse," Penny decided desperately. "Maybe the
+keeper will help us."
+
+Both girls were badly frightened, not for their own safety, but because
+they feared that the car would be damaged beyond repair. Once the waves
+began to strike it, it would sink deeper and deeper into the sand. Salt
+water would corrode all of the bright chromium.
+
+"We've no time to waste!" Penny cried, darting away.
+
+The girls plunged through the sand drifts to the lighthouse. Evidently
+the keeper already had observed their plight, for he was standing on the
+upper platform peering down into the courtyard.
+
+"Our car is stuck in the sand!" Penny shouted. "Can you help us get it
+out?"
+
+"No, I can't," the keeper answered gruffly. "You should have watched the
+tide."
+
+"There's no one else to help us," Penny pleaded. "Just a little push--"
+
+"I'm forbidden to leave my post."
+
+"Then will you telephone to the Inn? Or to a garage?"
+
+"I could 'phone but it wouldn't do any good," the keeper said
+reluctantly. "Your car will be under water before a tow-car could get
+here."
+
+Exasperated by the man's unwillingness to help, Louise and Penny ran back
+to the car. Already waves were lapping against the rear wheels. The
+situation seemed hopeless.
+
+"Shall I try to push again?" Louise asked.
+
+"It wouldn't do any good. We're not strong enough." In desperation,
+Penny's gaze wandered down the deserted shore. Suddenly she saw a lone
+fisherman who was wading through the surf. She recognized him as George
+Emory.
+
+"He'll help us!" she cried confidently.
+
+The girls shouted Mr. Emory's name. Apparently he heard, for he turned
+his head quickly. Their plight, they thought, must be instantly evident,
+but Mr. Emory did not seem to comprehend. He waved his hand as if in
+friendly greeting, and then, reeling in his fish line, turned and walked
+away from them.
+
+
+
+
+ CHAPTER
+ 13
+ _A HIDDEN PACKAGE_
+
+
+"Why, Mr. Emory doesn't understand!" Penny cried, aghast. "Can't he see
+that we're stuck here with the tide rolling in?"
+
+The girls shouted again and again. If the man heard, he gave no sign.
+
+"I don't believe he wanted to help us!" Penny declared furiously.
+"Probably he's afraid he'll over-strain himself pushing!"
+
+Unwilling to give up without a last try, she sprang into the car and once
+more started the engine. It roared and labored but could not pull the
+vehicle. Sick with despair, Penny allowed the motor to idle. She slumped
+behind the steering wheel, only to straighten suddenly as she thought she
+heard her name called.
+
+Louise too heard the cry for she turned quickly toward the main road some
+yards back from the beach. A young man in uniform was running across the
+dunes toward the girls.
+
+"It's Jerry!" Penny cried jubilantly. "He'll help us!"
+
+"He will if he can," Louise corrected. "The tide's coming in so fast now.
+I doubt anyone can get us out of here now."
+
+Jerry did not waste time asking questions. Taking in the situation at a
+glance, he instructed Penny to remain at the wheel. With the motor
+racing, he and Louise pushed with all their strength. At first the rear
+wheels kept spinning in the sand. A great wave slapped the rear end of
+the car, spraying Louise from head to foot.
+
+"It's no use!" she gasped. "We can't do it."
+
+"Yes, we can!" Jerry insisted. "Try once more, Louise."
+
+Again they pushed and this time the car actually moved a few feet before
+it bogged down. Encouraged, Jerry and Louise tried harder than before.
+The wheels suddenly struck firm sand, dug in, and the car began to creep
+forward. Penny kept it moving until she was sure the footing beneath the
+tires was solid. Then she pulled up so that Jerry and Louise might leap
+aboard.
+
+"Drive as fast as you can for the hotel!" Jerry instructed crisply.
+"We'll be lucky to make it."
+
+Where an hour before the roadway along the beach had been wide and ample,
+there now was only a fringe of white sand. To avoid the incoming waves,
+Penny had to drive dangerously close to the dunes. And midway to the
+hotel, they came to a flooded stretch of beach.
+
+"We'll have to risk it," Jerry advised as Penny hesitated to drive on.
+
+The water was not deep but the sand was wet and treacherous. Choosing a
+moment between breakers, Penny braved it, and to her intense relief the
+car rolled through without sinking down.
+
+"It's clear sailing now," Jerry said as a wider strip of beach opened
+before them. "We're well beyond the Point."
+
+Mr. Emory was walking along the shore and as the car went past, he waved
+his hand in a friendly way. Penny did not bother to return the salute,
+pretending she did not see him.
+
+"I'm sure he knew we were in trouble and didn't want to help," she told
+Jerry. "The more I see of that man the less I like him."
+
+"Who is he anyhow?"
+
+"Just a vacationer. He got Lou and me all excited yesterday with his talk
+about that hidden radio station."
+
+"How do you mean?" Jerry asked with interest.
+
+Penny repeated the conversation, and mentioned how Mr. Emory had
+suggested that the old beachcomber was a mysterious character that would
+bear watching.
+
+"Not old Jake Skagway?" Jerry asked, amused.
+
+"I believe that was his name."
+
+"Jake's the only beachcomber I know hereabouts. He makes his living
+picking up things on the beach and selling them. Folks say he buries some
+of his loot in the caves."
+
+"How do you know so much about him, Jerry?"
+
+"Oh, I used to run down to Sunset Beach real often years ago. I know this
+locality like a book. Guess that's why the Army sent me here to do a
+little scouting around."
+
+Penny waited expectantly, but Jerry offered no more information as to the
+reason for his visit to Sunset Beach.
+
+"Probably Lou and I were taken in by Jake Skagway," she admitted after a
+moment. "If we hadn't followed him into the cave, we certainly wouldn't
+have involved ourselves in such difficulties."
+
+Upon reaching the Crystal Inn a few minutes later, the girls searched for
+Mr. Parker. He was nowhere to be found. After waiting for a time, they
+left the car with Jerry and hiked to the forest camp. There the early
+afternoon was devoted to camp tasks. When Mr. Parker still did not come,
+Penny proposed that they return to Sunset Beach for a plunge in the surf.
+
+"Too cold," Louise shivered.
+
+"Well, let's go down to Sunset Beach anyhow," Penny urged. "I get
+restless just sitting here in camp."
+
+"You know you want to see Jerry again," Louise teased. "'Fess up."
+
+"All right, I do want to see him," Penny admitted unabashed. "Jerry's my
+very best friend. I've not been with him in months and I suppose in a few
+days he'll be shot off to goodness-knows-where."
+
+"He's not told you very much about why he came here."
+
+"No," Penny said briefly. The subject was a sore one with her. She felt
+that both her father and Jerry were keeping secrets.
+
+The tide was still high when the girls reached the beach, but the flow
+was outward. Sprawling in the warm sand, they watched the gulls.
+
+"Wonder what became of Jerry and Dad?" Penny speculated. "They're
+probably together somewhere."
+
+"Or with Mrs. Deline," Louise suggested wickedly.
+
+She was sorry that she had spoken for Penny's face immediately became as
+black as a thundercloud.
+
+"Sorry," Louise apologized. "I was only joking."
+
+Penny continued to scowl for at that moment she glimpsed Mrs. Deline
+walking rapidly down the beach. The widow came from the direction of the
+lighthouse and was alone. To avoid the incoming waves she waded ankle
+deep through the great sand ridges along the drift fence.
+
+"That's queer," Penny muttered, sitting up.
+
+"What is?"
+
+"Why, Mrs. Deline apparently has been at the lighthouse again. What's she
+doing now?"
+
+The widow had paused. Carefully she gazed up and down the deserted shore,
+but she did not see Penny and Louise who were hidden from view by a sand
+dune. However, by raising up slightly, they could see her plainly.
+
+Mrs. Deline carried a package of considerable size under her arm.
+Seemingly satisfied that no one was at hand to observe her actions, she
+moved swiftly to one of the sand dunes near the drift fence. As the girls
+watched in amazement, she dug a deep hole and buried the package. Her
+work completed, she carefully brushed sand over the spot and obliterated
+her own footprints one by one.
+
+"What was the idea of that?" Louise asked in bewilderment.
+
+"That's what I want to know!" Penny muttered. "We'll wait until she
+leaves and then find out the contents of that package!"
+
+But Mrs. Deline did not immediately go away. Instead she sat down in the
+sand close by. The girls could not see very well but they thought she was
+writing something on the skirt of her white suit.
+
+"Why is she doing that?" Louise asked in bewilderment.
+
+"I'll bet a cookie she's writing down the location of what she hid in the
+sand dune!" Penny speculated. "That's so she can find it again!"
+
+"But why write it on her skirt? And why should she hide anything here on
+the beach?"
+
+"Because she's a spy!" Penny declared triumphantly. "I've been suspicious
+of her from the first!"
+
+"Yes, you have, darling," agreed Louise. "But would a spy necessarily
+hide a package? If Mrs. Deline had information to communicate wouldn't
+she send it to her superiors? Besides, Sunset Beach isn't even an
+important manufacturing town."
+
+"That's true. But I've heard Dad say that the Coast Guards watch this
+place closely. Because of its isolation and jagged coastline it's
+considered a likely spot for surprise night landings by the Enemy."
+
+"Only this morning you thought old Jake Skagway was a rascal," Louise
+chuckled. "You don't catch me falling for your theories this time."
+
+"Then you have no interest in that hidden package?"
+
+"Of course I have! I merely don't agree that Mrs. Deline is a spy."
+
+"Quiet!" Penny warned. "Here she comes!"
+
+Mrs. Deline had arisen from the sand and came rapidly down the beach. She
+did not see the girls until she was very close to them. Involuntarily,
+she paused, and looked somewhat disconcerted. Recovering, she spoke
+coldly.
+
+"Hello," Penny responded, her gaze on the woman's white flannel skirt. It
+bore not a single tell-tale mark.
+
+Mrs. Deline went on down the beach.
+
+"You see," Louise whispered when the woman was beyond hearing, "she
+didn't write anything on her dress."
+
+"But we saw her do it!"
+
+"We only thought we did."
+
+"Maybe she wrote it in invisible ink."
+
+"Oh, Penny, you certainly have an imagination," Louise sighed.
+
+"I suppose I imagined about the package too?"
+
+"No, she really did bury something in the sand."
+
+"Then what are we waiting for?" Penny demanded, leaping to her feet.
+"Let's dig it up, and then maybe we'll have the answer to a few of our
+questions."
+
+
+
+
+ CHAPTER
+ 14
+ _VOICE FROM THE CAVE_
+
+
+From a distance Penny and Louise had marked well the spot where Mrs.
+Deline had buried the package. But as they approached the drift fence all
+of the dunes seemed strikingly similar in appearance. They could not
+agree as to the exact mound which contained the hidden package.
+
+"It was buried in this one, I think," Penny said, starting to dig. "Mrs.
+Deline certainly did a good job of covering her tracks."
+
+"You're wasting time working on that dune," Louise insisted. "I'll get
+busy over here and turn up the package in nothing flat."
+
+Selecting a mound of sand several feet from Penny, she began to dig with
+a will. The mysterious package proved elusive. Scarcely had the girls
+started work than a few raindrops splattered down.
+
+"Oh, it's going to storm!" Louise exclaimed, turning startled eyes toward
+the dark sea.
+
+The rain came down faster and faster. Faced with a choice of abandoning
+the search or being drenched, the girls decided to make a dash for the
+hotel.
+
+As they darted up the steps at the Crystal Inn, they were surprised to
+see Mrs. Deline sitting on the veranda. A spyglass lay in her lap.
+Whether she had been watching the sea or their own antics they had no way
+of knowing.
+
+"Have you seen my father, Mrs. Deline?" Penny asked, shaking the
+raindrops from her flying hair.
+
+"Indeed, I don't keep track of his whereabouts," Mrs. Deline replied
+coldly. "By the way, did you find what you were searching for in the
+sand?"
+
+The question caught Penny off guard. She stammered a few words which only
+caused the widow to smile in a knowing, amused way.
+
+"I don't mind telling you what I buried in the sand," she resumed. "It
+may save you a little trouble. The package contained nothing but fish
+bones."
+
+"Fish bones!"
+
+"Yes, I had just visited my friend, Jim McCoy, at the lighthouse. It's
+most difficult to bury anything there because of so many rocks. He asked
+me to dispose of the scraps for him."
+
+"Oh," Penny murmured, completely deflated.
+
+"I've been watching you girls through the spyglass," Mrs. Deline went on.
+"It really was amusing."
+
+"I can imagine," Penny agreed grimly. "Oh, well, I'm glad to provide a
+little amusement for this dead place."
+
+She and Louise retreated until they were screened from the widow by a
+potted palm.
+
+"I guess she scored on you that time, Penny," Louise commented. "So we
+wasted our strength digging for garbage!"
+
+"You needn't rub it in."
+
+"But it's all so silly. Why don't we try to like Mrs. Deline, Penny?"
+
+"I'll leave that job up to you. Furthermore, how do I know she was
+telling the truth? Maybe she just handed us that story so we wouldn't go
+on digging in the dunes!"
+
+"That's so!" Louise acknowledged. "Mrs. Deline isn't the type to be doing
+gracious little jobs for anyone."
+
+"If Jim McCoy asked her to bury a package of garbage, she would have
+disposed of it long before she did," Penny reasoned. "Instead, she walked
+quite a distance down shore. Then she seemed to select a particular dune,
+as if by pre-arrangement."
+
+"You think she may have hidden something there expecting another person
+to pick it up?"
+
+"That's my theory, Lou. Oh, I wish this rain would let up."
+
+Restlessly Penny walked to a window. The rain showed signs of slackening.
+And as she watched, a taxi drew up in front of the hotel. Jerry
+Livingston leaped out.
+
+"Wait for me!" he instructed the driver. "I'll be right back."
+
+Penny and Louise managed to block Jerry's path as he came hurrying into
+the hotel.
+
+"Hello, girls," he greeted them offhanded. "Want to go for a drive into
+the country?"
+
+"We certainly do," Penny accepted for both. "What's our destination?"
+
+"Tell you on the way," Jerry answered.
+
+He disappeared into an elevator, but was back in the lobby within a few
+minutes. Taking Penny and Louise each by an elbow, he escorted them to
+the waiting cab.
+
+"In a way, this is a secret trip," he said after he had given directions
+to the driver. "Ever see a radio monitoring truck?"
+
+"Never even heard of one," Penny replied. "What is it?"
+
+"Well, we have a truck equipped so that our instruments pick up the
+direction from which any short wave broadcast is sent. It's not generally
+known that the Army's at work here, so whatever you girls see you must
+keep under your sunbonnets."
+
+The taxi sped along the country road, following a route that was
+unfamiliar to the girls. By the time it drew up several miles from Sunset
+Beach the rain had ceased.
+
+"Tumble out," Jerry said, opening the cab door. "This is the end of the
+line."
+
+He went ahead, breaking a hole in the tall hedge at one side of the road.
+Eagerly the girls followed him through the gap. In a clearing just beyond
+a clump of saplings stood what appeared to be an ordinary covered Army
+truck.
+
+An enlisted man came toward Jerry and the girls, saluting smartly.
+
+"Are you picking up any signals?" Jerry asked him.
+
+"Nothing yet, sir. The weather hasn't been very favorable."
+
+"You've had your equipment set up here two days now?"
+
+"Right, sir."
+
+"It's not likely we'll get anything today or tonight," Jerry replied.
+"Oh, well, we'll have to have patience. Sooner or later the station will
+go on the air again, and then we'll learn its location."
+
+Louise and Penny were curious to learn more about the monitoring truck.
+Jerry took them inside, introduced them to the officers, and showed them
+the radio apparatus.
+
+"Our truck is equipped with rotating antennae," he explained. "Whenever
+the unknown station starts to broadcast we'll be able to swing our loops
+toward the signals. Then we chart the signals and where the lines
+intercept, the station is located."
+
+"As you explain it, Jerry, finding any radio station is a simple matter."
+
+"It is, providing the station doesn't move in the meantime.
+Unfortunately, Mr. Voice from the Cave is an elusive fellow."
+
+"You have no idea who the man may be?"
+
+"No, he's known to FBI agents only as B4 which is a code number."
+
+"What is the purpose behind the broadcasts?" Louise inquired. "Enemy
+propaganda?"
+
+"We know that the station is enemy owned and operated," Jerry replied.
+"So far that's about all we do know, for we've been unable to break the
+code. We suspect that persons connected with the station may be aiding
+German prisoners to escape from the country."
+
+"Prisoners originally held in Canada?" Penny inquired.
+
+"Yes, they've been aided by a ring of very clever spies."
+
+Penny was silent as she thought over the information. There were many
+questions she longed to ask.
+
+"Jerry--" she began, but just then there came an interruption.
+
+In the Army truck an officer had adjusted his earphones. His attitude as
+he listened was one of tense expectancy.
+
+"Picking up any signals?" Jerry demanded.
+
+The other man nodded. "Something's coming in! Yes, it's our friend, the
+Voice. In just a minute we should know exactly where the station is
+located."
+
+Jerry and the girls remained in the truck, eagerly awaiting a report from
+the efficient men who manned the radio direction finders.
+
+"Okay, we've got it charted!" came the terse announcement a moment later.
+
+"Where's the station located?" Jerry demanded eagerly. "Let's see the
+chart."
+
+It was thrust into his hand. Jerry stared at the intercepting lines and
+then at a map of the district.
+
+"Why, the station seems to be located along the shore!" he exclaimed.
+"Apparently in one of the caves--Crystal Cave I'd judge."
+
+"That's the cave where Louise and I were!" Penny exclaimed. "But we saw
+no shortwave radio apparatus. Only crazy old Skagway who was playing a
+tune on the stalagmites."
+
+"All the same, direction finders don't lie. The broadcast came from
+Crystal Cave! But that doesn't mean the station will be there fifteen
+minutes from now."
+
+"What's to be done?" Penny asked. "Can't the Voice be caught before he
+has a chance to move his portable outfit?"
+
+"A message already has been sent to Headquarters. Army men should be on
+their way to the cave now."
+
+"Jerry, we're not far from Crystal Cave ourselves!" Penny exclaimed, her
+eyes dancing with excitement. "Can't we go there too?"
+
+"We can and will!" Jerry laughed. "But if we expect to catch our friend,
+the Voice, there's no time to lose. Come along, girls, if you're
+traveling with me."
+
+
+
+
+ CHAPTER
+ 15
+ _AFTERGLOW_
+
+
+Penny sprawled on the grass beside the dying embers of the camp fire.
+Listlessly, and with very bad aim, she hurled acorns at a brown squirrel
+chattering overhead.
+
+"You've been in a bad mood ever since we got back from Crystal Cave,"
+Louise observed, coming out of the tent. "But why take it out on that
+poor creature?"
+
+Penny raised herself on an elbow. She scowled and did not reply.
+
+Louise moved over to the fire, seating herself on a log beside her chum.
+
+"Oh, brace up," she said, slipping an arm about Penny's shoulders. "In
+all my life I've never seen you act so discouraged."
+
+"I feel lower than the worms. Nothing's gone right since we came to
+Sunset Beach."
+
+"On the contrary, I can't see that anything has gone so very wrong."
+
+"Wasn't our trip to the Crystal Cave a bust?" Penny demanded.
+
+"Well, it wasn't a success."
+
+Louise smiled wryly at the recollection. With Jerry and the Army men, she
+and Penny had spent the afternoon searching various caves along the water
+front. Not a trace had been found of the mysterious radio station which
+so plagued local authorities. The search had been a long and exhausting
+one. In the end, though the others kept on, she and Penny had been
+compelled to give up.
+
+"My feet hurt yet from scrambling over the rocks," Penny declared. "I
+suppose Jerry and those Army officers will keep searching half the
+night."
+
+"And I'll warrant they never do find the station," Louise contributed.
+"This is one mystery I wish you had never stumbled into, Penny."
+
+"I'm beginning to feel the same way, Lou. This is supposed to be a
+vacation. I'd like to see Dad and Jerry once in awhile."
+
+"So that's what's bothering you!"
+
+"Well, you know Jerry will be here only a few days at most," Penny said
+defensively. "I've barely had a chance to say 'hello' to him. Dad's
+always down at the hotel too."
+
+"What you crave seems to be male companionship."
+
+Penny tossed a stick of wood on the fire, making the sparks fly. "I could
+do with a little," she admitted. "Life is too dull here."
+
+"Dull?" Louise gazed at her chum suspiciously.
+
+"It's no use being surrounded by mystery if one can't get into the thick
+of it. So far all the adventure has by-passed us."
+
+"We might stir up a little excitement by looking for that package Mrs.
+Deline buried in the sand."
+
+"Not today," Penny said with a sigh. "Too tired. Besides, I told Jerry
+about it and he wasn't much impressed."
+
+"So that's the reason for your gloom," Louise remarked wisely. "As a
+detective you don't rate."
+
+"Something like that. Jerry met Mrs. Deline at the hotel today and he
+thought her a very charming lady."
+
+"Oh!" Louise laughed. "No wonder you're all smashed to bits!"
+
+Penny got up from the grass and began preparations for supper. She peeled
+a pan of potatoes and opened a can of corn.
+
+"We need a bucket of water from the spring," she said suggestively. "Want
+to help me carry it?"
+
+"I will," Louise agreed without enthusiasm.
+
+The trail led up a steep path to a rocky ledge from which cool spring
+water gushed out of a steel pipe. Penny drank deeply and then hung her
+tin bucket over the outlet to fill.
+
+"It's starting to get dark," she observed, noticing how shadowy the woods
+had grown. "I hope Dad returns to camp soon."
+
+"Someone's coming now," Louise remarked as her keen ears detected the
+sound of footsteps on the trail below.
+
+"Probably one of the rangers."
+
+Penny unhooked the water bucket from the pipe, and the girls started down
+the trail, carrying it between them. Emerging from among the trees, they
+glimpsed a figure below them. A woman in a dark cloak who carried a
+picnic hamper, was walking rapidly up the winding trail.
+
+Penny stopped so suddenly that she spilled water on her sandals.
+
+"Lou, that's Mrs. Deline!" she whispered.
+
+"What of it, pet? She's evidently going on a picnic."
+
+"At this time of day? And alone?"
+
+"Well, that part of it does seem a bit odd."
+
+Penny pulled her chum into the bushes beside the path. Crouching low
+beside their water bucket, they allowed the woman to pass. Looking
+neither to the right nor left, she hastened on up the trail.
+
+"She seems to be in a big hurry," Penny commented, coming out of hiding.
+"Now where do you suppose she's going?"
+
+"Probably to the cabin. One of your ranger friends told me about a rustic
+place farther up the trail. It was built especially for the enjoyment of
+the public."
+
+"But why would Mrs. Deline go there alone?"
+
+"Maybe she intends to meet someone."
+
+"Lou, that's probably what she is going to do!" Penny exclaimed. "Let's
+follow her and find out."
+
+"What about supper?"
+
+"Who cares for food?" Penny demanded. "If Dad comes home he can rustle a
+little for himself. It's more important that we follow Mrs. Deline."
+
+"Okay," Louise agreed, "only I'm in no mood to walk very far. Remember,
+we've had one wild chase today."
+
+Leaving the water bucket behind the bushes, the girls set out in pursuit
+of Mrs. Deline. Not without admiration they acknowledged that the widow
+was a better trail climber than they. Though the hamper she carried
+evidently was heavy, she fairly skimmed up the rough trail. Penny and
+Louise fell farther and farther behind.
+
+"She's heading for the cabin all right," Penny puffed. "Of course she
+intends to meet someone. Otherwise, she'd have had her picnic on the
+beach or some place closer to the hotel."
+
+A clearing opened up through a gap in the trees. Mrs. Deline paused as
+she came within view of the rustic log cabin and gazed carefully about.
+The girls saw her look at her wrist watch.
+
+"She has an appointment with someone," Penny declared.
+
+Mrs. Deline walked to the door of the cabin and tested it to make certain
+that it was unlocked. She did not go inside. Instead, she set down the
+hamper and gazed slowly about the clearing. Louise and Penny, at the
+fringe of woods, saw her start as she looked directly toward them.
+
+"She's seen us!" Louise gasped.
+
+"We'll have to go out and meet her," Penny decided instantly. "Let's
+pretend we just happened to be coming this way. But we'll stick around
+and see who she's meeting."
+
+Mrs. Deline stiffened visibly as the girls sauntered out of the woods
+toward her.
+
+"Well, this is a surprise meeting you," she said in a tone none too
+friendly. "Is your camp located near here?"
+
+"Down the trail a short distance," Penny replied, thoroughly enjoying the
+widow's discomfiture. "Having a picnic?"
+
+"Why, yes. I love the outdoors and thought I'd take a hike this
+afternoon."
+
+"It's rather late for a picnic," Penny said pointedly.
+
+"It took me longer to get here than I expected."
+
+In an effort to discourage her young annoyers, Mrs. Deline pushed open
+the door of the cabin. Before she could pick up the hamper, Penny seized
+it.
+
+"Let me," she said quickly. "My how heavy! All this food for one person?"
+
+"Certainly," Mrs. Deline answered. "Who else?"
+
+Penny set the hamper on the table. Deliberately she raised the lid. The
+basket was filled with food, enough for a dozen persons, and in the
+bottom she saw a folded wool blanket. Beneath the blanket were several
+bulky garments which she took to be men's clothing. Before she could see
+plainly, Mrs. Deline jerked the lid of the hamper into place.
+
+"Please!" she said with emphasis.
+
+"I was only trying to be helpful," Penny said, pretending to look
+injured. "Don't you want Lou and me to dust off the table and spread out
+the picnic things?"
+
+"I do not. If you'll excuse me for saying so, I came on this picnic to be
+alone. I enjoy solitude."
+
+"But it's getting dark," Penny argued. "We wouldn't think of deserting
+you. The cabin has no light."
+
+"I don't mind the dark. Anyway, I brought candles. I really prefer to be
+alone."
+
+Thus dismissed, Louise started to leave. Penny lingered, trying to think
+of some excuse. Just then, from somewhere in the woods, she heard a
+shrill whistle unlike any bird call.
+
+"What was that?" she asked alertly.
+
+"I heard nothing," said Mrs. Deline.
+
+Nevertheless, a moment later the woman sauntered to an open cabin window.
+Deliberately she turned her back to the girls, trying to block their
+view. Quickly she raised and lowered her handkerchief.
+
+The movement was deftly executed, but swift though it was, Penny saw and
+understood. Mrs. Deline had signaled to an unseen person beyond the
+fringe of trees!
+
+
+
+
+ CHAPTER
+ 16
+ _SUSPICION_
+
+
+Penny moved swiftly to the open cabin door, gazing toward the darkening
+woods. No one was visible amid the shadows. Yet she was certain that Mrs.
+Deline had signaled to someone lurking among the trees.
+
+The widow had turned from the window to unfasten the lid of the picnic
+hamper.
+
+"Since you girls are here you may as well stay and share my supper," she
+said without warmth. "There's enough food for all."
+
+Louise's chin tilted proudly. The invitation was grudgingly given, and
+she meant to decline. Penny forestalled her by saying:
+
+"How nice of you, Mrs. Deline! Of course we'll be delighted to remain."
+
+Mrs. Deline made no reply, though obviously she had not expected an
+acceptance. Irritably she laid out the picnic dishes--sandwiches, a
+salad, cake, cookies, and fruit--all carefully prepared and cooked at the
+hotel kitchen.
+
+"You certainly did bring plenty of food for one person," Penny commented,
+helping herself to a chicken sandwich. "Isn't that clothing in the bottom
+of the basket?"
+
+"Only a blanket." Mrs. Deline closed the lid firmly. "I thought I might
+need it if I should sit on the damp ground."
+
+Hungry as bears, Penny and Louise did not try to curb their healthy,
+young appetites. Mrs. Deline, on the other hand, scarcely nibbled at the
+food. Several times she arose and paced nervously to the window.
+
+"It's growing dark and I should return to the hotel," she said the
+instant the girls had finished eating. "I'll not bother to repack the
+lunch basket."
+
+"Oh, we'll help you pick up everything," Penny offered.
+
+"Please don't bother. I'll merely pay the hotel for the basket."
+
+Penny was convinced that Mrs. Deline deliberately intended to leave the
+hamper behind. Despite the deep inroads she and Louise had made,
+considerable food remained. It occurred to her that the widow hoped to
+leave what remained so that the person hiding in the woods might come to
+the cabin for it after the party had gone.
+
+"I can't be bothered with a heavy basket," Mrs. Deline said impatiently.
+"We'll just leave it on the table."
+
+"Oh, the rangers wouldn't like to have us leave food here," Penny
+protested. "It will only take a minute to clean up everything."
+
+Disregarding Mrs. Deline's order, she began to repack the remains of the
+lunch.
+
+"But I don't wish to carry the basket all the way to the hotel!"
+
+"Louise and I will help you."
+
+Tossing her head, Mrs. Deline walked out of the cabin, allowing the door
+to slam behind her. Louise and Penny finished packing the lunch and
+hastened down the trail in pursuit.
+
+"Maybe we shouldn't cross her so," Louise whispered uneasily. "I think
+she intended to meet someone here!"
+
+"I'm sure of it," agreed Penny. "We spiked her little plan. I have an
+idea who she intended to meet too!"
+
+"Who?"
+
+Penny could not answer, for by this time she and Louise were practically
+at Mrs. Deline's heels. The widow was walking as fast as she could.
+
+"You'll have to keep the basket," she told the girls irritably. "I'm sure
+I'll never carry it back to the hotel."
+
+All the way to the Parker camp Mrs. Deline ignored Penny and Louise. And
+as they bade her goodbye, she barely responded.
+
+"Can't we drive you down to the hotel in the car?" Penny offered, feeling
+slightly ashamed of her actions.
+
+"Thank you, no," the widow answered icily. "You've done quite enough for
+one day." She vanished down the darkening road.
+
+After Mrs. Deline was beyond view, the girls retraced their way to the
+spring for the water bucket. As they approached, they thought for a
+moment that they heard retreating footsteps. The realization that they
+were alone in the woods, made them a bit nervous. Hurriedly they
+recovered the bucket and carried it to camp.
+
+"Now tell me what you think, Penny!" Louise commanded when they were
+inside the tent.
+
+"Why, it's clear as crystal." Penny struck a match to the wick of the
+gasoline lantern and hung it on a hook of the tent pole. "Mrs. Deline
+went to the cabin intending to meet someone. She carried extra food, a
+blanket, and if I'm not mistaken, clothing for a man."
+
+"You thought she signaled from the window?"
+
+"I'm sure she did, Lou. She warned the person, whoever he was, not to
+approach. She hoped by leaving the basket behind to get it into his hands
+after we'd gone."
+
+"You thwarted her in that."
+
+"We did together," Penny chuckled. Her face suddenly became sober.
+"Lou--"
+
+"Yes?"
+
+"It just occurred to me! Maybe the man she intended to meet was the same
+fellow who stole food from our camp."
+
+"That's possible. But why should Mrs. Deline be interested in a common
+tramp?"
+
+"How do we know that fellow was a tramp?" Penny speculated. "Jerry told
+us about a young soldier that had escaped from a Canadian prison camp.
+Mrs. Deline may be trying to help him by supplying food and heavy
+clothing!"
+
+"As usual, Penny, aren't you leaping to hasty conclusions?"
+
+"Maybe I am, but everything fits in beautifully. I've thought from the
+first that Mrs. Deline was nothing less than a spy or an international
+crook."
+
+"You've aired that theory before," Louise said, stretching out on the
+cot. "Wonder when your father will get here?"
+
+"I wish he would come," Penny replied, glancing anxiously toward the
+road. "At least I have one consolation."
+
+"What's that?"
+
+"I know he's not with Mrs. Deline. Oh, Lou, think how horrible it would
+be to have a spy for a stepmother!"
+
+"It would be something different anyhow," Louise chuckled. "Want to
+listen to the radio awhile?"
+
+"Okay," Penny agreed, "maybe we can tune in that outlaw station. It's
+about time for the regular nightly broadcast."
+
+Closing themselves into the car, the girls tried without success to get
+the outlaw shortwave station. Tuning instead to a dance orchestra, they
+discussed the day's happenings and made elaborate plans for the morrow.
+
+"I'm really going to work," Penny announced grimly. "No Mrs. Deline ever
+will outwit me! Our first job must be to find that package she buried in
+the sand."
+
+"And what of the person hiding in the woods?"
+
+"The rangers ought to take over that part." Penny peered out through the
+car window at the dark woods which hemmed in the camp. "Somehow," she
+admitted, "I don't like the idea of being here at night. I'm not exactly
+afraid, but--"
+
+"Listen!" Louise ordered sharply, "Someone's coming!"
+
+Penny snapped off the radio. Tensely, the girls watched the road. The
+next instant they relaxed, for it was Mr. Parker who trudged wearily up
+the slope. Seeing Penny and Louise in the car, he came over to apologize
+for being so late.
+
+"I've been with Jerry for the past two hours," he explained. "Time went
+faster than I realized."
+
+"Any news?" Penny asked eagerly.
+
+"Not about the radio station if that's what you mean. The fellow got away
+with his portable outfit slick as a whistle."
+
+"The authorities have no idea who the man is, Dad?"
+
+"Not the slightest. So far they've not been able to break the code he
+uses either. But in time they'll get him."
+
+Having gleaned what information they could from Mr. Parker, the girls
+related their own adventure. As they fully expected, he made light of the
+episode at the cabin.
+
+"Why should Mrs. Deline expect to meet anyone there?" he argued. "Penny,
+I'm afraid you don't understand her and misinterpret her actions."
+
+"I don't understand her, that's certain."
+
+"As to a man loitering about the camp," Mr. Parker resumed, "I've been
+worried about that ever since food was stolen. As I must be gone so much
+of the time, why wouldn't it be better for us to move to the hotel?"
+
+Penny stiffened for an argument, and then suddenly changed her mind.
+
+"All right, Dad," she astonished him by saying, "as far as I'm concerned,
+we can move tomorrow. I've had enough of the lonesome life."
+
+"Why, that's fine!" Mr. Parker said heartily. "Splendid!"
+
+After he had moved on, to sit for awhile by the dying embers of the fire,
+Louise remarked to Penny that explanations were in order.
+
+"How come you're ready to desert the rough and rugged life?" she
+demanded. "At first you were dead set against moving into the hotel."
+
+Penny carefully raised the car window so that her father would not
+overhear.
+
+"I believe in fighting the Enemy on his own territory," she explained
+elaborately. "Mrs. Deline will bear watching. I intend to devote all my
+waking hours to the cause."
+
+"So Jerry has nothing to do with it?"
+
+"Jerry?"
+
+"You wouldn't want to move to the hotel so you'd see more of him?"
+
+"What an idea!" Penny scoffed. "Whoever thought of such a thing!"
+
+"You did or I'm no mind reader."
+
+"Well, it may have crossed my mind," Penny acknowledged with a giggle.
+"In fact, I can see quite a few advantages to hotel life. With luck we'll
+yet make something of this vacation!"
+
+
+
+
+ CHAPTER
+ 17
+ _VISITORS NOT PERMITTED_
+
+
+Penny stood before the mirror in the hotel room and struggled to coax a
+little curl into her damp hair. She and Louise had spent two hours
+splashing in the surf that morning. The salt water had tightened their
+skins and produced discouraging results with their tresses.
+
+"This place does have it over a forest camp," Penny said, gazing about
+the comfortably furnished room she shared with Louise. Her father's room
+was three doors down the hall. "A shower bath, no meals to cook, no
+dishes to wash, and the sea at one's elbow."
+
+"I like it better," replied Louise. She had curled up kitten fashion on
+the bed and was making deep inroads into a box of chocolates. "So far
+though, we've not done much fancy sleuthing."
+
+"We've only been here a few hours. Where do you suppose Mrs. Deline keeps
+herself?"
+
+"In her room no doubt. Why do you worry about her so much, Penny?"
+
+Penny twisted a few ringlets over her finger and abandoned the project as
+hopeless. "Lou, you know all the prize answers without asking me," she
+said. "I've told you a dozen times why I distrust that woman."
+
+"Doesn't it all simmer down to one thing? You're jealous as a green-eyed
+cat!"
+
+"Maybe I do dislike her," Penny grinned. "On second thought, I'm sure of
+it! But facts are facts and have nothing to do with my personal feelings.
+In the first place, didn't she get Dad to bring her with us to Sunset
+Beach?"
+
+"But what does that prove? She has no car of her own and the trains are
+so crowded."
+
+"I think she knew that Dad was coming here to try to dig up a story about
+the outlaw radio station," Penny went on, unruffled. "She's probably
+pumped him of information."
+
+"Your father knows how to look after himself."
+
+"That's what _he_ thinks!" Penny muttered. "I wouldn't place any wagers
+on it myself. Why, he's been as blind as a bat."
+
+"I'm afraid you see enough for two or three people," Louise chuckled.
+
+"I told you, didn't I, how that vampire tried to steal our car while we
+were on our way here?"
+
+"Two or three times, darling."
+
+"Well, it would bear repeating. I think she intended to meet someone that
+night--perhaps the same person who was hiding in the woods!"
+
+Louise, methodically eating chocolates, mulled over the possibility.
+
+"Jerry told us that an escaped flier from a Canadian prison camp may be
+hiding somewhere near here," Penny resumed, wandering to the window.
+"Perhaps Mrs. Deline is trying to help him!"
+
+"You have a new theory every minute," Louise yawned. "Why not think up
+one and stick to it?"
+
+Penny did not answer for at that moment she observed Jerry Livingston
+leaving the veranda of the hotel.
+
+"Come on, Lou!" she cried, jerking her chum off the bed. "I want to see
+Jerry before he escapes!"
+
+"Talk about Mrs. Deline pursuing your defenseless father!" Louise
+protested as she was pulled down the hall to the elevator. "Her tactics
+at least are more subtle than yours!"
+
+"This is different," Penny retorted shamelessly. "Jerry and I are old
+friends."
+
+Swinging through the revolving doors of the hotel, the girls raced after
+Jerry. Breathless from running, they finally overtook him far down the
+boardwalk.
+
+"Why, hello," he greeted them with a broad smile. "I hear you've moved
+into the hotel."
+
+"Lock, stock and barrel," Penny laughed. "We want to be in the thick of
+things. Any news about the radio station?"
+
+"Nothing I can report, I'm on my way now to Intercept Headquarters."
+
+"Did you see Dad this morning?"
+
+"Only for a few minutes. He's doing a little special work for me."
+
+"At least I'm glad it's for you and not Mrs. Deline," Penny said stiffly.
+"Jerry, there are some things you should know about that woman."
+
+"Suppose you unburden your heart," Jerry invited, seating himself on a
+sand dune. "I have about ten minutes to listen."
+
+"Don't encourage her," sighed Louise. "She's slightly cracked on the
+subject, you know."
+
+"Nevertheless, Penny has ideas at times," Jerry paid her tribute.
+"Shoot!"
+
+Talking like a whirlwind, Penny delved deeply into the subject of Mrs.
+Deline. She repeated how the widow had buried a package in the sand, but
+it was not until the episode of the cabin was described that Jerry really
+seemed interested.
+
+"Penny, at first I didn't take your Mrs. Deline talk very seriously," he
+admitted. "Perhaps you have something after all!"
+
+"I'm sure of it, Jerry!"
+
+"Have you reported to the park rangers?"
+
+"Dad may have seen them, I'm not sure. We left camp in a big rush."
+
+"Then I'll take care of that, Penny. We'll have the park searched again
+and try to find that fellow!"
+
+"Then you do believe he's the escaped flier!" Penny exclaimed.
+
+"Probably not," was Jerry's discouraging reply. "Nevertheless, we can't
+afford to overlook any possibility."
+
+"What about the package in the sand?"
+
+"You remember where it was buried?"
+
+"Approximately."
+
+"I'll not have time to go with you now," Jerry said, looking at his wrist
+watch.
+
+"Louise and I haven't much to do this morning. We'll be glad to search."
+
+"Go ahead," Jerry urged. "If you fail then I can take over. The important
+thing is not to tip off your hand. Don't let anyone suspect what you're
+about."
+
+Penny and Louise nodded soberly. They felt rather important to have been
+assigned a definite task.
+
+"Report to me as soon as you find that package," Jerry urged as he
+started on. "It may contain something of vital importance. It may not.
+We'll withhold judgment until we have the facts."
+
+Left to themselves, the girls lost not a moment in hastening to the
+section of beach where Mrs. Deline had been seen to bury the package.
+
+"Now just where was it?" Penny asked, gazing about the deserted dunes.
+"What became of our marker?"
+
+"We left a stick to show the exact spot."
+
+"Not a sign of it now. What wretched luck!"
+
+Though the girls knew the general locality where the package had been
+buried, all of the dunes looked discouragingly alike. Not a footprint
+remained to guide them.
+
+"I'll bet a cent Mrs. Deline came back here and removed that stick!"
+Penny declared. "Maybe she dug up the package too!"
+
+"Anyone could have taken the stick. Why do you think she did it?"
+
+"Because she watched us digging for the package. Well, let's look for it
+anyhow."
+
+With none too much enthusiasm, the girls set to work. The tide was much
+lower than upon their last visit and the shoreline did not look the same.
+Nor could they agree within forty feet of the right place to dig.
+
+"You try one dune, and I'll work on another," Penny offered as a
+compromise.
+
+An hour of unavailing work found the pair too discouraged to keep on
+digging.
+
+"If this is the right place, Mrs. Deline or someone has removed the
+package," Penny declared, sinking back on her heels.
+
+"We may as well give up," Louise added wearily.
+
+Penny slid down the dune and emptied sand from her shoes.
+
+"There should be an easy way to beat Mrs. Deline at her own little game,"
+she remarked thoughtfully. "For instance, why does she always wear that
+jade green charm?"
+
+"Because she likes it I'd imagine."
+
+"But wouldn't you think she'd take it off at night?"
+
+"Perhaps she does, Penny."
+
+"Not the night I was with her. I distinctly gained the impression that
+there was something about it she was afraid I'd see."
+
+"A message contained inside?"
+
+"That's been my theory from the first, Lou. Now if only we could lay our
+hands on the charm--"
+
+"Finding the package would be a lot easier. We can't waylay the woman and
+take the jade elephant by force. Or can we?"
+
+"No," Penny agreed reluctantly, "I don't think Dad would like that. And
+there's always the possibility I might be wrong."
+
+"The probability, you mean," corrected Louise.
+
+Penny retied her shoes and glanced toward the hotel. Far up the beach she
+saw Mrs. Deline, and the widow was walking slowly toward the sand dunes.
+
+"Duck!" Penny ordered, rolling over one of the high ridges. "We don't
+want her to see us here. She'll suspect what we've been up to."
+
+Louise crouched behind the dune with her chum, though she complained that
+she felt silly doing it. Apparently, Mrs. Deline had not seen the girls.
+She came steadily on.
+
+Drawing close, she peered directly at the dune where the girls had taken
+refuge. For a second they feared that she had seen them. But she passed
+on without another glance.
+
+"It looks to me as though she's on her way to the lighthouse again,"
+Penny remarked after Mrs. Deline was far down the beach. "Wonder why she
+goes there so often?"
+
+"I thought visitors weren't allowed."
+
+"According to the rules they're not."
+
+From behind the dune, the girls kept watch of the widow. Presently they
+saw her climb the steps of the lighthouse and disappear into the
+interior.
+
+"Well, that settles it!" Penny exclaimed indignantly.
+
+"Settles what?" Louise straightened up, brushing sand from her skirt.
+
+"If Mrs. Deline can get into that lighthouse, so can I. We'll make an
+issue of it!"
+
+"Not today," said Louise dubiously.
+
+"Right now!" Penny corrected, starting down the beach. "That lighthouse
+is government property, and as citizens we have certain rights. Let's
+assert them and see what happens!"
+
+
+
+
+ CHAPTER
+ 18
+ _INSIDE THE LIGHTHOUSE_
+
+
+Unchallenged, Penny and Louise reached the base of the lighthouse. But as
+they slowly climbed the iron stairs, their courage fast slipped away.
+
+"What will we say to the keeper?" Louise faltered. "I've even forgotten
+his name."
+
+"I haven't," said Penny. "It's Jim McCoy. If Mrs. Deline is allowed
+inside the tower, shouldn't we have the same privileges?"
+
+"She's a personal friend."
+
+"That should make no difference," Penny argued. "This is government
+property."
+
+"Let's not do it," Louise pleaded, holding back.
+
+Having proceeded so far. Penny was in no mood to retreat. Quickly, lest
+she too lose her courage, she rapped hard on the tower door.
+
+Minutes elapsed. Then the heavy oak door swung back and Jim McCoy, the
+burly keeper, peered out at the girls. His bushy brows drew together in
+an angry scowl.
+
+"You here again!" he exclaimed.
+
+"Yes," said Penny, making the word crisp and firm.
+
+"I'll have to report you if you keep pestering me," the keeper scolded.
+"How many times have I told you no visitors are allowed?"
+
+"But you don't treat everyone the same!" Penny remonstrated. "Mrs. Deline
+just came here."
+
+"Mrs. Deline? Who's she?"
+
+"Why, a woman who stays at the hotel. She came through this door not five
+minutes ago!"
+
+"You must have imagined it. I've had no visitors."
+
+Penny's silence said more plainly than words that she did not believe the
+keeper.
+
+"So you think I'm lying, eh?" he demanded unpleasantly. "Okay, come in
+and see for yourselves. I'm breaking a rule to invite you into the tower,
+but maybe then you'll be satisfied and quite bothering me. We have work
+to do here, you know."
+
+The keeper stepped aside so that the girls might enter.
+
+"My living quarters," he said curtly. "You see, I have no visitors."
+
+Decidedly ill at ease, the girls gazed about the little circular room.
+The walls were lined with built-in cupboards. Nearly all of the furniture
+had been made with a view to conserving space. As Mr. McCoy had said,
+there were no visitors--no evidence that Mrs. Deline ever had been there.
+
+"Are you satisfied?" the keeper demanded unpleasantly.
+
+"But we were sure Mrs. Deline came here," Penny stammered.
+
+"There's been no one today except early this morning when a government
+inspector paid me a visit."
+
+Penny did not believe the man but she deemed it wise to appear to do so.
+
+"I'm sorry," she apologized. "I guess we have made nuisances of
+ourselves."
+
+"That's all right," the keeper said in a less unfriendly tone. "Kids are
+kids. Now that you're here, look around a bit."
+
+"Oh, thank you," Louise replied gratefully. "I've always wanted to see
+the inside of a lighthouse."
+
+"I have some work to do," Mr. McCoy announced. "The light's not been
+operating right and I'm trying to get the mechanism adjusted. I'll be
+back."
+
+He went out, allowing the door to slam hard.
+
+The girls surveyed their surroundings with keen interest. On a table near
+the window there was a shortwave radio. A circular couch occupied another
+curving corner of the room.
+
+"What became of Mrs. Deline?" Penny whispered. "She certainly came here."
+
+"Of course she did! We saw her plain as day!"
+
+"She must be somewhere in the tower. Probably there's a room above this
+one."
+
+Penny tiptoed to the door and tried to open it. To her surprise and
+chagrin, it would not budge.
+
+"My Great Aunt!" she whispered. "We're locked in!"
+
+"Maybe the door's just stuck." Louise strode across the room to help
+Penny. Both of them tried without success to open it.
+
+"Let's shout and pound!" Louise suggested.
+
+"No, wait! I think we've been locked in here on purpose."
+
+"Oh, Penny!"
+
+"Now don't get nervous. The keeper's no fool. He'll have to let us out."
+
+"But why would he lock us in?"
+
+"Because he's provoked at us for one reason, Lou. Another, something's
+going on here that he doesn't want us to know about. He and Mrs. Deline
+may be having a tête-à-tête in the room above."
+
+"Then let's listen. Maybe we can overhear their conversation."
+
+Penny nodded and fell silent. Though the girls listened for a long while,
+no sound reached their ears.
+
+"This is a nice situation!" Louise fumed. "I think the door locked
+itself. We ought to shout for help."
+
+"Goose, a door doesn't lock itself."
+
+"This one might have a trick catch."
+
+"It was Mr. Jim McCoy who accomplished the trick," Penny said. "Listen!
+Someone's coming now."
+
+Plainly the girls could hear footsteps on the iron balcony outside the
+door. A moment later they were able to distinguish a murmur of men's
+voices. The footsteps moved on and a moment later they heard a door close
+overhead.
+
+"Another visitor!" Penny announced. "Did you hear what was said, Lou?"
+
+"Couldn't make out a word."
+
+"Nor could I. But that voice sounded familiar. I'm sure I've heard it
+somewhere."
+
+"I had the same feeling, Penny."
+
+The girls listened intently, hoping to overhear conversation on the floor
+above. However, the walls of the lighthouse were so thick that not a word
+reached them. Now and then they thought they heard Mrs. Deline's high
+pitched voice.
+
+"Louise, it's just come to me!" Penny whispered a moment later. "I
+believe Mr. McCoy's visitor may be George Emory!"
+
+"The voice did sound a little like his. But why would he come here?"
+
+"Maybe we've under-rated George Emory. Why, all this time he may have
+been trying to get information from us."
+
+"He did ask us quite a few questions, particularly about your father."
+
+"And he seemed to know a lot about that outlaw radio station, Lou. Maybe
+he tried to throw us off the track by suggesting that we watch old Jake
+Skagway."
+
+"We certainly fell for it, Penny."
+
+"We did, if you assume that George Emory is upstairs having a conference
+with Mrs. Deline and the lighthouse keeper. But we're not sure."
+
+"No, we're not, Penny. One easily can be mistaken in voices."
+
+Determined to hear more, Penny cautiously climbed up on the radio table,
+so that her head and ear were close to the ceiling.
+
+"Can you make out anything?" Louise whispered.
+
+Penny shook her head in disgust. After a few minutes she dropped lightly
+down from the table.
+
+"Walls are too thick," she announced. "I could hear three voices though.
+Two were men and the other, a woman."
+
+"Then Mrs. Deline must be here. The keeper lied about that part."
+
+Presently the girls heard footsteps again on the iron stairway. They
+moved to the window, hoping to see whomever was descending from the room
+above. However, the little round aperture was so situated that it gave a
+view of only one side of the Point. They could not see the stairway nor
+the stretch of beach leading to the hotel.
+
+"We're certainly learning a lot!" Louise said crossly. "I've had enough
+of this. Let's shout for help."
+
+"All right," Penny agreed. "We may as well find out whether or not we're
+prisoners."
+
+Crossing to the heavy oak door, she pounded hard on the panels. Almost at
+once the girls heard someone coming.
+
+"Don't let on what we suspect," Penny warned her companion.
+
+The next moment the door swung open to admit the keeper of the light.
+
+
+
+
+ CHAPTER
+ 19
+ _A LOCKED DOOR_
+
+
+"I was gone a little longer than I meant to be," Jim McCoy apologized as
+he came into the room. "Did I keep you waiting?"
+
+"We probably wouldn't have waited if you hadn't locked the door!" Louise
+said sharply.
+
+The keeper's eyebrows lifted and he looked slightly amused. "Locked in?"
+he echoed.
+
+"Yes, we couldn't get the door open."
+
+"Oh, it sticks sometimes. Been intending to fix it for several days. If
+you had pushed hard it would have opened."
+
+"We certainly pushed hard enough," Penny said dryly. She was more than
+ever certain that the lighthouse keeper had unlocked the door only a
+moment before entering. Clearly, he had meant to prevent Louise and her
+from seeing and hearing what went on in the room above.
+
+"Come along," the keeper invited. "I'll show you the tower."
+
+"No thank you," Penny replied coldly. "We've spent so much time here that
+we'll have to be getting back to the hotel."
+
+"As you like." The keeper shrugged, and looked relieved by the decision.
+
+Jim McCoy stepped away from the door, and the girls hastened down the
+iron stairway. No one was in sight on the beach. Whoever had visited the
+lighthouse during the time they were imprisoned, had disappeared.
+
+When they were well down the beach, Louise and Penny slackened their
+pace. Glancing back they saw that the keeper of the light still stood on
+the tiny iron balcony watching them.
+
+"That man gives me the creeps," Louise remarked. "Did you believe what he
+said about the door sticking?"
+
+"I did not," Penny returned with emphasis. "I think he locked us in on
+purpose, probably because he was expecting visitors and didn't want us to
+see too much."
+
+"As it turned out we didn't learn a thing."
+
+"We have no proof of anything," Penny admitted slowly. "Nevertheless,
+we're pretty sure Mrs. Deline visited the tower."
+
+"George Emory too."
+
+"That part is pure guess," Penny said, "so we don't dare consider it too
+seriously. Did you ever see Mrs. Deline with George Emory?"
+
+"Why, no. But then, we've not been at the hotel long."
+
+"Let's find Jerry or Dad," Penny said abruptly. "We ought to report to
+them."
+
+Returning to the hotel, the girls looked in vain for Mr. Parker. The
+publisher was not in his room nor anywhere in the lobby. Jerry apparently
+had not returned from Intercept Headquarters.
+
+"There's Mrs. Deline," Louise whispered, jerking her head toward a
+high-backed chair not far from the elevator.
+
+The widow was reading a newspaper. If she saw the girls she paid no
+attention to them.
+
+"Let's talk to her and see what we can learn," Louise suggested.
+
+Penny had another thought. "No," she vetoed the suggestion. "Mrs. Deline
+would be more likely to learn things from us. That woman is clever."
+
+Just then Mrs. Deline arose, picked up her purse, and went out the front
+door of the hotel. On their way to the elevator. Penny and Louise noticed
+that the woman carelessly had left a handkerchief and her room key lying
+on the chair.
+
+"I'll turn them in at the desk," Louise said, picking up the articles.
+
+"Wait, Lou!"
+
+Louise glanced at her chum in surprise.
+
+"I have an idea!" Penny revealed, lowering her voice. "Are you game to
+try something risky?"
+
+"Well, I don't know."
+
+"This chance is tailor-made for us!" Penny went on. "Mrs. Deline simply
+handed her room key over to us. Let's use our opportunity."
+
+"Enter her room?" Louise asked, shocked.
+
+"Why not? FBI agents think nothing of examining the belongings of a
+suspected person."
+
+"But we're not FBI agents, Penny. I don't want to do it without asking
+Jerry."
+
+"By that time it will be too late. It's now or never."
+
+"Mrs. Deline might catch us in the act."
+
+"That's a chance we'll have to take." Penny, in possession of the room
+key, walked to the front door of the hotel. She was reassured to see that
+Mrs. Deline had seated herself on a bench some distance from the veranda.
+
+"The coast's clear," Penny reported, coming back to Louise. "What do you
+say?"
+
+"Well, I suppose so," Louise consented nervously.
+
+An elevator shot the girls up to the fourth floor. To locate Mrs.
+Deline's room required but a moment, and the halls fortunately were
+deserted. Penny fitted the key into the lock and pushed open the door.
+
+"We'll have to work fast," she said, closing it behind them again.
+
+The room was in perfect order. Only a few toilet articles had been set
+out on the dresser. Mrs. Deline's suitcase was only half unpacked.
+
+"It looks to me as if the widow is holding herself ready to fly at a
+moment's notice," Penny commented. "Otherwise, why didn't she unpack
+everything?"
+
+"What do you expect to find here?" Louise asked nervously. "Let's get it
+over with fast, Penny."
+
+"Start with the bureau drawers," Penny instructed. "Search for any
+papers, letters or the sort. I'll go through the suitcase."
+
+Carefully the girls began examining Mrs. Deline's personal belongings.
+Almost at once Louise reported that the bureau contained nothing of
+interest. Penny, however, had more luck. She came upon a pearl-handled
+revolver buried beneath a pile of silk underclothing.
+
+"Jeepers!" she whispered, touching the weapon gingerly. "Now will you
+believe me when I say that the widow isn't the sweet little girl she'd
+have us believe!"
+
+Louise's eyes had opened wide at sight of the revolver.
+
+"And here's that white suit she wore!" Penny cried, lifting out a folded
+garment from the suitcase. "Look, Lou!"
+
+From the skirt of the suit had been cut a neat, square hole.
+
+"Well, of all things!" Louise exclaimed. "What's the meaning of that?"
+
+"Mrs. Deline wrote something on the skirt--don't you remember? Probably
+she used a pen with invisible ink."
+
+"But why on her skirt, Penny?"
+
+"She'd just been to the lighthouse. Perhaps she learned something there
+and she wanted to write it down before she forgot. Possibly she didn't
+have any paper. Then when she got back here, she either destroyed the
+message, or sent it to someone."
+
+"Well, I don't know," Louise said doubtfully. "It's all so fantastic. I
+wouldn't believe a bit of it except for this revolver. Having it doesn't
+look so good."
+
+"And don't forget the green elephant charm," Penny reminded her. "I wish
+we could find it here."
+
+"Not a chance. Mrs. Deline always wears it around her neck. She had it on
+today. I noticed."
+
+Time fast was elapsing and the girls were worried lest someone discover
+them in the room. Hastily they replaced everything as they had found it,
+and relocking the door, stepped out into the hall.
+
+"What's our next move?" Louise asked as they buzzed for a down-going
+elevator.
+
+"To tell Jerry and Dad, of course. But before that, there's one thing I
+wish we could do, Lou. It would give everything we have to report a more
+substantial basis."
+
+"What's that, Penny?"
+
+"Why don't we get our hands on the jade green elephant? I've a hunch that
+it contains something important--perhaps evidence that would crack the
+case wide open."
+
+"And just how do you propose that we acquire the charm?" Louise asked
+sarcastically. "Are we to waylay Mrs. Deline and take it by force?"
+
+"Afraid that wouldn't do."
+
+"There's no other way to get it. Mrs. Deline wears that charm as if it
+were her skin. I've never seen her without it."
+
+The elevator was coming down so Penny spoke hurriedly.
+
+"There is a way," she said softly, "if only it will work. Think we could
+get Mrs. Deline to go bathing in the surf with us?"
+
+"And ruin that lovely hair-do? Don't be silly."
+
+"All the same, it's worth trying," Penny urged. "Let's go to our room now
+and get our bathing suits."
+
+"I don't see any point in it."
+
+"You will," Penny laughed, entering the elevator. "If my little plan
+works we'll have keen sport and maybe do our country a good turn!"
+
+
+
+
+ CHAPTER
+ 20
+ _NYMPHS OF THE SEA_
+
+
+"How you expect to get Mrs. Deline to go swimming with us is beyond me!"
+Louise opined as she and Penny left the hotel, their bathing suits
+swinging over their arms. "It's none too warm today. She dislikes us both
+intensely. Furthermore, she never swims."
+
+"Any other reasons?" Penny asked cheerfully.
+
+"That should be enough."
+
+"Just wait and watch," Penny chuckled. "I just hope she doesn't suspect
+we've been prowling in her room. If she got wise to that she'd report us
+to the hotel management."
+
+Before leaving the hotel the girls had taken care to drop the room key in
+the chair where Mrs. Deline had left it. They were confident that no one
+had seen them take the key or enter the room.
+
+The widow remained as the girls last had seen her. She was sitting on a
+bench facing the sea, her gaze fixed on the deep blue line of the
+horizon. As the girls passed beside her, she looked up, frowning
+slightly.
+
+"We're on our way to the bath house," said Penny, her tone implying that
+the matter was one of great importance.
+
+"Really?" Mrs. Deline's voice barely was polite.
+
+"Wouldn't you like to come with us?" Louise invited cordially.
+
+The invitation took Mrs. Deline by surprise. "No, thank you," she
+declined. "I can't swim."
+
+"We'll teach you," offered Penny.
+
+"You're too kind. I don't care for the water. I particularly detest cold
+water."
+
+"The air is warming up," Penny tried to encourage her. "Why not try it
+with us?"
+
+"Nothing could induce me."
+
+Louise nodded grimly, as much as to say that she had known how it would
+be. Penny would not give up. She decided to adopt drastic measures.
+
+"No, I didn't suppose you would go into the water," she said. "You're
+probably afraid you'll get salt water on that lovely skin of yours, or
+muss up your hair."
+
+"Oh!" gasped Mrs. Deline. "The very idea!"
+
+"Isn't that the reason?" Penny pursued ruthlessly. "You have to protect
+your beauty?"
+
+"No, it's not the reason!" Mrs. Deline snapped. "If I had a bathing suit,
+I'd show you!"
+
+"You can use mine," Penny said promptly. "Louise has an extra one she'll
+let me have."
+
+Mrs. Deline looked trapped and angry. She sprang to her feet.
+
+"All right, I'll go swimming!" she announced. "If I catch pneumonia I
+suppose you'll be satisfied!"
+
+"Oh, you'll love the water once you're in," Penny said sweetly. "The bath
+house is this way."
+
+Mrs. Deline spent so long getting into the borrowed suit that the girls
+began to fear she had outwitted them. But just as they were ready to give
+up, the woman came out of the dressing room. Penny's suit was a size too
+small for her so that she looked as if she had been poured into it. Her
+legs were skinny, her hips bulged. She still wore the elephant charm.
+
+"Don't I wish Dad could see her now!" Penny muttered. "What a
+disillusionment!"
+
+Ignoring the girls, Mrs. Deline walked stiffly toward the surf. A wave
+rolled in, wetting her to the knees. Mrs. Deline shrieked and backed
+away.
+
+"It's freezing!" she complained.
+
+"You have to get wet all at once," Penny instructed kindly. "This way."
+
+She seized Mrs. Deline's hand and pulled her toward the deeper water.
+
+"Let me go!" Mrs. Deline protested, trying to shake free. "Stop it!"
+
+Penny held fast to her hand. A big roller broke over their heads. Mrs.
+Deline sputtered and choked and struggled.
+
+"Oh, this is dreadful!" she whimpered.
+
+"You have to watch for the waves and jump just as they strike you," Penny
+laughed. "Now!"
+
+She leaped, but the widow mistimed the roller. It struck her a resounding
+whack on her shoulders and head.
+
+"Oh! Oh!" she moaned.
+
+"Here comes another!" warned Louise. "A big one too!"
+
+Mrs. Deline broke away from Penny. She started to run for shore. The big
+roller overtook her, sweeping her from her feet.
+
+This was the opportunity that Penny awaited. Pretending that she too had
+lost her balance, she allowed the tide to carry her straight into Mrs.
+Deline. For an instant they both were beneath the surface of the water.
+
+Penny worked fast. Clutching Mrs. Deline as if in terror, she yanked hard
+at the slender chain that held the green elephant charm. It snapped and
+the jade piece came off into her hands. Deftly she thrust the charm into
+the front of her bathing suit. Then she popped up above the water,
+winking at Louise.
+
+Mrs. Deline scrambled to her feet, clutching at the broken chain.
+
+"See what you've done!" she accused Penny. "You pulled it apart. My
+beautiful charm has fallen into the water!"
+
+"Let me help you look for it," Louise offered, darting forward.
+
+As the pair were groping about on the sandy floor, another wave rolled
+in. Penny neglected to warn Mrs. Deline. It struck her from behind,
+toppling her over on her face. Her cap slipped awry and she swallowed
+salt water.
+
+"Oh, I can't stand any more of this!" she spluttered. "It was cruel of
+you to get me to come into the surf! Now I've lost my charm, and it was
+all your fault, Penny Parker."
+
+"I'll buy you another ornament," the girl offered. Seeing Mrs. Deline's
+distress she felt a bit ashamed of herself.
+
+"Another ornament!" the widow mocked. "I don't want another! I want the
+one I've lost. It's of vital importance to me to keep it."
+
+Mrs. Deline made another futile search for the charm.
+
+"It's been washed away," she cried. "I'll never find it now!"
+
+Glaring furiously at Penny, she turned and fled to the bath house.
+
+"Did she really lose the charm?" Louise demanded the moment the girls
+were alone. "Or did you get it, Penny?"
+
+Penny answered by producing the green elephant charm from the front of
+her bathing suit where she had hidden it.
+
+"Easy as taking candy from a babe," she chuckled. "My, but was she
+hopping mad!"
+
+"You may not be laughing if your father hears about this," Louise warned.
+"He's apt to look at matters from a different angle than we do."
+
+Penny skipped through the shallow water and sat down on the beach well
+beyond the reach of the waves. Louise flopped beside her. Eagerly they
+examined the jade green trinket.
+
+"Looks like any ordinary charm to me," Louise remarked. "No special
+carving."
+
+"It should open," Penny said. "The first night when Mrs. Deline and I
+shared a room, I was sure I saw her close it."
+
+Louise turned the charm over and pried at it with a hairpin.
+
+"It does have a back lid!" she exclaimed excitedly. "Penny, I think it's
+going to open!"
+
+"I'll say magic words while you work," Penny laughed. "Furthermore, I'll
+keep watch of the bath house. We don't want Mrs. Deline to pop out here
+and see us."
+
+Louise pried again at the lid of the charm. It gave suddenly.
+
+Inside the tiny cavity was a folded piece of paper. While Louise stared
+in delighted awe, Penny gained possession. With nervous haste she
+unfolded the paper. She gazed at it a moment and her face fell.
+
+"Why, I can't make anything of the writing!" she declared in
+disappointment. "The words don't make sense."
+
+"Just a mess of letters," Louise agreed, peering over her shoulder.
+
+The girls were decidedly let-down for they had gone to much trouble and
+risk to obtain the jade ornament. But Penny's disappointment did not last
+long. As she stared at the paper, its significance dawned upon her.
+
+"Why, this is important, Lou!" she cried. "Maybe we've stumbled into
+something big!"
+
+"How do you mean?"
+
+"Don't you see?" Penny demanded triumphantly. "The letters, of this
+message must comprise a secret code! If only we can break it down we may
+learn all we need to know about Mrs. Deline and her strange friends!"
+
+
+
+
+ CHAPTER
+ 21
+ _THE CARDBOARD BOX_
+
+
+While Penny and Louise were puzzling over the strange writing found
+inside the jade charm, Mrs. Deline appeared in the doorway of the bath
+house. Barely in time to escape detection, the girls hid the tiny
+elephant and the paper in the sand.
+
+Mrs. Deline crossed the beach to speak to the girls. Her hair was damp
+and stringy, her face pinched and blue from cold.
+
+"Here's your suit!" she snapped, slapping the wet garment into the sand
+at Penny's feet. "I hope you enjoyed the swim! I'm sure I didn't."
+
+Turning her back, the widow marched to the hotel.
+
+The moment Mrs. Deline had disappeared into the white brick building,
+Penny dug the jade elephant and paper from the sand.
+
+"Let's get dressed," she urged Louise. "We've no time to waste."
+
+So thrilled were the girls over what they had accomplished that they
+could talk of nothing else. Penny felt that by obtaining the jade
+elephant she had proven her case.
+
+"You thought I was only jealous of Mrs. Deline," she told Louise
+triumphantly as they dressed in adjoining booths. "Now what do you say?"
+
+"That you're a genius!" Louise praised. "Mrs. Deline certainly is mixed
+up in some shady business."
+
+Once dressed, the girls wrapped the jade elephant in a handkerchief and
+carried it to the hotel. Jerry was nowhere to be found, and a bellboy
+told Penny that her father had gone for a walk.
+
+"Perhaps we can work the message out ourselves," Penny suggested
+hopefully. "Let's try."
+
+In their hotel room, the girls spent an hour attempting to decipher the
+strange jargon of letters appearing on the paper. At the end of that
+time. Penny tossed aside her pencil in disgust.
+
+"This is a job for an expert," she declared. "I certainly don't classify
+as one."
+
+The telephone jingled. Penny answered it and was delighted to hear
+Jerry's familiar voice. He was down in the lobby and had been told that
+the girls wished to see him.
+
+"We certainly do!" Penny answered gaily. "Hold everything! We'll be with
+you in a jiffy."
+
+The elevator being entirely too slow, the girls raced down the stairs.
+Breathlessly they started to tell Jerry what they had learned.
+
+"Not here!" he said quickly. "Let's go outside where we won't be
+overheard."
+
+Once out in the open with no one close by, Jerry lent an attentive ear to
+Penny's tale of their afternoon adventure. He did not have much to say in
+return, but he studied the jade green elephant and the paper with deep
+interest.
+
+"You don't think it's anything?" Penny asked in disappointment.
+
+"On the contrary, it may be something of very great importance," he
+returned soberly. "I'll take this to Headquarters. We have an expert on
+codes who should be able to break it in a short while."
+
+The girls hoped that Jerry would invite them to accompany him, but he did
+not do so. Instead he said:
+
+"Penny, you were telling me that Mrs. Deline had buried a package in the
+sand. Any luck in finding it?"
+
+"Not a bit."
+
+"You don't think that she went back there and dug it up herself?"
+
+"We didn't see any footprints."
+
+"How did you mark the place?"
+
+"By a stick that someone removed."
+
+"Not a very reliable way to take observations," Jerry remarked. "Ever try
+the clock system?"
+
+The girls looked blank.
+
+"For example," Jerry illustrated, "imagine that the landscape is like the
+face of a clock. Now what do you see on the hour of two?"
+
+"I don't get it," Louise complained.
+
+"Oh, I do!" laughed Penny. "A big tree!"
+
+"That's right," agreed Jerry. "And at the hour of six?"
+
+"Why, a signboard!" chuckled Penny. "At the hour of seven there's a big
+sand dune!"
+
+"If you picture things in your mind as if they're on the face of a clock
+it's much easier to remember and keep them in proper proportion. Now,
+using that same system can you recall anything more about the place where
+Mrs. Deline buried the package?"
+
+"Not very much," Penny admitted. "I didn't take notations at the time."
+
+"Speaking of signboards, I remember one," Louise said thoughtfully. "It
+was a long distance back from the beach, slightly to the right. A
+cigarette advertisement."
+
+"That's right!" agreed Penny.
+
+"Perhaps that will help some," Jerry said. "We'll have to find the
+package."
+
+"Then you believe Mrs. Deline is an Enemy Agent?" Penny asked eagerly.
+
+"I've thought so for quite a while now," Jerry admitted. "I didn't say it
+for fear of building up your hopes. Anyhow, we've got to work quietly in
+this business."
+
+"Poor Dad," Penny murmured, "I'm afraid it will break him up to learn the
+truth. Do you say I should tell him right away, Jerry?"
+
+"Why not?" Jerry demanded, his eyes amused. "Your father may have a few
+things to break to you too, Penny."
+
+"Meaning what?"
+
+"I'll let your father do his own talking," Jerry said, getting up from
+the hotel bench. "Have to go now."
+
+"Wait!" Penny pleaded. "You've not told us anything. Do you think Mrs.
+Deline has been aiding that flier who escaped from a Canadian prison
+camp?"
+
+Jerry deliberately let the question pass. "Listen!" he said urgently. "I
+may not see you girls again until after dinner. Want to help me tonight?"
+
+"Doing what?" Penny asked.
+
+"I want you to lead me to the place where Mrs. Deline buried that
+package."
+
+"We'll do our best."
+
+"Then if I don't see you earlier, meet me here at nine o'clock. It should
+be dark by that time."
+
+"We'll be here," Penny promised, her eyes glowing.
+
+At dinner that night the girls told Mr. Parker of their appointment to
+meet Jerry. Penny would have explained about the package, but before she
+could do so, Mrs. Deline joined the group. Mr. Parker immediately invited
+her to dine with them. To the annoyance of Penny and Louise she accepted
+with alacrity.
+
+The girls fully expected that Mrs. Deline would make some reference to
+the incident of the afternoon. Instead she avoided the subject, talking
+of her experiences in China and the Orient. Despite their prejudice,
+Penny and Louise were compelled in all honesty to acknowledge to
+themselves that the widow was a brilliant, entertaining
+conversationalist.
+
+Over the coffee cups Mrs. Deline spoke casually of a play which was
+showing at the local theatre. Before Penny could say a word, Mr. Parker
+had suggested that he buy tickets for the night's performance.
+
+"I'd love to go," Mrs. Deline accepted instantly.
+
+"Good!" Mr. Parker, approved. "I'll get four tickets."
+
+"Two," Penny corrected grimly. "Louise and I already have an
+appointment."
+
+"That's so," Mr. Parker recalled belatedly.
+
+Mrs. Deline looked so pleased that Penny was sorely tempted to abandon
+the meeting with Jerry. Only the realization that the task ahead was
+vitally important, kept her silent.
+
+At eight o'clock Mr. Parker and Mrs. Deline left the hotel for the
+theatre. With an hour to kill, Penny and Louise were very restless. They
+read the evening paper and watched the clock.
+
+"Here's an interesting news item," Penny remarked, indicating a brief
+story on an inner page of the paper. "It says an enemy submarine was
+sighted not many miles from here--just off the coast."
+
+"Did they get it?" Louise inquired absently.
+
+"I guess not. The story doesn't say, except that the air patrol dropped
+bombs."
+
+"Wonder what a single sub was doing so close here?" Louise speculated.
+"Oh, well, we've nothing to fear."
+
+A clock chimed the hour of nine. On the first stroke, the girls arose and
+hastened to keep their appointment with Jerry. The night was closing in
+dark. Along the shore no lights were showing for the dim-out was rigidly
+enforced at Sunset Beach.
+
+"Where's Jerry?" Penny asked as they reached the bench where they had
+promised to meet him. "Hope he didn't forget."
+
+Ten minutes elapsed. Penny was examining the luminous dial of her wrist
+watch when someone came striding down the gravel path.
+
+"Hello," Jerry greeted the girls. "Sorry to have kept you waiting. All
+set for adventure?"
+
+"Lead on!" Penny laughed.
+
+Taking each of them by an elbow, Jerry guided the girls down the deserted
+beach. Twice they passed guards who merely stared and allowed them to
+pass unchallenged.
+
+"Any news about that code?" Penny questioned as they walked along.
+
+"It's a tough one to break," Jerry replied briefly. "Experts have been
+trying to take it apart ever since I left you girls this afternoon."
+
+"Then it really is something?" Penny asked, scarcely daring to hope.
+
+"It certainly is," Jerry replied heartily. "We're pretty sure now that
+Mrs. Deline is mixed up in a bad business. But we can't act until we know
+absolutely."
+
+"This will be a horrible shock to Dad," Penny remarked. "He's at the
+theatre with Mrs. Deline now."
+
+"At least she's out of the way, so there's no chance she'll see us at
+work," Jerry commented. "Think you can find the place to dig?"
+
+Penny had marked it well in her mind, but at night everything looked
+different. After some uncertainty, the girls agreed upon the dune where
+the package had been buried.
+
+"With the tide low we'll have plenty of time," Jerry said. "Well, let's
+go! Was the package buried deep?"
+
+"Not more than a foot," Penny supplied.
+
+"Then if it's here, we'll find it. Let's block this area off and cover it
+systematically."
+
+For an hour the trio toiled. Twice one of the beach guards passed by and
+Penny was surprised that he paid no heed to what they were doing.
+
+"Orders!" Jerry chuckled. "You didn't think we could come out here and
+prowl around without questions being asked? The guard was tipped off.
+He'll help us by whistling if anyone comes this way."
+
+Louise, who had been industriously digging, gave a low cry.
+
+"Find something?" Jerry demanded.
+
+"I'm not sure. I think so."
+
+The next instant Louise lifted a small package from its sand tomb. Before
+Jerry could warn her, she had torn apart the pasteboard cover.
+
+"Why, it contains pencils!" she exclaimed in disgust. "Pencils!"
+
+Jerry leaped to her side. One glance and he took the box from her.
+
+"Those objects may look like pencils," he drawled. "But take it from me,
+they're a bit more deadly."
+
+Penny had moved close. She and Louise stared in awe at the collection.
+
+"Bombs," Jerry explained briefly. "One of these little pencils contains
+enough explosive to blow us all to Kingdom Come!"
+
+
+
+
+ CHAPTER
+ 22
+ _UNFINISHED BUSINESS_
+
+
+The cardboard box contained in addition to the pencil bombs a shiny knife
+and several grooved, pear-shaped objects.
+
+"What are those?" Louise asked curiously. "They look like hand grenades."
+
+"That's what they are," said Jerry, lifting one from the box. "It's a
+mighty useful weapon for close fighting. A strong man can throw a grenade
+twenty-five to thirty-five yards and it does damage over a large area."
+
+Penny gingerly inspected one of the grenades.
+
+"It won't bite you," Jerry laughed. "Nor will it explode in your hand.
+When you're ready to throw a grenade you hold it with the lever under
+your fingers. Just before you toss it, pull the pin."
+
+"Isn't it apt to explode while you're holding it?" Penny asked dubiously.
+
+"Not while the lever is held. When the grenade leaves the hand, the lever
+flies off. Then the fuse ignites and in about seven seconds you have your
+explosion."
+
+"Nice little gadgets," Penny said. She replaced the grenade in its box
+and ran a finger over the sharp edge of the steel-bladed knife.
+
+"Mrs. Deline evidently planted these weapons here for someone else to
+use," Jerry remarked. "We'll put them back just as they were."
+
+"Put them back!" Penny echoed. "Why, Jerry, wouldn't that be playing
+right into their hands? Shouldn't we destroy these things?"
+
+"No, it's much wiser to have the place watched."
+
+Light dawned upon Penny. "Oh, I see!" she exclaimed. "In that way you
+hope to learn Mrs. Deline's accomplices!"
+
+"Exactly."
+
+Jerry replaced everything in the box which he carefully buried in the
+sand. Then he obliterated all freshly made footmarks.
+
+"It may be necessary to watch this place for days," he said thoughtfully.
+
+"And what of Mrs. Deline?" Penny asked. "Will she be allowed complete
+freedom?"
+
+"That's for my superiors to decide. It seems to me, though, that more is
+to be gained by allowing her to remain at liberty than by arresting her."
+
+"I'm all for jail myself," said Penny.
+
+"Just be patient," Jerry smiled. "And whatever you do, don't drop a hint
+to Mrs. Deline of what we suspect."
+
+"She knows I dislike her."
+
+"That's all right, but don't let her guess that you consider her guilty
+of anything more serious than making a play for your father."
+
+"What about Dad? Shouldn't I warn him?"
+
+"Let me take care of that part," Jerry smiled.
+
+"All right," Penny agreed reluctantly. "Just be sure that you don't muff
+it. Remember, you're playing with my future!"
+
+Jerry finished smoothing out the footprints in the sand and then escorted
+the girls to the hotel.
+
+"I must report to Headquarters without delay," he said, pausing at the
+hotel entrance. "Don't worry about the package. We'll have the place
+watched every minute."
+
+After Jerry had gone, Penny and Louise entered the hotel.
+
+"Is my father here yet?" Penny asked the desk clerk.
+
+"No, Miss. And there's a message for him. As soon as he comes in he's to
+call Major Gregg."
+
+Penny repeated the name thoughtfully. "That's a new one on me," she
+remarked. "Dad seems to have friends I know nothing about."
+
+"Oh, the Major comes to the hotel frequently," the clerk returned,
+smiling. "He and your father are well acquainted."
+
+As the girls crossed the lobby to a drinking fountain, Louise said
+teasingly:
+
+"I'm afraid you've lost track of your father lately, Penny. You've been
+so upset about Mrs. Deline that you've scarcely noticed anything or
+anyone else."
+
+"Dad's been holding out on me, that's evident. Wonder what he's to call
+Major Gregg about?"
+
+"Why not wait up and see?"
+
+"Not a bad idea," Penny approved instantly. "He and Mrs. Deline should be
+getting in anytime now."
+
+"I'm not waiting up," announced Louise with a sleepy yawn. "In fact, I'm
+on my way to bed this minute."
+
+To prove her words she started for the elevator. Penny debated whether or
+not to follow and finally decided to remain in the lobby.
+
+An hour elapsed. Penny was half asleep by the time Mrs. Deline and Mr.
+Parker entered the hotel together. They were chatting animatedly and
+would not have seen her had she not scrambled from the wing chair.
+
+Seeing Penny, Mrs. Deline quickly bade Mr. Parker good night and vanished
+into an elevator.
+
+"You shouldn't have waited up," Mr. Parker chided his daughter. "Why,
+it's nearly midnight."
+
+"There's an important message for you, Dad. You're to call Major Gregg."
+
+Mr. Parker looked disconcerted. "How long ago did that call come, Penny?"
+
+"About an hour ago. Or that's when I learned of it."
+
+Mr. Parker went quickly to a telephone booth and was gone for some time.
+When he returned his face was animated.
+
+"Good news?" Penny asked eagerly.
+
+"Not exactly," Mr. Parker replied, sliding into a chair beside her and
+dropping his voice. "A message from Interceptor Headquarters. Monitoring
+machines have traced the outlaw radio station again. The broadcast
+finished about an hour ago."
+
+"And where was the station located this time, Dad?"
+
+"Seemingly at or near the lighthouse."
+
+"The lighthouse!" Penny exclaimed. She was so startled that her voice
+rose to a high pitch, attracting the attention of a passing bellboy.
+
+"Not so loud, Penny," her father warned. "The strange thing was that the
+broadcast seemed to come from a cave, the same as before, although the
+monitoring machines charted it as being close to the lighthouse."
+
+"The only one I know about near the Point is Crystal Cave," Penny said
+thoughtfully. "Dad, maybe the broadcast did come from the lighthouse!"
+
+"That's government property. Penny, and the man in charge is beyond
+suspicion. Furthermore, the deep, echo effect couldn't come from anywhere
+except a cave."
+
+"Unless it were a sound effect, Dad."
+
+"What's that?" Mr. Parker asked, startled. "I don't get you, Penny."
+
+"I mean, maybe the cave set-up is just a sound effect and nothing more.
+Only the other night I heard one in a radio play and it sounded as if the
+actors really were in a cave. Isn't it done by an echo chamber or
+something of the sort?"
+
+"That would be possible," Mr. Parker agreed. "At Interceptor Headquarters
+it was assumed that a mistake had been made in charting the location of
+the station."
+
+"Then the lighthouse hasn't been investigated?"
+
+"Not to my knowledge."
+
+"Well, it should be!" Penny exclaimed. "Louise and I were there today and
+we saw--"
+
+"Yes?" Mr. Parker questioned as she suddenly broke off.
+
+"We saw a lot that didn't look right," Penny finished, deciding not to
+bring Mrs. Deline's name into the discussion. "Mr. McCoy had visitors and
+while they were there he kept us locked up."
+
+"My word! Why didn't you report to the police?"
+
+"Well, we weren't entirely sure," Penny said lamely. "The door just
+closed and locked, and Mr. McCoy let on that it had a trick latch. Then
+he released us, but not until after the visitors had gone."
+
+"Did you see the persons?"
+
+"No, we only heard their voices. We weren't able to overhear any of the
+conversation."
+
+Without explaining what he intended to do, Mr. Parker again closed
+himself into a telephone booth. Not until he returned did he tell Penny
+that he had called Interceptor Headquarters and that Army men had been
+sent to the lighthouse to make a thorough check-up.
+
+"Now it's late," he said briskly, "and you're overdue for bed, Penny.
+Better fly up."
+
+"Aren't you coming?"
+
+"Not just now. I have a little unfinished business."
+
+Penny hesitated, unwilling to go to bed when she sensed adventure in the
+offing. As she groped in her mind for an excuse to remain, the doors at
+the front entrance to the hotel began to spin. Jerry came hurrying into
+the lobby. Seeing Penny and her father he made a straight line for them.
+
+"The code's been broken!" he announced, addressing Penny.
+
+"What did they learn, Jerry?" she asked eagerly.
+
+"It's just as you thought, Penny." Jerry dropped his bombshell. "Mrs.
+Deline definitely is an Enemy Agent. Apparently she was sent to Sunset
+Beach to aid that escaped prisoner I told you about!"
+
+
+
+
+ CHAPTER
+ 23
+ _NIGHT ADVENTURE_
+
+
+As Jerry made the startling announcement, Penny glanced anxiously at her
+father. In the excitement of the moment she had not thought how much of a
+shock it might be to him to learn that Mrs. Deline was an agent employed
+by a foreign country. To her astonishment, he looked neither surprised
+nor dismayed.
+
+"So you have the proof, Jerry!" Mr. Parker exclaimed. "That's fine! But
+what's all this about a code? How did you stumble onto it?"
+
+"No time for details now," Jerry answered tersely. "Penny turned the
+trick--she and Louise saw Mrs. Deline bury a package in the sand."
+
+"And Mrs. Deline brought that package from the lighthouse," Penny
+interposed eagerly. "Mr. McCoy must have given it to her."
+
+"What's the plan of action?" Mr. Parker demanded. "Army men already have
+gone to the lighthouse to search that place thoroughly."
+
+"Our job is to keep watch of the dune where the package was buried.
+Naturally we have no way of knowing what time anyone will show up there.
+It may be an all night wait."
+
+"I'll be with you in a minute," Mr. Parker declared. "Just as soon as I
+get an overcoat."
+
+He started toward the elevator, then came back to the group.
+
+"What about Mrs. Deline?" he asked. "She's here in the hotel. Went to her
+room only a few minutes ago."
+
+"She'll be placed under arrest," Jerry said. "Better call her on the
+telephone and get her down here. Don't let her suspect that you think
+anything is wrong."
+
+Mr. Parker vanished into the nearest telephone booth.
+
+"I can't understand it," Penny murmured to Jerry. "I was sure Dad was
+head over heels in love with Mrs. Deline. Why, it didn't even seem to
+ruffle him when he learned the truth about her."
+
+Jerry grinned. "Maybe," he drawled, "that was because he knew all the
+time."
+
+Penny was dumbfounded. "You mean--" she stammered, "You mean that Dad's
+been acting a part? Pretending to admire Mrs. Deline while actually he
+didn't?"
+
+"Something like that. You see, your Dad became interested in the outlaw
+radio station and the men who operate it. By making inquiries before he
+left Riverview, he obtained information that made him think Mrs. Deline
+might be involved in some way. He knew she never had been in China but
+spent many years in Japan. He learned also that instead of being a
+newspaper correspondent, she had carried on secret work for various
+governments."
+
+"Dad knew all that! And he never let on to me!"
+
+"He couldn't very well, Penny. If you had guessed the truth, you'd have
+given it away by your manner--no matter how much you tried to act
+natural."
+
+"What a little nit-wit I've been!"
+
+"You have not," Jerry denied warmly. "Anyone else would have acted the
+same. Without knowing it, you helped your father a lot. You turned up
+evidence he never could have obtained alone."
+
+"Where do you fit into the picture, Jerry? Did Dad send for you?"
+
+"You don't send for anyone in the Army," Jerry explained, grinning. "By
+pure luck I was assigned here on a special mission. Your father learned I
+was coming, so we united forces."
+
+"Then you've both known from the first about Mrs. Deline?"
+
+"We've had a dark brown suspicion, Penny. But no proof until tonight."
+
+Penny drew a deep breath. Before she could ask another question, her
+father came hurrying down the hotel corridor.
+
+"Mrs. Deline's not in her room!" he reported. "She doesn't answer."
+
+"She went upstairs only a few minutes ago," Penny recalled.
+
+"Yes, she did, but she's not there now."
+
+"Maybe she's asleep," Jerry said, "and failed to hear the 'phone. We'll
+have to check."
+
+Without explaining why the matter was urgent, Mr. Parker arranged with
+the desk clerk to have one of the hotel maids go to Mrs. Deline's room.
+While the trio waited in the upstairs corridor, the woman rapped several
+times on the bedroom door, and failing to get a response, unlocked it
+with her master key.
+
+"Mrs. Deline!" she called, softly at first, then in a louder voice.
+
+There was no answer.
+
+The maid then snapped on the light. "Why, there's no one here!" she
+cried. "The bed's not been slept in!"
+
+"That's what I was afraid of," muttered Mr. Parker.
+
+With Jerry and Penny, he entered the bedroom. Everything was in perfect
+order. However, Mrs. Deline's suitcase was gone and all her belongings
+had been removed from the closet.
+
+"She's skipped without paying her room rent!" the maid exclaimed. "I'll
+call the manager!"
+
+Penny was peering into the waste paper basket beside the desk.
+
+"Look!" she drew the attention of her father and Jerry. "Burned letters
+and papers!"
+
+Digging into the basket, she brought up several charred sheets of paper.
+They were unreadable and crumpled in her hand.
+
+"This was a bad break for us--Mrs. Deline getting away!" Jerry exclaimed
+in disgust. "Evidently her work at Sunset Beach is finished. She's moving
+on to another pasture."
+
+"But she can't be far away," Penny reasoned. "After all, we know when she
+came to her room."
+
+"There still may be a chance to nab her," Mr. Parker said. "We'll notify
+the police to guard all the roads and the airport. I'll report to Major
+Gregg too."
+
+Without awaiting the arrival of the hotel manager, the trio hastened to
+the lobby. There Jerry and Mr. Parker made several telephone calls.
+
+"Now let's be on our way up the beach," Jerry urged anxiously. "We've
+killed too much time as it is."
+
+Penny half expected that her father would refuse permission for her to go
+along. To her delight he merely said:
+
+"I suppose there's no keeping you here, Penny. Well, come with us. I
+guess you've earned the right by your good work."
+
+It was a dark night, warm but misty. No lights were showing outside the
+hotel, though far up the beach the powerful lighthouse beacon cut swathes
+across the black sea.
+
+"What's the plan?" Mr. Parker asked Jerry.
+
+"The entire coast for fifty miles is being watched. I thought just on a
+chance we might keep vigil at the place where Mrs. Deline buried the
+package of explosives. Someone may show up there. On the other hand,
+Penny tipped off the fact that she knew where the bundle was buried."
+
+"Mrs. Deline watched Louise and me through a spy glass," Penny recalled
+ruefully. "She knew we didn't find the package though."
+
+"That's our assignment anyhow," Jerry said. "To keep watch of that
+particular place until relieved by Army men."
+
+The Parker car was on the hotel lot close by. Getting it, the trio took
+the beach road but stopped some distance from the lighthouse. Not wishing
+the car to attract the attention of any passer-by, it was left parked on
+a private driveway. Jerry, Penny and her father then crossed the dunes
+afoot and proceeded up the beach until they came to their station.
+
+"Think this is the place?" Penny asked skeptically.
+
+"I know it is," Jerry replied. "Remember what I told you about taking
+observations? Let's see if the package is still here?"
+
+He began digging in one of the dunes. Almost at once he came upon the box
+of explosives.
+
+"Exactly as we left it," he reported, replacing the sand. "No one's been
+here."
+
+"I doubt anyone will come," Mr. Parker commented. "Probably afraid."
+
+High overhead and out of sight, Penny heard the drone of planes on
+coastal patrol. She stared up into the dark sky and then toward the sea.
+The tide was coming in and long rolling waves washed the beach, dashed
+themselves on the shoreline and retreated.
+
+"We'll have to get down out of sight," Jerry warned. "Mustn't be seen
+from the road or the ocean either one."
+
+"How about this spot?" Mr. Parker suggested, pointing to a hollow between
+two giant dunes.
+
+The place seemed exactly right, so the trio flattened themselves on the
+sand. Jerry looked at the luminous dial of his watch.
+
+"One fifteen," he announced. "No sign of activity."
+
+"And no sign of any soldiers," Mr. Parker added. "I hope that whoever is
+to take over here shows up before long."
+
+"I don't," Penny said, snuggling close between her father and Jerry. "I'm
+having fun!"
+
+"If anything should develop, it's apt to be serious business," Jerry
+warned. "I'm inclined to think that we tipped our hand and nothing will
+happen."
+
+An hour elapsed. During that time there was no sound save the roar of the
+restless sea. The warm sand made a comfortable couch, and despite her
+best intentions, Penny caught herself dozing. She had all she could do to
+keep awake.
+
+"What time is it now?" she presently asked.
+
+"Two thirty-five," Jerry answered. "It doesn't look as if there's to be
+any activity, but then the night's young."
+
+"The night may be, but I'm not," Mr. Parker grumbled, shifting into a
+more comfortable position. "Wonder when our relief is to show up?"
+
+"Must be some mix up on orders. We're probably stuck here for the night."
+
+"In that case, Penny should return to the hotel."
+
+"Oh, no. Dad! Anyway, if I left now I might attract the attention of
+anyone watching this place."
+
+"You thought that one up!" her father chuckled. "Except for ourselves,
+there's no person within a quarter of a mile of this place."
+
+"You're wrong about that," murmured Jerry, stiffening to alert attention.
+
+"What's up, Jerry?" Mr. Parker said quickly. "You act as if you were
+seeing things!"
+
+"I am, Chief! Look to the right--between us and the lighthouse!"
+
+Mr. Parker and Penny gazed intently in the direction indicated.
+
+"Can't see a thing," Mr. Parker whispered. "Your eyes must be tricking
+you, Jerry."
+
+"Wait just a minute."
+
+Even as Jerry spoke, a shadowy figure emerged from the mists. The man
+came swiftly down the beach, making no sound as he walked. When he was
+very close, the revolving beacon of the lighthouse singled him out for a
+fleeting instant. Brief as was the moment of illumination, Penny
+recognized the man.
+
+"George Emory!" she whispered tensely. "What's he doing here?"
+
+
+
+
+ CHAPTER
+ 24
+ _OUT OF THE SEA_
+
+
+The answer to Penny's whispered question soon became obvious. George
+Emory looked carefully about the windswept beach. The three tense
+watchers thought that he might approach the dune where they lay hidden,
+but he did not.
+
+Instead, the man paused while several yards away and gazed toward the
+sea. A moment he stood thus, silhouetted against the sky. Then using a
+glowing flashlight, he began making wide sweeps with his arm.
+
+"A signal!" Jerry whispered. "He's trying to attract the attention of a
+boat out at sea!"
+
+"Shall we go for him?" asked Mr. Parker.
+
+"Wait!" Jerry advised. "He's not the only one we're after. We're stalking
+bigger game."
+
+At intervals for the next fifteen minutes, George Emory repeated the
+flashlight signals. Then he turned off the light and waited.
+
+Anxiously, Jerry, Penny and Mr. Parker kept their faces turned to the
+sea. They sensed that the hour of action was at hand, and it worried them
+that Army men had failed to arrive.
+
+"Look, Dad!" Penny suddenly whispered. She had glimpsed far from shore a
+long shadowy object which easily could be a boat. No lights were showing
+nor had she heard any sound.
+
+"I don't see a thing," Mr. Parker whispered back. "Yes! Now I do! Jove!
+It looks like a submarine that's surfaced. I can make out the conning
+tower!"
+
+"But why would it dare come here?" Penny speculated. "Won't it be
+detected by the patrol planes?"
+
+"Tonight's a bad night," Jerry pointed out. "Besides, the shore is so
+indented at this point of coast that perfect protection is almost
+impossible. They're sending a boat, that's sure!"
+
+A small craft had been launched from the wave-washed deck of the
+submarine. Manned by two men who rowed with muffled oars, it slowly
+approached the shore. When it was very close the watchers behind the sand
+dune saw by its grotesque sausage shape that it was a large, rubber boat.
+Like a gray ghost it slid over the water.
+
+Mr. Parker gripped Penny's hand in an encouraging squeeze.
+
+"Wish you were safe at the hotel," he whispered. "I was a fool to let you
+come."
+
+Penny's heart pounded but she shook her head vigorously. Not for anything
+would she have missed the adventure. However, she was cool headed enough
+to realize that the situation was not shaping up well for her father and
+Jerry.
+
+There were two men visible in the rubber boat, unquestionably armed. Then
+George Emory must be reckoned with and the arrival of others might be
+expected at any moment. Jerry carried a revolver but her father had no
+weapon. Already it was too late for any member of the trio to safely go
+for help.
+
+"That sub may intend to land Secret Agents here," Jerry speculated. "But
+from the code message we deciphered, it's more likely they plan to take
+aboard one or more passengers."
+
+"Perhaps that escaped flier," Penny supplied.
+
+"He's a valuable man to them. Well worth the risk they're taking to try
+to rescue him."
+
+"If passengers are to go aboard, where are they?" Penny whispered.
+"There's no one here but George Emory."
+
+"We must wait and watch. We'll soon see enough or I miss my guess."
+
+The rubber boat had reached the surf and was being churned by the waves.
+Two men in full military uniform, leaped out and guided the boat to the
+beach. George Emory waded out to meet them. Shaking the hand of each, he
+spoke rapidly in German. Though Mr. Parker understood the language, he
+was unable to catch a word.
+
+Tensely, the trio waited and watched. At any moment they feared that the
+men from the submarine might seek the cache of explosives hidden not far
+away. Soberly Jerry and Mr. Parker considered trying to reach the box in
+the sand. To do so they must cross an open, unprotected span of beach
+with every likelihood of being seen.
+
+"Let's wait and see what happens," Mr. Parker advised. "We shouldn't risk
+calling attention to ourselves."
+
+George Emory and his two companions obviously were awaiting someone.
+Nervously they paced the beach. Several times Mr. Emory looked at his
+watch. Then from far down the road came the sound of a car traveling at
+high speed. Tires screamed in protest as the auto came to a sudden halt
+on the paved road back from the beach.
+
+"That's why they've waited!" Jerry whispered.
+
+Barely a minute elapsed before two figures were seen coming swiftly from
+the direction of the road. A man and a woman crawled through the bushes,
+under the fence, and walked hurriedly across deep sand to the beach.
+
+"Mrs. Deline!" Penny identified the woman. "The man with her is the same
+fellow who stole food from our camp!"
+
+"I'd know his face from photographs I've seen," contributed Jerry. "He's
+Oscar Kleinbrock, escaped German prisoner. The man I was sent here to
+trace!"
+
+Mrs. Deline and her companion reached the group of men who awaited them.
+
+"You are five minutes late," George Emory reproved.
+
+"Can we help it?" Mrs. Deline snapped. "We're lucky to be here at all. Do
+you know that the road is being watched?"
+
+"By whom?"
+
+"Army men. We were nearly stopped but were able to turn off into the
+thicket and wait."
+
+"Then there's no time to waste in talk," George Emory said curtly.
+Turning, he spoke to the German flier in his own language.
+
+"He's telling him to get aboard the rubber boat," Mr. Parker interpreted
+tensely. "Now they're saying goodbye to Emory and Mrs. Deline."
+
+"Somehow we must hold them all here!" Jerry whispered grimly.
+
+"It's two against five. And they're armed."
+
+Mr. Parker and Jerry looked at each other, fully realizing how slim was
+their chance of success. They were not thinking of themselves but of
+Penny and what could happen to her if they failed. Mr. Parker touched her
+arm.
+
+"Penny," he whispered. "Slip away in the darkness and make a dash for the
+hotel. Jerry and I will try to hold them until help comes. Just keep low
+as you run or those fiends may take a pot-shot at you." Penny would not
+desert her father and Jerry. Stubbornly, she shook her head.
+
+"We want to know that you are safe," Jerry urged. "Please go while you
+still have a chance. You can help us most by bringing help."
+
+Penny's determination to remain, weakened. Yet reason told her she never
+could reach the hotel and return with help in time to do any good. It
+dawned upon her that Jerry was only saying what he did to get her safely
+away.
+
+"If only we had the box of explosives!" she whispered. "With it we might
+have a chance against those men!"
+
+"It's too late to dig up the box now," said Jerry. "We probably couldn't
+find it without a light. And the noise we'd make--"
+
+"Let me try," Penny interrupted.
+
+"All right, see if you can get your hands on the box," her father agreed
+suddenly. "Slip back of the dune, and then circle. Don't try to cross the
+beach. Be careful! Remember the least sound will bring a hail of
+bullets."
+
+Penny nodded and slipped away into the darkness, crawling on hands and
+knees. Barely had she left the shelter of the big sand dune than she
+heard two shots fired in quick succession.
+
+"Those came from Jerry's revolver!" she thought. "Oh, it was a trick to
+get me safely away! Now he and Dad are in for fireworks!"
+
+Raising her head above the protecting sand dune, Penny saw why Jerry had
+fired. The rubber boat was being launched. To delay the attack would mean
+that the entire party might escape.
+
+"They'll all get away!" Penny thought in dismay. "How can Jerry and Dad
+hold them single handed?"
+
+George Emory returned Jerry's fire with deadly aim. The bullets bit into
+the dune, throwing up little geysers of sand.
+
+"Launch the boat!" he shouted savagely to the men from the submarine.
+"Get away while you can! Be quick!"
+
+Jerry and Mr. Parker were determined that the party should not escape. As
+the men sought to launch the rubber boat, they made a concerted rush for
+the German flier who was to be taken aboard the waiting submarine. Caught
+by surprise, he went down beneath their blows.
+
+Fearful of hitting his own man, George Emory dared not fire again.
+Instead, he and the crewmen of the submarine fell upon Jerry and Mr.
+Parker. In the melee, one person could not be distinguished from another.
+
+"Fools! Fools!" cried Mrs. Deline as she watched the fierce, uneven
+struggle. "There is no time to be lost!"
+
+Jerry and Mr. Parker were putting up the fight of their lives, but they
+were no match for four able bodied, trained men. Penny, desperate with
+anxiety, saw that the struggle could end only in one way--disaster for
+Jerry and her father.
+
+"If I had that box of explosives maybe I could help them!" flashed
+through her mind.
+
+Rolling over a dune, she ran to the place near the fence where she
+thought the cache was buried. Frantically she clawed and dug at the sand.
+She could not find the box.
+
+"It must be here!" she told herself desperately. "Or was it hidden in the
+next dune?"
+
+She tried another place slightly to the right. As she dug, she heard a
+sound behind her. Turning swiftly, she saw Mrs. Deline starting across
+the beach toward her.
+
+"Oh, no, you don't!" the woman shouted.
+
+Penny's hand encountered something hard and firm. The box of explosives!
+Digging wildly, she lifted it from the bed of sand and sprang to her
+feet. Her fingers closed upon one of the hand grenades.
+
+"Get back!" she ordered Mrs. Deline, balancing herself as if to throw.
+
+The woman stopped short, then retreated a few steps. But only for a
+moment was she frightened.
+
+"Why, you infant, you couldn't throw a grenade!" she jeered. "You don't
+know how. Besides, you haven't the nerve!"
+
+"Get back!" Penny ordered again. "I warn you."
+
+Mrs. Deline laughed scornfully and came on.
+
+Even the thought of throwing a hand grenade terrified Penny. She knew
+that she could not deliberately harm Mrs. Deline or even the men who were
+mercilessly beating her father and Jerry. Yet she had to do something.
+
+"Maybe I can destroy the rubber boat!" she thought. "It's far enough away
+so that no one should be hurt by the explosion."
+
+Whirling away from Mrs. Deline, Penny faced the sea. Fixing her eyes on
+her target, the rubber boat at the water's edge, she hurled the grenade.
+
+"Idiot!" cried Mrs. Deline, flinging herself flat on the sand to protect
+her face from flying fragments.
+
+Penny did likewise. The grenade dropped with a thud on the sand beside
+the rubber boat. Her aim had been perfect. But there was no explosion.
+Belatedly, Penny realized that she had forgotten to pull the safety pin.
+
+Mrs. Deline kept her face buried beneath her arms and did not yet know
+what had happened. Sick with the knowledge that she had failed, Penny was
+desperate. Her father and Jerry were being cruelly beaten by their
+opponents. In another minute they would be overpowered and the Germans
+would escape to the waiting submarine.
+
+"I can't let them get away!" Penny whispered. "I must do something!"
+
+Remembering the pencil bombs, she groped in the cardboard box for them.
+They were not there. Instead, her fingers closed upon the sharp bladed
+knife.
+
+"I'll slash the rubber boat!" she thought. "I'll try to make a hole in
+it!"
+
+Before Mrs. Deline realized what the girl was about, Penny darted down
+the beach. The men from the submarine did not see her. Reaching the
+rubber boat, she leaped into it. Working with desperate haste, she jabbed
+the knife through the bottom. The material was tough and it took all of
+her strength to make a long jagged gash. Water seeped in, slowly at
+first, then faster.
+
+"I've done it!" Penny thought jubilantly. "I've done it!"
+
+Her triumph was fleeting. The next instant the girl was struck a hard
+stunning blow from behind. As she collapsed in a limp little heap on the
+sand, she dimly saw the cruel, angry face of Mrs. Deline. Then all went
+black and she knew no more.
+
+
+
+
+ CHAPTER
+ 25
+ _A SCOOP FOR UNCLE SAM_
+
+
+Penny opened her eyes and wondered where she was. For a moment she could
+remember nothing of what had transpired. Gradually, she realized that she
+was lying down, her head pillowed in someone's lap. She seemed to be in a
+fast-moving motor boat for she could hear the wash of waves against the
+craft. In panic she decided that she must be a prisoner enroute to the
+German submarine. She struggled to sit up.
+
+"Easy there, partner," said a soothing voice.
+
+Penny twisted sideways to look at the speaker. "Jerry!" she whispered.
+
+"You're all right," he said, pressing her gently back. "We'll get you to
+a doctor in a few minutes."
+
+"A doctor, my eye!" Penny protested with spirit.
+
+"That was a nasty blow Mrs. Deline gave you on the head," contributed
+another voice.
+
+Penny turned again and saw her father. His shirt was half torn off and
+there was a long gash on his cheek.
+
+"Dad, you're hurt!"
+
+"Nothing but a few scratches, Penny. Jerry took worse punishment than I
+did. But you should see the other fellows!"
+
+"What happened?" Penny asked. "Where am I anyhow?"
+
+"In a patrol boat bound for the hotel."
+
+"But what happened on the beach? The last I remember was when I tried to
+slash the rubber boat."
+
+"You not only tried, you did!" chuckled Jerry. "Mrs. Deline struck you on
+the head with something--maybe a rock--and you went down for the count.
+About that time, some of the Army boys arrived. Mrs. Deline and her crowd
+tried to make a get-away, but the boat couldn't be launched."
+
+"Then what happened?" Penny demanded as Jerry paused for breath.
+
+"The two members of the sub crew tried to swim. They were picked up by a
+patrol boat that had been drawn to the locality by the gun fire."
+
+"And Mrs. Deline?"
+
+"She and her pal Emory, together with the escaped flier, struck off
+across the sand dunes."
+
+"They didn't get away?"
+
+"Not on your life. They reached the road and there found a nice reception
+awaiting them! Right now the three are lodged at Headquarters."
+
+Penny took a deep breath. Her head was throbbing but she scarcely felt
+the pain.
+
+"What about Jim McCoy at the lighthouse?" she inquired.
+
+"He was taken into custody earlier in the evening. A portable
+broadcasting outfit was found on the premises."
+
+"Then Mr. McCoy really was the man responsible for those mysterious
+broadcasts--the Voice from the Cave?"
+
+"No doubt he had helpers," Mr. Parker contributed. "We expect to track
+down most of the ring now that the leaders have been captured. At any
+rate, we've put an end to the broadcasts. Your other theory was right
+too, Penny."
+
+"What theory, Dad?"
+
+"That the cave effect was produced by an echo chamber."
+
+"Then no broadcast ever originated in a cave?"
+
+"Probably not. We know McCoy shifted locations frequently. Tonight was
+the first time he ever dared broadcast from the lighthouse."
+
+"And what of the old beachcomber, Jake Skagway?"
+
+"Just a beachcomber," Jerry answered. "He had no connection with Emory or
+Mrs. Deline."
+
+Penny lay perfectly still for a few minutes, gazing up at the dark sky. A
+few stars pricked the black canopy above her, and now and then a quarter
+moon peeped from behind a cloud screen.
+
+"How did I get aboard this boat?" she presently inquired.
+
+"Another patrol boat came by," Jerry explained. "In fact, after all the
+fireworks, just about everyone in Sunset Beach arrived on the scene. We
+wanted to get you to a doctor so we took the first transportation that
+offered."
+
+"Almost there now too," added Mr. Parker.
+
+Penny sat up. The shore was dark but she could dimly see the dark Crystal
+Inn hotel.
+
+"I don't need a doctor," she laughed. "I'm feeling better every minute.
+My, won't Louise be green with envy when she learns what she missed!"
+
+"I'd say she was lucky," Mr. Parker corrected. "Penny, you don't seem to
+realize what a narrow escape we all had."
+
+"That's right," added Jerry, "those men were desperate, and they'd have
+stopped at nothing. I guess we owe our lives to you, Penny."
+
+Penny loved the praise. Nevertheless, she replied with a show of modesty:
+
+"Oh, I didn't do a thing, Jerry. As a matter of record, I nearly messed
+up the show. When I threw that hand grenade I forgot to pull the safety
+pin."
+
+"I'm glad you did," chuckled Jerry. "If it had exploded, we might not be
+here now."
+
+Penny sat very still, thinking over what had happened. Events were a bit
+hazy in her mind and many questions remained unanswered.
+
+"The submarine?" she asked after a moment.
+
+"Sunk," Jerry replied. "One of our patrol planes scored a direct hit."
+
+"I guess that brings me up to date," Penny sighed, "There's only one
+thing that bothers me."
+
+"What's that?" inquired her father.
+
+"Did you know who Mrs. Deline was when you invited her to come with us to
+Sunset Beach?"
+
+"No, but I had a healthy suspicion that she might be working against our
+country, Penny. I first met Mrs. Deline at the Club. However, she was
+rather transparent in making a play for my attention. In checking up I
+discovered that she never had been in China and never had written a
+newspaper story in her life. When she practically invited herself to ride
+with us to Sunset Beach, I thought I'd try to find out more about her
+little game."
+
+"I acted so silly about everything," Penny acknowledged, deeply ashamed.
+"I'm sorry, Dad."
+
+"You needn't be, Penny. At times you were rude to Mrs. Deline which was
+wrong. But your actions served a good purpose by keeping the woman so
+diverted that she never was on her guard."
+
+Shore was very close. As the powerful engines of the motor boat became
+muted, Penny said wistfully:
+
+"Now that your work is done here, Jerry, I suppose you'll be winging off
+to some far corner of the country."
+
+"Not for a few days at least," he reassured her. "I'm expecting a
+furlough and I'll spend it right here at Sunset Beach. We'll cram those
+days full of fun, Penny. We'll swim and golf and dance. We'll make every
+minute count."
+
+The boat grated gently against the dock and a sailor leaped out to make
+the craft fast. Mr. Parker and Jerry helped Penny ashore. Though she
+tried to stand steady upon her feet, the boards rocked beneath her.
+
+"Hook on," invited Jerry, offering an arm.
+
+Mr. Parker supported her on the other side, and thus they walked slowly
+toward the hotel.
+
+"The Three Musketeers!" chuckled the editor. "'One for all, and all for
+one.'"
+
+"We do make a trio," agreed Penny. "Tonight it seems just as it did when
+we were together in Riverview working on a big news story. There's one
+difference though."
+
+"What's that?" asked Jerry.
+
+"Tonight we were actors in a little drama that should be page one on any
+newspaper. Yet neither of you news hawks so much as spoke of trying to
+get a scoop for the _Riverview Star_."
+
+"Good reason," rumbled Mr. Parker. "The story of what happened tonight
+may never be published."
+
+"I understand, Dad. If the news were printed now it might give valuable
+information to the enemy."
+
+Penny paused to catch her breath. With Jerry and her father still
+supporting her, she turned to face the restless sea. The patrol boat had
+slipped away into the darkness. Far up shore, unmindful that her
+faithless master had gone, the bright beacon from the lighthouse swept
+the water at regular intervals. Nothing seemed changed.
+
+"Curtain going down on one of the best adventures of my life," Penny said
+softly. "Who cares that the _Riverview Star_ missed the story? Why, this
+was an A-1 scoop for Uncle Sam!"
+
+
+

+ Transcriber's Notes

+ the final book, "The Cry at Midnight".

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+

+<br /><i>AN UNINVITED GUEST</i></h2>
+<p>&ldquo;Mrs. Weems, what can be delaying Dad? He
+promised faithfully to be home by three o&rsquo;clock and
+it&rsquo;s nearly five now. Unless we start soon we&rsquo;ll never
+get to Sunset Beach tonight.&rdquo;</p>
+<p>Penny Parker, in blue slacks and a slightly mussed
+polo shirt, gazed disconsolately at the over-loaded automobile
+standing on the gravel driveway of the
+Parker home. Aided by Mrs. Weems, the family
+housekeeper, she had spent hours packing the sedan
+with luggage and camping equipment. Though the
+task long had been finished, Mr. Parker failed to arrive.</p>
+<p>&ldquo;Your father is a very busy man,&rdquo; Mrs. Weems responded
+to the girl&rsquo;s question. &ldquo;No doubt he&rsquo;s been
+held up at the office.&rdquo;</p>
+<p>&ldquo;Then why doesn&rsquo;t he telephone? It&rsquo;s driving me
+crazy to wait and wonder.&rdquo;</p>
+<div class="pb" id="Page_2">[2]</div>
+<p>Penny&rsquo;s freckled little face twisted into a grimace
+of worry. For weeks she and her father, editor-owner
+of the <i>Riverview Star</i>, had planned a vacation
+camping trip to the nearby seashore resort, Sunset
+Beach. Twice the excursion had been postponed.
+Penny, who knew well her father&rsquo;s habit of changing
+his mind, was fearful that even now something would
+cause another vexing delay.</p>
+<p>&ldquo;I&rsquo;m going to call the <i>Star</i> office this minute!&rdquo; she
+declared, starting for the house.</p>
+<p>Mrs. Weems busied herself gathering up loose odds
+and ends that had blown about the yard. She was
+cramming waste paper into a box when Penny banged
+out the door, her eyes tragic.</p>
+<p>&ldquo;I couldn&rsquo;t reach Dad!&rdquo; she announced. &ldquo;He left
+the office more than an hour ago.&rdquo;</p>
+<p>&ldquo;Then he should have been home before this,&rdquo; Mrs.
+Weems agreed.</p>
+<p>&ldquo;Something&rsquo;s happened. Maybe he&rsquo;s been run
+down by a car&mdash;&rdquo;</p>
+<p>&ldquo;Now Penny, stop such wild talk,&rdquo; the housekeeper
+interrupted sternly. &ldquo;You know better.&rdquo;</p>
+<p>&ldquo;But Dad was struck by an automobile last winter.
+What else could delay him?&rdquo;</p>
+<p>&ldquo;A dozen things,&rdquo; Mrs. Weems replied. &ldquo;Probably
+a business engagement.&rdquo;</p>
+<p>&ldquo;In that case, wouldn&rsquo;t he have telephoned me?&rdquo;</p>
+<p>&ldquo;Perhaps not. Now do stop fretting, Penny.
+Your father will be here before long.&rdquo;</p>
+<div class="pb" id="Page_3">[3]</div>
+<p>&ldquo;He&rsquo;d better be,&rdquo; Penny said darkly.</p>
+<p>Sitting down on the stone step by the door, she
+scuffed the toe of her tennis shoe back and forth in
+the gravel. Mrs. Weems who had cared for the girl
+ever since the death of Mrs. Parker, gazed at her
+sternly.</p>
+<p>&ldquo;Now do stop grieving!&rdquo; she chided. &ldquo;That&rsquo;s no
+way to act just because you&rsquo;re impatient and disappointed.&rdquo;</p>
+<p>&ldquo;But I&rsquo;ve been disappointed three times now,&rdquo;
+Penny complained. &ldquo;We planned on starting early
+and having a picnic lunch on the road. Dad promised
+faithfully&mdash;&rdquo;</p>
+<p>A car drove up to the curb at the front of the
+house. Penny sprang hopefully to her feet. However,
+it was not her father who had arrived. Instead,
+her chum, Louise Sidell, alighted and came running
+across the yard.</p>
+<p>&ldquo;Oh, I&rsquo;m glad I&rsquo;m not too late to say goodbye to
+you, Penny!&rdquo; she cried. &ldquo;How soon are you starting?&rdquo;</p>
+<p>&ldquo;I&rsquo;d like to know the answer to that one myself.
+Dad hasn&rsquo;t put in an appearance. He was due here
+at three o&rsquo;clock.&rdquo;</p>
+<p>&ldquo;Why, I saw him about twenty minutes ago,&rdquo;
+Louise replied, turning to inspect the over-loaded
+sedan. &ldquo;My, how did you accumulate so much luggage?&rdquo;</p>
+<div class="pb" id="Page_4">[4]</div>
+<p>Penny ignored the question to ask one of her own.
+&ldquo;Where did you see Dad, Lou?&rdquo;</p>
+<p>&ldquo;Why, riding in a car.&rdquo; Louise&rsquo;s dark eyes
+sparkled mischievously as she added: &ldquo;With a beautiful
+brunette too.&rdquo;</p>
+<p>&ldquo;You&rsquo;re joking.&rdquo;</p>
+<p>&ldquo;I am not. Your father was riding with Mrs. Deline.
+She&rsquo;s a widow, you know, and has lived in
+Riverview less than a month.&rdquo;</p>
+<p>Mrs. Weems, who had overheard the conversation,
+came over to the steps.</p>
+<p>&ldquo;Mrs. Deline, did you say?&rdquo; she inquired, slightly
+disturbed. &ldquo;I&rsquo;ve heard of her.&rdquo;</p>
+<p>&ldquo;And so have I!&rdquo; declared Penny with biting emphasis.
+&ldquo;Why, that woman would make the Merry
+Widow look like a dead number! She&rsquo;d better not
+try to sink her hooks into Dad!&rdquo;</p>
+<p>&ldquo;Penelope!&rdquo; the housekeeper reproved sternly.</p>
+<p>&ldquo;Well, you know what everyone says&mdash;&rdquo;</p>
+<p>&ldquo;Please don&rsquo;t repeat idle gossip,&rdquo; Mrs. Weems requested.
+&ldquo;I&rsquo;m sure Mrs. Deline is a very fine
+woman.&rdquo;</p>
+<p>&ldquo;She&rsquo;s the slickest serpent that ever free-wheeled
+into Riverview!&rdquo; Penny said heatedly. &ldquo;I saw her
+in action last week-end at the Country Club. Why,
+she simply went out of her way to cultivate any man
+who had an income of more than twenty-five thousand
+a year.&rdquo;</p>
+<div class="pb" id="Page_5">[5]</div>
+<p>&ldquo;Penny, your father is a sensible man,&rdquo; the housekeeper
+reproved. &ldquo;Unfortunately, it&rsquo;s a quality I&rsquo;m
+afraid you didn&rsquo;t inherit.&rdquo;</p>
+<p>Louise, unhappy to have stirred up such a hornet&rsquo;s
+nest, said hastily: &ldquo;Maybe it wasn&rsquo;t Mrs. Deline I
+saw. The car went by so fast.&rdquo;</p>
+<p>&ldquo;Oh, I&rsquo;m not worried. Dad can handle a bigger
+package of dynamite than Mrs. Deline. It just makes
+me irritated because he doesn&rsquo;t get here.&rdquo;</p>
+<p>Tossing her head, Penny crossed to the loaded
+automobile where she switched on the radio. She
+tuned it carelessly. After a moment a blurred voice
+blared forth:</p>
+<p>&ldquo;Attention Comrades!&rdquo;</p>
+<p>Penny turned quickly to glance at the dial, for she
+realized that she did not have the local station
+WZAM.</p>
+<p>&ldquo;Attention Comrades!&rdquo; the announcer commanded
+again. &ldquo;This is the Voice from the Cave.&rdquo;</p>
+<p>There followed a strange jibberish of words which
+were in no language that Penny ever before had heard.</p>
+<p>&ldquo;Mrs. Weems! Louise!&rdquo; she called excitedly. &ldquo;I
+think I&rsquo;ve tuned in an outlaw short wave station!
+Just listen!&rdquo;</p>
+<p>Louise and the housekeeper hastened over to the
+car. Penny tried desperately to tune the station in
+more clearly. Instead she lost it completely.</p>
+<div class="pb" id="Page_6">[6]</div>
+<p>&ldquo;Did you hear what that announcer said?&rdquo; she
+asked eagerly. &ldquo;Most of it I couldn&rsquo;t understand.
+I&rsquo;m sure it was in code!&rdquo;</p>
+<p>&ldquo;Code!&rdquo; Mrs. Weems exclaimed in amazement.</p>
+<p>&ldquo;I&rsquo;m sure I didn&rsquo;t have one of the regular stations!
+It must have been a short wave broadcast beamed at
+a particular group of persons. The announcer began:
+&lsquo;Attention Comrades!&rsquo;&rdquo;</p>
+<p>&ldquo;Can&rsquo;t you tune in again?&rdquo; Louise demanded.</p>
+<p>Penny twisted the dial without success. She was
+still trying when a taxi cab drew up at the front door.</p>
+<p>&ldquo;There&rsquo;s your father now!&rdquo; Louise declared.</p>
+<p>&ldquo;And see who&rsquo;s with him!&rdquo; Penny added, craning
+her neck. &ldquo;It <i>is</i> Mrs. Deline.&rdquo;</p>
+<p>Mrs. Weems, decidedly flustered, hurriedly removed
+her apron. In an undertone she warned Penny
+to be polite to the unexpected visitor.</p>
+<p>Mr. Parker, a tall, lean man with hair only touched
+by gray, stepped from the taxi. The woman he
+assisted was attractively slender, and dressed in an
+expensive tailored suit. Her face was cold and serene,
+but so striking that it commanded instant interest.
+Penny&rsquo;s spirits sagged as she observed that the widow
+came equipped with luggage.</p>
+<p>&ldquo;Now what?&rdquo; she muttered.</p>
+<p>Mr. Parker escorted Mrs. Deline across the yard,
+introducing her first to Mrs. Weems and then to the
+girls.</p>
+<div class="pb" id="Page_7">[7]</div>
+<p>&ldquo;Mrs. Deline is riding with us to Sunset Beach,&rdquo;
+he explained to Penny. &ldquo;She intended to go by train
+but failed to get a reservation.&rdquo;</p>
+<p>&ldquo;Coaches are so unbearable,&rdquo; Mrs. Deline said in an
+affected drawl. &ldquo;It was so nice of Mr. Parker to invite
+me to share your car.&rdquo;</p>
+<p>&ldquo;I&rsquo;m afraid it may not be so pleasant for you,&rdquo;
+Penny replied. She tried to speak cordially but the
+words came in stiff little jerks. &ldquo;There&rsquo;s not much
+room.&rdquo;</p>
+<p>&ldquo;Nonsense!&rdquo; said Mr. Parker. &ldquo;Mrs. Deline will
+ride up front. Penny, you&rsquo;ll have to battle it out with
+the luggage.&rdquo;</p>
+<p>By the time Mrs. Deline&rsquo;s suitcase and hat boxes
+were stowed away, there was indeed little room left
+in the rear seat for a passenger. Penny&rsquo;s face was
+very long. For weeks she had planned on a vacation
+trip with her father, and now all her plans had been
+shattered.</p>
+<p>&ldquo;Will you be staying long at Sunset Beach?&rdquo; she
+asked the widow politely.</p>
+<p>&ldquo;Probably a week,&rdquo; Mrs. Deline replied. &ldquo;I&rsquo;ve engaged
+a suite at the Crystal Inn. I&rsquo;m sure I couldn&rsquo;t
+endure a camping trip. Mosquitoes&mdash;hard beds&mdash;cooking
+over a camp fire&mdash;it all seems rather difficult
+to me.&rdquo;</p>
+<p>&ldquo;Oh, it will be fun to camp!&rdquo;</p>
+<p>&ldquo;I&rsquo;m not so certain of it myself.&rdquo; Mr. Parker
+assisted the widow into the front seat. &ldquo;Penny, why
+don&rsquo;t we ditch this camp stuff and try a hotel ourselves?&rdquo;</p>
+<div class="pb" id="Page_8">[8]</div>
+<p>&ldquo;No!&rdquo; answered Penny fiercely.</p>
+<p>&ldquo;It would be a far more sensible arrangement.&rdquo;</p>
+<p>&ldquo;But I don&rsquo;t want to be sensible,&rdquo; Penny argued.
+&ldquo;We&rsquo;ve planned on this trip for weeks, Dad.&rdquo;</p>
+<p>&ldquo;Oh, all right, if that&rsquo;s the way you feel about it,&rdquo;
+he gave in willingly enough. &ldquo;Only I never did care
+much for the rough and tumble life myself. Are we
+ready to start?&rdquo;</p>
+<p>&ldquo;Just a minute,&rdquo; Penny requested. &ldquo;I have to get
+my pocketbook from the house.&rdquo;</p>
+<p>She went indoors, her face as dark as a summer rain
+cloud. Mrs. Weems and Louise followed her in, corraling
+her in the kitchen.</p>
+<p>&ldquo;Now Penny, just a word of advice,&rdquo; the housekeeper
+cautioned. &ldquo;Mrs. Deline seems like a very
+nice woman. I trust that you&rsquo;ll be pleasant to her.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t see why Dad had to invite her! It&rsquo;s ruined
+everything!&rdquo;</p>
+<p>&ldquo;Aren&rsquo;t you being selfish?&rdquo;</p>
+<p>&ldquo;Maybe I am,&rdquo; said Penny. &ldquo;But why should I be
+crammed back with the pots and pans and luggage
+while she sits up front with Dad?&rdquo;</p>
+<p>&ldquo;Mrs. Deline is your guest.&rdquo;</p>
+<p>&ldquo;She&rsquo;s Dad&rsquo;s guest,&rdquo; Penny corrected. &ldquo;Furthermore,
+I suspect she invited herself.&rdquo;</p>
+<div class="pb" id="Page_9">[9]</div>
+<p>&ldquo;Whatever you think, I hope you&rsquo;ll keep your
+thoughts to yourself,&rdquo; Mrs. Weems said severely.
+&ldquo;I&rsquo;m really ashamed of you.&rdquo;</p>
+<p>The deep scowl disappeared from Penny&rsquo;s face and
+she laughed. Wrapping her arms about the housekeeper&rsquo;s
+ample waist she squeezed until it hurt.</p>
+<p>&ldquo;I know I&rsquo;m a spoiled brat,&rdquo; she admitted. &ldquo;But
+don&rsquo;t worry. I&rsquo;ll pretend to like Mrs. Deline if it
+kills me.&rdquo;</p>
+<p>&ldquo;That&rsquo;s much better, Penny. At any rate, you&rsquo;ll
+not be troubled with her company long. You&rsquo;ll reach
+Sunset Beach by nightfall.&rdquo;</p>
+<p>Penny made no reply. She turned to say goodbye
+to Louise.</p>
+<p>&ldquo;Wish you were going along,&rdquo; she said wistfully.
+&ldquo;A vacation won&rsquo;t seem fun without you.&rdquo;</p>
+<p>A staccato toot of the auto horn reminded Penny
+that her father and Mrs. Deline were waiting. Hurriedly
+she gathered up her purse.</p>
+<p>&ldquo;Have a nice time,&rdquo; Louise said, kissing her goodbye.
+&ldquo;And don&rsquo;t let Mrs. Deline get in your hair.&rdquo;</p>
+<p>Penny turned to make certain that Mrs. Weems
+was beyond hearing.</p>
+<p>&ldquo;Don&rsquo;t worry about that, Lou,&rdquo; she whispered.
+&ldquo;Mrs. Deline&rsquo;s already in my hair. What I&rsquo;m really
+worried about is keeping her from building a nest
+in it!&rdquo;</p>

+<br /><i>STORMY WEATHER</i></h2>
+<p>For an hour the Parker car had rolled smoothly
+along the paved road enroute to Sunset Beach. In
+the back seat, firmly wedged between boxes and suitcases,
+Penny squirmed and suffered.</p>
+<p>&ldquo;How much farther, Dad?&rdquo; she inquired, interrupting
+an animated conversation he was having with Mrs.
+Deline.</p>
+<p>&ldquo;Oh, about fifty miles,&rdquo; Mr. Parker tossed over his
+shoulder. &ldquo;We can&rsquo;t make much time at thirty-five
+an hour.&rdquo;</p>
+<p>&ldquo;How about lunch somewhere along the road?&rdquo;</p>
+<p>&ldquo;Well, should we take the time?&rdquo; the publisher
+asked. He turned toward his companion. &ldquo;What do
+you think, Mrs. Deline?&rdquo;</p>
+<p>&ldquo;Picnics always seemed stupid to me,&rdquo; she replied
+in a bored manner. &ldquo;Perhaps we&rsquo;ll find a nice tea
+house along the way.&rdquo;</p>
+<div class="pb" id="Page_11">[11]</div>
+<p>&ldquo;But Mrs. Weems prepared such a good lunch,&rdquo;
+Penny argued. &ldquo;I thought&mdash;&rdquo;</p>
+<p>&ldquo;We can use the food after we make camp,&rdquo; Mr.
+Parker decided briskly. &ldquo;A warm meal will be much
+better.&rdquo;</p>
+<p>Penny subsided into hurt silence. Since the party
+had left Riverview she felt that she had been pushed
+far into the background. Mrs. Deline had made no
+attempt to talk to her. On the other hand, the widow
+fairly hypnotized Mr. Parker with her dazzling smile
+and conversation.</p>
+<p>&ldquo;Dad,&rdquo; Penny began, determined to get in a word,
+&ldquo;just before you came home this afternoon, something
+queer happened.&rdquo;</p>
+<p>&ldquo;That so?&rdquo; he inquired carelessly.</p>
+<p>&ldquo;Yes, I turned on the radio, and a station I&rsquo;d never
+heard before came in. The announcer said: &lsquo;Attention
+Comrades, this is the Voice from the Cave.&rsquo;&rdquo;</p>
+<p>&ldquo;Sounds like a juvenile radio serial.&rdquo;</p>
+<p>&ldquo;Oh, but it wasn&rsquo;t, Dad! I&rsquo;m sure it was an outlaw
+station. Then the announcer spoke very rapidly in
+a language I&rsquo;d never heard before. It really sounded
+like code.&rdquo;</p>
+<p>&ldquo;Sure you didn&rsquo;t imagine it? You know you do
+get ideas, Penny. Especially when you&rsquo;re on the
+prowl for a mystery to solve.&rdquo;</p>
+<p>&ldquo;Aren&rsquo;t children quaint?&rdquo; Mrs. Deline laughed.</p>
+<div class="pb" id="Page_12">[12]</div>
+<p>Penny&rsquo;s lips tightened, but by great effort of will
+she kept silent. A child indeed! She knew now that
+Mrs. Deline disliked her and that they had launched
+an undeclared war.</p>
+<p>&ldquo;I heard the broadcast all right,&rdquo; she said. &ldquo;For
+that matter, so did Mrs. Weems and Louise. But
+probably it&rsquo;s of no consequence.&rdquo;</p>
+<p>The subject was dropped. It was stuffy in the
+closed car and Penny presently rolled down a window.
+Immediately Mrs. Deline protested that the
+wind was blowing her hair helter-skelter. At a stern
+glance from her father, Penny closed the window
+again, leaving only a tiny crack for air.</p>
+<p>&ldquo;All the way, please,&rdquo; requested Mrs. Deline.</p>
+<p>&ldquo;Penny, you&rsquo;re being very, very difficult,&rdquo; Mr.
+Parker added.</p>
+<p>Penny rolled the window shut, but her blue eyes
+cast off little sparks of fire. As a rule, she was a very
+pleasant person, not in the least spoiled. In Riverview
+where she had lived for fifteen happy, eventful years,
+her friends were beyond count. Penny liked people
+and nearly everyone liked her. But for some reason,
+she and Mrs. Deline had taken an instant dislike to
+each other.</p>
+<p>&ldquo;Maybe I&rsquo;m jealous,&rdquo; Penny thought ruefully. &ldquo;I
+shouldn&rsquo;t be, but Dad&rsquo;s all I have.&rdquo;</p>
+<div class="pb" id="Page_13">[13]</div>
+<p>Between Mr. Parker and his daughter there existed
+a deep bond of affection. Penny&rsquo;s mother was dead
+and the noted publisher had devoted himself to filling
+the great void in the girl&rsquo;s life. He had given her
+companionship and taught her to think straight.
+Knowing that she was dependable, he allowed her
+more freedom than most girls her age were permitted.</p>
+<p>Penny adored her father and seemingly had inherited
+his love of newspaper work. Upon various occasions
+she had helped him at the <i>Riverview Star</i>,
+writing and obtaining some of the paper&rsquo;s most spectacular
+front page stories. Only the past winter, following
+her father&rsquo;s severe illness, she had acted as
+editor of the <i>Star</i>, managing the paper entirely herself.</p>
+<p>&ldquo;And now Dad and Mrs. Deline treat me as if I
+were a child!&rdquo; she reflected resentfully.</p>
+<p>Though very much upset, Penny kept her thoughts
+to herself. Curling up with her head on a pile of
+blankets, she pretended to sleep.</p>
+<p>The car went over a hard bump. Penny bounced
+and opened her eyes. She was surprised to see that
+it had grown quite dark. The automobile was moving
+in a wide curve between long rows of pine trees.</p>
+<p>&ldquo;What time is it?&rdquo; she asked, pressing her face to
+the window.</p>
+<p>&ldquo;Not so late,&rdquo; replied her father. &ldquo;We&rsquo;re running
+into a rain storm. Just our luck.&rdquo;</p>
+<p>Dark clouds had entirely blotted out the late afternoon
+sun. Even as Mr. Parker spoke, several big
+raindrops splashed against the windshield.</p>
+<div class="pb" id="Page_14">[14]</div>
+<p>Soon the rain came down in such a thick sheet that
+the road ahead was obscured. Stopping suddenly for
+a crossroads traffic light, the car went into a slight
+skid. Mrs. Deline screamed in terror, and clutched
+Mr. Parker&rsquo;s arm.</p>
+<p>&ldquo;Oh, can&rsquo;t we stop somewhere?&rdquo; she pleaded. &ldquo;I&rsquo;m
+so afraid we&rsquo;ll have an accident.&rdquo;</p>
+<p>&ldquo;Yes, we&rsquo;ll stop,&rdquo; Mr. Parker agreed. &ldquo;The storm
+is certainly getting worse.&rdquo;</p>
+<p>A short distance ahead the party glimpsed a group
+of buildings. One was a filling station and beside it
+stood a small three-story hotel and tea room.</p>
+<p>&ldquo;Doesn&rsquo;t look too bad,&rdquo; Mr. Parker commented,
+pulling up close to the door. &ldquo;We&rsquo;ll have dinner and
+by that time the storm may be over.&rdquo;</p>
+<p>While Penny and Mrs. Deline went into the tea room,
+the publisher took the car next door to the
+filling station to have the tank refueled. He rejoined
+them soon, shaking the raindrops from his coat.</p>
+<p>&ldquo;It&rsquo;s coming down harder than ever,&rdquo; he reported.
+&ldquo;And we still have a long drive ahead of us.&rdquo;</p>
+<p>&ldquo;Do you think we&rsquo;ll reach our camp site tonight,
+Dad?&rdquo; Penny inquired anxiously.</p>
+<p>&ldquo;We&rsquo;ll be lucky to get to Sunset Beach. As for
+making camp, that&rsquo;s out of the question.&rdquo;</p>
+<p>&ldquo;Maybe it will stop raining soon,&rdquo; Penny ventured
+hopefully.</p>
+<div class="pb" id="Page_15">[15]</div>
+<p>Mr. Parker ordered dinner for the party and an
+hour was consumed in dining. The rain, however,
+showed no signs of slackening.</p>
+<p>&ldquo;We could go on&mdash;&rdquo; Mr. Parker said thoughtfully.
+&ldquo;Of course, the roads are slippery.&rdquo;</p>
+<p>&ldquo;Oh, please let&rsquo;s not venture out in this,&rdquo; Mrs.
+Deline pleaded before Penny could speak. &ldquo;I know
+I am being silly, but I&rsquo;m so afraid of an accident.
+Once I was in a car that overturned and I&rsquo;ve never
+forgotten it.&rdquo;</p>
+<p>&ldquo;There&rsquo;s no great hurry,&rdquo; Mr. Parker replied. &ldquo;If
+we can&rsquo;t reach Sunset Beach tonight, I suppose we
+could stay here.&rdquo;</p>
+<p>Mrs. Deline did not comment upon the suggestion,
+but from the way she smiled, Penny was sure that the
+idea appealed to her. Taking her father aside, the
+girl urged him to try to drive on to Sunset Beach that
+night.</p>
+<p>&ldquo;Our vacation is so short, Dad. Even now we&rsquo;ll
+lose almost a day in setting up camp.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll certainly push on if we can,&rdquo; he promised.
+&ldquo;This storm complicates everything.&rdquo;</p>
+<p>For two hours the rain fell steadily. With the
+prospects anything but improved, Mr. Parker made
+inquiry as to lodging for the night. From the hotel
+keeper he learned that rooms already were at a premium.</p>
+<div class="pb" id="Page_16">[16]</div>
+<p>&ldquo;We&rsquo;ll have to make up our minds soon,&rdquo; he reported
+to Penny and Mrs. Deline. &ldquo;If we wait much
+longer we&rsquo;ll probably find ourselves sleeping in the
+lobby.&rdquo;</p>
+<p>&ldquo;Then let&rsquo;s stay,&rdquo; the widow urged. &ldquo;Please engage
+a room and a bath for me. Preferably one at the
+rear of the building away from the highway.&rdquo;</p>
+<p>&ldquo;I&rsquo;m afraid you&rsquo;ll have no choice,&rdquo; Mr. Parker told
+her regretfully. &ldquo;We&rsquo;ll have to take what we can
+get.&rdquo;</p>
+<p>The publisher consulted with the hotel clerk, and
+returned to report that only two rooms remained
+available.</p>
+<p>&ldquo;You and Penny will have to share one together,&rdquo;
+he explained. &ldquo;I hope you won&rsquo;t mind.&rdquo;</p>
+<p>It was evident by the expression of Mrs. Deline&rsquo;s
+face that she minded a great deal. However, she
+consented to the arrangement and the luggage was
+taken upstairs. The door closed behind the bellboy.
+For the first time Penny and Mrs. Deline were left
+alone.</p>
+<p>&ldquo;Such a cheap, dirty hotel!&rdquo; the widow exclaimed
+petulantly. &ldquo;And I do hate to share a room with
+anyone.&rdquo;</p>
+<p>Penny busied herself unpacking her over-night bag.
+Crossing to the window, she raised it half way.</p>
+<p>&ldquo;Do put that down!&rdquo; Mrs. Deline ordered. &ldquo;I
+detest air blowing directly on me.&rdquo;</p>
+<p>Penny lowered the window.</p>
+<div class="pb" id="Page_17">[17]</div>
+<p>Mrs. Deline smoked a cigarette, carelessly allowing
+the ashes to fall on the bed. Getting up, she moved
+nervously about the room.</p>
+<p>&ldquo;This place is so small it seems like a prison,&rdquo; she
+complained. &ldquo;Why do you sit there and stare at me?&rdquo;</p>
+<p>&ldquo;I didn&rsquo;t realize I was staring,&rdquo; Penny apologized.
+&ldquo;If you&rsquo;ll excuse me, I&rsquo;ll go to bed.&rdquo;</p>
+<p>Undressing quickly, she crawled beneath the covers.
+Mrs. Deline smoked still another cigarette and
+then began to prepare for bed. As she removed the
+jacket of her suit, Penny noticed that the woman
+wore a beautiful jade elephant pin.</p>
+<p>&ldquo;Why, what an attractive ornament!&rdquo; she exclaimed.
+&ldquo;Is it a locket or just a pin?&rdquo;</p>
+<p>&ldquo;I bought it in China,&rdquo; the widow answered without
+replying to the question.</p>
+<p>&ldquo;In China! Have you been there?&rdquo;</p>
+<p>&ldquo;Of course!&rdquo; Mrs. Deline gave Penny an amused
+glance. Without removing the pin or offering to
+show it to the girl, she completed her preparations
+for bed.</p>
+<p>Just at that moment there came a light tap on the
+door.</p>
+<p>&ldquo;Oh, Penny!&rdquo; Mr. Parker called.</p>
+<p>&ldquo;Yes, Dad, what is it?&rdquo; Penny leaped out of bed.</p>
+<p>&ldquo;I&rsquo;m worried about the car keys,&rdquo; he called through
+the transom. &ldquo;You didn&rsquo;t by chance see them after
+we left the dining room?&rdquo;</p>
+<div class="pb" id="Page_18">[18]</div>
+<p>&ldquo;Why, yes,&rdquo; Penny reassured him. &ldquo;You left them
+lying on the table. I picked them up and forgot to
+tell you. They&rsquo;re here on the dresser. I&rsquo;ll hand them
+out.&rdquo;</p>
+<p>&ldquo;No, never mind. Keep them. I was just afraid
+they were lost. Goodnight.&rdquo;</p>
+<p>Mrs. Deline glanced curiously at the key ring on
+the dresser. She remarked that she had not seen
+Penny pick it up.</p>
+<p>&ldquo;You were talking to Dad at the time,&rdquo; the girl
+replied.</p>
+<p>Leaving the keys on the dresser, she leaped into
+bed again and settled herself for a comfortable sleep.
+Mrs. Deline presently turned out the light and took
+the other bed. For a time Penny was annoyed by
+voices from the hallway, then all became quiet. She
+slept.</p>
+<p>Much later Penny awoke. She stirred and rolled
+over. The rain had ceased and moonlight was flooding
+into the room. A beam fell directly across Mrs.
+Deline&rsquo;s bed, revealing a mass of crumpled sheets and
+covers.</p>
+<p>Penny stared, scarcely believing her eyes. The bed
+was empty.</p>
+<div class="pb" id="Page_19">[19]</div>
+<h2 id="c3"><span class="small">CHAPTER</span>
+<br /><span class="large">3</span>
+<br /><i>A JADE GREEN CHARM</i></h2>
+<p>Sitting up in bed, Penny gazed about the room.
+Mrs. Deline was not there and her clothes were gone
+from the chair where they had been placed earlier
+that night.</p>
+<p>&ldquo;Queer,&rdquo; mused the girl.</p>
+<p>Jumping out of bed, she darted to the door.
+Though it had been carefully locked a few hours
+before, the latch now was off.</p>
+<p>Thoroughly puzzled, Penny switched on a light
+and glanced carefully about. Mrs. Deline&rsquo;s suitcase
+remained in the closet, but coat and hat were missing.
+And then Penny made an even more disturbing discovery.
+The car keys were gone from the dresser!</p>
+<p>&ldquo;Why, I know I put those keys on the bureau just
+before I went to bed!&rdquo; she told herself in dismay.
+&ldquo;Now I wonder if that woman&mdash;&rdquo; Ashamed of her
+thoughts, she muttered: &ldquo;Guess I <i>am</i> a suspicious
+brat!&rdquo;</p>
+<div class="pb" id="Page_20">[20]</div>
+<p>Deeply mystified, she moved quickly to the window
+overlooking the parking lot and filling station.
+It was reassuring to see the Parker automobile standing
+where her father had left it earlier that night. But
+as she stood staring down into the dark, deserted
+yard, she was startled to observe a shadowy figure
+rounding a corner of the hotel.</p>
+<p>&ldquo;Mrs. Deline!&rdquo; she recognized the woman.</p>
+<p>Penny waited only long enough to see that the
+widow was walking straight toward the Parker sedan.</p>
+<p>&ldquo;She intends to steal it!&rdquo; thought the girl. &ldquo;Why
+else would she take the keys?&rdquo;</p>
+<p>Snatching dress and coat from a chair, Penny
+scrambled into them without taking time to remove
+her pajamas. She tucked up the unsightly legs of
+the garment and put on her shoes. Thus clad she ran
+downstairs through the semi-dark lobby to the side
+exit of the hotel.</p>
+<p>As she reached the outside door, she heard the blast
+of an automobile engine.</p>
+<p>&ldquo;That&rsquo;s our car!&rdquo; Penny thought, recognizing the
+sound of the running motor. &ldquo;She&rsquo;ll get away before
+I can stop her!&rdquo;</p>
+<p>The engine, evidently cold, sputtered a moment,
+then died.</p>
+<div class="pb" id="Page_21">[21]</div>
+<p>Hopeful that she might still get there in time, Penny
+raced across the parking lot. Reaching the car just
+as it started to move backwards, she jerked open the
+door.</p>
+<p>&ldquo;Mrs. Deline!&rdquo; she cried.</p>
+<p>Startled, the woman released the clutch so suddenly
+that the motor died again.</p>
+<p><a href="#front">&ldquo;Where are you taking our car?&rdquo; Penny demanded</a>,
+sliding into the seat beside the widow.</p>
+<p>The girl&rsquo;s unexpected arrival seemed to completely
+unnerve Mrs. Deline. She lost composure, but only
+for an instant. Lighting a cigarette, she gazed at
+Penny with cold disdain.</p>
+<p>&ldquo;I had intended to go for a little ride,&rdquo; she replied.
+&ldquo;Any objections?&rdquo;</p>
+<p>The question placed Penny on the defensive. &ldquo;You
+shouldn&rsquo;t have taken the car without asking Dad,&rdquo; she
+said stiffly. &ldquo;We barely have enough gasoline to
+reach Sunset Beach.&rdquo;</p>
+<p>&ldquo;Oh, I had no thought of going far. I&rsquo;ll just drive
+a few miles and come back.&rdquo;</p>
+<p>&ldquo;At this time of night? It must be nearly two
+o&rsquo;clock.&rdquo;</p>
+<p>&ldquo;I always enjoy night driving. Particularly if I
+am nervous and unable to sleep. Now run back to
+bed like a good child.&rdquo;</p>
+<p>Penny did not like the widow&rsquo;s tone of voice. She
+liked it less that Mrs. Deline ignored her hint that the
+car was not to be used. More than ever she was convinced
+that the woman had intended to steal the
+automobile.</p>
+<div class="pb" id="Page_22">[22]</div>
+<p>&ldquo;I&rsquo;m sorry,&rdquo; she said firmly. &ldquo;I must ask you not
+to take the car without Dad&rsquo;s permission.&rdquo;</p>
+<p>&ldquo;Well!&rdquo; Mrs. Deline exclaimed indignantly. &ldquo;You
+expect me to rap on your father&rsquo;s door at this time of
+night to ask if I may use the car!&rdquo;</p>
+<p>&ldquo;I don&rsquo;t see why you need to use the car at all.&rdquo;</p>
+<p>&ldquo;Oh, you don&rsquo;t?&rdquo; Mrs. Deline&rsquo;s tone was scornful.
+&ldquo;Well, let me tell you this! I&rsquo;ve already given
+you as much of an explanation as I intend to! I need
+the car.&rdquo;</p>
+<p>&ldquo;I thought you said you only intended to go for a
+little drive&mdash;to quiet your nerves,&rdquo; Penny reminded
+her.</p>
+<p>&ldquo;That&rsquo;s what I meant.&rdquo; Mrs. Deline tossed her
+cigarette through the open window and stepped on
+the car starter. &ldquo;I intend to go too.&rdquo;</p>
+<p>Penny, equally determined, switched off the ignition.</p>
+<p>&ldquo;Why, how dare you!&rdquo; Mrs. Deline turned furiously
+upon the girl. &ldquo;In all my life I never met such
+a spoiled child.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t mean to be rude, but I can&rsquo;t allow you to
+take the car.&rdquo;</p>
+<p>Mrs. Deline swung open the door on Penny&rsquo;s side
+of the seat. She reached as if to push the girl out of
+the car.</p>
+<div class="pb" id="Page_23">[23]</div>
+<p>Just then a man stepped from one of the hotel garages.
+Obviously he had been listening to the conversation,
+for he deliberately approached the car.</p>
+<p>&ldquo;Anything wrong here?&rdquo; he inquired.</p>
+<p>Penny recognized one of the night hotel clerks.
+She began to tell him of the disagreement between
+herself and Mrs. Deline.</p>
+<p>&ldquo;This child doesn&rsquo;t know what she&rsquo;s talking about!&rdquo;
+the widow declared irritably. &ldquo;Mr. Parker doesn&rsquo;t
+mind if I use the car.&rdquo;</p>
+<p>&ldquo;Then please ask him!&rdquo; Penny challenged.</p>
+<p>&ldquo;Why not allow me to do it for you,&rdquo; the hotel
+clerk offered. &ldquo;Wait here and I&rsquo;ll call Mr. Parker.
+He can settle the entire matter.&rdquo;</p>
+<p>&ldquo;No, don&rsquo;t bother him,&rdquo; Mrs. Deline decided suddenly.
+&ldquo;I&rsquo;ve changed my mind anyhow. After such
+a commotion I wouldn&rsquo;t enjoy a ride.&rdquo;</p>
+<p>&ldquo;In any case, I&rsquo;d prefer to call Mr. Parker,&rdquo; said
+the hotel man.</p>
+<p>&ldquo;Do,&rdquo; urged Penny in deep satisfaction. &ldquo;We&rsquo;ll
+wait here.&rdquo;</p>
+<p>&ldquo;I&rsquo;m going back to bed,&rdquo; Mrs. Deline announced,
+getting out of the car.</p>
+<p>She followed the hotel clerk into the building. Left
+in possession of the car, Penny reparked it and locked
+the doors. Then, feeling a trifle uneasy, she sauntered
+into the hotel.</p>
+<div class="pb" id="Page_24">[24]</div>
+<p>The lobby was deserted. Penny climbed the stairs,
+and in the hallway leading to her room, met her father
+and the hotel clerk. Summoned from bed, Mr. Parker
+garbed in dressing gown and slippers, looked more
+annoyed than alarmed.</p>
+<p>&ldquo;Penny, what is this I hear?&rdquo; he inquired. &ldquo;I can&rsquo;t
+get the straight of the story.&rdquo;</p>
+<p>Penny drew a deep breath. &ldquo;Well, it was this way,
+Dad. I awakened and discovered that Mrs. Deline
+had disappeared with the car keys.&rdquo;</p>
+<p>&ldquo;Mrs. Deline!&rdquo;</p>
+<p>&ldquo;Yes, I think she meant to steal the car. But she
+explained that she only intended to borrow it for a
+night ride.&rdquo;</p>
+<p>&ldquo;Anything wrong about that?&rdquo;</p>
+<p>Penny regarded her father in blank amazement.</p>
+<p>&ldquo;Why, Dad, would you borrow another person&rsquo;s
+car without asking?&rdquo;</p>
+<p>&ldquo;No, but Mrs. Deline probably didn&rsquo;t stop to consider
+the matter. No doubt she was too thoughtful
+to awaken you.&rdquo;</p>
+<p>&ldquo;Thoughtful, my left eye! Dad, I&rsquo;m sure Mrs.
+Deline meant to steal the car. Either that or she had
+a very important appointment&mdash;a meeting with someone
+she wasn&rsquo;t willing to tell us about.&rdquo;</p>
+<p>&ldquo;Nonsense!&rdquo; Mr. Parker exclaimed impatiently.
+&ldquo;Penny, you made a serious mistake in refusing to
+allow Mrs. Deline to use the car. She is our guest
+and I&rsquo;m afraid you were rude.&rdquo;</p>
+<div class="pb" id="Page_25">[25]</div>
+<p>&ldquo;But Dad&mdash;&rdquo;</p>
+<p>&ldquo;You must apologize to her at once.&rdquo;</p>
+<p>Penny did not answer for a moment. She bent
+to tie her flapping shoe strings and took her time at
+the task. When she straightened, she said quietly:</p>
+<p>&ldquo;All right, Dad. If you say so, I&rsquo;ll apologize. But
+I don&rsquo;t think I was wrong.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll not discuss it now, Penny. Suppose you
+turn the car keys over to me and go to your room.&rdquo;</p>
+<p>Penny gave up the keys and without another word
+went down the hall. Tears stung her eyes, but she
+brushed them away. She knew she had been unpleasant
+to Mrs. Deline. Nevertheless, she felt that her
+father had not been entirely just in his attitude.</p>
+<p>Entering the bedroom, she hesitated before turning
+on the light. Mrs. Deline had undressed and was in
+bed. She ignored the girl.</p>
+<p>&ldquo;I&mdash;I guess I made a bad mistake,&rdquo; Penny began
+awkwardly. &ldquo;I shouldn&rsquo;t have been so rude.&rdquo;</p>
+<p>Mrs. Deline rolled over in bed. Her dark eyes
+flashed and she made no effort to hide her dislike.</p>
+<p>&ldquo;So you admit it?&rdquo; she asked. &ldquo;Well, we will forget
+the matter. Do not speak of it to me again.&rdquo;</p>
+<p>In silence Penny undressed and hung up her coat
+and dress. As she prepared to snap out the light, she
+noticed that Mrs. Deline still wore the jade elephant
+charm about her neck.</p>
+<div class="pb" id="Page_26">[26]</div>
+<p>&ldquo;Aren&rsquo;t you afraid you&rsquo;ll break the chain?&rdquo; she
+asked before she thought. &ldquo;You forgot to take it off.&rdquo;</p>
+<p>Mrs. Deline raised herself on an elbow, fairly glaring
+at Penny.</p>
+<p>&ldquo;Will you kindly worry about your own affairs?&rdquo;
+she asked insolently. &ldquo;I&rsquo;ve had about all I can take
+from you in one night.&rdquo;</p>
+<p>&ldquo;But I didn&rsquo;t mean anything personal.&rdquo;</p>
+<p>&ldquo;Good night!&rdquo; said Mrs. Deline with emphasis.</p>
+<p>Penny turned out the light and crept into her own
+bed. She felt beaten and hurt. It was easy to understand
+why Mrs. Deline disliked her, but her own attitude
+was bewildering.</p>
+<p>&ldquo;I distrusted the woman the instant I met her,&rdquo; she
+reflected. &ldquo;Perhaps I had no reason for it at first.
+Now I&rsquo;m not so sure.&rdquo;</p>
+<p>Penny rolled over to face the window. Moonlight
+was flooding into the room. In the diffused light the
+girl could see Mrs. Deline plainly. The woman had
+propped herself up in bed and was fingering the jade
+green elephant charm which hung on its slender chain.
+Though Penny could not be certain, she thought the
+lid of the figure lay open and that Mrs. Deline quickly
+snapped it shut.</p>
+<p>&ldquo;Good night, Mrs. Deline,&rdquo; she ventured, still trying
+to make amends.</p>
+<p>The widow did not answer. Instead she turned her
+back and pretended to sleep.</p>
+<div class="pb" id="Page_27">[27]</div>
+<h2 id="c4"><span class="small">CHAPTER</span>
+<br /><span class="large">4</span>
+<br /><i>NO CAMPING ALLOWED</i></h2>
+<p>Breakfast the next morning was a trying ordeal
+for Penny. Over the coffee cups Mr. Parker
+apologized to Mrs. Deline for what he termed his
+daughter&rsquo;s &ldquo;inexcusable behavior.&rdquo;</p>
+<p>The widow responded graciously, quite in contrast
+to her attitude of the previous night. Without saying
+much, she conveyed the impression that Penny had
+been completely in the wrong, and was in fact, a
+spoiled child who must be humored.</p>
+<p>The journey on to Sunset Beach was equally unpleasant.
+Mr. Parker and Mrs. Deline seemed so absorbed
+in animated conversation, that they scarcely
+spoke or noticed Penny. Wedged between the luggage
+and the camping equipment, she indulged in self
+pity.</p>
+<p>&ldquo;At least we&rsquo;ll get rid of Mrs. Deline when we
+reach Sunset Beach,&rdquo; she cheered herself.</p>
+<div class="pb" id="Page_28">[28]</div>
+<p>Presently the car rounded a wide curve in the road,
+and Penny caught her first glimpse of the seashore.
+Big waves were rolling in, washing an endless stretch
+of white sand.</p>
+<p>&ldquo;Oh, isn&rsquo;t it beautiful!&rdquo; she exclaimed, brightening.
+&ldquo;I wish we were camping right on the beach
+instead of in the State Forest.&rdquo;</p>
+<p>&ldquo;I fear the authorities wouldn&rsquo;t permit that,&rdquo; Mr.
+Parker laughed. &ldquo;By the way, Penny, is your heart
+really set on this camping trip?&rdquo;</p>
+<p>Penny gave him a quick look. &ldquo;Yes, it is, Dad,&rdquo;
+she said briefly. &ldquo;Why do you ask?&rdquo;</p>
+<p>&ldquo;Well, I was thinking that we&rsquo;d be a lot more comfortable
+at one of the big hotels. We&rsquo;d be right on
+the beach and&mdash;&rdquo;</p>
+<p>&ldquo;Oh, I was just talking when I said I&rsquo;d like to camp
+on the beach,&rdquo; Penny cut in. &ldquo;I&rsquo;d like the State Forest
+much better.&rdquo;</p>
+<p>&ldquo;Then we&rsquo;ll go there just as we planned,&rdquo; Mr.
+Parker said, sighing. &ldquo;But you know I never was cut
+out for a rough and tumble life, Penny. I&rsquo;m far from
+sure I&rsquo;ll make a good camper.&rdquo;</p>
+<p>The car rolled on along the ocean road, presently
+entering the little village of Sunset Beach. Normally
+a tourist center, the town now was practically deserted,
+and the Parkers had chosen it because it was
+within easy driving distance of Riverview. Nearly
+all of the fine hotels along the water front were
+closed. However, the Crystal Inn remained in operation,
+and it was there that Mrs. Deline had engaged
+a suite.</p>
+<div class="pb" id="Page_29">[29]</div>
+<p>The car swung into the driveway and halted in
+front of the hotel. An attendant did not come immediately
+so Mr. Parker himself unloaded the widow&rsquo;s
+luggage. Mrs. Deline gave him a dazzling smile as
+she bade him goodbye.</p>
+<p>&ldquo;Oh, we&rsquo;ll not say goodbye just yet,&rdquo; Mr. Parker
+corrected. &ldquo;Penny and I will camp only a short distance
+away. We&rsquo;ll run down to the beach often.&rdquo;</p>
+<p>&ldquo;Do,&rdquo; urged Mrs. Deline. &ldquo;I have no friends here
+and I&rsquo;ll be happy to see you.&rdquo;</p>
+<p>Mr. Parker carried the widow&rsquo;s luggage into the
+hotel. While he was absent, Penny moved up to the
+front seat. She tuned in a radio program, listening
+to it with growing impatience. Finally her father
+sauntered out of the hotel.</p>
+<p>&ldquo;I nearly gave you up,&rdquo; Penny remarked pointedly.</p>
+<p>Mr. Parker slid behind the steering wheel and
+started the car. When they were driving along the
+ocean front road he said quietly:</p>
+<p>&ldquo;Penny, I can&rsquo;t imagine what has come over you
+lately. You&rsquo;re not in the least like the little girl who
+was my pal and companion. Why have you been so
+unkind to Mrs. Deline?&rdquo;</p>
+<p>&ldquo;I just don&rsquo;t like her,&rdquo; Penny said flatly. &ldquo;Furthermore,
+I distrust her.&rdquo;</p>
+<p>&ldquo;You&rsquo;ve acted very stupid and silly.&rdquo;</p>
+<div class="pb" id="Page_30">[30]</div>
+<p>&ldquo;I&rsquo;m sorry if you&rsquo;re ashamed of me,&rdquo; Penny replied
+glaring at her own reflection in the car mirror. &ldquo;At
+any rate, I saved the car for you.&rdquo;</p>
+<p>&ldquo;That accusation was ridiculous, Penny. Mrs.
+Deline is a wealthy woman who could buy herself
+a dozen cars in ordinary times. She merely gave in to
+a sudden whim.&rdquo;</p>
+<p>&ldquo;Just what do you know about Mrs. Deline, Dad?&rdquo;</p>
+<p>&ldquo;Not a great deal,&rdquo; Mr. Parker admitted. &ldquo;I met
+her at the club. She served as a special War correspondent
+in China, I believe. She has traveled all over
+the world and speaks a half dozen languages.&rdquo;</p>
+<p>&ldquo;I never heard of her until she came to Riverview,&rdquo;
+Penny said with a sniff. &ldquo;Nor did I ever see any of
+her writing in print. If you ask me, she&rsquo;s a phony.&rdquo;</p>
+<p>&ldquo;Let&rsquo;s not discuss the subject further,&rdquo; Mr. Parker
+replied, losing patience. &ldquo;When you&rsquo;re older, I hope
+you&rsquo;ll learn to be more gracious and charitable.&rdquo;</p>
+<p>Penny subsided into hurt silence. In all her life she
+could recall only a few occasions when her father had
+spoken so sternly to her. Close to tears, she studied
+the tumbling surface of the ocean with concentrated
+interest.</p>
+<p>In silence the Parkers drove through the village,
+stopping at a filling station to inquire the way to Rhett
+State Forest. Supplies were purchased at one of the
+stores, and by that time it was noon. At Mr. Parker&rsquo;s
+suggestion they stopped at a roadside inn for lunch.
+After that they drove on a half mile beyond the outskirts
+of Sunset Beach, past a tall lighthouse to the
+end of the pavement.</p>
+<div class="pb" id="Page_31">[31]</div>
+<p>&ldquo;We follow a dirt road for a quarter of a mile to
+Bradley Knoll,&rdquo; Mr. Parker said, consulting directions
+he had jotted down on an envelope.</p>
+<p>&ldquo;A mud road, you mean,&rdquo; Penny corrected, peering
+ahead at the narrow, twisting highway. &ldquo;It really
+rained here last night.&rdquo;</p>
+<p>The car had no chains. Not without misgiving,
+Mr. Parker drove off the pavement onto the slippery
+road. The car wallowed about and at times skidded
+dangerously.</p>
+<p>&ldquo;Once we reach the State park we&rsquo;ll have gravel
+roads,&rdquo; Penny said, studying a map.</p>
+<p>&ldquo;<i>If</i> we get there,&rdquo; Mr. Parker corrected.</p>
+<p>Barely had he spoken than the car went out of
+control. It took a long skid, turned crosswise in the
+road, and then the rear wheels slipped into a deep
+ditch. Opening the car door, Penny saw that the car
+was bogged down to the hub caps.</p>
+<p>Mr. Parker tried without success to pull out of the
+ditch. Alighting, he inspected the rear wheels which
+had spun deeper and deeper into the mud.</p>
+<p>&ldquo;Not a chance to get out of here without help,&rdquo;
+he said crossly. &ldquo;I&rsquo;ll have to find someone to give us
+a hand.&rdquo;</p>
+<div class="pb" id="Page_32">[32]</div>
+<p>Farther down the road stood a weatherbeaten farmhouse.
+Penny offered to go there to summon help,
+but her father insisted upon doing it himself. He
+presently returned with a farmer and a small tractor.
+After considerable difficulty the car was pulled out
+of the ditch.</p>
+<p>&ldquo;How much do I owe you?&rdquo; Mr. Parker asked the
+man.</p>
+<p>&ldquo;Ten dollars.&rdquo;</p>
+<p>The amount seemed far too high for the service
+rendered, but Mr. Parker paid it without comment.
+His shoes were caked with mud, and so were the
+trouser legs of his suit. Only by an effort of will did
+he keep his temper under control.</p>
+<p>&ldquo;Figurin&rsquo; on camping in the Rhett Forest?&rdquo; the
+farmer asked Mr. Parker.</p>
+<p>&ldquo;That&rsquo;s right. Is it much farther?&rdquo;</p>
+<p>&ldquo;Only a little piece down the road. You&rsquo;ll strike
+gravel at the next corner. You can make it if you&rsquo;re
+careful. I don&rsquo;t calculate you&rsquo;ll have much fun camping
+in the Park though.&rdquo;</p>
+<p>&ldquo;Why not?&rdquo; asked Penny.</p>
+<p>&ldquo;We&rsquo;ve had a lot o&rsquo; rain lately. The mosquitoes
+are bitin&rsquo; something fierce. And the ground&rsquo;s mighty
+damp.&rdquo;</p>
+<p>&ldquo;We have a floor to our tent,&rdquo; Penny said optimistically.
+&ldquo;I think camping will be fun. I&rsquo;ve always
+wanted to try it.&rdquo;</p>
+<div class="pb" id="Page_33">[33]</div>
+<p>The farmer started the tractor. &ldquo;Then don&rsquo;t let
+me discourage you,&rdquo; he shrugged. &ldquo;So long.&rdquo;</p>
+<p>Mr. Parker rejoined Penny in the car. &ldquo;Why not
+call this whole thing off?&rdquo; he suggested. &ldquo;We could
+go to the hotel and&mdash;&rdquo;</p>
+<p>&ldquo;No, Dad! You promised me!&rdquo;</p>
+<p>&ldquo;All right, Penny, if that&rsquo;s the way you feel, but I
+know we&rsquo;re asking for punishment.&rdquo;</p>
+<p>By careful driving the Parkers reached the gravel
+road without mishap. At the entrance to the Rhett
+Park area they were stopped by a pleasant, middle-aged
+forest ranger who took down the license number
+of the car.</p>
+<p>&ldquo;Be careful about your camp fire,&rdquo; he instructed.
+&ldquo;Only last week several acres of timber were destroyed
+at Alton. We&rsquo;re not certain whether it was
+started by a camper or was a case of sabotage. In any
+case, one can&rsquo;t be too careful.&rdquo;</p>
+<p>&ldquo;We will be,&rdquo; promised Mr. Parker.</p>
+<p>&ldquo;Camp only in the designated sites,&rdquo; the ranger
+added. &ldquo;I&rsquo;ll be around later on to see how you&rsquo;re
+getting along.&rdquo;</p>
+<p>Once beyond the gateway arch, Penny&rsquo;s sagging
+spirits began to revive. The road curled lazily between
+dense masses of timber fringed by artistic old-fashioned
+rail fences. Numerous signs pointed to
+trails that invited exploration.</p>
+<div class="pb" id="Page_34">[34]</div>
+<p>&ldquo;Oh, Dad, it&rsquo;s really nice here!&rdquo; she cried. &ldquo;We&rsquo;ll
+have a wonderful time!&rdquo;</p>
+<p>Presently the car came to an open space with picnic
+tables. There was a picturesque spot beside a rocky
+brook which looked just right for a camp site.</p>
+<p>&ldquo;Let&rsquo;s pitch our tent here!&rdquo; pleaded Penny. &ldquo;You
+set it up while I cook supper.&rdquo;</p>
+<p>Mr. Parker unloaded the car and went to work with
+a will hammering the metal stakes of the umbrella tent.
+Penny busied herself sorting pots and pans and trying
+to get the gasoline stove started. Despite her best
+efforts she could not induce it to burn.</p>
+<p>In the meantime, Mr. Parker was having his own
+set of troubles. Three of the tent stakes were missing.
+Twice he put up the umbrella framework, only to
+have the entire structure collapse upon his head.</p>
+<p>&ldquo;Penny, come here and help me!&rdquo; he called. &ldquo;I&rsquo;ve
+had about enough of this!&rdquo;</p>
+<p>Penny ran to her father&rsquo;s rescue, pulling the canvas
+from his head and shoulders. By working together
+they finally got the tent set up. Another half hour
+was required to put up the cots and make them.</p>
+<p>&ldquo;Well, that job is done,&rdquo; Mr. Parker sighed, collapsing
+on one of the beds. &ldquo;Such a life!&rdquo;</p>
+<p>&ldquo;Dad, I hate to bother you,&rdquo; Penny apologized,
+&ldquo;but I can&rsquo;t start the stove. Do you mind looking
+at it?&rdquo;</p>
+<div class="pb" id="Page_35">[35]</div>
+<p>Grumbling a bit, Mr. Parker went to tinker with
+the stove. Three-quarters of an hour slipped away
+before he succeeded in coaxing a bright flame.</p>
+<p>&ldquo;All this work has given me a big appetite for
+supper,&rdquo; he announced. &ldquo;What are we having,
+Penny?&rdquo;</p>
+<p>&ldquo;Steaks.&rdquo;</p>
+<p>&ldquo;Sounds fine.&rdquo;</p>
+<p>&ldquo;I forgot the salt though,&rdquo; Penny confessed, slapping
+the meat into a frying pan.</p>
+<p>The burner was too hot. While Penny had her
+back turned and was opening a can of beans, the
+steaks began to scorch. Mr. Parker tried to rescue
+them. In his haste he seized the hot skillet handle
+and burned his hands.</p>
+<p>&ldquo;Oh, Dad, I&rsquo;m so sorry!&rdquo; Penny sympathized. &ldquo;I
+guess the steaks are practically ruined too.&rdquo;</p>
+<p>&ldquo;Anything else to eat?&rdquo; the publisher asked, nursing
+his blistered hand.</p>
+<p>&ldquo;Beans.&rdquo;</p>
+<p>&ldquo;Beans!&rdquo; Mr. Parker repeated with bitter emphasis.
+&ldquo;Oh, well&mdash;dish them up.&rdquo;</p>
+<p>Penny was serving the food on tin plates when a
+car drove up and stopped. A ranger climbed out and
+walked over to the tent.</p>
+<p>&ldquo;What&rsquo;s the idea, camping here?&rdquo; he demanded.
+&ldquo;Can&rsquo;t you read signs?&rdquo;</p>
+<div class="pb" id="Page_36">[36]</div>
+<p>&ldquo;We didn&rsquo;t see any sign,&rdquo; said Penny.</p>
+<p>The ranger pointed to one in plain sight tacked on
+the trunk of a tree. It read:</p>
+<p>&ldquo;Restricted Area. No Camping Permitted.&rdquo;</p>
+<p>&ldquo;You can&rsquo;t stay here,&rdquo; the ranger added. &ldquo;You&rsquo;ll
+have to move on.&rdquo;</p>
+<p>Penny and her father gazed at each other in despair.
+After all the work they had done, it didn&rsquo;t seem as
+though they could break camp.</p>
+<p>&ldquo;Any objections if we stay here until morning?&rdquo;
+Mr. Parker requested. &ldquo;We&rsquo;ve had a pretty hard time
+of it getting established.&rdquo;</p>
+<p>The ranger looked sympathetic but unmoved.</p>
+<p>&ldquo;Sorry,&rdquo; he said curtly. &ldquo;Regulations are regulations.
+You may finish your supper if you like, then
+you must move on. The regular camp site is a quarter
+of a mile farther up the road.&rdquo;</p>
+<div class="pb" id="Page_37">[37]</div>
+<h2 id="c5"><span class="small">CHAPTER</span>
+<br /><span class="large">5</span>
+<br /><i>OVER THE AIR</i></h2>
+<p>The ranger&rsquo;s order so discouraged Penny and
+her father that they lost all zest for supper. Too
+weary for conversation, they tore up the beds, repacked
+the dishes, and pulled the tent stakes.</p>
+<p>&ldquo;I&rsquo;ve not worked so hard in years,&rdquo; Mr. Parker
+sighed. &ldquo;What a mistake to call this a vacation!&rdquo;</p>
+<p>&ldquo;Perhaps it won&rsquo;t be so hard once we get settled,&rdquo;
+Penny said hopefully. &ldquo;After all, we&rsquo;ve had more
+than our share of bad luck.&rdquo;</p>
+<p>Bad luck, however, continued to follow the campers.
+In the gathering darkness, Penny and her father
+had trouble finding the specified camp ground. It
+was impossible to drive a car into the cleared space,
+so they were forced to carry all of the heavy luggage
+and equipment from the automobile to the camp site.</p>
+<p>By that time it was quite dark. Mr. Parker misplaced
+one of the tent stakes and could not find it
+without a lengthy search. As he finally drove it in,
+he hammered his thumb instead of the metal pin.</p>
+<div class="pb" id="Page_38">[38]</div>
+<p>&ldquo;Drat it all! I&rsquo;ve had enough of this!&rdquo; he muttered
+irritably. &ldquo;Penny, why not give it up&mdash;&rdquo;</p>
+<p>&ldquo;Oh, no, Dad!&rdquo; Penny cut in quickly. &ldquo;Once we
+get the tent up again, we&rsquo;ll be all right. Here, I&rsquo;ll
+hold the flashlight so you can see better.&rdquo;</p>
+<p>Finally the tent was successfully staked down,
+though Mr. Parker temporarily abandoned the idea of
+putting up the front porch. Penny set up the cots
+again and made the beds.</p>
+<p>&ldquo;Hope you packed plenty of woolen blankets,&rdquo;
+Mr. Parker commented, shivering. &ldquo;It will be cold
+tonight.&rdquo;</p>
+<p>Penny admitted that she had brought only two
+thin ones for each bed. &ldquo;I didn&rsquo;t suppose it could
+get so cold on a summer night,&rdquo; she confessed ruefully.</p>
+<p>Worn by his strenuous labors, Mr. Parker climbed
+into the closed car to smoke a cigar. Penny, finding
+the dark tent lonesome, soon joined him there. She
+switched on the car radio, tuning in an orchestra.
+Presently it went off the air so she dialed another
+station. A strange jargon of words which could not
+be understood, accosted her ears.</p>
+<p>&ldquo;Hold that, Penny!&rdquo; exclaimed Mr. Parker.</p>
+<p>&ldquo;What station can it be?&rdquo; Penny speculated, peering
+at the luminous dial. &ldquo;It sounds like a short wave
+broadcast. Must be a station off its wave band.&rdquo;</p>
+<div class="pb" id="Page_39">[39]</div>
+<p>She and her father listened intently to the speaker
+who had a resonant, baritone voice. Not a word of
+the broadcast could they understand. Obviously a
+message was being sent in code.</p>
+<p>&ldquo;Dad, that sounds like the same station I heard yesterday!&rdquo;
+Penny broke in. &ldquo;Where can it be located?&rdquo;</p>
+<p>&ldquo;I&rsquo;d like to know myself.&rdquo;</p>
+<p>Penny glanced quickly at her father. His remark,
+she thought, had definite significance. Before she
+could question him, the strange jargon ceased. The
+deep baritone voice concluded in plain, slightly accented
+English: &ldquo;This is the Voice from the Cave,
+signing off until tomorrow night. Stand by, Comrades!&rdquo;</p>
+<p>&ldquo;That was no regular station,&rdquo; Penny declared,
+puzzled. &ldquo;But what was it?&rdquo;</p>
+<p>Mr. Parker reached over to turn off the panel
+switch. &ldquo;It was an outlaw station,&rdquo; he said quietly.
+&ldquo;The authorities have been after it for weeks.&rdquo;</p>
+<p>&ldquo;How did you learn about it?&rdquo;</p>
+<p>&ldquo;Through various channels. Most outlaw radio
+stations can be traced quite easily by the use of modern
+radio-detecting devices. The enemy agent who
+operates this station is a particularly elusive fellow.
+Just when the police are sure they have him, he moves
+to another locality.&rdquo;</p>
+<p>Penny was silent a moment and then she said:</p>
+<p>&ldquo;You seem to know quite a bit about this mysterious
+Voice, Dad.&rdquo;</p>
+<div class="pb" id="Page_40">[40]</div>
+<p>&ldquo;Naturally I&rsquo;ve been interested in the case. If the
+police catch the fellow it will make a good story for
+the <i>Star</i>.&rdquo;</p>
+<p>&ldquo;Where is the station thought to be located, Dad?&rdquo;</p>
+<p>&ldquo;Oh, it moves nightly. The fellow obviously has
+a portable broadcasting outfit.&rdquo;</p>
+<p>&ldquo;But isn&rsquo;t the general locality known?&rdquo;</p>
+<p>Mr. Parker smiled as he knocked ashes from his
+cigar.</p>
+<p>&ldquo;Authorities seem to think that it may be somewhere
+near here. Sunset Beach has countless caves,
+you know.&rdquo;</p>
+<p>&ldquo;Really?&rdquo; The information excited Penny. &ldquo;You
+never told me that before, Dad. And I suspect that
+you&rsquo;re keeping a lot of other secrets from me too!&rdquo;</p>
+<p>&ldquo;Sunset Beach&rsquo;s caves are no secret. They&rsquo;re part
+of the tourist attraction.&rdquo;</p>
+<p>&ldquo;All the same you never mentioned them, Dad. I
+thought it was odd that you chose this place for a
+vacation. Now I&rsquo;m beginning to catch on.&rdquo;</p>
+<p>Mr. Parker pretended not to understand.</p>
+<p>&ldquo;Isn&rsquo;t it true that you came here to do a bit of investigation
+work?&rdquo; Penny pursued the subject relentlessly.</p>
+<p>&ldquo;Now don&rsquo;t try to pin me down,&rdquo; Mr. Parker
+laughed. &ldquo;Suppose we just say we came here for a
+vacation.&rdquo;</p>
+<div class="pb" id="Page_41">[41]</div>
+<p>Penny eyed her father quizzically. From the way
+he sidestepped her questions she was certain that he
+had more than a casual interest in the outlaw radio
+station.</p>
+<p>&ldquo;Dad, will you let me help you?&rdquo; she pleaded
+eagerly.</p>
+<p>&ldquo;Help me?&rdquo; Mr. Parker joked. &ldquo;Why, you seem
+to think that I&rsquo;m a Government investigator in disguise!&rdquo;</p>
+<p>&ldquo;You don&rsquo;t deny that you came here largely because
+of your interest in that station?&rdquo;</p>
+<p>&ldquo;Well, I may be a tiny bit interested. But don&rsquo;t
+jump to conclusions, young lady! It doesn&rsquo;t necessarily
+follow that I have set out to track down any
+enemy agent single handed.&rdquo; Mr. Parker brought
+the discussion to an end by opening the car door.
+&ldquo;I&rsquo;m dead tired, Penny. If you&rsquo;ll excuse me, I&rsquo;ll
+turn in.&rdquo;</p>
+<p>After her father had gone to the tent, Penny remained
+for a while in the car. Soberly she stared at
+the stars and thought over what she had learned.</p>
+<p>&ldquo;I don&rsquo;t care what Dad says,&rdquo; she reflected, &ldquo;he
+came here to find that radio station! But maybe, just
+maybe, I&rsquo;ll beat him to it!&rdquo;</p>
+<div class="pb" id="Page_42">[42]</div>
+<h2 id="c6"><span class="small">CHAPTER</span>
+<br /><span class="large">6</span>
+<br /><i>BREAKFAST BLUES</i></h2>
+<p>Penny awoke next morning to find the tent
+cold and damp. She rolled over on the hard cot and
+moaned with pain. Every muscle in her battered
+body felt as if it had been twisted into a knot.</p>
+<p>Swinging her feet to the canvas floor, she pulled
+away the curtain to peer at her father&rsquo;s cot. It was
+empty.</p>
+<p>&ldquo;Guess I&rsquo;ve overslept,&rdquo; she thought. &ldquo;Hope Dad&rsquo;s
+started breakfast.&rdquo;</p>
+<p>Penny dressed quickly, cringing as she pulled on
+damp shirt and shorts. Dew lay heavy upon the tent
+and the grass outside was saturated. She walked gingerly
+as she picked her way toward the parked car.</p>
+<p>Mr. Parker had set up a portable table nearby and
+was tinkering with the gasoline stove. He was unshaven
+and looked very much out of sorts.</p>
+<div class="pb" id="Page_43">[43]</div>
+<p>&ldquo;Hi, Dad!&rdquo; Penny greeted him with as much cheer
+as she could muster. &ldquo;What are we having for breakfast?&rdquo;</p>
+<p>&ldquo;Nothing, so far as I can see! This stove is on
+strike again. I&rsquo;ve tried for half an hour to get it
+started.&rdquo;</p>
+<p>Penny climbed into the car to use the mirror. The
+sight of her face horrified her. One cheek was
+blotched with ugly red mosquito bites, there were
+dark circles under her eyes, and her hair hung in
+strings.</p>
+<p>&ldquo;If anyone ever gets me on another camping trip
+I&rsquo;ll be surprised!&rdquo; Mr. Parker exclaimed. He slammed
+the stove down on the table. &ldquo;I&rsquo;m through monkeying
+with this contrary beast!&rdquo;</p>
+<p>&ldquo;Oh, Dad, such a temper,&rdquo; Penny chided, giggling
+despite her own discouragement.</p>
+<p>&ldquo;Suppose you suggest how we&rsquo;re to eat.&rdquo;</p>
+<p>&ldquo;Well, there&rsquo;s cold breakfast food with canned
+milk.&rdquo; Penny burrowed deep in a box of supplies
+stored in the car. &ldquo;Two soft bananas. No coffee,
+I&rsquo;m afraid.&rdquo;</p>
+<p>&ldquo;Wonderful!&rdquo; Mr. Parker said grimly. &ldquo;Well,
+bring on the bird food.&rdquo;</p>
+<p>Penny set the table and dished up the dry breakfast
+cereal.</p>
+<p>&ldquo;At least we have beautiful scenery,&rdquo; she remarked
+as she sat down to the dismal repast with her father.
+&ldquo;Just look at those grand old trees.&rdquo;</p>
+<div class="pb" id="Page_44">[44]</div>
+<p>&ldquo;The place is all right. It&rsquo;s camping that has me
+tied in a knot. Now at the Crystal Inn we could
+be comfortable&mdash;right on the beach too.&rdquo;</p>
+<p>&ldquo;No,&rdquo; Penny said, though not very firmly. &ldquo;We&rsquo;ll
+like it here after we get adjusted.&rdquo;</p>
+<p>&ldquo;Need any supplies today?&rdquo; Mr. Parker asked abruptly.</p>
+<p>&ldquo;Yes, we&rsquo;ll have to have fresh meat and milk. I
+forgot salt too and bread.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll drive down to Sunset Beach and get the things.
+May as well take the stove along too and try to have
+it repaired.&rdquo;</p>
+<p>&ldquo;That might be a good idea,&rdquo; Penny admitted,
+though with reluctance. &ldquo;Don&rsquo;t be gone long, will
+you? I thought we might explore some of the trails.&rdquo;</p>
+<p>&ldquo;Oh, there&rsquo;s plenty of time for that.&rdquo;</p>
+<p>Mr. Parker was noticeably cheerful as he stowed
+the portable stove in the car and drove away. Not
+without misgiving Penny watched him go. She remained
+somewhat troubled as she washed the breakfast
+dishes at the brook and struggled with the beds.
+The camping trip hadn&rsquo;t worked out as she had hoped
+and expected. So far it had been all work and no fun.</p>
+<p>&ldquo;Dad was up to something when he skipped out
+of here so fast,&rdquo; she mused. &ldquo;Wonder why he doesn&rsquo;t
+come back?&rdquo;</p>
+<div class="pb" id="Page_45">[45]</div>
+<p>The sun rose high above the trees, drying the grass
+and tent. Penny went for a short hike in the woods.
+She returned to find that her father still had not returned.</p>
+<p>Just then a car rattled up the twisting road. Recognizing
+the same ranger who had caused so much
+trouble the previous night, Penny prepared herself
+for further blows. However, the government man
+was all smiles as he pulled up not far from the umbrella
+tent.</p>
+<p>&ldquo;Just dropped by to see if you&rsquo;re getting along all
+right,&rdquo; he greeted her in a friendly way. &ldquo;Everything
+Okay?&rdquo;</p>
+<p>&ldquo;I wouldn&rsquo;t venture such a rash statement as that,&rdquo;
+Penny answered, her face downcast.</p>
+<p>Because the ranger, whose name was Bill Atkins,
+seemed to have a genuine interest, she found herself
+telling him all about her troubles.</p>
+<p>&ldquo;Why, you&rsquo;ve not had a decent meal since you
+came here!&rdquo; he exclaimed, climbing out of the car.
+&ldquo;Maybe I can help you.&rdquo;</p>
+<p>&ldquo;Can you wave a magic wand and produce hot
+food?&rdquo;</p>
+<p>&ldquo;We&rsquo;ll see,&rdquo; laughed the ranger. &ldquo;Gasoline stoves
+are more bother than they&rsquo;re worth in my opinion.&rdquo;</p>
+<p>As Penny watched in amazed admiration he built
+a good fire which soon made a bed of glowing cherry
+red coals.</p>
+<div class="pb" id="Page_46">[46]</div>
+<p>&ldquo;How about a nice pan of fish fried to a crisp
+brown?&rdquo; the ranger tempted her. &ldquo;I caught a string
+of them this morning. Beauties!&rdquo;</p>
+<p>From the car he brought a basket of fat trout, already
+dressed and ready for cooking. Without asking
+Penny for anything, he wrapped them in corn
+meal, salted each fish and let it sizzle in hot butter.</p>
+<p>&ldquo;Do you always travel with your car equipped like
+a kitchen cabinet?&rdquo; Penny joked. Crouching beside
+the fire, she barely could take her eyes from the food.</p>
+<p>&ldquo;Not always,&rdquo; the ranger laughed. &ldquo;I&rsquo;ve been on
+an overnight trip. Usually have the fixings of a meal
+with me though.&rdquo;</p>
+<p>While the fish slowly sizzled, Bill put on a pot of
+coffee and fried potatoes. He accomplished everything
+with such ease that Penny could only watch
+dumbfounded.</p>
+<p>&ldquo;Guess you and your father considered me an old
+crab last night,&rdquo; he remarked. &ldquo;Sometimes we hate
+to enforce the rules, but we have to treat everyone
+alike. If we allowed folks to camp wherever they
+pleased the danger of forest fire would be greatly
+increased.&rdquo;</p>
+<p>&ldquo;You&rsquo;re right, of course. Have you had any fires
+this season?&rdquo;</p>
+<p>&ldquo;Not here.&rdquo; Deftly the ranger dished up the potatoes
+and crisply browned fish. &ldquo;Plenty of them farther
+South. Not all caused by carelessness of campers
+either.&rdquo;</p>
+<div class="pb" id="Page_47">[47]</div>
+<p>Penny was quick to seize upon the remark. &ldquo;Sabotage?&rdquo;
+she questioned.</p>
+<p>&ldquo;That&rsquo;s what we think,&rdquo; the ranger nodded. He
+poured two cups of steaming, black coffee. &ldquo;Fact is,
+enemy agents have made quite a few attempts to set
+fire to our forests. Nearly always they&rsquo;re caught,
+but that doesn&rsquo;t mean we dare let up our vigilance.&rdquo;</p>
+<p>Penny ate every morsel of the food, praising the
+ranger highly for his cooking ability.</p>
+<p>&ldquo;I wish Dad could have had some of this fish,&rdquo; she
+added. &ldquo;He went down to Sunset Beach for supplies
+and for some reason hasn&rsquo;t returned.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll have to be on the road myself,&rdquo; the ranger declared,
+getting up from the ground. &ldquo;I&rsquo;m due in town
+at twelve o&rsquo;clock and it&rsquo;s nearly that now.&rdquo;</p>
+<p>&ldquo;You&rsquo;re driving to Sunset Beach?&rdquo;</p>
+<p>&ldquo;Yes, want to ride along?&rdquo;</p>
+<p>Penny debated briefly. &ldquo;Wait until I get my coat,&rdquo;
+she requested. &ldquo;It&rsquo;s lonesome here alone. Anyway,
+I want to learn what&rsquo;s keeping Dad.&rdquo;</p>
+<p>The park road had dried considerably, but even so
+the car skidded from side to side until it reached the
+paved highway. At Sunset Beach, the ranger dropped
+Penny off at the postoffice. Rather at a loss to know
+what to do with herself, she wandered about the half-deserted
+streets in search of her father. He was not
+at any of the stores, nor did inquiry reveal his whereabouts.</p>
+<div class="pb" id="Page_48">[48]</div>
+<p>&ldquo;Perhaps he&rsquo;s sunning himself on the beach,&rdquo; she
+thought.</p>
+<p>A boardwalk led over the dunes to the water front.
+The tide was at ebb, revealing a long, wide stretch
+of white sand strewn with shells and seaweed. Penny
+paused to gaze meditatively upon the wind-swept sea.
+For a time she watched the waves break and spill their
+foam on the sandy shore. Then she walked slowly
+on toward the imposing Crystal Inn.</p>
+<p>Approaching the private beach area, Penny met
+only a few persons, mostly soldiers on furlough with
+their girls. There were no bathers for a sharp, cool
+wind blew off the water.</p>
+<p>&ldquo;Sunset Beach is nice,&rdquo; thought Penny, &ldquo;but it&rsquo;s
+lonesome.&rdquo;</p>
+<p>At the Crystal Inn there was more activity. Tennis
+courts were in use and so was the swimming pool.
+Penny circled the well-kept grounds, not intending
+to enter the building. However, as she drew near,
+her attention was drawn to the flagstone terrace overlooking
+the formal garden. Though it was set with
+tables there were not many diners.</p>
+<p>Suddenly Penny stopped short, scarcely believing
+her eyes. At one of the tables near the stone railing
+sat her father with Mrs. Deline.</p>
+<div class="pb" id="Page_49">[49]</div>
+<h2 id="c7"><span class="small">CHAPTER</span>
+<br /><span class="large">7</span>
+<br /><i>THE BEARDED STRANGER</i></h2>
+<p>Penny&rsquo;s first thought upon seeing her father
+and Mrs. Deline was to steal quietly away. Then
+amazement and injury gave way to a feeling of indignation.
+Perhaps her father had a perfect right to
+lunch with Mrs. Deline, but it was inconsiderate of
+him to so completely forget his own daughter.</p>
+<p>&ldquo;I might just as well be an orphan!&rdquo; Penny sighed.
+&ldquo;Well, we&rsquo;ll see!&rdquo;</p>
+<p>Stiffly she marched across the lawn to the railed-in
+hotel veranda. Her father saw her coming. His look
+of surprise changed to one of guarded welcome.</p>
+<p>&ldquo;Come up and have lunch with us,&rdquo; he invited.
+&ldquo;The food here is quite an improvement on what
+we&rsquo;ve been having at camp.&rdquo;</p>
+<p>Penny could find no outside entranceway to the
+terrace. To Mrs. Deline&rsquo;s horror and her father&rsquo;s
+amusement, she climbed over the stone railing.</p>
+<div class="pb" id="Page_50">[50]</div>
+<p>&ldquo;Dad,&rdquo; Penny began, ignoring the widow except
+for a curt nod, &ldquo;I was just about ready to get out a
+search warrant for you.&rdquo;</p>
+<p>Mr. Parker drew another chair to the table for his
+daughter. Her hair was none too well combed, she
+wore no stockings, and the coat did not entirely cover
+her camp costume. By contrast Mrs. Deline was perfectly
+turned out in tailored tweed suit with a smart
+little hat of feathers. Though the woman said nothing,
+her gaze was scornful as she appraised Penny.</p>
+<p>&ldquo;What shall I order for you?&rdquo; Mr. Parker asked,
+signaling a waiter.</p>
+<p>&ldquo;Nothing, thank you.&rdquo; Penny was coldly polite.
+&ldquo;I had a very fine lunch at camp, thanks to one of the
+rangers.&rdquo;</p>
+<p>&ldquo;I&rsquo;m sorry I didn&rsquo;t get back,&rdquo; Mr. Parker apologized.
+&ldquo;It took a long while to have the stove repaired.
+Then I met Mrs. Deline and&mdash;&rdquo;</p>
+<p>&ldquo;Oh, I understand,&rdquo; Penny broke in. &ldquo;The point
+is, when, if ever, are you coming back to camp?&rdquo;</p>
+<p>&ldquo;Why, right now I suppose. We&rsquo;ve finished our
+luncheon.&rdquo;</p>
+<p>The waiter had come to the table. Mr. Parker
+asked for the bill, paid it, and arose. As he bade Mrs.
+Deline goodbye, he remarked that he probably would
+see her again soon.</p>
+<div class="pb" id="Page_51">[51]</div>
+<p>Walking to the hotel parking lot where Mr. Parker
+had left the car, neither he nor Penny had much to
+say. Not until they were driving through the village
+was the subject of Mrs. Deline mentioned.</p>
+<p>&ldquo;I don&rsquo;t see why you can&rsquo;t be a bit nicer to her,&rdquo;
+Mr. Parker commented. &ldquo;You scarcely spoke a word
+to her.&rdquo;</p>
+<p>&ldquo;Did she say anything to me?&rdquo;</p>
+<p>&ldquo;Well, I don&rsquo;t recall.&rdquo;</p>
+<p>&ldquo;I&rsquo;ve treated Mrs. Deline just as well as she treats
+me!&rdquo; Penny defended herself. &ldquo;I&rsquo;ll admit I don&rsquo;t like
+her.&rdquo;</p>
+<p>&ldquo;And you show it too.&rdquo;</p>
+<p>&ldquo;Maybe I do, but she has no business taking so
+much of your time.&rdquo;</p>
+<p>&ldquo;So that&rsquo;s where the shoe pinches,&rdquo; chuckled Mr.
+Parker. &ldquo;My little girl is jealous.&rdquo;</p>
+<p>&ldquo;The very idea!&rdquo;</p>
+<p>&ldquo;Mrs. Deline is brilliant&mdash;a highly educated woman
+and I enjoy talking to her,&rdquo; Mr. Parker said thoughtfully.
+&ldquo;I assure you it&rsquo;s no more serious than that.&rdquo;</p>
+<p>Penny moved close to her father and squeezed his
+arm.</p>
+<p>&ldquo;We&rsquo;ve been pals for such a long while,&rdquo; she said
+wistfully. &ldquo;If anything ever should come between
+us&mdash;&rdquo;</p>
+<p>&ldquo;Penny, you&rsquo;re positively morbid!&rdquo; her father interrupted.
+&ldquo;Of course nothing ever will come between
+us! Now let&rsquo;s talk of more cheerful subjects.&rdquo;</p>
+<div class="pb" id="Page_52">[52]</div>
+<p>&ldquo;Such as?&rdquo;</p>
+<p>&ldquo;I&rsquo;ve been thinking, Penny. You need a friend,
+someone to pal around with.&rdquo;</p>
+<p>&ldquo;You&rsquo;re the only friend I need, Dad.&rdquo;</p>
+<p>&ldquo;I mean someone your own age, Penny. Why not
+send for Louise Sidell? I&rsquo;ll gladly pay her train fare.&rdquo;</p>
+<p>&ldquo;It would be fun having Lou here.&rdquo;</p>
+<p>&ldquo;Then it&rsquo;s settled. We&rsquo;ll send a wire now.&rdquo; Mr.
+Parker turned the car around and drove to the local
+telegraph office.</p>
+<p>Before Penny could change her mind, the message
+was sent. Not until long after she and her father had
+returned to the park did it occur to her that unwittingly
+she might have fashioned her own undoing.
+Though camping would be far more interesting with
+Louise to share her experiences, it also would give her
+father added opportunity to see Mrs. Deline.</p>
+<p>&ldquo;Maybe he didn&rsquo;t think of that angle,&rdquo; Penny reflected
+uneasily. &ldquo;I&rsquo;ll keep it to myself.&rdquo;</p>
+<p>The following day Mr. Parker spent the entire day
+in camp. With the gasoline stove in working order,
+hot meals were prepared though not without endless
+effort. There were dishes to wash, beds to make, and
+by the time the tasks were done, neither Penny nor
+her father had any energy left for hiking.</p>
+<div class="pb" id="Page_53">[53]</div>
+<p>The second day was much easier. However, with
+more free time, Mr. Parker became increasingly restless.
+He missed his morning paper and was dissatisfied
+with the skimpy news reports that came in over
+the radio. Penny was not surprised when he mentioned
+that he would walk down to Sunset Beach.</p>
+<p>&ldquo;Mind if I go with you?&rdquo; Penny asked quickly.</p>
+<p>&ldquo;Of course not,&rdquo; her father answered. &ldquo;Why
+should I?&rdquo;</p>
+<p>At Sunset Beach a call at the local telegraph office
+disclosed a message for Penny which had been held
+for lack of an address. The wire was from Louise
+and read:</p>
+<p>&ldquo;ARRIVING AT SUNSET BEACH THURSDAY
+ON THE 12:30 PLANE. HOLD EVERYTHING.&rdquo;</p>
+<p>&ldquo;Thursday!&rdquo; Penny cried, offering the telegram to
+her father. &ldquo;That&rsquo;s tomorrow! My, will I be glad
+to see Lou! This place has been like a morgue without
+her.&rdquo;</p>
+<p>&ldquo;I imagine the town will brighten up quite a bit
+within the next few days,&rdquo; Mr. Parker said, a twinkle
+in his eye. &ldquo;In fact, Louise may not be the only new
+arrival.&rdquo;</p>
+<p>&ldquo;Is someone else coming to see us?&rdquo;</p>
+<p>Mr. Parker would not answer her many questions.
+&ldquo;Wait and see,&rdquo; he teased.</p>
+<p>Since arriving at Sunset Beach Penny had been
+eager to visit the lighthouse located on Crag Point.
+Noticing that the tide was low, she suggested to her
+father that they go there together.</p>
+<div class="pb" id="Page_54">[54]</div>
+<p>&ldquo;Too long a walk,&rdquo; he complained. &ldquo;You run along
+by yourself. I&rsquo;ll sun myself on the beach.&rdquo;</p>
+<p>Leaving her father, Penny started off alone. The
+sun was warm and there were a number of bathers
+splashing about in the surf. A long row of picturesque
+cottages lined the water front. They thinned
+out as she went farther up the beach, and presently
+there were no habitations, only desolate, wind-blown
+sand.</p>
+<p>Midway to the lighthouse, Penny met a man of
+early middle age who carried fishing rod and creel.
+He stared at her, hesitated, then paused to speak.</p>
+<p>&ldquo;I notice you&rsquo;re going toward Crag Point,&rdquo; he remarked
+pleasantly. &ldquo;Are you a stranger to this locality?&rdquo;</p>
+<p>Penny admitted that she was.</p>
+<p>&ldquo;Then perhaps you haven&rsquo;t been told that the Point
+is a dangerous place to be at high tide.&rdquo;</p>
+<p>&ldquo;No, I hadn&rsquo;t heard.&rdquo;</p>
+<p>&ldquo;The Point is very nearly covered at that time,&rdquo;
+the stranger explained. &ldquo;There&rsquo;s no danger at the
+present moment, of course.&rdquo;</p>
+<p>&ldquo;How long will I have here?&rdquo;</p>
+<p>&ldquo;Oh, several hours,&rdquo; the stranger replied. &ldquo;There&rsquo;s
+no cause for alarm if you just keep watch of the
+tide.&rdquo;</p>
+<div class="pb" id="Page_55">[55]</div>
+<p>Penny thanked the stranger and walked on toward
+the lighthouse. The structure rose to a height of
+seventy-five feet above the beach and was reached by
+means of a narrow little iron stairway.</p>
+<p>No one was about the premises as Penny approached.
+However, as she started up the iron steps,
+a door far above her head opened. A burly, stout
+man whose face was browned by wind and sun,
+peered down at her.</p>
+<p>&ldquo;You can&rsquo;t come up here!&rdquo; he shouted. &ldquo;No visitors
+are allowed!&rdquo;</p>
+<p>&ldquo;Oh,&rdquo; Penny murmured, retreating a step. &ldquo;I
+didn&rsquo;t know. I only wanted to see the tower.&rdquo;</p>
+<p>&ldquo;No visitors,&rdquo; the keeper of the light repeated.
+&ldquo;War regulations.&rdquo;</p>
+<p>The rule seemed a reasonable one, but after such
+a long hike, Penny was disappointed. Walking back
+to the main section of the beach, she looked about
+for her father. He had disappeared.</p>
+<p>&ldquo;I&rsquo;ll bet a cookie he&rsquo;s at the Crystal Inn!&rdquo; she
+thought indignantly.</p>
+<p>But Penny could not find her father there nor at
+any other place along the water front. After an
+hour&rsquo;s search she decided that he must have returned
+to camp. Returning there, she approached the tent,
+noticing that the flap was closed, though not buttoned
+as she had left it.</p>
+<p>&ldquo;Dad must be here,&rdquo; she thought.</p>
+<p>Drawing nearer she could see movement within the
+tent as someone brushed against the canvas walls.</p>
+<div class="pb" id="Page_56">[56]</div>
+<p>&ldquo;Oh, Dad!&rdquo; she called.</p>
+<p>There was no answer. But the next instant a man
+in rough garments and straw hat rushed out of the
+tent. Penny never before had set eyes upon him.
+She was so astonished that she gained only a fleeting
+impression of the bearded stranger. Seeing her, he
+thrust some object beneath his coat and fled into the
+woods.</p>
+<div class="pb" id="Page_57">[57]</div>
+<h2 id="c8"><span class="small">CHAPTER</span>
+<br /><span class="large">8</span>
+<br /><i>KEEPER OF THE LIGHT</i></h2>
+<p>Recovering from astonishment, Penny darted
+to the tent and jerked open the flap. The beds had
+been torn apart. Her purse, hidden beneath the pillow,
+was gone. Suitcases lay open on the canvas
+floor.</p>
+<p>&ldquo;That man was a thief!&rdquo; she thought angrily.</p>
+<p>Too late, she tried to determine which direction he
+had taken. She could hear no sound of crackling
+leaves or running feet.</p>
+<p>&ldquo;He&rsquo;s lying low,&rdquo; she told herself. &ldquo;No use chasing
+him. I never could find him among the trees.&rdquo;</p>
+<p>Thoroughly incensed, she went back to the disordered
+tent. A preliminary check revealed that besides
+the pocketbook, a pair of her father&rsquo;s shoes and
+a sweater had been taken.</p>
+<p>&ldquo;Lucky I didn&rsquo;t have much money in my purse,&rdquo;
+Penny congratulated herself. &ldquo;It was a good leather
+pocketbook though, and I hate to lose it.&rdquo;</p>
+<div class="pb" id="Page_58">[58]</div>
+<p>Going outside, she discovered other losses. The
+supply of groceries had been ransacked. Bread was
+gone, several oranges and a tin of cold meat.</p>
+<p>&ldquo;That fellow was hungry,&rdquo; Penny reflected.
+&ldquo;Probably some shiftless person who isn&rsquo;t willing to
+work for a living.&rdquo;</p>
+<p>Entering the tent again, she busied herself making
+the beds and repacking the suitcases. As she finished
+the task, she heard footsteps outside. Fearful that
+the thief had returned, she jerked open the canvas
+flap. It was her father who had arrived.</p>
+<p>&ldquo;Oh, Dad, I&rsquo;m glad you&rsquo;re back!&rdquo; she exclaimed,
+rushing out to meet him. &ldquo;We&rsquo;ve been robbed!&rdquo;</p>
+<p>&ldquo;What?&rdquo;</p>
+<p>Penny told him how she had frightened away the
+bearded stranger.</p>
+<p>&ldquo;That&rsquo;s bad,&rdquo; Mr. Parker said, frowning. &ldquo;I didn&rsquo;t
+suppose there was another camper within miles of us.&rdquo;</p>
+<p>&ldquo;This man didn&rsquo;t look like a camper, Dad. He
+wore dirty, mussed clothing and a beard of at least
+a week&rsquo;s growth.&rdquo;</p>
+<p>&ldquo;How old a fellow?&rdquo;</p>
+<p>&ldquo;Why, he looked young to me. And he ran like
+a young person.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll report it to the ranger,&rdquo; Mr. Parker said,
+entering the tent to check over his belongings.
+&ldquo;Probably never will get any of our things back
+though.&rdquo;</p>
+<p>&ldquo;The ranger may know who the fellow is, Dad.&rdquo;</p>
+<div class="pb" id="Page_59">[59]</div>
+<p>&ldquo;That&rsquo;s possible,&rdquo; Mr. Parker admitted. &ldquo;Penny,
+I&rsquo;m glad Louise is coming tomorrow. I certainly
+don&rsquo;t like the idea of your remaining here in camp
+alone.&rdquo;</p>
+<p>&ldquo;Then why don&rsquo;t you stay with me?&rdquo; Penny countered
+instantly.</p>
+<p>&ldquo;Well, I&rsquo;m planning on being rather busy.&rdquo;</p>
+<p>&ldquo;With Mrs. Deline.&rdquo;</p>
+<p>&ldquo;Penny, you&rsquo;re impossible!&rdquo;</p>
+<p>&ldquo;Weren&rsquo;t you with her today? I looked everywhere
+for you.&rdquo;</p>
+<p>&ldquo;Mrs. Deline and I did go for a little walk. No
+harm in that, is there?&rdquo;</p>
+<p>&ldquo;It all depends upon your viewpoint,&rdquo; Penny said
+loftily. &ldquo;Personally, I consider her about as harmless
+as a Grade A rattler!&rdquo;</p>
+<p>&ldquo;Penny, enough of such talk!&rdquo;</p>
+<p>&ldquo;Okay,&rdquo; she returned grimly, &ldquo;but never say I
+didn&rsquo;t warn you.&rdquo;</p>
+<p>&ldquo;I was about to tell you,&rdquo; Mr. Parker resumed,
+&ldquo;that I expect to be busy the next few days helping
+local authorities trace that outlaw radio station we
+heard on the air.&rdquo;</p>
+<p>&ldquo;Oh!&rdquo;</p>
+<p>&ldquo;In fact, Army experts are being sent here to aid
+in the work. My days will be pretty well tied up.&rdquo;</p>
+<p>&ldquo;I&rsquo;m sorry, Dad,&rdquo; Penny said contritely. &ldquo;Naturally
+I thought&mdash;&rdquo;</p>
+<div class="pb" id="Page_60">[60]</div>
+<p>&ldquo;I&rsquo;m afraid your trouble is that you don&rsquo;t stop to
+think,&rdquo; Mr. Parker lectured. &ldquo;Please, will you forget
+Mrs. Deline?&rdquo;</p>
+<p>&ldquo;I promise not to bother you about her again, Dad.&rdquo;</p>
+<p>&ldquo;Good!&rdquo; Mr. Parker awkwardly patted his daughter&rsquo;s
+hand. &ldquo;I realize you&rsquo;ve had an unpleasant time
+of it so far, Penny. But things should pick up after
+Louise arrives.&rdquo;</p>
+<p>&ldquo;And that other surprise you hinted about?&rdquo;</p>
+<p>&ldquo;Oh, you&rsquo;ll have to wait and see,&rdquo; Mr. Parker
+smiled. &ldquo;However, I promise you that what&rsquo;s coming
+really will prove a pleasant surprise.&rdquo;</p>
+<p>Though Penny kept up a running fire of questions,
+her father would tell her no more. From a few hints
+he dropped, she gathered that he was expecting a visitor
+within a day or so. That rather disappointed her,
+for with the exception of Louise, she could think of
+no one she particularly wanted to see at Sunset Beach.</p>
+<p>Later that day when a forest ranger stopped at
+camp for a few minutes, Mr. Parker reported the
+theft of food and clothing to him.</p>
+<p>&ldquo;So the thief was a young man with a beard?&rdquo; the
+ranger pondered. &ldquo;Don&rsquo;t know of anyone in the
+area answering such a description. We&rsquo;ll certainly be
+on the watch for him.&rdquo;</p>
+<p>Penny and her father expected to hear no more
+from the matter. Toward sundown, however, the
+same ranger returned to camp, bringing the missing
+pocketbook. It was stripped of money but still contained
+a compact and various toilet articles.</p>
+<div class="pb" id="Page_61">[61]</div>
+<p>&ldquo;Where did you find the purse?&rdquo; Penny inquired
+eagerly.</p>
+<p>&ldquo;On the Beech Trail not far from here.&rdquo;</p>
+<p>&ldquo;Then it was dropped on purpose?&rdquo;</p>
+<p>&ldquo;Apparently it was. I followed the trail for a
+quarter of mile, then lost the fellow when he took to
+the brook.&rdquo;</p>
+<p>&ldquo;Rather a smart fellow to think of that,&rdquo; commented
+Mr. Parker thoughtfully. &ldquo;Perhaps he wasn&rsquo;t
+an ordinary snatch-thief after all.&rdquo;</p>
+<p>The ranger offered no comment. As he turned
+to go, he did assure Penny again that every effort
+would be made to capture the culprit.</p>
+<p>&ldquo;If the fellow still is in the park we&rsquo;ll get him,&rdquo;
+he declared. &ldquo;Don&rsquo;t you worry about that.&rdquo;</p>
+<p>With the coming of dusk a penetrating chill settled
+over the camp. Even the hot supper of steak and
+potatoes that Penny prepared failed to sufficiently
+warm the two tenters. They did the dishes and then,
+not wishing to go to bed, sought the enclosed car for
+heat.</p>
+<p>&ldquo;It&rsquo;s starting to rain,&rdquo; Mr. Parker observed as a few
+drops splashed against the windshield. &ldquo;Looks as
+if we&rsquo;re in for another siege of it.&rdquo;</p>
+<p>&ldquo;And Louise is due tomorrow,&rdquo; Penny sighed.
+&ldquo;Unless the weather improves I&rsquo;d not blame her one
+bit if she turns right around and starts back to Riverview.&rdquo;</p>
+<div class="pb" id="Page_62">[62]</div>
+<p>The rain came down steadily with a promise of
+continuing throughout the night. Mr. Parker read a
+day-old newspaper by the light in the car, grumbling
+because the news was so old. Presently he switched
+on the radio, trying without success to tune in the
+outlaw station which had been heard previously at
+the same hour.</p>
+<p>&ldquo;No luck,&rdquo; he commented. &ldquo;Reception must be
+poor tonight, or the station has changed to another
+time. Probably it&rsquo;s shifted to a different locality too.&rdquo;</p>
+<p>&ldquo;Dad, isn&rsquo;t it true that the operator of that secret
+station is an enemy agent?&rdquo; Penny asked curiously.</p>
+<p>&ldquo;It&rsquo;s a possibility.&rdquo;</p>
+<p>&ldquo;Why not tell me all about it?&rdquo;</p>
+<p>&ldquo;Nothing to tell yet, Penny. Confidentially I&rsquo;ll
+admit I came here hoping to help State authorities
+find the station. So far I&rsquo;ve accomplished nothing.&rdquo;</p>
+<p>&ldquo;What clues have you gained?&rdquo;</p>
+<p>&ldquo;Now Penny, don&rsquo;t quiz me,&rdquo; Mr. Parker laughed.
+&ldquo;I&rsquo;ll tell you everything as soon as I&rsquo;m free to do so.&rdquo;</p>
+<p>&ldquo;In the meantime, maybe I&rsquo;ll find out for myself!&rdquo;
+Penny hinted. Abruptly swinging open the car door,
+she bolted through the rain to the tent.</p>
+<div class="pb" id="Page_63">[63]</div>
+<p>Breakfast the next morning was a more cheerful
+meal than had been expected. During the night the
+rain had ceased and a hot morning sun soon dried out
+the drenched canvas. Mr. Parker prepared coffee,
+eggs and bacon, an unbelievable example of perfect
+cooking.</p>
+<p>&ldquo;Dad, I didn&rsquo;t think you had it in you!&rdquo; Penny
+praised as she sat down on a camp stool beside him.
+&ldquo;Maybe you&rsquo;ll develop into a real camper after all.&rdquo;</p>
+<p>&ldquo;Not if I have anything to say about it.&rdquo; Grinning,
+Mr. Parker dropped two plump fried eggs on
+his daughter&rsquo;s plate and took the remaining four for
+himself. &ldquo;This life could be worse though.&rdquo;</p>
+<p>&ldquo;Dad, what time shall we start for the airport?&rdquo;</p>
+<p>Mr. Parker poured himself a cup of coffee and then
+answered: &ldquo;Afraid I won&rsquo;t be able to go with you,
+Penny.&rdquo;</p>
+<p>&ldquo;But Dad! Louise will be expecting you.&rdquo;</p>
+<p>&ldquo;It&rsquo;s not me she wants to see,&rdquo; Mr. Parker corrected.
+&ldquo;I have an important engagement I can&rsquo;t
+break.&rdquo;</p>
+<p>Penny glanced quickly up. She was tempted to
+ask her father if he intended to see Mrs. Deline. Recalling
+that she had made her father a promise, she
+wisely withheld comment. Instead she asked if she
+might use the car.</p>
+<p>&ldquo;By all means,&rdquo; he consented. &ldquo;Just go easy on the
+gasoline.&rdquo;</p>
+<p>Breakfast over, dishes were dispatched and the
+camp put in order. By eleven o&rsquo;clock Penny and her
+father were in Sunset Beach.</p>
+<div class="pb" id="Page_64">[64]</div>
+<p>&ldquo;Drop me anywhere,&rdquo; Mr. Parker instructed
+vaguely.</p>
+<p>Leaving her father on a street corner, Penny drove
+slowly toward the airport a mile and a quarter away.
+There was little travel on the winding highway which
+curled along the beach. A government jeep whizzed
+past and two soldiers shouted and waved. Penny
+waved back.</p>
+<p>There was no need to hurry for Louise&rsquo;s plane was
+not yet due. Penny took her time and enjoyed the
+ocean scenery. The tide was coming in and gulls
+free-wheeled over the waves, dipping down at intervals
+in search of food.</p>
+<p>Gazing along the deserted beach, Penny was startled
+to see a familiar feminine figure hastening toward
+the lighthouse on Crag Point. The woman wore a
+white scarf that half obscured her face, yet the girl
+easily recognized her.</p>
+<p>&ldquo;Mrs. Deline!&rdquo; she thought, idling the car. &ldquo;She&rsquo;s
+certainly going to the lighthouse! I wonder if that
+gruff old keeper will drive her away as he did me?&rdquo;</p>
+<p>Curious to learn what would happen, the girl drew
+up at the side of the road. Mrs. Deline was too far
+away to observe the automobile. Intent only upon
+her own affairs, she walked swiftly along the beach
+until she reached the base of the lighthouse.</p>
+<p>&ldquo;Now to see the fun!&rdquo; chuckled Penny.</p>
+<div class="pb" id="Page_65">[65]</div>
+<p>The keeper had appeared on the platform and was
+gazing down upon the visitor. He called something
+to the woman that Penny could not hear. But to her
+amazement, Mrs. Deline started up the iron stairway.</p>
+<p>Penny waited expectantly. She was certain that
+the keeper of the light would order Mrs. Deline away.
+Instead, he greeted her with a hearty handshake as if
+they were old friends. They entered the lighthouse
+tower room together, and the heavy door closed behind
+them.</p>
+<div class="pb" id="Page_66">[66]</div>

+<br /><i>A SURPRISE FROM THE SKY</i></h2>
+<p>&ldquo;Well, if that isn&rsquo;t strange!&rdquo; Penny muttered. &ldquo;I
+wasn&rsquo;t permitted to set foot inside the lighthouse, but
+in goes Mrs. Deline without a single question asked!&rdquo;</p>
+<p>Her curiosity aroused, the girl decided to wait and
+watch. Twenty minutes elapsed. During that time
+Mrs. Deline did not reappear. Penny grew tired of
+her vigil.</p>
+<p>&ldquo;Mrs. Deline evidently intends to stay there a long
+while,&rdquo; she thought as she drove on. &ldquo;For all I know,
+she and the lighthouse keeper may be old friends.
+They did greet each other as if they were acquainted.&rdquo;</p>
+<p>At the airport Penny parked on the crowded lot.
+She dropped into the lunch room for a sandwich and
+then wandered out on the cement runway. The noon
+passenger plane presently was announced through the
+loudspeaker system. A moment later Penny glimpsed
+the big silver twin-motor transport gliding down over
+the tree tops. As it taxied up to unload passengers,
+she held her breath. Knowing that there had been
+several last-minute cancellation of tickets, she was
+afraid that Louise might not be aboard.</p>
+<div class="pb" id="Page_67">[67]</div>
+<p>But as the door of the big transport swung back,
+her chum was the second passenger to alight. Fresh
+and trim in a yellow wool suit, she flung herself into
+Penny&rsquo;s arms.</p>
+<p>&ldquo;Have a nice trip, Lou?&rdquo;</p>
+<p>&ldquo;Oh, heavenly! Only it didn&rsquo;t last long enough.
+We were here almost before I knew we&rsquo;d started. I
+nearly lost my ticket to an Army Major too!&rdquo;</p>
+<p>&ldquo;I was afraid you might not get here,&rdquo; Penny
+laughed, picking up Louise&rsquo;s light over-night case.
+&ldquo;What happened to the Major?&rdquo;</p>
+<p>&ldquo;Oh, at the last minute he changed his mind, so the
+company decided I could have my ticket back. And
+here I am! How&rsquo;s camping?&rdquo;</p>
+<p>&ldquo;Not much fun so far,&rdquo; Penny confessed truthfully.
+&ldquo;But I can feel things starting to pick up.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll have a wonderful time together.&rdquo;</p>
+<p>&ldquo;You just bet we will!&rdquo; Penny declared with emphasis.
+&ldquo;Had anything to eat?&rdquo;</p>
+<p>&ldquo;Oh, yes, lunch was served on the plane.&rdquo;</p>
+<p>&ldquo;Then we may as well start for camp. I have
+oodles to tell you, Lou.&rdquo;</p>
+<p>Midway to the parking lot, Louise paused, calling
+attention to a Flying Fortress that was coming in
+against the wind.</p>
+<div class="pb" id="Page_68">[68]</div>
+<p>&ldquo;Let&rsquo;s watch it land,&rdquo; she pleaded. &ldquo;Did you ever
+see such a beautiful ship?&rdquo;</p>
+<p>The huge Fortress came in fast for a perfect landing.
+Crew members began to tumble out through
+the door. One of the young men in captain&rsquo;s uniform
+evidently was a passenger for he carried a suitcase.</p>
+<p>&ldquo;Lou!&rdquo; Penny grasped her chum&rsquo;s arm. &ldquo;That
+flier looks like Jerry Livingston!&rdquo;</p>
+<p>&ldquo;Oh, it couldn&rsquo;t be!&rdquo;</p>
+<p>&ldquo;All the same, I think it is!&rdquo;</p>
+<p>Penny was so excited that she barely could control
+her voice. Jerry Livingston was one of her very best
+friends, a former reporter on the <i>Riverview Star</i>. In
+the days before he had joined the Army Air Force,
+she and Jerry had shared many an exciting adventure.
+However, since he had gone away there had been
+only a few letters and those brief communications
+had contained no real news.</p>
+<p>&ldquo;It <i>is</i> Jerry!&rdquo; Penny cried an instant later. &ldquo;Oh,
+Lou, this must have been the surprise that Dad knew
+about! How could he keep it from me?&rdquo;</p>
+<p>Breaking away from her chum, Penny darted across
+the runway. As she called Jerry&rsquo;s name, the young
+man turned toward her. His handsome, wind-tanned
+face became a brilliant smile. A dozen long strides
+carried him to her side.</p>
+<div class="pb" id="Page_69">[69]</div>
+<p>&ldquo;Penny!&rdquo; he cried. He didn&rsquo;t hesitate. He just
+swept her into his arms and kissed her.</p>
+<p>&ldquo;Sorry, Penny,&rdquo; Jerry apologized, his eyes twinkling.
+&ldquo;Guess I shouldn&rsquo;t have done that. But when
+you&rsquo;ve not seen your one and only girl for going on
+a year&mdash;&rdquo;</p>
+<p>&ldquo;Your which?&rdquo; Penny stammered, too confused to
+blush.</p>
+<p>&ldquo;You are my one and only, you know,&rdquo; Jerry
+grinned. &ldquo;Always were for that matter. Even in the
+days when we tracked down news stories together.&rdquo;</p>
+<p>Louise came hurrying up. Jerry turned to greet
+her and the conversation became less personal. But
+from the way Louise smiled, Penny knew she had seen
+the kiss and would demand lengthy explanations
+later on.</p>
+<p>&ldquo;Jerry!&rdquo; she cried, noticing the decorations on his
+trim uniform. &ldquo;They&rsquo;ve given you the Distinguished
+Flying Cross! And the Purple Heart! You didn&rsquo;t
+write a word about that.&rdquo;</p>
+<p>&ldquo;Nothing to write.&rdquo;</p>
+<p>Indignantly, the girls pried the story from Jerry.
+He had piloted a Flying Fortress in a highly successful
+raid over the Romanian oil fields. To reach its
+target, the Fortress had flown through flaming refineries,
+so low to the ground that fire actually had
+leaped up through the bomb bay of the plane.
+Swarms of enemy fighter ships had been fought off.
+Jerry&rsquo;s plane was one of the few to get back to its
+base safely.</p>
+<div class="pb" id="Page_70">[70]</div>
+<p>&ldquo;I was luckier than some of the other fellows,&rdquo;
+Jerry said modestly. &ldquo;That was all. Now they&rsquo;ve
+sent me home to rest up for a while.&rdquo;</p>
+<p>&ldquo;Oh, that&rsquo;s marvelous!&rdquo; Penny said, guiding him toward
+the waiting car. &ldquo;You can spend all of your
+spare time with us!&rdquo;</p>
+<p>Jerry grinned down at her. &ldquo;I&rsquo;d like nothing better.
+But I&rsquo;m not exactly on furlough.&rdquo;</p>
+<p>&ldquo;I thought you just said&mdash;&rdquo;</p>
+<p>&ldquo;I&rsquo;m doing a special mission here at Sunset Beach
+for the Army.&rdquo;</p>
+<p>&ldquo;Anything you dare tell about?&rdquo;</p>
+<p>Jerry helped the girls into the car, stowed the suitcases
+away, and then slid in beside Penny.</p>
+<p>&ldquo;I can&rsquo;t tell you very much,&rdquo; he replied quietly.
+&ldquo;But I can give you a general idea of why I&rsquo;m here.
+There&rsquo;s a certain outlaw radio station that has been
+causing the government considerable annoyance. I&rsquo;ve
+been sent here to try to trace its location.&rdquo;</p>
+<p>&ldquo;And that&rsquo;s why Dad&rsquo;s here too!&rdquo; Penny cried.
+&ldquo;So you two schemers intended to join forces all
+along! A pity no one could let me know!&rdquo;</p>
+<div class="pb" id="Page_71">[71]</div>
+<p>&ldquo;I didn&rsquo;t want your father to tell you, because until
+the last minute I wasn&rsquo;t sure I was coming,&rdquo; Jerry
+explained. &ldquo;The radio station assignment is only part
+of the reason why I&rsquo;m here.&rdquo;</p>
+<p>&ldquo;What&rsquo;s the other?&rdquo; Penny asked as she started the
+car.</p>
+<p>&ldquo;I&rsquo;m on the lookout for an escaped German flier.
+The fellow escaped from a Canadian prison camp and
+was traced to this locality.&rdquo;</p>
+<p>&ldquo;And you&rsquo;re supposed to be taking a rest from
+flying!&rdquo;</p>
+<p>&ldquo;This assignment will be a vacation.&rdquo;</p>
+<p>&ldquo;I&rsquo;d call it anything but one,&rdquo; Penny said indignantly.
+Her face suddenly became grave.
+&ldquo;Jerry!&rdquo;</p>
+<p>&ldquo;Yes?&rdquo;</p>
+<p>&ldquo;What does that escaped prisoner look like?&rdquo;</p>
+<p>&ldquo;Oh, I can&rsquo;t describe him. I have a photograph in
+my brief case. Why do you ask?&rdquo;</p>
+<p>&ldquo;Maybe I&rsquo;ve seen him.&rdquo;</p>
+<p>&ldquo;Where?&rdquo; Jerry could not hide a smile.</p>
+<p>&ldquo;Why at our camp in the woods!&rdquo; Excitedly
+Penny told of the bearded stranger who had robbed
+the Parker stores of food and clothing. Her description
+of the man was so vague that Jerry could make
+little of it.</p>
+<p>&ldquo;I&rsquo;m afraid your thief isn&rsquo;t the man we&rsquo;re after,&rdquo;
+he said kindly. &ldquo;After I get to a hotel and open my
+luggage, I&rsquo;ll show you his picture.&rdquo;</p>
+<div class="pb" id="Page_72">[72]</div>
+<p>&ldquo;And will you let me help you trail him?&rdquo;</p>
+<p>&ldquo;Oh, sure,&rdquo; Jerry answered, only half meaning it.
+&ldquo;By the way, drive me to the Crystal Inn. I have a
+reservation there.&rdquo;</p>
+<p>Penny&rsquo;s face fell.</p>
+<p>&ldquo;Anything wrong with the place?&rdquo; Jerry inquired,
+observing her change of expression.</p>
+<p>Penny shook her head. &ldquo;The place is all right. It&rsquo;s
+the people who stay there. Jerry&mdash;&rdquo;</p>
+<p>&ldquo;Yes?&rdquo;</p>
+<p>&ldquo;Are you susceptible to brunettes?&rdquo;</p>
+<p>&ldquo;Never noticed it.&rdquo;</p>
+<p>&ldquo;You&rsquo;ll likely meet a Mrs. Deline at the hotel,&rdquo;
+Penny warned. &ldquo;Don&rsquo;t have a thing to do with
+her.&rdquo;</p>
+<p>&ldquo;Why should I?&rdquo; Jerry was amused.</p>
+<p>&ldquo;She&rsquo;s already made a jelly fish of Dad,&rdquo; Penny
+went on. &ldquo;Jerry, stop grinning! This is serious.&rdquo;</p>
+<p>&ldquo;Sorry, I didn&rsquo;t know I was smiling.&rdquo;</p>
+<p>&ldquo;I need your help, Jerry. The truth is, I&rsquo;m terribly
+worried about Dad.&rdquo;</p>
+<p>&ldquo;If I know your father, there&rsquo;s no need to worry
+about him.&rdquo;</p>
+<p>&ldquo;But you don&rsquo;t understand this Mrs. Deline,&rdquo;
+Penny said desperately. &ldquo;She&rsquo;s a very clever, scheming
+woman. Jerry, will you promise to help me try
+to save Dad from her clutches?&rdquo;</p>
+<div class="pb" id="Page_73">[73]</div>
+<p>Jerry managed to keep his face straight. &ldquo;I&rsquo;ll do
+my best,&rdquo; he promised.</p>
+<p>Penny drew a deep sigh. &ldquo;Oh, I&rsquo;m so glad you&rsquo;re
+here,&rdquo; she murmured gratefully. &ldquo;With you fighting
+on my side, the war&rsquo;s as good as won!&rdquo;</p>
+<div class="pb" id="Page_74">[74]</div>
+<h2 id="c10"><span class="small">CHAPTER</span>
+<br /><span class="large">10</span>
+<br /><i>HELP FROM MR. EMORY</i></h2>
+<p>With Jerry at Sunset Beach, the vacation already
+promised to take on a rosy hue. Penny was so
+thrilled to be with her friends again that she paid scant
+heed to her driving. Several times, enroute to the
+Crystal Inn, Louise had to warn her to steer more
+carefully.</p>
+<p>&ldquo;Oh, Jerry, now that you&rsquo;re here the fun will
+start!&rdquo; Penny declared happily. &ldquo;You&rsquo;ve no idea how
+dull things have been without you.&rdquo;</p>
+<p>&ldquo;And that goes double,&rdquo; Jerry said with emphasis.
+&ldquo;How&rsquo;s your father?&rdquo;</p>
+<p>&ldquo;Oh, fine!&rdquo; Penny laughed. &ldquo;Camping has made
+him cross though. By the way, did he know you
+were coming?&rdquo;</p>
+<p>&ldquo;Yes, I sent him a wire.&rdquo;</p>
+<p>&ldquo;I thought so! Dad&rsquo;s been keeping it from me.
+Why all the secrecy, I wonder?&rdquo;</p>
+<div class="pb" id="Page_75">[75]</div>
+<p>&ldquo;Well, my trip here isn&rsquo;t exactly a pleasure jaunt.
+And if I have luck, I&rsquo;ll be gone again in a few days.&rdquo;</p>
+<p>&ldquo;I certainly hope you have no luck then,&rdquo; Penny
+said with a laugh.</p>
+<p>The car drew up at the Crystal Inn and Jerry
+unloaded his suitcase. He was taller, Penny thought,
+or at least more filled out. The trim uniform set off
+his broad shoulders. As he bent to pick up his luggage,
+a group of women on the hotel veranda turned
+to stare at him.</p>
+<p>&ldquo;I&rsquo;ll check in and clean up a bit,&rdquo; Jerry said.
+&ldquo;Then where can I meet you girls?&rdquo;</p>
+<p>&ldquo;Oh, we&rsquo;ll be somewhere on the beach,&rdquo; Penny replied
+carelessly. &ldquo;Do hurry, Jerry. We have a million
+things to talk over.&rdquo;</p>
+<p>The girls parked the car not far from the hotel. As
+they walked along, scuffing their shoes in the loose
+sand, they saw Mrs. Deline coming toward them from
+the direction of Crag Point.</p>
+<p>&ldquo;She&rsquo;s evidently been at the lighthouse all this
+time!&rdquo; Penny commented in an undertone. &ldquo;Now
+how did she get in there for a visit when I couldn&rsquo;t?&rdquo;</p>
+<p>Mrs. Deline saw that she would meet the girls.
+Frowning, she glanced quickly toward the boardwalk
+as if seeking an avenue of escape. However, she
+could not avoid meeting them without appearing to
+do so deliberately.</p>
+<p>&ldquo;How do you do,&rdquo; she greeted Penny coldly.</p>
+<div class="pb" id="Page_76">[76]</div>
+<p>Penny paused to introduce Louise. Mrs. Deline
+acknowledged the girl with an indifferent nod.
+Somewhat confused, Louise nervously twisted a silver
+ring she wore. It slipped from her finger and fell
+into the loose sand.</p>
+<p>&ldquo;Oh, how awkward of me!&rdquo; she exclaimed, and
+stooped to retrieve it.</p>
+<p>The ring buried itself deeper in the sand.</p>
+<p>&ldquo;You&rsquo;ll lose it entirely if you&rsquo;re not careful!&rdquo;
+Penny warned. &ldquo;Here, let me help you.&rdquo;</p>
+<p>Getting down on their knees, the girls sifted the
+sand with their hands. Mrs. Deline seemed amused
+by their difficulties and did not offer to help.</p>
+<p>&ldquo;Well, I must be getting on to the hotel,&rdquo; she said
+casually. &ldquo;I took a long walk this afternoon and I&rsquo;m
+tired.&rdquo;</p>
+<p>&ldquo;To the lighthouse?&rdquo; Penny commented, before
+she stopped to think.</p>
+<p>Mrs. Deline glanced at her sharply. &ldquo;No, not to
+the lighthouse,&rdquo; she replied in a tone meant to put
+the girl in her place. &ldquo;I shouldn&rsquo;t think of walking
+that far.&rdquo;</p>
+<p>&ldquo;But I thought I saw you there.&rdquo;</p>
+<p>&ldquo;You saw me?&rdquo; Mrs. Deline laughed. &ldquo;Well, my
+dear, you certainly were mistaken. I walked to the
+12th Street bridge. No farther.&rdquo;</p>
+<div class="pb" id="Page_77">[77]</div>
+<p>Penny started to reply, then thought better of it.
+There was no point in arguing with Mrs. Deline.
+However, she was certain she had seen the widow
+at the lighthouse. Why the woman should deny it
+she could not imagine.</p>
+<p>After Mrs. Deline had gone, Penny and Louise
+searched in vain for the missing ring. They knew
+it could not be many inches away, yet it kept eluding
+them.</p>
+<p>&ldquo;Oh, I can&rsquo;t afford to lose the ring!&rdquo; Louise wailed.</p>
+<p>&ldquo;How valuable is it?&rdquo;</p>
+<p>&ldquo;It&rsquo;s not worth much from a money standpoint. I
+drew it as a prize in a piece of wedding cake and I&rsquo;ve
+always kept it as a good luck piece.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll find it,&rdquo; Penny said confidently. &ldquo;That is,
+if the tide doesn&rsquo;t catch us first.&rdquo;</p>
+<p>Just as she spoke, a wave came rippling up the
+beach. It broke only a few feet away, showering the
+girls with spray and wetting their shoes.</p>
+<p>&ldquo;If the tide flows over this spot, I never will find the
+ring,&rdquo; Louise cried in vexation. &ldquo;Such wretched
+luck!&rdquo;</p>
+<p>&ldquo;Having trouble?&rdquo; inquired a deep masculine voice.</p>
+<p>Penny and Louise raised their heads. Unnoticed
+by them, a stranger had approached. The man wore
+a wet bathing suit plastered with sand. He had on
+glasses and a moment elapsed before Penny recognized
+him as the same fisherman who had warned her
+about the tide at Crag Point.</p>
+<div class="pb" id="Page_78">[78]</div>
+<p>&ldquo;I&rsquo;m George Emory,&rdquo; he introduced himself.
+&ldquo;Have you lost something?&rdquo;</p>
+<p>&ldquo;My ring,&rdquo; Louise explained.</p>
+<p>The man helped the girls search for the missing
+trinket. By now waves were creeping higher and
+higher on the beach. A particularly big one sent
+Penny and Louise scurrying for safety.</p>
+<p>&ldquo;It&rsquo;s no use looking any longer for the ring,&rdquo;
+Louise gave up. &ldquo;Perhaps I can find it after the tide
+turns.&rdquo;</p>
+<p>&ldquo;By then it will be washed away,&rdquo; replied Mr.
+Emory. &ldquo;Ah! What&rsquo;s this?&rdquo;</p>
+<p>He stooped to pick a shiny object from the sand.</p>
+<p>&ldquo;It&rsquo;s my ring!&rdquo; Louise cried in delight. &ldquo;Oh, thank
+you for finding it!&rdquo;</p>
+<p>The three retreated to higher ground. As Penny
+and Louise were about to start for the hotel, Mr.
+Emory suggested that they might like to share a picnic
+lunch with him. Neither of the girls was hungry, but
+to offend the man after he had found Louise&rsquo;s ring
+was unthinkable. Accordingly, they accompanied
+him to one of the gaily painted wooden umbrellas
+along the beach. Beneath its shade Mr. Emory spread
+a paper tablecloth and produced ample supplies of
+sandwiches, fruit and lemonade.</p>
+<p>&ldquo;Were you expecting to eat all this food yourself?&rdquo;
+Penny asked in amazement.</p>
+<div class="pb" id="Page_79">[79]</div>
+<p>&ldquo;No, I was hoping to find a companion who would
+share it,&rdquo; replied Mr. Emory. &ldquo;The truth is, I&rsquo;m a
+pretty lonely old fellow.&rdquo;</p>
+<p>Penny and Louise stole a quick look at the stranger.
+By no stretch of the imagination could they call him
+old. Judging from appearances, he was not yet forty
+years old.</p>
+<p>&ldquo;My wife died a few years ago,&rdquo; Mr. Emory explained
+sadly. &ldquo;Since then I&rsquo;ve been like a ship without
+a rudder. I have plenty of money, but I don&rsquo;t get
+much enjoyment out of life. I go wherever it suits
+my fancy, stay until I weary of it, then move on.&rdquo;</p>
+<p>&ldquo;Oh, I see,&rdquo; Penny murmured with a show of sympathy.</p>
+<p>She felt ashamed of herself that the story did not
+move her more deeply. Mr. Emory evidently was a
+lonely fellow, deserving of companionship. Yet for
+some reason, he failed to interest her.</p>
+<p>&ldquo;Have you been at Sunset Beach long?&rdquo; she inquired
+politely.</p>
+<p>&ldquo;Oh, about a month. I know every nook and
+cranny along the shore.&rdquo;</p>
+<p>&ldquo;You do?&rdquo; Penny asked, and her interest revived.
+&ldquo;Are there many caves near Sunset Beach?&rdquo;</p>
+<p>&ldquo;Plenty of them, though none very close. There
+are several near the lighthouse, back among the rocks.
+Crystal Cave probably is the most interesting. Then
+there are half a dozen scattered on up the shore.
+Interested in caves?&rdquo;</p>
+<div class="pb" id="Page_80">[80]</div>
+<p>&ldquo;Oh, in a general way,&rdquo; Penny replied carelessly.</p>
+<p>&ldquo;Penny is interested in anything that suggests mystery,&rdquo;
+Louise volunteered with a grin.</p>
+<p>&ldquo;Mystery?&rdquo;</p>
+<p>&ldquo;Lou&rsquo;s joking,&rdquo; Penny said quickly. She gave her
+chum a hard look which was not lost upon Mr.
+Emory.</p>
+<p>&ldquo;Why, Penny!&rdquo; Louise refused to be silenced.
+&ldquo;Only a few minutes ago you were telling me about
+a radio broadcast said to come from a cave!&rdquo;</p>
+<p>&ldquo;That was just my idea,&rdquo; Penny said, confused.
+She jumped hastily to her feet. &ldquo;We really should
+be going, Lou.&rdquo;</p>
+<p>&ldquo;Oh, don&rsquo;t hurry away.&rdquo; Mr. Emory offered Louise
+another sandwich. &ldquo;Speaking of mysterious radio
+stations, I&rsquo;ve heard of one that is said to be located in a
+cave somewhere along these shores. Fact is, I&rsquo;ve
+searched for it.&rdquo;</p>
+<p>&ldquo;You have?&rdquo; Penny asked, sinking back into the
+sand. &ldquo;Any luck?&rdquo;</p>
+<p>&ldquo;None. But I did manage to kill quite a few afternoons.
+I take it that your father came to Sunset
+Beach to help the authorities search for the station.
+Right?&rdquo;</p>
+<p>&ldquo;Why, whatever made you think that?&rdquo; Penny
+asked, instantly on guard. &ldquo;Do you know my
+father?&rdquo;</p>
+<div class="pb" id="Page_81">[81]</div>
+<p>&ldquo;I regret I haven&rsquo;t the honor. I chanced to overhear
+a conversation at the hotel.&rdquo;</p>
+<p>&ldquo;Oh,&rdquo; Penny murmured. She was certain that the
+information could have leaked out in only one way.
+Her father had told Mrs. Deline, who in turn had
+spread the news about the hotel.</p>
+<p>&ldquo;I trust I&rsquo;m not inquiring into secrets,&rdquo; Mr. Emory
+went on cheerfully. &ldquo;Fact of the matter is, I might
+be able to help your father.&rdquo;</p>
+<p>&ldquo;I&rsquo;m sure Dad will want to talk with you.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll look forward to meeting your father. Think
+you can arrange it?&rdquo;</p>
+<p>&ldquo;Why, I suppose so,&rdquo; Penny said, though with no
+great enthusiasm. Again she experienced a queer,
+uneasy feeling. She did not entirely trust Mr. Emory.</p>
+<p>The man smiled and seemed to relax. As the girls
+arose to leave he tried once more to detain them.</p>
+<p>&ldquo;See that old fellow down the beach?&rdquo; he inquired,
+pointing to an aged man who was picking up objects
+from the sand with a sharp-pointed stick.</p>
+<p>&ldquo;Yes, what about him?&rdquo; Penny asked, turning to
+stare. &ldquo;Just an ordinary beachcomber, isn&rsquo;t he?&rdquo;</p>
+<p>&ldquo;I&rsquo;d not call Old Jake Skagway ordinary,&rdquo; Mr.
+Emory corrected. &ldquo;If you&rsquo;re really interested in
+solving the radio station mystery, I&rsquo;d advise you to
+keep watch of that rascal.&rdquo;</p>
+<p>&ldquo;But why him?&rdquo; Penny asked.</p>
+<div class="pb" id="Page_82">[82]</div>
+<p>&ldquo;I can&rsquo;t explain,&rdquo; Mr. Emory said with finality.
+&ldquo;It&rsquo;s just a tip. Take it or leave it.&rdquo;</p>
+<p>Yawning, he stretched himself full length on the
+sand and turned his back to the girls.</p>
+<div class="pb" id="Page_83">[83]</div>
+<h2 id="c11"><span class="small">CHAPTER</span>
+<br /><span class="large">11</span>
+<br /><i>A MAN OF MYSTERY</i></h2>
+<p>The following day when Penny told her
+father of Mr. Emory&rsquo;s desire to meet him, Mr. Parker
+showed little interest.</p>
+<p>&ldquo;I&rsquo;ve no time to waste getting acquainted with
+strangers,&rdquo; he said. &ldquo;Why is the man so eager to
+know me?&rdquo;</p>
+<p>&ldquo;He thinks he may be able to help you locate that
+hidden radio station.&rdquo;</p>
+<p>Mr. Parker&rsquo;s annoyance visibly increased. &ldquo;Penny,&rdquo;
+he said severely, &ldquo;you&rsquo;ve evidently been talking out
+of turn.&rdquo;</p>
+<p>&ldquo;I didn&rsquo;t mean to let him know why you&rsquo;re at Sunset
+Beach, Dad. It sort of slipped out.&rdquo;</p>
+<p>Louise, who was washing the breakfast dishes, spoke
+quickly.</p>
+<p>&ldquo;It was my fault,&rdquo; she insisted. &ldquo;Penny tried to
+stop me, but I gave the information before I thought.&rdquo;</p>
+<div class="pb" id="Page_84">[84]</div>
+<p>&ldquo;Well, it doesn&rsquo;t matter,&rdquo; Mr. Parker assured her
+kindly. &ldquo;I came here mostly for a vacation. If I
+should be lucky enough to dig up a few facts about
+the radio station, well and good. If not, no harm will
+have been done.&rdquo;</p>
+<p>&ldquo;You sent for Jerry to help you?&rdquo; Penny inquired
+curiously.</p>
+<p>Mr. Parker shook his head. &ldquo;No, I knew he was
+coming, but I didn&rsquo;t send for him. If I had, I&rsquo;m afraid
+the Army wouldn&rsquo;t have been obliging enough to
+have filled my order.&rdquo;</p>
+<p>Penny helped Louise put away the camp dishes and
+pick up loose papers. It was only eight-thirty but
+already most of the work had been done. With
+Louise to help, camping no longer was a burden.
+Even Mr. Parker seemed to have moments of enjoying
+the outdoor life.</p>
+<p>&ldquo;Anyone riding to Sunset Beach with me?&rdquo; he
+inquired cheerfully. &ldquo;I have a date with Jerry this
+morning.&rdquo;</p>
+<p>Penny and Louise both wanted to go. They washed
+at the brook, changed into becoming &ldquo;town&rdquo; dresses,
+and soon were ready.</p>
+<p>At the Crystal Inn, Jerry was not to be found. A
+clerk explained that the young man had left the hotel
+a half hour earlier but was expected to return soon.</p>
+<p>&ldquo;He probably went somewhere for breakfast or a
+walk,&rdquo; Mr. Parker remarked, sinking into a comfortable
+chair. &ldquo;I&rsquo;ll wait for him.&rdquo;</p>
+<div class="pb" id="Page_85">[85]</div>
+<p>Penny and Louise loitered in the lobby. Presently
+Mrs. Deline came from the dining room and Mr.
+Parker politely arose to greet her. The widow took
+a chair beside him and they began to chat in an animated
+way.</p>
+<p>&ldquo;Let&rsquo;s get away from here!&rdquo; Penny muttered to
+Louise. &ldquo;I don&rsquo;t like the scenery.&rdquo;</p>
+<p>The girls went outside into the warm sunshine.
+Because the Parker automobile was at the curb they
+climbed into it and sat watching the sea.</p>
+<p>&ldquo;Why do you dislike Mrs. Deline so intensely?&rdquo;
+Louise presently asked her chum.</p>
+<p>&ldquo;Because she&rsquo;s aiming to be my stepmother, that&rsquo;s
+why!&rdquo;</p>
+<p>&ldquo;Oh, Penny!&rdquo; Louise laughed outright. &ldquo;I&rsquo;m sure
+you have a mistaken idea about the entire situation.
+Your father isn&rsquo;t serious in liking her.&rdquo;</p>
+<p>&ldquo;Then he&rsquo;s certainly developed remarkable talents
+for acting,&rdquo; Penny retorted with a sniff. &ldquo;I wish
+we&rsquo;d never come to Sunset Beach.&rdquo;</p>
+<p>&ldquo;You&rsquo;d be willing to forego the mystery?&rdquo;</p>
+<p>&ldquo;Who cares about a radio station?&rdquo; Penny asked
+crossly. &ldquo;Dad won&rsquo;t tell me anything about the case,
+and probably Jerry won&rsquo;t either. It seems to be one
+of those affairs for the experts only.&rdquo;</p>
+<p>&ldquo;If I know you, Penny, you&rsquo;ll manage to get in on
+the affair,&rdquo; Louise said, her eyes twinkling.</p>
+<div class="pb" id="Page_86">[86]</div>
+<p>Penny turned on the ignition and started the car.
+&ldquo;I&rsquo;m just not interested,&rdquo; she announced flatly. &ldquo;Mrs.
+Deline has taken all the fun out of me. Want to go
+for a ride?&rdquo;</p>
+<p>&ldquo;Where?&rdquo;</p>
+<p>&ldquo;Oh, just up the beach.&rdquo;</p>
+<p>&ldquo;Isn&rsquo;t it dangerous to drive on the sand?&rdquo;</p>
+<p>&ldquo;Everyone does it at low tide. The sand is hard
+and firm along this stretch of beach.&rdquo;</p>
+<p>Louise offered no further objection, so Penny
+drove slowly away from the hotel. The car rode on
+silken tires, making only a soft swishing sound as it
+rolled smoothly over the sand.</p>
+<p>&ldquo;Oh, this is fun!&rdquo; Louise cried in delight.</p>
+<p>&ldquo;We might drive to the lighthouse,&rdquo; Penny proposed,
+steering to avoid two bathers who crossed in
+front of the car.</p>
+<p>Following the curve of the beach, the girls kept
+on until the sand became so soft that they were afraid
+to drive farther. The lighthouse was close by. Penny,
+curious to learn what sort of reception the keeper
+would accord her on the second visit, proposed to
+Louise that they call there.</p>
+<p>&ldquo;If he let Mrs. Deline visit the tower why can&rsquo;t
+we?&rdquo; she argued. &ldquo;Come along, let&rsquo;s try to get in!&rdquo;</p>
+<p>Abandoning the car on the beach, they waded
+through the dunes, climbed a fence, and ultimately
+reached the base of the tower. No one seemed to be
+in evidence. Penny started boldly up the iron steps.
+However, before she had gone very far, the keeper,
+Jim McCoy, came out on the platform.</p>
+<div class="pb" id="Page_87">[87]</div>
+<p>&ldquo;Didn&rsquo;t I tell you no visitors are allowed here?&rdquo; he
+called down angrily.</p>
+<p>&ldquo;I saw a lady come here yesterday!&rdquo; Penny returned.</p>
+<p>&ldquo;You must have dreamed it,&rdquo; retorted the lighthouse
+keeper. &ldquo;No visitors allowed. Don&rsquo;t make
+me tell you again!&rdquo;</p>
+<p>Penny retreated, decidedly crushed.</p>
+<p>&ldquo;You asked for it, kitten,&rdquo; Louise teased as they
+walked toward the car. &ldquo;I don&rsquo;t blame the keeper
+for not wanting visitors.&rdquo;</p>
+<p>&ldquo;Mrs. Deline was there,&rdquo; Penny insisted stubbornly.
+&ldquo;Why should he deny it?&rdquo;</p>
+<p>Half way to the car, the girls paused to pick up a
+few large shells lying in the deep sand. The task became
+an absorbing one. Before they realized it, the
+sun was high overhead and their faces were being
+burned by the direct rays.</p>
+<p>&ldquo;Let&rsquo;s go,&rdquo; Louise urged. &ldquo;The tide turned a long
+while ago. We should be returning to the hotel.&rdquo;</p>
+<p>&ldquo;Okay,&rdquo; Penny agreed. She stooped to pick up
+another shell. As she straightened, she observed an
+old man in ragged clothing coming down the beach.</p>
+<p>&ldquo;Lou,&rdquo; she said in a low tone, &ldquo;there&rsquo;s that same
+man Mr. Emory was telling us about!&rdquo;</p>
+<p>&ldquo;The beachcomber?&rdquo; Louise turned to stare.</p>
+<div class="pb" id="Page_88">[88]</div>
+<p>&ldquo;Yes, and he&rsquo;s coming this way. Perhaps it might
+be worth while to watch him.&rdquo;</p>
+<p>&ldquo;He&rsquo;s not seen us yet.&rdquo;</p>
+<p>Penny glanced about for a hiding place. The only
+one that offered was a huge sand dune. Pulling Louise
+along with her, she crouched down out of sight.</p>
+<p>In a moment the old beachcomber came along. He
+was whistling and seemed to have not a care in the
+world. His face, viewed at close range, was weather-beaten,
+his hair uncombed, and his clothing had not
+been washed in many a day.</p>
+<p>&ldquo;What&rsquo;s so mysterious about him?&rdquo; Louise whispered.
+&ldquo;Why did Mr. Emory say he&rsquo;d bear watching?&rdquo;</p>
+<p>&ldquo;Maybe he&rsquo;s not really a beachcomber,&rdquo; Penny returned,
+low. &ldquo;He may be an Enemy Agent in disguise.&rdquo;</p>
+<p>&ldquo;You have Enemy Agents on the brain!&rdquo; Louise
+chuckled. &ldquo;Likewise, man-snatching widows.&rdquo;</p>
+<p>The beachcomber passed within a few feet of the
+girls. He crossed the courtyard of the lighthouse
+and was seen to take a trail which led amid the rocks.</p>
+<p>&ldquo;Lou, perhaps he&rsquo;s going to one of the caves!&rdquo;
+Penny cried. &ldquo;You know Mr. Emory said this locality
+is honeycombed with them.&rdquo;</p>
+<p>&ldquo;Let him go,&rdquo; Louise answered indifferently. &ldquo;It&rsquo;s
+lunch time and I&rsquo;m hungry.&rdquo;</p>
+<div class="pb" id="Page_89">[89]</div>
+<p>&ldquo;Your appetite will have to wait. I&rsquo;m going to
+follow that man!&rdquo;</p>
+<p>&ldquo;Oh, Penny.&rdquo;</p>
+<p>&ldquo;But this may be important.&rdquo;</p>
+<p>&ldquo;And it may be just another of your so-called
+bright ideas,&rdquo; Louise retorted. &ldquo;Well, lead on, and
+let&rsquo;s get it over with.&rdquo;</p>
+<p>The beachcomber already had disappeared amid
+the mass of piled-up rock farther back from shore.
+Penny had marked the locality well with her eye.
+She was able to lead Louise to the place where he
+had vanished.</p>
+<p>&ldquo;See, there&rsquo;s a well-worn trail,&rdquo; she indicated triumphantly.
+&ldquo;He must have taken it.&rdquo;</p>
+<p>They followed the path, and a moment later caught
+a fleeting glimpse of the beachcomber. At times the
+trail was so narrow that the girls barely could squeeze
+between the rocks. Wind whistled around the cliffs,
+whipping hair and blowing skirts.</p>
+<p>Unexpectedly, Penny, who was in the lead, came
+to the low entranceway of a cave.</p>
+<p>&ldquo;He must have gone in there!&rdquo; she declared excitedly.
+&ldquo;Listen!&rdquo;</p>
+<p>From deep within the cave the girls could hear a
+strange sound.</p>
+<p>&ldquo;Rushing water!&rdquo; Louise said in awe. &ldquo;The Cave
+must have a waterfall or an underground river.&rdquo;</p>
+<div class="pb" id="Page_90">[90]</div>
+<p>&ldquo;We&rsquo;ll soon know.&rdquo; Penny started into the cave
+only to have Louise clutch at her hand.</p>
+<p>&ldquo;Don&rsquo;t be silly, Penny. We have no flashlight.&rdquo;</p>
+<p>&ldquo;But we can&rsquo;t let that beachcomber get away. We
+want to learn what he does.&rdquo;</p>
+<p>&ldquo;I can bear up without knowing.&rdquo;</p>
+<p>&ldquo;Well, I can&rsquo;t,&rdquo; Penny announced with equal firmness.</p>
+<p>&ldquo;But it may be dangerous. Let&rsquo;s go back to the
+hotel and get Jerry or your father.&rdquo;</p>
+<p>Penny hesitated, then shook her head. &ldquo;You stay
+here if you like, Lou,&rdquo; she replied. &ldquo;I&rsquo;m going inside.&rdquo;</p>
+<p>Before her chum could detain her, she stooped low
+and crawled into the narrow, dark tunnel.</p>
+<div class="pb" id="Page_91">[91]</div>
+<h2 id="c12"><span class="small">CHAPTER</span>
+<br /><span class="large">12</span>
+<br /><i>CAUGHT BY THE TIDE</i></h2>
+<p>Unwilling to be left behind, Louise followed
+her chum into the dark cavern. Once she and Penny
+were well beyond the yawning mouth of the cave,
+they could not see a foot ahead of them. Guided by
+the sound of rushing water, they groped their way
+along a damp wall.</p>
+<p>&ldquo;This is awful!&rdquo; Louise whispered nervously.
+&ldquo;Let&rsquo;s turn back.&rdquo;</p>
+<p>Penny might have yielded to her chum&rsquo;s coaxing
+but at that moment the tunnel broadened out and became
+lighter. Directly ahead a series of steps led
+down to a lower room of the cave.</p>
+<p>&ldquo;This place must be safe enough or steps wouldn&rsquo;t
+have been built here,&rdquo; she whispered. &ldquo;Don&rsquo;t be
+nervous, Lou. We may discover something important.&rdquo;</p>
+<div class="pb" id="Page_92">[92]</div>
+<p>Louise muttered that they were more likely to
+break their necks. However, she cautiously followed
+Penny down the rock-hewn steps. Half way
+down, they both paused. From below came a weird
+sound.</p>
+<p>&ldquo;What was that?&rdquo; Louise whispered.</p>
+<p>&ldquo;It sounded for all the world like the note of a
+pipe organ!&rdquo; Penny observed. &ldquo;There it is again&mdash;a
+different tone this time.&rdquo;</p>
+<p>Noiselessly the girls moved on down the steps.
+Ahead of them they now could see a moving light
+which undoubtedly was a flash lantern carried by the
+beachcomber. Drawing closer, they saw the man
+himself. In the great cavern his shadow appeared
+grotesque and huge.</p>
+<p>&ldquo;What is he doing?&rdquo; Louise whispered in awe.</p>
+<p>The man was unaware that he had been followed.
+He stood in the center of the great chamber, gazing
+with wrapt expression at the stalagmites which rose
+in strange formations from the cave floor. The girls
+could hear him muttering to himself. At the risk of
+being seen they moved closer.</p>
+<p>&ldquo;Music! Music!&rdquo; the old man mumbled. &ldquo;Talk
+about your pipe organs! They ain&rsquo;t in it with <i>this</i>!&rdquo;</p>
+<p>He held a long stick in his hand and with it began
+to explore the row of stalagmites, striking them one
+by one, at first with a slow tempo and then faster and
+faster. The weird sounds echoed and reached
+through the galleries of the cavern.</p>
+<div class="pb" id="Page_93">[93]</div>
+<p>&ldquo;Pretty!&rdquo; the old man prattled. &ldquo;It&rsquo;s the music o&rsquo;
+Heaven. There ain&rsquo;t no music to equal it.&rdquo;</p>
+<p>Again the beachcomber struck the stalagmites, listening
+raptly while the sounds died slowly away.</p>
+<p>&ldquo;Come on, Penny,&rdquo; Louise urged, tugging at her
+hand. &ldquo;Let&rsquo;s get out of here. That old goof has
+lost his buttons.&rdquo;</p>
+<p>Decidedly crestfallen, Penny permitted herself to
+be pulled along the passage and up the steps. As the
+girls groped their way to the cave&rsquo;s mouth, they still
+could hear the weird echoing tones.</p>
+<p>&ldquo;That was a good joke on you!&rdquo; Louise teased.
+&ldquo;You thought you were going to find a hidden radio
+station!&rdquo;</p>
+<p>&ldquo;Well, we did find a cave,&rdquo; Penny said defensively.</p>
+<p>&ldquo;We didn&rsquo;t exactly discover it,&rdquo; Louise amended.
+&ldquo;This must be Crystal Cave. Seemingly that old
+beachcomber regards it as his own personal property.&rdquo;</p>
+<p>&ldquo;Mr. Emory certainly gave us a wrong steer. A
+mysterious character, my eye!&rdquo;</p>
+<p>&ldquo;You&rsquo;ll admit that the old fellow is interesting,&rdquo;
+Louise laughed. &ldquo;However, I doubt he&rsquo;ll warrant
+much attention from the FBI.&rdquo;</p>
+<p>&ldquo;All right, laugh,&rdquo; Penny retorted grimly. &ldquo;You
+think my detective efforts are a joke anyway.&rdquo;</p>
+<div class="pb" id="Page_94">[94]</div>
+<p>&ldquo;No, I don&rsquo;t, Penny. But I will say I doubt you&rsquo;ll
+have success tracing a hidden radio station. After
+all, it&rsquo;s a problem that has the State authorities baffled.
+Not to mention Uncle Sam&rsquo;s Army.&rdquo;</p>
+<p>The girls stepped from the cave out into the brilliant
+sunshine. Gazing toward the sea, they were
+amazed to see how high the tide had risen. Giant
+waves were washing very close to the Parker automobile
+left on the beach.</p>
+<p>&ldquo;Ye fishes!&rdquo; Penny exclaimed in horror. &ldquo;I forgot
+all about the car!&rdquo;</p>
+<p>&ldquo;And the tide&rsquo;s coming in fast!&rdquo;</p>
+<p>&ldquo;The Point will be cut off in a few more minutes!&rdquo;
+Penny added, recalling Mr. Emory&rsquo;s warning. &ldquo;We&rsquo;ll
+have to travel, and travel fast!&rdquo;</p>
+<p>Scrambling down from the rocks, the girls plunged
+through the dunes to the beach. A wind was blowing
+and the sea had an angry look.</p>
+<p>&ldquo;If just one wave strikes the car, the wheels will
+sink in the sand, and then we&rsquo;ll be in it!&rdquo; Penny cried.</p>
+<p>With increasing alarm she noted that sand was
+damp within a foot of the rear wheels. And as she
+jerked open the car door, a greedy wave nipped again
+at the rubber.</p>
+<p>&ldquo;We&rsquo;ll soon be out of here,&rdquo; Louise said encouragingly.</p>
+<p>Penny stepped on the starter and to her relief the
+motor caught instantly. In great haste she turned
+the car around, circling away from the inrushing sea.</p>
+<div class="pb" id="Page_95">[95]</div>
+<p>&ldquo;Careful!&rdquo; Louise warned. &ldquo;The sand is dreadfully
+soft this far up shore.&rdquo;</p>
+<p>Too late Penny realized the same thing. She could
+feel the car starting to bog down. The motor began
+to labor. Then the car stalled completely.</p>
+<p>&ldquo;We&rsquo;re stuck!&rdquo; she gasped.</p>
+<p>Both girls sprang out to look at the wheels. Their
+spirits sank. On one side, front and rear tires were
+bogged deep in sand.</p>
+<p>&ldquo;Start the engine again!&rdquo; Louise urged desperately.
+&ldquo;I&rsquo;ll try to push.&rdquo;</p>
+<p>Penny obeyed, but her chum&rsquo;s puny strength made
+not the slightest impression upon the car. It could
+not be moved a foot. The spinning wheels only
+drove deeper and deeper into the sand.</p>
+<p>&ldquo;What shall we do?&rdquo; Louise asked helplessly. She
+turned to stare at the incoming sea. Each wave was
+breaking a little closer to the car.</p>
+<p>&ldquo;This place will be under in another twenty minutes,&rdquo;
+Penny calculated. &ldquo;Even if the car isn&rsquo;t washed
+away, the salt water will ruin it. How did we ever
+get into such a mess?&rdquo;</p>
+<p>&ldquo;Just by being careless. If only we weren&rsquo;t so far
+from the hotel!&rdquo;</p>
+<p>&ldquo;I&rsquo;ll run to the lighthouse,&rdquo; Penny decided desperately.
+&ldquo;Maybe the keeper will help us.&rdquo;</p>
+<div class="pb" id="Page_96">[96]</div>
+<p>Both girls were badly frightened, not for their own
+safety, but because they feared that the car would be
+damaged beyond repair. Once the waves began to
+strike it, it would sink deeper and deeper into the
+sand. Salt water would corrode all of the bright
+chromium.</p>
+<p>&ldquo;We&rsquo;ve no time to waste!&rdquo; Penny cried, darting
+away.</p>
+<p>The girls plunged through the sand drifts to the
+lighthouse. Evidently the keeper already had observed
+their plight, for he was standing on the upper
+platform peering down into the courtyard.</p>
+<p>&ldquo;Our car is stuck in the sand!&rdquo; Penny shouted.
+&ldquo;Can you help us get it out?&rdquo;</p>
+<p>&ldquo;No, I can&rsquo;t,&rdquo; the keeper answered gruffly. &ldquo;You
+should have watched the tide.&rdquo;</p>
+<p>&ldquo;There&rsquo;s no one else to help us,&rdquo; Penny pleaded.
+&ldquo;Just a little push&mdash;&rdquo;</p>
+<p>&ldquo;I&rsquo;m forbidden to leave my post.&rdquo;</p>
+<p>&ldquo;Then will you telephone to the Inn? Or to a
+garage?&rdquo;</p>
+<p>&ldquo;I could &rsquo;phone but it wouldn&rsquo;t do any good,&rdquo; the
+keeper said reluctantly. &ldquo;Your car will be under
+water before a tow-car could get here.&rdquo;</p>
+<p>Exasperated by the man&rsquo;s unwillingness to help,
+Louise and Penny ran back to the car. Already waves
+were lapping against the rear wheels. The situation
+seemed hopeless.</p>
+<p>&ldquo;Shall I try to push again?&rdquo; Louise asked.</p>
+<div class="pb" id="Page_97">[97]</div>
+<p>&ldquo;It wouldn&rsquo;t do any good. We&rsquo;re not strong
+enough.&rdquo; In desperation, Penny&rsquo;s gaze wandered
+down the deserted shore. Suddenly she saw a lone
+fisherman who was wading through the surf. She
+recognized him as George Emory.</p>
+<p>&ldquo;He&rsquo;ll help us!&rdquo; she cried confidently.</p>
+<p>The girls shouted Mr. Emory&rsquo;s name. Apparently
+he heard, for he turned his head quickly. Their
+plight, they thought, must be instantly evident, but
+Mr. Emory did not seem to comprehend. He waved
+his hand as if in friendly greeting, and then, reeling
+in his fish line, turned and walked away from them.</p>
+<div class="pb" id="Page_98">[98]</div>
+<h2 id="c13"><span class="small">CHAPTER</span>
+<br /><span class="large">13</span>
+<br /><i>A HIDDEN PACKAGE</i></h2>
+<p>&ldquo;Why, Mr. Emory doesn&rsquo;t understand!&rdquo; Penny
+cried, aghast. &ldquo;Can&rsquo;t he see that we&rsquo;re stuck here
+with the tide rolling in?&rdquo;</p>
+<p>The girls shouted again and again. If the man
+heard, he gave no sign.</p>
+<p>&ldquo;I don&rsquo;t believe he wanted to help us!&rdquo; Penny declared
+furiously. &ldquo;Probably he&rsquo;s afraid he&rsquo;ll over-strain
+himself pushing!&rdquo;</p>
+<p>Unwilling to give up without a last try, she sprang
+into the car and once more started the engine. It
+roared and labored but could not pull the vehicle.
+Sick with despair, Penny allowed the motor to idle.
+She slumped behind the steering wheel, only to
+straighten suddenly as she thought she heard her
+name called.</p>
+<div class="pb" id="Page_99">[99]</div>
+<p>Louise too heard the cry for she turned quickly
+toward the main road some yards back from the
+beach. A young man in uniform was running across
+the dunes toward the girls.</p>
+<p>&ldquo;It&rsquo;s Jerry!&rdquo; Penny cried jubilantly. &ldquo;He&rsquo;ll help
+us!&rdquo;</p>
+<p>&ldquo;He will if he can,&rdquo; Louise corrected. &ldquo;The tide&rsquo;s
+coming in so fast now. I doubt anyone can get us
+out of here now.&rdquo;</p>
+<p>Jerry did not waste time asking questions. Taking
+in the situation at a glance, he instructed Penny to
+remain at the wheel. With the motor racing, he and
+Louise pushed with all their strength. At first the
+rear wheels kept spinning in the sand. A great wave
+slapped the rear end of the car, spraying Louise from
+head to foot.</p>
+<p>&ldquo;It&rsquo;s no use!&rdquo; she gasped. &ldquo;We can&rsquo;t do it.&rdquo;</p>
+<p>&ldquo;Yes, we can!&rdquo; Jerry insisted. &ldquo;Try once more,
+Louise.&rdquo;</p>
+<p>Again they pushed and this time the car actually
+moved a few feet before it bogged down. Encouraged,
+Jerry and Louise tried harder than before. The
+wheels suddenly struck firm sand, dug in, and the
+car began to creep forward. Penny kept it moving
+until she was sure the footing beneath the tires was
+solid. Then she pulled up so that Jerry and Louise
+might leap aboard.</p>
+<p>&ldquo;Drive as fast as you can for the hotel!&rdquo; Jerry instructed
+crisply. &ldquo;We&rsquo;ll be lucky to make it.&rdquo;</p>
+<div class="pb" id="Page_100">[100]</div>
+<p>Where an hour before the roadway along the
+beach had been wide and ample, there now was only
+a fringe of white sand. To avoid the incoming waves,
+Penny had to drive dangerously close to the dunes.
+And midway to the hotel, they came to a flooded
+stretch of beach.</p>
+<p>&ldquo;We&rsquo;ll have to risk it,&rdquo; Jerry advised as Penny
+hesitated to drive on.</p>
+<p>The water was not deep but the sand was wet and
+treacherous. Choosing a moment between breakers,
+Penny braved it, and to her intense relief the car
+rolled through without sinking down.</p>
+<p>&ldquo;It&rsquo;s clear sailing now,&rdquo; Jerry said as a wider strip
+of beach opened before them. &ldquo;We&rsquo;re well beyond
+the Point.&rdquo;</p>
+<p>Mr. Emory was walking along the shore and as the
+car went past, he waved his hand in a friendly way.
+Penny did not bother to return the salute, pretending
+she did not see him.</p>
+<p>&ldquo;I&rsquo;m sure he knew we were in trouble and didn&rsquo;t
+want to help,&rdquo; she told Jerry. &ldquo;The more I see of
+that man the less I like him.&rdquo;</p>
+<p>&ldquo;Who is he anyhow?&rdquo;</p>
+<p>&ldquo;Just a vacationer. He got Lou and me all excited
+yesterday with his talk about that hidden radio station.&rdquo;</p>
+<p>&ldquo;How do you mean?&rdquo; Jerry asked with interest.</p>
+<div class="pb" id="Page_101">[101]</div>
+<p>Penny repeated the conversation, and mentioned
+how Mr. Emory had suggested that the old beachcomber
+was a mysterious character that would bear
+watching.</p>
+<p>&ldquo;Not old Jake Skagway?&rdquo; Jerry asked, amused.</p>
+<p>&ldquo;I believe that was his name.&rdquo;</p>
+<p>&ldquo;Jake&rsquo;s the only beachcomber I know hereabouts.
+He makes his living picking up things on the beach
+and selling them. Folks say he buries some of his
+loot in the caves.&rdquo;</p>
+<p>&ldquo;How do you know so much about him, Jerry?&rdquo;</p>
+<p>&ldquo;Oh, I used to run down to Sunset Beach real often
+years ago. I know this locality like a book. Guess
+that&rsquo;s why the Army sent me here to do a little scouting
+around.&rdquo;</p>
+<p>Penny waited expectantly, but Jerry offered no
+more information as to the reason for his visit to Sunset
+Beach.</p>
+<p>&ldquo;Probably Lou and I were taken in by Jake Skagway,&rdquo;
+she admitted after a moment. &ldquo;If we hadn&rsquo;t
+followed him into the cave, we certainly wouldn&rsquo;t
+have involved ourselves in such difficulties.&rdquo;</p>
+<p>Upon reaching the Crystal Inn a few minutes
+later, the girls searched for Mr. Parker. He was nowhere
+to be found. After waiting for a time, they
+left the car with Jerry and hiked to the forest camp.
+There the early afternoon was devoted to camp tasks.
+When Mr. Parker still did not come, Penny proposed
+that they return to Sunset Beach for a plunge in the
+surf.</p>
+<div class="pb" id="Page_102">[102]</div>
+<p>&ldquo;Too cold,&rdquo; Louise shivered.</p>
+<p>&ldquo;Well, let&rsquo;s go down to Sunset Beach anyhow,&rdquo;
+Penny urged. &ldquo;I get restless just sitting here in
+camp.&rdquo;</p>
+<p>&ldquo;You know you want to see Jerry again,&rdquo; Louise
+teased. &ldquo;&rsquo;Fess up.&rdquo;</p>
+<p>&ldquo;All right, I do want to see him,&rdquo; Penny admitted
+unabashed. &ldquo;Jerry&rsquo;s my very best friend. I&rsquo;ve not
+been with him in months and I suppose in a few days
+he&rsquo;ll be shot off to goodness-knows-where.&rdquo;</p>
+<p>&ldquo;He&rsquo;s not told you very much about why he came
+here.&rdquo;</p>
+<p>&ldquo;No,&rdquo; Penny said briefly. The subject was a sore
+one with her. She felt that both her father and Jerry
+were keeping secrets.</p>
+<p>The tide was still high when the girls reached the
+beach, but the flow was outward. Sprawling in the
+warm sand, they watched the gulls.</p>
+<p>&ldquo;Wonder what became of Jerry and Dad?&rdquo; Penny
+speculated. &ldquo;They&rsquo;re probably together somewhere.&rdquo;</p>
+<p>&ldquo;Or with Mrs. Deline,&rdquo; Louise suggested wickedly.</p>
+<p>She was sorry that she had spoken for Penny&rsquo;s face
+immediately became as black as a thundercloud.</p>
+<p>&ldquo;Sorry,&rdquo; Louise apologized. &ldquo;I was only joking.&rdquo;</p>
+<p>Penny continued to scowl for at that moment she
+glimpsed Mrs. Deline walking rapidly down the
+beach. The widow came from the direction of the
+lighthouse and was alone. To avoid the incoming
+waves she waded ankle deep through the great sand
+ridges along the drift fence.</p>
+<div class="pb" id="Page_103">[103]</div>
+<p>&ldquo;That&rsquo;s queer,&rdquo; Penny muttered, sitting up.</p>
+<p>&ldquo;What is?&rdquo;</p>
+<p>&ldquo;Why, Mrs. Deline apparently has been at the
+lighthouse again. What&rsquo;s she doing now?&rdquo;</p>
+<p>The widow had paused. Carefully she gazed up
+and down the deserted shore, but she did not see
+Penny and Louise who were hidden from view by
+a sand dune. However, by raising up slightly, they
+could see her plainly.</p>
+<p>Mrs. Deline carried a package of considerable size
+under her arm. Seemingly satisfied that no one was
+at hand to observe her actions, she moved swiftly to
+one of the sand dunes near the drift fence. As the
+girls watched in amazement, she dug a deep hole and
+buried the package. Her work completed, she carefully
+brushed sand over the spot and obliterated her
+own footprints one by one.</p>
+<p>&ldquo;What was the idea of that?&rdquo; Louise asked in bewilderment.</p>
+<p>&ldquo;That&rsquo;s what I want to know!&rdquo; Penny muttered.
+&ldquo;We&rsquo;ll wait until she leaves and then find out the contents
+of that package!&rdquo;</p>
+<p>But Mrs. Deline did not immediately go away. Instead
+she sat down in the sand close by. The girls
+could not see very well but they thought she was
+writing something on the skirt of her white suit.</p>
+<div class="pb" id="Page_104">[104]</div>
+<p>&ldquo;Why is she doing that?&rdquo; Louise asked in bewilderment.</p>
+<p>&ldquo;I&rsquo;ll bet a cookie she&rsquo;s writing down the location
+of what she hid in the sand dune!&rdquo; Penny speculated.
+&ldquo;That&rsquo;s so she can find it again!&rdquo;</p>
+<p>&ldquo;But why write it on her skirt? And why should
+she hide anything here on the beach?&rdquo;</p>
+<p>&ldquo;Because she&rsquo;s a spy!&rdquo; Penny declared triumphantly.
+&ldquo;I&rsquo;ve been suspicious of her from the first!&rdquo;</p>
+<p>&ldquo;Yes, you have, darling,&rdquo; agreed Louise. &ldquo;But
+would a spy necessarily hide a package? If Mrs.
+Deline had information to communicate wouldn&rsquo;t she
+send it to her superiors? Besides, Sunset Beach isn&rsquo;t
+even an important manufacturing town.&rdquo;</p>
+<p>&ldquo;That&rsquo;s true. But I&rsquo;ve heard Dad say that the
+Coast Guards watch this place closely. Because of its
+isolation and jagged coastline it&rsquo;s considered a likely
+spot for surprise night landings by the Enemy.&rdquo;</p>
+<p>&ldquo;Only this morning you thought old Jake Skagway
+was a rascal,&rdquo; Louise chuckled. &ldquo;You don&rsquo;t catch
+me falling for your theories this time.&rdquo;</p>
+<p>&ldquo;Then you have no interest in that hidden package?&rdquo;</p>
+<p>&ldquo;Of course I have! I merely don&rsquo;t agree that Mrs.
+Deline is a spy.&rdquo;</p>
+<p>&ldquo;Quiet!&rdquo; Penny warned. &ldquo;Here she comes!&rdquo;</p>
+<div class="pb" id="Page_105">[105]</div>
+<p>Mrs. Deline had arisen from the sand and came rapidly
+down the beach. She did not see the girls until
+she was very close to them. Involuntarily, she
+paused, and looked somewhat disconcerted. Recovering,
+she spoke coldly.</p>
+<p>&ldquo;Hello,&rdquo; Penny responded, her gaze on the
+woman&rsquo;s white flannel skirt. It bore not a single tell-tale
+mark.</p>
+<p>Mrs. Deline went on down the beach.</p>
+<p>&ldquo;You see,&rdquo; Louise whispered when the woman was
+beyond hearing, &ldquo;she didn&rsquo;t write anything on her
+dress.&rdquo;</p>
+<p>&ldquo;But we saw her do it!&rdquo;</p>
+<p>&ldquo;We only thought we did.&rdquo;</p>
+<p>&ldquo;Maybe she wrote it in invisible ink.&rdquo;</p>
+<p>&ldquo;Oh, Penny, you certainly have an imagination,&rdquo;
+Louise sighed.</p>
+<p>&ldquo;I suppose I imagined about the package too?&rdquo;</p>
+<p>&ldquo;No, she really did bury something in the sand.&rdquo;</p>
+<p>&ldquo;Then what are we waiting for?&rdquo; Penny demanded,
+leaping to her feet. &ldquo;Let&rsquo;s dig it up, and
+then maybe we&rsquo;ll have the answer to a few of our
+questions.&rdquo;</p>
+<div class="pb" id="Page_106">[106]</div>

+<br /><i>VOICE FROM THE CAVE</i></h2>
+<p>From a distance Penny and Louise had marked well
+the spot where Mrs. Deline had buried the package.
+But as they approached the drift fence all of the dunes
+seemed strikingly similar in appearance. They could
+not agree as to the exact mound which contained the
+hidden package.</p>
+<p>&ldquo;It was buried in this one, I think,&rdquo; Penny said,
+starting to dig. &ldquo;Mrs. Deline certainly did a good job
+of covering her tracks.&rdquo;</p>
+<p>&ldquo;You&rsquo;re wasting time working on that dune,&rdquo;
+Louise insisted. &ldquo;I&rsquo;ll get busy over here and turn up
+the package in nothing flat.&rdquo;</p>
+<p>Selecting a mound of sand several feet from Penny,
+she began to dig with a will. The mysterious package
+proved elusive. Scarcely had the girls started work
+than a few raindrops splattered down.</p>
+<p>&ldquo;Oh, it&rsquo;s going to storm!&rdquo; Louise exclaimed, turning
+startled eyes toward the dark sea.</p>
+<div class="pb" id="Page_107">[107]</div>
+<p>The rain came down faster and faster. Faced with
+a choice of abandoning the search or being drenched,
+the girls decided to make a dash for the hotel.</p>
+<p>As they darted up the steps at the Crystal Inn,
+they were surprised to see Mrs. Deline sitting on the
+veranda. A spyglass lay in her lap. Whether she
+had been watching the sea or their own antics they
+had no way of knowing.</p>
+<p>&ldquo;Have you seen my father, Mrs. Deline?&rdquo; Penny
+asked, shaking the raindrops from her flying hair.</p>
+<p>&ldquo;Indeed, I don&rsquo;t keep track of his whereabouts,&rdquo;
+Mrs. Deline replied coldly. &ldquo;By the way, did you
+find what you were searching for in the sand?&rdquo;</p>
+<p>The question caught Penny off guard. She stammered
+a few words which only caused the widow to
+smile in a knowing, amused way.</p>
+<p>&ldquo;I don&rsquo;t mind telling you what I buried in the
+sand,&rdquo; she resumed. &ldquo;It may save you a little trouble.
+The package contained nothing but fish bones.&rdquo;</p>
+<p>&ldquo;Fish bones!&rdquo;</p>
+<p>&ldquo;Yes, I had just visited my friend, Jim McCoy, at
+the lighthouse. It&rsquo;s most difficult to bury anything
+there because of so many rocks. He asked me to dispose
+of the scraps for him.&rdquo;</p>
+<p>&ldquo;Oh,&rdquo; Penny murmured, completely deflated.</p>
+<p>&ldquo;I&rsquo;ve been watching you girls through the spyglass,&rdquo;
+Mrs. Deline went on. &ldquo;It really was amusing.&rdquo;</p>
+<div class="pb" id="Page_108">[108]</div>
+<p>&ldquo;I can imagine,&rdquo; Penny agreed grimly. &ldquo;Oh, well,
+I&rsquo;m glad to provide a little amusement for this dead
+place.&rdquo;</p>
+<p>She and Louise retreated until they were screened
+from the widow by a potted palm.</p>
+<p>&ldquo;I guess she scored on you that time, Penny,&rdquo; Louise
+commented. &ldquo;So we wasted our strength digging
+for garbage!&rdquo;</p>
+<p>&ldquo;You needn&rsquo;t rub it in.&rdquo;</p>
+<p>&ldquo;But it&rsquo;s all so silly. Why don&rsquo;t we try to like Mrs.
+Deline, Penny?&rdquo;</p>
+<p>&ldquo;I&rsquo;ll leave that job up to you. Furthermore, how
+do I know she was telling the truth? Maybe she just
+handed us that story so we wouldn&rsquo;t go on digging in
+the dunes!&rdquo;</p>
+<p>&ldquo;That&rsquo;s so!&rdquo; Louise acknowledged. &ldquo;Mrs. Deline
+isn&rsquo;t the type to be doing gracious little jobs for
+anyone.&rdquo;</p>
+<p>&ldquo;If Jim McCoy asked her to bury a package of
+garbage, she would have disposed of it long before she
+did,&rdquo; Penny reasoned. &ldquo;Instead, she walked quite a
+distance down shore. Then she seemed to select a
+particular dune, as if by pre-arrangement.&rdquo;</p>
+<p>&ldquo;You think she may have hidden something there
+expecting another person to pick it up?&rdquo;</p>
+<p>&ldquo;That&rsquo;s my theory, Lou. Oh, I wish this rain
+would let up.&rdquo;</p>
+<div class="pb" id="Page_109">[109]</div>
+<p>Restlessly Penny walked to a window. The rain
+showed signs of slackening. And as she watched, a
+taxi drew up in front of the hotel. Jerry Livingston
+leaped out.</p>
+<p>&ldquo;Wait for me!&rdquo; he instructed the driver. &ldquo;I&rsquo;ll be
+right back.&rdquo;</p>
+<p>Penny and Louise managed to block Jerry&rsquo;s path
+as he came hurrying into the hotel.</p>
+<p>&ldquo;Hello, girls,&rdquo; he greeted them offhanded. &ldquo;Want
+to go for a drive into the country?&rdquo;</p>
+<p>&ldquo;We certainly do,&rdquo; Penny accepted for both.
+&ldquo;What&rsquo;s our destination?&rdquo;</p>
+<p>&ldquo;Tell you on the way,&rdquo; Jerry answered.</p>
+<p>He disappeared into an elevator, but was back in
+the lobby within a few minutes. Taking Penny and
+Louise each by an elbow, he escorted them to the
+waiting cab.</p>
+<p>&ldquo;In a way, this is a secret trip,&rdquo; he said after he had
+given directions to the driver. &ldquo;Ever see a radio monitoring
+truck?&rdquo;</p>
+<p>&ldquo;Never even heard of one,&rdquo; Penny replied. &ldquo;What
+is it?&rdquo;</p>
+<p>&ldquo;Well, we have a truck equipped so that our instruments
+pick up the direction from which any short
+wave broadcast is sent. It&rsquo;s not generally known
+that the Army&rsquo;s at work here, so whatever you girls
+see you must keep under your sunbonnets.&rdquo;</p>
+<div class="pb" id="Page_110">[110]</div>
+<p>The taxi sped along the country road, following
+a route that was unfamiliar to the girls. By the time
+it drew up several miles from Sunset Beach the rain
+had ceased.</p>
+<p>&ldquo;Tumble out,&rdquo; Jerry said, opening the cab door.
+&ldquo;This is the end of the line.&rdquo;</p>
+<p>He went ahead, breaking a hole in the tall hedge
+at one side of the road. Eagerly the girls followed
+him through the gap. In a clearing just beyond a
+clump of saplings stood what appeared to be an ordinary
+covered Army truck.</p>
+<p>An enlisted man came toward Jerry and the girls,
+saluting smartly.</p>
+<p>&ldquo;Are you picking up any signals?&rdquo; Jerry asked
+him.</p>
+<p>&ldquo;Nothing yet, sir. The weather hasn&rsquo;t been very
+favorable.&rdquo;</p>
+<p>&ldquo;You&rsquo;ve had your equipment set up here two days
+now?&rdquo;</p>
+<p>&ldquo;Right, sir.&rdquo;</p>
+<p>&ldquo;It&rsquo;s not likely we&rsquo;ll get anything today or tonight,&rdquo;
+Jerry replied. &ldquo;Oh, well, we&rsquo;ll have to have
+patience. Sooner or later the station will go on the
+air again, and then we&rsquo;ll learn its location.&rdquo;</p>
+<p>Louise and Penny were curious to learn more about
+the monitoring truck. Jerry took them inside, introduced
+them to the officers, and showed them the radio
+apparatus.</p>
+<div class="pb" id="Page_111">[111]</div>
+<p>&ldquo;Our truck is equipped with rotating antennae,&rdquo;
+he explained. &ldquo;Whenever the unknown station starts
+to broadcast we&rsquo;ll be able to swing our loops toward
+the signals. Then we chart the signals and where the
+lines intercept, the station is located.&rdquo;</p>
+<p>&ldquo;As you explain it, Jerry, finding any radio station
+is a simple matter.&rdquo;</p>
+<p>&ldquo;It is, providing the station doesn&rsquo;t move in the
+meantime. Unfortunately, Mr. Voice from the Cave
+is an elusive fellow.&rdquo;</p>
+<p>&ldquo;You have no idea who the man may be?&rdquo;</p>
+<p>&ldquo;No, he&rsquo;s known to FBI agents only as B4 which is
+a code number.&rdquo;</p>
+<p>&ldquo;What is the purpose behind the broadcasts?&rdquo;
+Louise inquired. &ldquo;Enemy propaganda?&rdquo;</p>
+<p>&ldquo;We know that the station is enemy owned and
+operated,&rdquo; Jerry replied. &ldquo;So far that&rsquo;s about all we
+do know, for we&rsquo;ve been unable to break the code.
+We suspect that persons connected with the station
+may be aiding German prisoners to escape from the
+country.&rdquo;</p>
+<p>&ldquo;Prisoners originally held in Canada?&rdquo; Penny inquired.</p>
+<p>&ldquo;Yes, they&rsquo;ve been aided by a ring of very clever
+spies.&rdquo;</p>
+<p>Penny was silent as she thought over the information.
+There were many questions she longed to ask.</p>
+<p>&ldquo;Jerry&mdash;&rdquo; she began, but just then there came an
+interruption.</p>
+<div class="pb" id="Page_112">[112]</div>
+<p>In the Army truck an officer had adjusted his earphones.
+His attitude as he listened was one of tense
+expectancy.</p>
+<p>&ldquo;Picking up any signals?&rdquo; Jerry demanded.</p>
+<p>The other man nodded. &ldquo;Something&rsquo;s coming in!
+Yes, it&rsquo;s our friend, the Voice. In just a minute we
+should know exactly where the station is located.&rdquo;</p>
+<p>Jerry and the girls remained in the truck, eagerly
+awaiting a report from the efficient men who manned
+the radio direction finders.</p>
+<p>&ldquo;Okay, we&rsquo;ve got it charted!&rdquo; came the terse announcement
+a moment later.</p>
+<p>&ldquo;Where&rsquo;s the station located?&rdquo; Jerry demanded
+eagerly. &ldquo;Let&rsquo;s see the chart.&rdquo;</p>
+<p>It was thrust into his hand. Jerry stared at the intercepting
+lines and then at a map of the district.</p>
+<p>&ldquo;Why, the station seems to be located along the
+shore!&rdquo; he exclaimed. &ldquo;Apparently in one of the
+caves&mdash;Crystal Cave I&rsquo;d judge.&rdquo;</p>
+<p>&ldquo;That&rsquo;s the cave where Louise and I were!&rdquo;
+Penny exclaimed. &ldquo;But we saw no shortwave radio
+apparatus. Only crazy old Skagway who was playing
+a tune on the stalagmites.&rdquo;</p>
+<p>&ldquo;All the same, direction finders don&rsquo;t lie. The
+broadcast came from Crystal Cave! But that doesn&rsquo;t
+mean the station will be there fifteen minutes from
+now.&rdquo;</p>
+<div class="pb" id="Page_113">[113]</div>
+<p>&ldquo;What&rsquo;s to be done?&rdquo; Penny asked. &ldquo;Can&rsquo;t the
+Voice be caught before he has a chance to move his
+portable outfit?&rdquo;</p>
+<p>&ldquo;A message already has been sent to Headquarters.
+Army men should be on their way to the cave now.&rdquo;</p>
+<p>&ldquo;Jerry, we&rsquo;re not far from Crystal Cave ourselves!&rdquo;
+Penny exclaimed, her eyes dancing with
+excitement. &ldquo;Can&rsquo;t we go there too?&rdquo;</p>
+<p>&ldquo;We can and will!&rdquo; Jerry laughed. &ldquo;But if we
+expect to catch our friend, the Voice, there&rsquo;s no time
+to lose. Come along, girls, if you&rsquo;re traveling with
+me.&rdquo;</p>

+<br /><i>AFTERGLOW</i></h2>
+<p>Penny sprawled on the grass beside the dying
+embers of the camp fire. Listlessly, and with very
+bad aim, she hurled acorns at a brown squirrel chattering
+overhead.</p>
+<p>&ldquo;You&rsquo;ve been in a bad mood ever since we got back
+from Crystal Cave,&rdquo; Louise observed, coming out of
+the tent. &ldquo;But why take it out on that poor creature?&rdquo;</p>
+<p>Penny raised herself on an elbow. She scowled and
+did not reply.</p>
+<p>Louise moved over to the fire, seating herself on a
+log beside her chum.</p>
+<p>&ldquo;Oh, brace up,&rdquo; she said, slipping an arm about
+Penny&rsquo;s shoulders. &ldquo;In all my life I&rsquo;ve never seen you
+act so discouraged.&rdquo;</p>
+<p>&ldquo;I feel lower than the worms. Nothing&rsquo;s gone
+right since we came to Sunset Beach.&rdquo;</p>
+<p>&ldquo;On the contrary, I can&rsquo;t see that anything has gone
+so very wrong.&rdquo;</p>
+<div class="pb" id="Page_115">[115]</div>
+<p>&ldquo;Wasn&rsquo;t our trip to the Crystal Cave a bust?&rdquo;
+Penny demanded.</p>
+<p>&ldquo;Well, it wasn&rsquo;t a success.&rdquo;</p>
+<p>Louise smiled wryly at the recollection. With
+Jerry and the Army men, she and Penny had spent
+the afternoon searching various caves along the
+water front. Not a trace had been found of the mysterious
+radio station which so plagued local authorities.
+The search had been a long and exhausting one.
+In the end, though the others kept on, she and Penny
+had been compelled to give up.</p>
+<p>&ldquo;My feet hurt yet from scrambling over the rocks,&rdquo;
+Penny declared. &ldquo;I suppose Jerry and those Army
+officers will keep searching half the night.&rdquo;</p>
+<p>&ldquo;And I&rsquo;ll warrant they never do find the station,&rdquo;
+Louise contributed. &ldquo;This is one mystery I wish you
+had never stumbled into, Penny.&rdquo;</p>
+<p>&ldquo;I&rsquo;m beginning to feel the same way, Lou. This is
+supposed to be a vacation. I&rsquo;d like to see Dad and
+Jerry once in awhile.&rdquo;</p>
+<p>&ldquo;So that&rsquo;s what&rsquo;s bothering you!&rdquo;</p>
+<p>&ldquo;Well, you know Jerry will be here only a few
+days at most,&rdquo; Penny said defensively. &ldquo;I&rsquo;ve barely
+had a chance to say &lsquo;hello&rsquo; to him. Dad&rsquo;s always
+down at the hotel too.&rdquo;</p>
+<p>&ldquo;What you crave seems to be male companionship.&rdquo;</p>
+<div class="pb" id="Page_116">[116]</div>
+<p>Penny tossed a stick of wood on the fire, making
+the sparks fly. &ldquo;I could do with a little,&rdquo; she admitted.
+&ldquo;Life is too dull here.&rdquo;</p>
+<p>&ldquo;Dull?&rdquo; Louise gazed at her chum suspiciously.</p>
+<p>&ldquo;It&rsquo;s no use being surrounded by mystery if one
+can&rsquo;t get into the thick of it. So far all the adventure
+has by-passed us.&rdquo;</p>
+<p>&ldquo;We might stir up a little excitement by looking
+for that package Mrs. Deline buried in the sand.&rdquo;</p>
+<p>&ldquo;Not today,&rdquo; Penny said with a sigh. &ldquo;Too tired.
+Besides, I told Jerry about it and he wasn&rsquo;t much impressed.&rdquo;</p>
+<p>&ldquo;So that&rsquo;s the reason for your gloom,&rdquo; Louise remarked
+wisely. &ldquo;As a detective you don&rsquo;t rate.&rdquo;</p>
+<p>&ldquo;Something like that. Jerry met Mrs. Deline at the
+hotel today and he thought her a very charming
+lady.&rdquo;</p>
+<p>&ldquo;Oh!&rdquo; Louise laughed. &ldquo;No wonder you&rsquo;re all
+smashed to bits!&rdquo;</p>
+<p>Penny got up from the grass and began preparations
+for supper. She peeled a pan of potatoes and
+opened a can of corn.</p>
+<p>&ldquo;We need a bucket of water from the spring,&rdquo; she
+said suggestively. &ldquo;Want to help me carry it?&rdquo;</p>
+<p>&ldquo;I will,&rdquo; Louise agreed without enthusiasm.</p>
+<p>The trail led up a steep path to a rocky ledge from
+which cool spring water gushed out of a steel pipe.
+Penny drank deeply and then hung her tin bucket
+over the outlet to fill.</p>
+<div class="pb" id="Page_117">[117]</div>
+<p>&ldquo;It&rsquo;s starting to get dark,&rdquo; she observed, noticing
+how shadowy the woods had grown. &ldquo;I hope Dad
+returns to camp soon.&rdquo;</p>
+<p>&ldquo;Someone&rsquo;s coming now,&rdquo; Louise remarked as her
+keen ears detected the sound of footsteps on the trail
+below.</p>
+<p>&ldquo;Probably one of the rangers.&rdquo;</p>
+<p>Penny unhooked the water bucket from the pipe,
+and the girls started down the trail, carrying it between
+them. Emerging from among the trees, they
+glimpsed a figure below them. A woman in a dark
+cloak who carried a picnic hamper, was walking rapidly
+up the winding trail.</p>
+<p>Penny stopped so suddenly that she spilled water
+on her sandals.</p>
+<p>&ldquo;Lou, that&rsquo;s Mrs. Deline!&rdquo; she whispered.</p>
+<p>&ldquo;What of it, pet? She&rsquo;s evidently going on a
+picnic.&rdquo;</p>
+<p>&ldquo;At this time of day? And alone?&rdquo;</p>
+<p>&ldquo;Well, that part of it does seem a bit odd.&rdquo;</p>
+<p>Penny pulled her chum into the bushes beside the
+path. Crouching low beside their water bucket,
+they allowed the woman to pass. Looking neither
+to the right nor left, she hastened on up the trail.</p>
+<p>&ldquo;She seems to be in a big hurry,&rdquo; Penny commented,
+coming out of hiding. &ldquo;Now where do you
+suppose she&rsquo;s going?&rdquo;</p>
+<div class="pb" id="Page_118">[118]</div>
+<p>&ldquo;Probably to the cabin. One of your ranger
+friends told me about a rustic place farther up the
+trail. It was built especially for the enjoyment of the
+public.&rdquo;</p>
+<p>&ldquo;But why would Mrs. Deline go there alone?&rdquo;</p>
+<p>&ldquo;Maybe she intends to meet someone.&rdquo;</p>
+<p>&ldquo;Lou, that&rsquo;s probably what she is going to do!&rdquo;
+Penny exclaimed. &ldquo;Let&rsquo;s follow her and find out.&rdquo;</p>
+<p>&ldquo;What about supper?&rdquo;</p>
+<p>&ldquo;Who cares for food?&rdquo; Penny demanded. &ldquo;If Dad
+comes home he can rustle a little for himself. It&rsquo;s
+more important that we follow Mrs. Deline.&rdquo;</p>
+<p>&ldquo;Okay,&rdquo; Louise agreed, &ldquo;only I&rsquo;m in no mood to
+walk very far. Remember, we&rsquo;ve had one wild chase
+today.&rdquo;</p>
+<p>Leaving the water bucket behind the bushes, the
+girls set out in pursuit of Mrs. Deline. Not without
+admiration they acknowledged that the widow was
+a better trail climber than they. Though the hamper
+she carried evidently was heavy, she fairly skimmed
+up the rough trail. Penny and Louise fell farther
+and farther behind.</p>
+<p>&ldquo;She&rsquo;s heading for the cabin all right,&rdquo; Penny
+puffed. &ldquo;Of course she intends to meet someone.
+Otherwise, she&rsquo;d have had her picnic on the beach or
+some place closer to the hotel.&rdquo;</p>
+<div class="pb" id="Page_119">[119]</div>
+<p>A clearing opened up through a gap in the trees.
+Mrs. Deline paused as she came within view of the
+rustic log cabin and gazed carefully about. The girls
+saw her look at her wrist watch.</p>
+<p>&ldquo;She has an appointment with someone,&rdquo; Penny
+declared.</p>
+<p>Mrs. Deline walked to the door of the cabin and
+tested it to make certain that it was unlocked. She
+did not go inside. Instead, she set down the hamper
+and gazed slowly about the clearing. Louise and
+Penny, at the fringe of woods, saw her start as she
+looked directly toward them.</p>
+<p>&ldquo;She&rsquo;s seen us!&rdquo; Louise gasped.</p>
+<p>&ldquo;We&rsquo;ll have to go out and meet her,&rdquo; Penny decided
+instantly. &ldquo;Let&rsquo;s pretend we just happened
+to be coming this way. But we&rsquo;ll stick around and
+see who she&rsquo;s meeting.&rdquo;</p>
+<p>Mrs. Deline stiffened visibly as the girls sauntered
+out of the woods toward her.</p>
+<p>&ldquo;Well, this is a surprise meeting you,&rdquo; she said in
+a tone none too friendly. &ldquo;Is your camp located near
+here?&rdquo;</p>
+<p>&ldquo;Down the trail a short distance,&rdquo; Penny replied,
+thoroughly enjoying the widow&rsquo;s discomfiture.
+&ldquo;Having a picnic?&rdquo;</p>
+<p>&ldquo;Why, yes. I love the outdoors and thought I&rsquo;d
+take a hike this afternoon.&rdquo;</p>
+<p>&ldquo;It&rsquo;s rather late for a picnic,&rdquo; Penny said pointedly.</p>
+<p>&ldquo;It took me longer to get here than I expected.&rdquo;</p>
+<div class="pb" id="Page_120">[120]</div>
+<p>In an effort to discourage her young annoyers,
+Mrs. Deline pushed open the door of the cabin. Before
+she could pick up the hamper, Penny seized it.</p>
+<p>&ldquo;Let me,&rdquo; she said quickly. &ldquo;My how heavy!
+All this food for one person?&rdquo;</p>
+<p>&ldquo;Certainly,&rdquo; Mrs. Deline answered. &ldquo;Who else?&rdquo;</p>
+<p>Penny set the hamper on the table. Deliberately
+she raised the lid. The basket was filled with food,
+enough for a dozen persons, and in the bottom she
+saw a folded wool blanket. Beneath the blanket were
+several bulky garments which she took to be men&rsquo;s
+clothing. Before she could see plainly, Mrs. Deline
+jerked the lid of the hamper into place.</p>
+<p>&ldquo;Please!&rdquo; she said with emphasis.</p>
+<p>&ldquo;I was only trying to be helpful,&rdquo; Penny said, pretending
+to look injured. &ldquo;Don&rsquo;t you want Lou and
+me to dust off the table and spread out the picnic
+things?&rdquo;</p>
+<p>&ldquo;I do not. If you&rsquo;ll excuse me for saying so, I came
+on this picnic to be alone. I enjoy solitude.&rdquo;</p>
+<p>&ldquo;But it&rsquo;s getting dark,&rdquo; Penny argued. &ldquo;We
+wouldn&rsquo;t think of deserting you. The cabin has no
+light.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t mind the dark. Anyway, I brought candles.
+I really prefer to be alone.&rdquo;</p>
+<div class="pb" id="Page_121">[121]</div>
+<p>Thus dismissed, Louise started to leave. Penny
+lingered, trying to think of some excuse. Just then,
+from somewhere in the woods, she heard a shrill
+whistle unlike any bird call.</p>
+<p>&ldquo;What was that?&rdquo; she asked alertly.</p>
+<p>&ldquo;I heard nothing,&rdquo; said Mrs. Deline.</p>
+<p>Nevertheless, a moment later the woman sauntered
+to an open cabin window. Deliberately she turned
+her back to the girls, trying to block their view.
+Quickly she raised and lowered her handkerchief.</p>
+<p>The movement was deftly executed, but swift
+though it was, Penny saw and understood. Mrs.
+Deline had signaled to an unseen person beyond the
+fringe of trees!</p>
+<div class="pb" id="Page_122">[122]</div>
+<h2 id="c16"><span class="small">CHAPTER</span>
+<br /><span class="large">16</span>
+<br /><i>SUSPICION</i></h2>
+<p>Penny moved swiftly to the open cabin door,
+gazing toward the darkening woods. No one was
+visible amid the shadows. Yet she was certain that
+Mrs. Deline had signaled to someone lurking among
+the trees.</p>
+<p>The widow had turned from the window to unfasten
+the lid of the picnic hamper.</p>
+<p>&ldquo;Since you girls are here you may as well stay and
+share my supper,&rdquo; she said without warmth. &ldquo;There&rsquo;s
+enough food for all.&rdquo;</p>
+<p>Louise&rsquo;s chin tilted proudly. The invitation was
+grudgingly given, and she meant to decline. Penny
+forestalled her by saying:</p>
+<p>&ldquo;How nice of you, Mrs. Deline! Of course we&rsquo;ll
+be delighted to remain.&rdquo;</p>
+<p>Mrs. Deline made no reply, though obviously she
+had not expected an acceptance. Irritably she laid
+out the picnic dishes&mdash;sandwiches, a salad, cake,
+cookies, and fruit&mdash;all carefully prepared and cooked
+at the hotel kitchen.</p>
+<div class="pb" id="Page_123">[123]</div>
+<p>&ldquo;You certainly did bring plenty of food for one
+person,&rdquo; Penny commented, helping herself to a
+chicken sandwich. &ldquo;Isn&rsquo;t that clothing in the bottom
+of the basket?&rdquo;</p>
+<p>&ldquo;Only a blanket.&rdquo; Mrs. Deline closed the lid
+firmly. &ldquo;I thought I might need it if I should sit on
+the damp ground.&rdquo;</p>
+<p>Hungry as bears, Penny and Louise did not try
+to curb their healthy, young appetites. Mrs. Deline,
+on the other hand, scarcely nibbled at the food. Several
+times she arose and paced nervously to the window.</p>
+<p>&ldquo;It&rsquo;s growing dark and I should return to the
+hotel,&rdquo; she said the instant the girls had finished eating.
+&ldquo;I&rsquo;ll not bother to repack the lunch basket.&rdquo;</p>
+<p>&ldquo;Oh, we&rsquo;ll help you pick up everything,&rdquo; Penny
+offered.</p>
+<p>&ldquo;Please don&rsquo;t bother. I&rsquo;ll merely pay the hotel
+for the basket.&rdquo;</p>
+<p>Penny was convinced that Mrs. Deline deliberately
+intended to leave the hamper behind. Despite the
+deep inroads she and Louise had made, considerable
+food remained. It occurred to her that the widow
+hoped to leave what remained so that the person hiding
+in the woods might come to the cabin for it after
+the party had gone.</p>
+<div class="pb" id="Page_124">[124]</div>
+<p>&ldquo;I can&rsquo;t be bothered with a heavy basket,&rdquo; Mrs.
+Deline said impatiently. &ldquo;We&rsquo;ll just leave it on the
+table.&rdquo;</p>
+<p>&ldquo;Oh, the rangers wouldn&rsquo;t like to have us leave
+food here,&rdquo; Penny protested. &ldquo;It will only take a
+minute to clean up everything.&rdquo;</p>
+<p>Disregarding Mrs. Deline&rsquo;s order, she began to repack
+the remains of the lunch.</p>
+<p>&ldquo;But I don&rsquo;t wish to carry the basket all the way
+to the hotel!&rdquo;</p>
+<p>&ldquo;Louise and I will help you.&rdquo;</p>
+<p>Tossing her head, Mrs. Deline walked out of the
+cabin, allowing the door to slam behind her. Louise
+and Penny finished packing the lunch and hastened
+down the trail in pursuit.</p>
+<p>&ldquo;Maybe we shouldn&rsquo;t cross her so,&rdquo; Louise whispered
+uneasily. &ldquo;I think she intended to meet someone
+here!&rdquo;</p>
+<p>&ldquo;I&rsquo;m sure of it,&rdquo; agreed Penny. &ldquo;We spiked her
+little plan. I have an idea who she intended to meet
+too!&rdquo;</p>
+<p>&ldquo;Who?&rdquo;</p>
+<p>Penny could not answer, for by this time she and
+Louise were practically at Mrs. Deline&rsquo;s heels. The
+widow was walking as fast as she could.</p>
+<p>&ldquo;You&rsquo;ll have to keep the basket,&rdquo; she told the girls
+irritably. &ldquo;I&rsquo;m sure I&rsquo;ll never carry it back to the
+hotel.&rdquo;</p>
+<div class="pb" id="Page_125">[125]</div>
+<p>All the way to the Parker camp Mrs. Deline ignored
+Penny and Louise. And as they bade her
+goodbye, she barely responded.</p>
+<p>&ldquo;Can&rsquo;t we drive you down to the hotel in the car?&rdquo;
+Penny offered, feeling slightly ashamed of her actions.</p>
+<p>&ldquo;Thank you, no,&rdquo; the widow answered icily.
+&ldquo;You&rsquo;ve done quite enough for one day.&rdquo; She vanished
+down the darkening road.</p>
+<p>After Mrs. Deline was beyond view, the girls retraced
+their way to the spring for the water bucket.
+As they approached, they thought for a moment that
+they heard retreating footsteps. The realization that
+they were alone in the woods, made them a bit nervous.
+Hurriedly they recovered the bucket and carried
+it to camp.</p>
+<p>&ldquo;Now tell me what you think, Penny!&rdquo; Louise
+commanded when they were inside the tent.</p>
+<p>&ldquo;Why, it&rsquo;s clear as crystal.&rdquo; Penny struck a match
+to the wick of the gasoline lantern and hung it on a
+hook of the tent pole. &ldquo;Mrs. Deline went to the
+cabin intending to meet someone. She carried extra
+food, a blanket, and if I&rsquo;m not mistaken, clothing for
+a man.&rdquo;</p>
+<p>&ldquo;You thought she signaled from the window?&rdquo;</p>
+<p>&ldquo;I&rsquo;m sure she did, Lou. She warned the person,
+whoever he was, not to approach. She hoped by
+leaving the basket behind to get it into his hands after
+we&rsquo;d gone.&rdquo;</p>
+<div class="pb" id="Page_126">[126]</div>
+<p>&ldquo;You thwarted her in that.&rdquo;</p>
+<p>&ldquo;We did together,&rdquo; Penny chuckled. Her face
+suddenly became sober. &ldquo;Lou&mdash;&rdquo;</p>
+<p>&ldquo;Yes?&rdquo;</p>
+<p>&ldquo;It just occurred to me! Maybe the man she intended
+to meet was the same fellow who stole food
+from our camp.&rdquo;</p>
+<p>&ldquo;That&rsquo;s possible. But why should Mrs. Deline be
+interested in a common tramp?&rdquo;</p>
+<p>&ldquo;How do we know that fellow was a tramp?&rdquo;
+Penny speculated. &ldquo;Jerry told us about a young soldier
+that had escaped from a Canadian prison camp.
+Mrs. Deline may be trying to help him by supplying
+food and heavy clothing!&rdquo;</p>
+<p>&ldquo;As usual, Penny, aren&rsquo;t you leaping to hasty conclusions?&rdquo;</p>
+<p>&ldquo;Maybe I am, but everything fits in beautifully.
+I&rsquo;ve thought from the first that Mrs. Deline was nothing
+less than a spy or an international crook.&rdquo;</p>
+<p>&ldquo;You&rsquo;ve aired that theory before,&rdquo; Louise said,
+stretching out on the cot. &ldquo;Wonder when your
+father will get here?&rdquo;</p>
+<p>&ldquo;I wish he would come,&rdquo; Penny replied, glancing
+anxiously toward the road. &ldquo;At least I have one consolation.&rdquo;</p>
+<p>&ldquo;What&rsquo;s that?&rdquo;</p>
+<div class="pb" id="Page_127">[127]</div>
+<p>&ldquo;I know he&rsquo;s not with Mrs. Deline. Oh, Lou,
+think how horrible it would be to have a spy for a
+stepmother!&rdquo;</p>
+<p>&ldquo;It would be something different anyhow,&rdquo; Louise
+chuckled. &ldquo;Want to listen to the radio awhile?&rdquo;</p>
+<p>&ldquo;Okay,&rdquo; Penny agreed, &ldquo;maybe we can tune in
+that outlaw station. It&rsquo;s about time for the regular
+nightly broadcast.&rdquo;</p>
+<p>Closing themselves into the car, the girls tried without
+success to get the outlaw shortwave station.
+Tuning instead to a dance orchestra, they discussed
+the day&rsquo;s happenings and made elaborate plans for
+the morrow.</p>
+<p>&ldquo;I&rsquo;m really going to work,&rdquo; Penny announced
+grimly. &ldquo;No Mrs. Deline ever will outwit me! Our
+first job must be to find that package she buried in
+the sand.&rdquo;</p>
+<p>&ldquo;And what of the person hiding in the woods?&rdquo;</p>
+<p>&ldquo;The rangers ought to take over that part.&rdquo; Penny
+peered out through the car window at the dark
+woods which hemmed in the camp. &ldquo;Somehow,&rdquo; she
+admitted, &ldquo;I don&rsquo;t like the idea of being here at night.
+I&rsquo;m not exactly afraid, but&mdash;&rdquo;</p>
+<p>&ldquo;Listen!&rdquo; Louise ordered sharply, &ldquo;Someone&rsquo;s
+coming!&rdquo;</p>
+<p>Penny snapped off the radio. Tensely, the girls
+watched the road. The next instant they relaxed,
+for it was Mr. Parker who trudged wearily up the
+slope. Seeing Penny and Louise in the car, he came
+over to apologize for being so late.</p>
+<div class="pb" id="Page_128">[128]</div>
+<p>&ldquo;I&rsquo;ve been with Jerry for the past two hours,&rdquo; he
+explained. &ldquo;Time went faster than I realized.&rdquo;</p>
+<p>&ldquo;Any news?&rdquo; Penny asked eagerly.</p>
+<p>&ldquo;Not about the radio station if that&rsquo;s what you
+mean. The fellow got away with his portable outfit
+slick as a whistle.&rdquo;</p>
+<p>&ldquo;The authorities have no idea who the man is,
+Dad?&rdquo;</p>
+<p>&ldquo;Not the slightest. So far they&rsquo;ve not been able
+to break the code he uses either. But in time they&rsquo;ll
+get him.&rdquo;</p>
+<p>Having gleaned what information they could from
+Mr. Parker, the girls related their own adventure. As
+they fully expected, he made light of the episode at
+the cabin.</p>
+<p>&ldquo;Why should Mrs. Deline expect to meet anyone
+there?&rdquo; he argued. &ldquo;Penny, I&rsquo;m afraid you don&rsquo;t
+understand her and misinterpret her actions.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t understand her, that&rsquo;s certain.&rdquo;</p>
+<p>&ldquo;As to a man loitering about the camp,&rdquo; Mr. Parker
+resumed, &ldquo;I&rsquo;ve been worried about that ever since
+food was stolen. As I must be gone so much of the
+time, why wouldn&rsquo;t it be better for us to move to
+the hotel?&rdquo;</p>
+<p>Penny stiffened for an argument, and then suddenly
+changed her mind.</p>
+<div class="pb" id="Page_129">[129]</div>
+<p>&ldquo;All right, Dad,&rdquo; she astonished him by saying,
+&ldquo;as far as I&rsquo;m concerned, we can move tomorrow.
+I&rsquo;ve had enough of the lonesome life.&rdquo;</p>
+<p>&ldquo;Why, that&rsquo;s fine!&rdquo; Mr. Parker said heartily.
+&ldquo;Splendid!&rdquo;</p>
+<p>After he had moved on, to sit for awhile by the
+dying embers of the fire, Louise remarked to Penny
+that explanations were in order.</p>
+<p>&ldquo;How come you&rsquo;re ready to desert the rough and
+rugged life?&rdquo; she demanded. &ldquo;At first you were
+dead set against moving into the hotel.&rdquo;</p>
+<p>Penny carefully raised the car window so that her
+father would not overhear.</p>
+<p>&ldquo;I believe in fighting the Enemy on his own territory,&rdquo;
+she explained elaborately. &ldquo;Mrs. Deline will
+bear watching. I intend to devote all my waking
+hours to the cause.&rdquo;</p>
+<p>&ldquo;So Jerry has nothing to do with it?&rdquo;</p>
+<p>&ldquo;Jerry?&rdquo;</p>
+<p>&ldquo;You wouldn&rsquo;t want to move to the hotel so you&rsquo;d
+see more of him?&rdquo;</p>
+<p>&ldquo;What an idea!&rdquo; Penny scoffed. &ldquo;Whoever
+thought of such a thing!&rdquo;</p>
+<p>&ldquo;You did or I&rsquo;m no mind reader.&rdquo;</p>
+<p>&ldquo;Well, it may have crossed my mind,&rdquo; Penny acknowledged
+with a giggle. &ldquo;In fact, I can see quite
+a few advantages to hotel life. With luck we&rsquo;ll yet
+make something of this vacation!&rdquo;</p>
+<div class="pb" id="Page_130">[130]</div>
+<h2 id="c17"><span class="small">CHAPTER</span>
+<br /><span class="large">17</span>
+<br /><i>VISITORS NOT PERMITTED</i></h2>
+<p>Penny stood before the mirror in the hotel
+room and struggled to coax a little curl into her damp
+hair. She and Louise had spent two hours splashing
+in the surf that morning. The salt water had tightened
+their skins and produced discouraging results
+with their tresses.</p>
+<p>&ldquo;This place does have it over a forest camp,&rdquo; Penny
+said, gazing about the comfortably furnished room
+she shared with Louise. Her father&rsquo;s room was three
+doors down the hall. &ldquo;A shower bath, no meals to
+cook, no dishes to wash, and the sea at one&rsquo;s elbow.&rdquo;</p>
+<p>&ldquo;I like it better,&rdquo; replied Louise. She had curled up
+kitten fashion on the bed and was making deep inroads
+into a box of chocolates. &ldquo;So far though, we&rsquo;ve
+not done much fancy sleuthing.&rdquo;</p>
+<p>&ldquo;We&rsquo;ve only been here a few hours. Where do
+you suppose Mrs. Deline keeps herself?&rdquo;</p>
+<div class="pb" id="Page_131">[131]</div>
+<p>&ldquo;In her room no doubt. Why do you worry about
+her so much, Penny?&rdquo;</p>
+<p>Penny twisted a few ringlets over her finger and
+abandoned the project as hopeless. &ldquo;Lou, you know
+all the prize answers without asking me,&rdquo; she said.
+&ldquo;I&rsquo;ve told you a dozen times why I distrust that
+woman.&rdquo;</p>
+<p>&ldquo;Doesn&rsquo;t it all simmer down to one thing? You&rsquo;re
+jealous as a green-eyed cat!&rdquo;</p>
+<p>&ldquo;Maybe I do dislike her,&rdquo; Penny grinned. &ldquo;On
+second thought, I&rsquo;m sure of it! But facts are facts
+and have nothing to do with my personal feelings. In
+the first place, didn&rsquo;t she get Dad to bring her with
+us to Sunset Beach?&rdquo;</p>
+<p>&ldquo;But what does that prove? She has no car of her
+own and the trains are so crowded.&rdquo;</p>
+<p>&ldquo;I think she knew that Dad was coming here to
+try to dig up a story about the outlaw radio station,&rdquo;
+Penny went on, unruffled. &ldquo;She&rsquo;s probably pumped
+him of information.&rdquo;</p>
+<p>&ldquo;Your father knows how to look after himself.&rdquo;</p>
+<p>&ldquo;That&rsquo;s what <i>he</i> thinks!&rdquo; Penny muttered. &ldquo;I
+wouldn&rsquo;t place any wagers on it myself. Why, he&rsquo;s
+been as blind as a bat.&rdquo;</p>
+<p>&ldquo;I&rsquo;m afraid you see enough for two or three people,&rdquo;
+Louise chuckled.</p>
+<p>&ldquo;I told you, didn&rsquo;t I, how that vampire tried to
+steal our car while we were on our way here?&rdquo;</p>
+<div class="pb" id="Page_132">[132]</div>
+<p>&ldquo;Two or three times, darling.&rdquo;</p>
+<p>&ldquo;Well, it would bear repeating. I think she intended
+to meet someone that night&mdash;perhaps the
+same person who was hiding in the woods!&rdquo;</p>
+<p>Louise, methodically eating chocolates, mulled over
+the possibility.</p>
+<p>&ldquo;Jerry told us that an escaped flier from a Canadian
+prison camp may be hiding somewhere near here,&rdquo;
+Penny resumed, wandering to the window. &ldquo;Perhaps
+Mrs. Deline is trying to help him!&rdquo;</p>
+<p>&ldquo;You have a new theory every minute,&rdquo; Louise
+yawned. &ldquo;Why not think up one and stick to it?&rdquo;</p>
+<p>Penny did not answer for at that moment she observed
+Jerry Livingston leaving the veranda of the
+hotel.</p>
+<p>&ldquo;Come on, Lou!&rdquo; she cried, jerking her chum off
+the bed. &ldquo;I want to see Jerry before he escapes!&rdquo;</p>
+<p>&ldquo;Talk about Mrs. Deline pursuing your defenseless
+father!&rdquo; Louise protested as she was pulled down the
+hall to the elevator. &ldquo;Her tactics at least are more
+subtle than yours!&rdquo;</p>
+<p>&ldquo;This is different,&rdquo; Penny retorted shamelessly.
+&ldquo;Jerry and I are old friends.&rdquo;</p>
+<p>Swinging through the revolving doors of the hotel,
+the girls raced after Jerry. Breathless from running,
+they finally overtook him far down the boardwalk.</p>
+<p>&ldquo;Why, hello,&rdquo; he greeted them with a broad smile.
+&ldquo;I hear you&rsquo;ve moved into the hotel.&rdquo;</p>
+<div class="pb" id="Page_133">[133]</div>
+<p>&ldquo;Lock, stock and barrel,&rdquo; Penny laughed. &ldquo;We
+want to be in the thick of things. Any news about
+the radio station?&rdquo;</p>
+<p>&ldquo;Nothing I can report, I&rsquo;m on my way now to
+Intercept Headquarters.&rdquo;</p>
+<p>&ldquo;Did you see Dad this morning?&rdquo;</p>
+<p>&ldquo;Only for a few minutes. He&rsquo;s doing a little special
+work for me.&rdquo;</p>
+<p>&ldquo;At least I&rsquo;m glad it&rsquo;s for you and not Mrs. Deline,&rdquo;
+Penny said stiffly. &ldquo;Jerry, there are some things you
+should know about that woman.&rdquo;</p>
+<p>&ldquo;Suppose you unburden your heart,&rdquo; Jerry invited,
+seating himself on a sand dune. &ldquo;I have about ten
+minutes to listen.&rdquo;</p>
+<p>&ldquo;Don&rsquo;t encourage her,&rdquo; sighed Louise. &ldquo;She&rsquo;s
+slightly cracked on the subject, you know.&rdquo;</p>
+<p>&ldquo;Nevertheless, Penny has ideas at times,&rdquo; Jerry paid
+her tribute. &ldquo;Shoot!&rdquo;</p>
+<p>Talking like a whirlwind, Penny delved deeply
+into the subject of Mrs. Deline. She repeated how
+the widow had buried a package in the sand, but it
+was not until the episode of the cabin was described
+that Jerry really seemed interested.</p>
+<p>&ldquo;Penny, at first I didn&rsquo;t take your Mrs. Deline talk
+very seriously,&rdquo; he admitted. &ldquo;Perhaps you have
+something after all!&rdquo;</p>
+<p>&ldquo;I&rsquo;m sure of it, Jerry!&rdquo;</p>
+<p>&ldquo;Have you reported to the park rangers?&rdquo;</p>
+<div class="pb" id="Page_134">[134]</div>
+<p>&ldquo;Dad may have seen them, I&rsquo;m not sure. We left
+camp in a big rush.&rdquo;</p>
+<p>&ldquo;Then I&rsquo;ll take care of that, Penny. We&rsquo;ll have
+the park searched again and try to find that fellow!&rdquo;</p>
+<p>&ldquo;Then you do believe he&rsquo;s the escaped flier!&rdquo;
+Penny exclaimed.</p>
+<p>&ldquo;Probably not,&rdquo; was Jerry&rsquo;s discouraging reply.
+&ldquo;Nevertheless, we can&rsquo;t afford to overlook any possibility.&rdquo;</p>
+<p>&ldquo;What about the package in the sand?&rdquo;</p>
+<p>&ldquo;You remember where it was buried?&rdquo;</p>
+<p>&ldquo;Approximately.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll not have time to go with you now,&rdquo; Jerry said,
+looking at his wrist watch.</p>
+<p>&ldquo;Louise and I haven&rsquo;t much to do this morning.
+We&rsquo;ll be glad to search.&rdquo;</p>
+<p>&ldquo;Go ahead,&rdquo; Jerry urged. &ldquo;If you fail then I can
+take over. The important thing is not to tip off your
+hand. Don&rsquo;t let anyone suspect what you&rsquo;re about.&rdquo;</p>
+<p>Penny and Louise nodded soberly. They felt
+rather important to have been assigned a definite task.</p>
+<p>&ldquo;Report to me as soon as you find that package,&rdquo;
+Jerry urged as he started on. &ldquo;It may contain something
+of vital importance. It may not. We&rsquo;ll withhold
+judgment until we have the facts.&rdquo;</p>
+<p>Left to themselves, the girls lost not a moment in
+hastening to the section of beach where Mrs. Deline
+had been seen to bury the package.</p>
+<div class="pb" id="Page_135">[135]</div>
+<p>&ldquo;Now just where was it?&rdquo; Penny asked, gazing
+about the deserted dunes. &ldquo;What became of our
+marker?&rdquo;</p>
+<p>&ldquo;We left a stick to show the exact spot.&rdquo;</p>
+<p>&ldquo;Not a sign of it now. What wretched luck!&rdquo;</p>
+<p>Though the girls knew the general locality where
+the package had been buried, all of the dunes looked
+discouragingly alike. Not a footprint remained to
+guide them.</p>
+<p>&ldquo;I&rsquo;ll bet a cent Mrs. Deline came back here and
+removed that stick!&rdquo; Penny declared. &ldquo;Maybe she
+dug up the package too!&rdquo;</p>
+<p>&ldquo;Anyone could have taken the stick. Why do you
+think she did it?&rdquo;</p>
+<p>&ldquo;Because she watched us digging for the package.
+Well, let&rsquo;s look for it anyhow.&rdquo;</p>
+<p>With none too much enthusiasm, the girls set to
+work. The tide was much lower than upon their last
+visit and the shoreline did not look the same. Nor
+could they agree within forty feet of the right place
+to dig.</p>
+<p>&ldquo;You try one dune, and I&rsquo;ll work on another,&rdquo;
+Penny offered as a compromise.</p>
+<p>An hour of unavailing work found the pair too discouraged
+to keep on digging.</p>
+<p>&ldquo;If this is the right place, Mrs. Deline or someone
+has removed the package,&rdquo; Penny declared, sinking
+back on her heels.</p>
+<div class="pb" id="Page_136">[136]</div>
+<p>&ldquo;We may as well give up,&rdquo; Louise added wearily.</p>
+<p>Penny slid down the dune and emptied sand from
+her shoes.</p>
+<p>&ldquo;There should be an easy way to beat Mrs. Deline
+at her own little game,&rdquo; she remarked thoughtfully.
+&ldquo;For instance, why does she always wear that jade
+green charm?&rdquo;</p>
+<p>&ldquo;Because she likes it I&rsquo;d imagine.&rdquo;</p>
+<p>&ldquo;But wouldn&rsquo;t you think she&rsquo;d take it off at night?&rdquo;</p>
+<p>&ldquo;Perhaps she does, Penny.&rdquo;</p>
+<p>&ldquo;Not the night I was with her. I distinctly gained
+the impression that there was something about it she
+was afraid I&rsquo;d see.&rdquo;</p>
+<p>&ldquo;A message contained inside?&rdquo;</p>
+<p>&ldquo;That&rsquo;s been my theory from the first, Lou. Now
+if only we could lay our hands on the charm&mdash;&rdquo;</p>
+<p>&ldquo;Finding the package would be a lot easier. We
+can&rsquo;t waylay the woman and take the jade elephant
+by force. Or can we?&rdquo;</p>
+<p>&ldquo;No,&rdquo; Penny agreed reluctantly, &ldquo;I don&rsquo;t think
+Dad would like that. And there&rsquo;s always the possibility
+I might be wrong.&rdquo;</p>
+<p>&ldquo;The probability, you mean,&rdquo; corrected Louise.</p>
+<p>Penny retied her shoes and glanced toward the
+hotel. Far up the beach she saw Mrs. Deline, and
+the widow was walking slowly toward the sand
+dunes.</p>
+<div class="pb" id="Page_137">[137]</div>
+<p>&ldquo;Duck!&rdquo; Penny ordered, rolling over one of the
+high ridges. &ldquo;We don&rsquo;t want her to see us here. She&rsquo;ll
+suspect what we&rsquo;ve been up to.&rdquo;</p>
+<p>Louise crouched behind the dune with her chum,
+though she complained that she felt silly doing it.
+Apparently, Mrs. Deline had not seen the girls. She
+came steadily on.</p>
+<p>Drawing close, she peered directly at the dune
+where the girls had taken refuge. For a second they
+feared that she had seen them. But she passed on
+without another glance.</p>
+<p>&ldquo;It looks to me as though she&rsquo;s on her way to the
+lighthouse again,&rdquo; Penny remarked after Mrs. Deline
+was far down the beach. &ldquo;Wonder why she goes
+there so often?&rdquo;</p>
+<p>&ldquo;I thought visitors weren&rsquo;t allowed.&rdquo;</p>
+<p>&ldquo;According to the rules they&rsquo;re not.&rdquo;</p>
+<p>From behind the dune, the girls kept watch of the
+widow. Presently they saw her climb the steps of
+the lighthouse and disappear into the interior.</p>
+<p>&ldquo;Well, that settles it!&rdquo; Penny exclaimed indignantly.</p>
+<p>&ldquo;Settles what?&rdquo; Louise straightened up, brushing
+sand from her skirt.</p>
+<p>&ldquo;If Mrs. Deline can get into that lighthouse, so
+can I. We&rsquo;ll make an issue of it!&rdquo;</p>
+<p>&ldquo;Not today,&rdquo; said Louise dubiously.</p>
+<div class="pb" id="Page_138">[138]</div>
+<p>&ldquo;Right now!&rdquo; Penny corrected, starting down the
+beach. &ldquo;That lighthouse is government property,
+and as citizens we have certain rights. Let&rsquo;s assert
+them and see what happens!&rdquo;</p>
+<div class="pb" id="Page_139">[139]</div>
+<h2 id="c18"><span class="small">CHAPTER</span>
+<br /><span class="large">18</span>
+<br /><i>INSIDE THE LIGHTHOUSE</i></h2>
+<p>Unchallenged, Penny and Louise reached
+the base of the lighthouse. But as they slowly
+climbed the iron stairs, their courage fast slipped
+away.</p>
+<p>&ldquo;What will we say to the keeper?&rdquo; Louise faltered.
+&ldquo;I&rsquo;ve even forgotten his name.&rdquo;</p>
+<p>&ldquo;I haven&rsquo;t,&rdquo; said Penny. &ldquo;It&rsquo;s Jim McCoy. If
+Mrs. Deline is allowed inside the tower, shouldn&rsquo;t
+we have the same privileges?&rdquo;</p>
+<p>&ldquo;She&rsquo;s a personal friend.&rdquo;</p>
+<p>&ldquo;That should make no difference,&rdquo; Penny argued.
+&ldquo;This is government property.&rdquo;</p>
+<p>&ldquo;Let&rsquo;s not do it,&rdquo; Louise pleaded, holding back.</p>
+<p>Having proceeded so far. Penny was in no mood to
+retreat. Quickly, lest she too lose her courage, she
+rapped hard on the tower door.</p>
+<div class="pb" id="Page_140">[140]</div>
+<p>Minutes elapsed. Then the heavy oak door swung
+back and Jim McCoy, the burly keeper, peered out
+at the girls. His bushy brows drew together in an
+angry scowl.</p>
+<p>&ldquo;You here again!&rdquo; he exclaimed.</p>
+<p>&ldquo;Yes,&rdquo; said Penny, making the word crisp and firm.</p>
+<p>&ldquo;I&rsquo;ll have to report you if you keep pestering me,&rdquo;
+the keeper scolded. &ldquo;How many times have I told
+you no visitors are allowed?&rdquo;</p>
+<p>&ldquo;But you don&rsquo;t treat everyone the same!&rdquo; Penny
+remonstrated. &ldquo;Mrs. Deline just came here.&rdquo;</p>
+<p>&ldquo;Mrs. Deline? Who&rsquo;s she?&rdquo;</p>
+<p>&ldquo;Why, a woman who stays at the hotel. She came
+through this door not five minutes ago!&rdquo;</p>
+<p>&ldquo;You must have imagined it. I&rsquo;ve had no visitors.&rdquo;</p>
+<p>Penny&rsquo;s silence said more plainly than words that
+she did not believe the keeper.</p>
+<p>&ldquo;So you think I&rsquo;m lying, eh?&rdquo; he demanded unpleasantly.
+&ldquo;Okay, come in and see for yourselves.
+I&rsquo;m breaking a rule to invite you into the tower, but
+maybe then you&rsquo;ll be satisfied and quite bothering me.
+We have work to do here, you know.&rdquo;</p>
+<p>The keeper stepped aside so that the girls might
+enter.</p>
+<p>&ldquo;My living quarters,&rdquo; he said curtly. &ldquo;You see,
+I have no visitors.&rdquo;</p>
+<div class="pb" id="Page_141">[141]</div>
+<p>Decidedly ill at ease, the girls gazed about the little
+circular room. The walls were lined with built-in
+cupboards. Nearly all of the furniture had been
+made with a view to conserving space. As Mr.
+McCoy had said, there were no visitors&mdash;no evidence
+that Mrs. Deline ever had been there.</p>
+<p>&ldquo;Are you satisfied?&rdquo; the keeper demanded unpleasantly.</p>
+<p>&ldquo;But we were sure Mrs. Deline came here,&rdquo; Penny
+stammered.</p>
+<p>&ldquo;There&rsquo;s been no one today except early this morning
+when a government inspector paid me a visit.&rdquo;</p>
+<p>Penny did not believe the man but she deemed it
+wise to appear to do so.</p>
+<p>&ldquo;I&rsquo;m sorry,&rdquo; she apologized. &ldquo;I guess we have
+made nuisances of ourselves.&rdquo;</p>
+<p>&ldquo;That&rsquo;s all right,&rdquo; the keeper said in a less unfriendly
+tone. &ldquo;Kids are kids. Now that you&rsquo;re
+here, look around a bit.&rdquo;</p>
+<p>&ldquo;Oh, thank you,&rdquo; Louise replied gratefully. &ldquo;I&rsquo;ve
+always wanted to see the inside of a lighthouse.&rdquo;</p>
+<p>&ldquo;I have some work to do,&rdquo; Mr. McCoy announced.
+&ldquo;The light&rsquo;s not been operating right and I&rsquo;m trying
+to get the mechanism adjusted. I&rsquo;ll be back.&rdquo;</p>
+<p>He went out, allowing the door to slam hard.</p>
+<p>The girls surveyed their surroundings with keen
+interest. On a table near the window there was a
+shortwave radio. A circular couch occupied another
+curving corner of the room.</p>
+<p>&ldquo;What became of Mrs. Deline?&rdquo; Penny whispered.
+&ldquo;She certainly came here.&rdquo;</p>
+<div class="pb" id="Page_142">[142]</div>
+<p>&ldquo;Of course she did! We saw her plain as day!&rdquo;</p>
+<p>&ldquo;She must be somewhere in the tower. Probably
+there&rsquo;s a room above this one.&rdquo;</p>
+<p>Penny tiptoed to the door and tried to open it.
+To her surprise and chagrin, it would not budge.</p>
+<p>&ldquo;My Great Aunt!&rdquo; she whispered. &ldquo;We&rsquo;re locked
+in!&rdquo;</p>
+<p>&ldquo;Maybe the door&rsquo;s just stuck.&rdquo; Louise strode
+across the room to help Penny. Both of them tried
+without success to open it.</p>
+<p>&ldquo;Let&rsquo;s shout and pound!&rdquo; Louise suggested.</p>
+<p>&ldquo;No, wait! I think we&rsquo;ve been locked in here on
+purpose.&rdquo;</p>
+<p>&ldquo;Oh, Penny!&rdquo;</p>
+<p>&ldquo;Now don&rsquo;t get nervous. The keeper&rsquo;s no fool.
+He&rsquo;ll have to let us out.&rdquo;</p>
+<p>&ldquo;But why would he lock us in?&rdquo;</p>
+<p>&ldquo;Because he&rsquo;s provoked at us for one reason, Lou.
+Another, something&rsquo;s going on here that he doesn&rsquo;t
+want us to know about. He and Mrs. Deline may
+be having a t&ecirc;te-&agrave;-t&ecirc;te in the room above.&rdquo;</p>
+<p>&ldquo;Then let&rsquo;s listen. Maybe we can overhear their
+conversation.&rdquo;</p>
+<p>Penny nodded and fell silent. Though the girls
+listened for a long while, no sound reached their ears.</p>
+<p>&ldquo;This is a nice situation!&rdquo; Louise fumed. &ldquo;I think
+the door locked itself. We ought to shout for help.&rdquo;</p>
+<p>&ldquo;Goose, a door doesn&rsquo;t lock itself.&rdquo;</p>
+<div class="pb" id="Page_143">[143]</div>
+<p>&ldquo;This one might have a trick catch.&rdquo;</p>
+<p>&ldquo;It was Mr. Jim McCoy who accomplished the
+trick,&rdquo; Penny said. &ldquo;Listen! Someone&rsquo;s coming
+now.&rdquo;</p>
+<p>Plainly the girls could hear footsteps on the iron
+balcony outside the door. A moment later they were
+able to distinguish a murmur of men&rsquo;s voices. The
+footsteps moved on and a moment later they heard
+a door close overhead.</p>
+<p>&ldquo;Another visitor!&rdquo; Penny announced. &ldquo;Did you
+hear what was said, Lou?&rdquo;</p>
+<p>&ldquo;Couldn&rsquo;t make out a word.&rdquo;</p>
+<p>&ldquo;Nor could I. But that voice sounded familiar.
+I&rsquo;m sure I&rsquo;ve heard it somewhere.&rdquo;</p>
+<p>&ldquo;I had the same feeling, Penny.&rdquo;</p>
+<p>The girls listened intently, hoping to overhear conversation
+on the floor above. However, the walls of
+the lighthouse were so thick that not a word reached
+them. Now and then they thought they heard Mrs.
+Deline&rsquo;s high pitched voice.</p>
+<p>&ldquo;Louise, it&rsquo;s just come to me!&rdquo; Penny whispered
+a moment later. &ldquo;I believe Mr. McCoy&rsquo;s visitor may
+be George Emory!&rdquo;</p>
+<p>&ldquo;The voice did sound a little like his. But why
+would he come here?&rdquo;</p>
+<p>&ldquo;Maybe we&rsquo;ve under-rated George Emory. Why,
+all this time he may have been trying to get information
+from us.&rdquo;</p>
+<div class="pb" id="Page_144">[144]</div>
+<p>&ldquo;He did ask us quite a few questions, particularly
+about your father.&rdquo;</p>
+<p>&ldquo;And he seemed to know a lot about that outlaw
+radio station, Lou. Maybe he tried to throw us off
+the track by suggesting that we watch old Jake Skagway.&rdquo;</p>
+<p>&ldquo;We certainly fell for it, Penny.&rdquo;</p>
+<p>&ldquo;We did, if you assume that George Emory is upstairs
+having a conference with Mrs. Deline and the
+lighthouse keeper. But we&rsquo;re not sure.&rdquo;</p>
+<p>&ldquo;No, we&rsquo;re not, Penny. One easily can be mistaken
+in voices.&rdquo;</p>
+<p>Determined to hear more, Penny cautiously
+climbed up on the radio table, so that her head and
+ear were close to the ceiling.</p>
+<p>&ldquo;Can you make out anything?&rdquo; Louise whispered.</p>
+<p>Penny shook her head in disgust. After a few
+minutes she dropped lightly down from the table.</p>
+<p>&ldquo;Walls are too thick,&rdquo; she announced. &ldquo;I could
+hear three voices though. Two were men and the
+other, a woman.&rdquo;</p>
+<p>&ldquo;Then Mrs. Deline must be here. The keeper lied
+about that part.&rdquo;</p>
+<p>Presently the girls heard footsteps again on the iron
+stairway. They moved to the window, hoping to
+see whomever was descending from the room above.
+However, the little round aperture was so situated
+that it gave a view of only one side of the Point.
+They could not see the stairway nor the stretch of
+beach leading to the hotel.</p>
+<div class="pb" id="Page_145">[145]</div>
+<p>&ldquo;We&rsquo;re certainly learning a lot!&rdquo; Louise said
+crossly. &ldquo;I&rsquo;ve had enough of this. Let&rsquo;s shout for
+help.&rdquo;</p>
+<p>&ldquo;All right,&rdquo; Penny agreed. &ldquo;We may as well find
+out whether or not we&rsquo;re prisoners.&rdquo;</p>
+<p>Crossing to the heavy oak door, she pounded hard
+on the panels. Almost at once the girls heard someone
+coming.</p>
+<p>&ldquo;Don&rsquo;t let on what we suspect,&rdquo; Penny warned her
+companion.</p>
+<p>The next moment the door swung open to admit
+the keeper of the light.</p>
+<div class="pb" id="Page_146">[146]</div>
+<h2 id="c19"><span class="small">CHAPTER</span>

+<br /><i>A LOCKED DOOR</i></h2>
+<p>&ldquo;I was gone a little longer than I meant to be,&rdquo; Jim
+McCoy apologized as he came into the room. &ldquo;Did
+I keep you waiting?&rdquo;</p>
+<p>&ldquo;We probably wouldn&rsquo;t have waited if you hadn&rsquo;t
+locked the door!&rdquo; Louise said sharply.</p>
+<p>The keeper&rsquo;s eyebrows lifted and he looked slightly
+amused. &ldquo;Locked in?&rdquo; he echoed.</p>
+<p>&ldquo;Yes, we couldn&rsquo;t get the door open.&rdquo;</p>
+<p>&ldquo;Oh, it sticks sometimes. Been intending to fix
+it for several days. If you had pushed hard it would
+have opened.&rdquo;</p>
+<p>&ldquo;We certainly pushed hard enough,&rdquo; Penny said
+dryly. She was more than ever certain that the lighthouse
+keeper had unlocked the door only a moment
+before entering. Clearly, he had meant to prevent
+Louise and her from seeing and hearing what went
+on in the room above.</p>
+<div class="pb" id="Page_147">[147]</div>
+<p>&ldquo;Come along,&rdquo; the keeper invited. &ldquo;I&rsquo;ll show you
+the tower.&rdquo;</p>
+<p>&ldquo;No thank you,&rdquo; Penny replied coldly. &ldquo;We&rsquo;ve
+spent so much time here that we&rsquo;ll have to be getting
+back to the hotel.&rdquo;</p>
+<p>&ldquo;As you like.&rdquo; The keeper shrugged, and looked
+relieved by the decision.</p>
+<p>Jim McCoy stepped away from the door, and the
+girls hastened down the iron stairway. No one was
+in sight on the beach. Whoever had visited the lighthouse
+during the time they were imprisoned, had disappeared.</p>
+<p>When they were well down the beach, Louise and
+Penny slackened their pace. Glancing back they saw
+that the keeper of the light still stood on the tiny iron
+balcony watching them.</p>
+<p>&ldquo;That man gives me the creeps,&rdquo; Louise remarked.
+&ldquo;Did you believe what he said about the door sticking?&rdquo;</p>
+<p>&ldquo;I did not,&rdquo; Penny returned with emphasis. &ldquo;I
+think he locked us in on purpose, probably because
+he was expecting visitors and didn&rsquo;t want us to see
+too much.&rdquo;</p>
+<p>&ldquo;As it turned out we didn&rsquo;t learn a thing.&rdquo;</p>
+<p>&ldquo;We have no proof of anything,&rdquo; Penny admitted
+slowly. &ldquo;Nevertheless, we&rsquo;re pretty sure Mrs. Deline
+visited the tower.&rdquo;</p>
+<div class="pb" id="Page_148">[148]</div>
+<p>&ldquo;George Emory too.&rdquo;</p>
+<p>&ldquo;That part is pure guess,&rdquo; Penny said, &ldquo;so we don&rsquo;t
+dare consider it too seriously. Did you ever see Mrs.
+Deline with George Emory?&rdquo;</p>
+<p>&ldquo;Why, no. But then, we&rsquo;ve not been at the hotel
+long.&rdquo;</p>
+<p>&ldquo;Let&rsquo;s find Jerry or Dad,&rdquo; Penny said abruptly.
+&ldquo;We ought to report to them.&rdquo;</p>
+<p>Returning to the hotel, the girls looked in vain for
+Mr. Parker. The publisher was not in his room nor
+anywhere in the lobby. Jerry apparently had not
+returned from Intercept Headquarters.</p>
+<p>&ldquo;There&rsquo;s Mrs. Deline,&rdquo; Louise whispered, jerking
+her head toward a high-backed chair not far from
+the elevator.</p>
+<p>The widow was reading a newspaper. If she saw
+the girls she paid no attention to them.</p>
+<p>&ldquo;Let&rsquo;s talk to her and see what we can learn,&rdquo;
+Louise suggested.</p>
+<p>Penny had another thought. &ldquo;No,&rdquo; she vetoed the
+suggestion. &ldquo;Mrs. Deline would be more likely to
+learn things from us. That woman is clever.&rdquo;</p>
+<p>Just then Mrs. Deline arose, picked up her purse,
+and went out the front door of the hotel. On their
+way to the elevator. Penny and Louise noticed that
+the woman carelessly had left a handkerchief and her
+room key lying on the chair.</p>
+<div class="pb" id="Page_149">[149]</div>
+<p>&ldquo;I&rsquo;ll turn them in at the desk,&rdquo; Louise said, picking
+up the articles.</p>
+<p>&ldquo;Wait, Lou!&rdquo;</p>
+<p>Louise glanced at her chum in surprise.</p>
+<p>&ldquo;I have an idea!&rdquo; Penny revealed, lowering her
+voice. &ldquo;Are you game to try something risky?&rdquo;</p>
+<p>&ldquo;Well, I don&rsquo;t know.&rdquo;</p>
+<p>&ldquo;This chance is tailor-made for us!&rdquo; Penny went
+on. &ldquo;Mrs. Deline simply handed her room key over
+to us. Let&rsquo;s use our opportunity.&rdquo;</p>
+<p>&ldquo;Enter her room?&rdquo; Louise asked, shocked.</p>
+<p>&ldquo;Why not? FBI agents think nothing of examining
+the belongings of a suspected person.&rdquo;</p>
+<p>&ldquo;But we&rsquo;re not FBI agents, Penny. I don&rsquo;t want
+to do it without asking Jerry.&rdquo;</p>
+<p>&ldquo;By that time it will be too late. It&rsquo;s now or
+never.&rdquo;</p>
+<p>&ldquo;Mrs. Deline might catch us in the act.&rdquo;</p>
+<p>&ldquo;That&rsquo;s a chance we&rsquo;ll have to take.&rdquo; Penny, in
+possession of the room key, walked to the front door
+of the hotel. She was reassured to see that Mrs.
+Deline had seated herself on a bench some distance
+from the veranda.</p>
+<p>&ldquo;The coast&rsquo;s clear,&rdquo; Penny reported, coming back
+to Louise. &ldquo;What do you say?&rdquo;</p>
+<p>&ldquo;Well, I suppose so,&rdquo; Louise consented nervously.</p>
+<div class="pb" id="Page_150">[150]</div>
+<p>An elevator shot the girls up to the fourth floor.
+To locate Mrs. Deline&rsquo;s room required but a moment,
+and the halls fortunately were deserted. Penny fitted
+the key into the lock and pushed open the door.</p>
+<p>&ldquo;We&rsquo;ll have to work fast,&rdquo; she said, closing it behind
+them again.</p>
+<p>The room was in perfect order. Only a few toilet
+articles had been set out on the dresser. Mrs. Deline&rsquo;s
+suitcase was only half unpacked.</p>
+<p>&ldquo;It looks to me as if the widow is holding herself
+ready to fly at a moment&rsquo;s notice,&rdquo; Penny commented.
+&ldquo;Otherwise, why didn&rsquo;t she unpack everything?&rdquo;</p>
+<p>&ldquo;What do you expect to find here?&rdquo; Louise asked
+nervously. &ldquo;Let&rsquo;s get it over with fast, Penny.&rdquo;</p>
+<p>&ldquo;Start with the bureau drawers,&rdquo; Penny instructed.
+&ldquo;Search for any papers, letters or the sort. I&rsquo;ll go
+through the suitcase.&rdquo;</p>
+<p>Carefully the girls began examining Mrs. Deline&rsquo;s
+personal belongings. Almost at once Louise reported
+that the bureau contained nothing of interest. Penny,
+however, had more luck. She came upon a pearl-handled
+revolver buried beneath a pile of silk underclothing.</p>
+<p>&ldquo;Jeepers!&rdquo; she whispered, touching the weapon
+gingerly. &ldquo;Now will you believe me when I say
+that the widow isn&rsquo;t the sweet little girl she&rsquo;d have
+us believe!&rdquo;</p>
+<div class="pb" id="Page_151">[151]</div>
+<p>Louise&rsquo;s eyes had opened wide at sight of the revolver.</p>
+<p>&ldquo;And here&rsquo;s that white suit she wore!&rdquo; Penny
+cried, lifting out a folded garment from the suitcase.
+&ldquo;Look, Lou!&rdquo;</p>
+<p>From the skirt of the suit had been cut a neat,
+square hole.</p>
+<p>&ldquo;Well, of all things!&rdquo; Louise exclaimed. &ldquo;What&rsquo;s
+the meaning of that?&rdquo;</p>
+<p>&ldquo;Mrs. Deline wrote something on the skirt&mdash;don&rsquo;t
+you remember? Probably she used a pen with invisible
+ink.&rdquo;</p>
+<p>&ldquo;But why on her skirt, Penny?&rdquo;</p>
+<p>&ldquo;She&rsquo;d just been to the lighthouse. Perhaps she
+learned something there and she wanted to write it
+down before she forgot. Possibly she didn&rsquo;t have
+any paper. Then when she got back here, she either
+destroyed the message, or sent it to someone.&rdquo;</p>
+<p>&ldquo;Well, I don&rsquo;t know,&rdquo; Louise said doubtfully. &ldquo;It&rsquo;s
+all so fantastic. I wouldn&rsquo;t believe a bit of it except
+for this revolver. Having it doesn&rsquo;t look so good.&rdquo;</p>
+<p>&ldquo;And don&rsquo;t forget the green elephant charm,&rdquo;
+Penny reminded her. &ldquo;I wish we could find it here.&rdquo;</p>
+<p>&ldquo;Not a chance. Mrs. Deline always wears it around
+her neck. She had it on today. I noticed.&rdquo;</p>
+<div class="pb" id="Page_152">[152]</div>
+<p>Time fast was elapsing and the girls were worried
+lest someone discover them in the room. Hastily they
+replaced everything as they had found it, and relocking
+the door, stepped out into the hall.</p>
+<p>&ldquo;What&rsquo;s our next move?&rdquo; Louise asked as they
+buzzed for a down-going elevator.</p>
+<p>&ldquo;To tell Jerry and Dad, of course. But before
+that, there&rsquo;s one thing I wish we could do, Lou. It
+would give everything we have to report a more
+substantial basis.&rdquo;</p>
+<p>&ldquo;What&rsquo;s that, Penny?&rdquo;</p>
+<p>&ldquo;Why don&rsquo;t we get our hands on the jade green
+elephant? I&rsquo;ve a hunch that it contains something
+important&mdash;perhaps evidence that would crack the
+case wide open.&rdquo;</p>
+<p>&ldquo;And just how do you propose that we acquire the
+charm?&rdquo; Louise asked sarcastically. &ldquo;Are we to waylay
+Mrs. Deline and take it by force?&rdquo;</p>
+<p>&ldquo;Afraid that wouldn&rsquo;t do.&rdquo;</p>
+<p>&ldquo;There&rsquo;s no other way to get it. Mrs. Deline wears
+that charm as if it were her skin. I&rsquo;ve never seen her
+without it.&rdquo;</p>
+<p>The elevator was coming down so Penny spoke
+hurriedly.</p>
+<p>&ldquo;There is a way,&rdquo; she said softly, &ldquo;if only it will
+work. Think we could get Mrs. Deline to go bathing
+in the surf with us?&rdquo;</p>
+<p>&ldquo;And ruin that lovely hair-do? Don&rsquo;t be silly.&rdquo;</p>
+<div class="pb" id="Page_153">[153]</div>
+<p>&ldquo;All the same, it&rsquo;s worth trying,&rdquo; Penny urged.
+&ldquo;Let&rsquo;s go to our room now and get our bathing suits.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t see any point in it.&rdquo;</p>
+<p>&ldquo;You will,&rdquo; Penny laughed, entering the elevator.
+&ldquo;If my little plan works we&rsquo;ll have keen sport and
+maybe do our country a good turn!&rdquo;</p>
+<div class="pb" id="Page_154">[154]</div>
+<h2 id="c20"><span class="small">CHAPTER</span>
+<br /><span class="large">20</span>
+<br /><i>NYMPHS OF THE SEA</i></h2>
+<p>&ldquo;How you expect to get Mrs. Deline to go swimming
+with us is beyond me!&rdquo; Louise opined as she
+and Penny left the hotel, their bathing suits swinging
+over their arms. &ldquo;It&rsquo;s none too warm today. She
+dislikes us both intensely. Furthermore, she never
+swims.&rdquo;</p>
+<p>&ldquo;Any other reasons?&rdquo; Penny asked cheerfully.</p>
+<p>&ldquo;That should be enough.&rdquo;</p>
+<p>&ldquo;Just wait and watch,&rdquo; Penny chuckled. &ldquo;I just
+hope she doesn&rsquo;t suspect we&rsquo;ve been prowling in her
+room. If she got wise to that she&rsquo;d report us to the
+hotel management.&rdquo;</p>
+<p>Before leaving the hotel the girls had taken care
+to drop the room key in the chair where Mrs. Deline
+had left it. They were confident that no one had
+seen them take the key or enter the room.</p>
+<div class="pb" id="Page_155">[155]</div>
+<p>The widow remained as the girls last had seen her.
+She was sitting on a bench facing the sea, her gaze
+fixed on the deep blue line of the horizon. As the
+girls passed beside her, she looked up, frowning
+slightly.</p>
+<p>&ldquo;We&rsquo;re on our way to the bath house,&rdquo; said Penny,
+her tone implying that the matter was one of great
+importance.</p>
+<p>&ldquo;Really?&rdquo; Mrs. Deline&rsquo;s voice barely was polite.</p>
+<p>&ldquo;Wouldn&rsquo;t you like to come with us?&rdquo; Louise invited
+cordially.</p>
+<p>The invitation took Mrs. Deline by surprise. &ldquo;No,
+thank you,&rdquo; she declined. &ldquo;I can&rsquo;t swim.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll teach you,&rdquo; offered Penny.</p>
+<p>&ldquo;You&rsquo;re too kind. I don&rsquo;t care for the water. I
+particularly detest cold water.&rdquo;</p>
+<p>&ldquo;The air is warming up,&rdquo; Penny tried to encourage
+her. &ldquo;Why not try it with us?&rdquo;</p>
+<p>&ldquo;Nothing could induce me.&rdquo;</p>
+<p>Louise nodded grimly, as much as to say that she
+had known how it would be. Penny would not give
+up. She decided to adopt drastic measures.</p>
+<p>&ldquo;No, I didn&rsquo;t suppose you would go into the
+water,&rdquo; she said. &ldquo;You&rsquo;re probably afraid you&rsquo;ll get
+salt water on that lovely skin of yours, or muss up
+your hair.&rdquo;</p>
+<p>&ldquo;Oh!&rdquo; gasped Mrs. Deline. &ldquo;The very idea!&rdquo;</p>
+<p>&ldquo;Isn&rsquo;t that the reason?&rdquo; Penny pursued ruthlessly.
+&ldquo;You have to protect your beauty?&rdquo;</p>
+<div class="pb" id="Page_156">[156]</div>
+<p>&ldquo;No, it&rsquo;s not the reason!&rdquo; Mrs. Deline snapped.
+&ldquo;If I had a bathing suit, I&rsquo;d show you!&rdquo;</p>
+<p>&ldquo;You can use mine,&rdquo; Penny said promptly. &ldquo;Louise
+has an extra one she&rsquo;ll let me have.&rdquo;</p>
+<p>Mrs. Deline looked trapped and angry. She sprang
+to her feet.</p>
+<p>&ldquo;All right, I&rsquo;ll go swimming!&rdquo; she announced. &ldquo;If
+I catch pneumonia I suppose you&rsquo;ll be satisfied!&rdquo;</p>
+<p>&ldquo;Oh, you&rsquo;ll love the water once you&rsquo;re in,&rdquo; Penny
+said sweetly. &ldquo;The bath house is this way.&rdquo;</p>
+<p>Mrs. Deline spent so long getting into the borrowed
+suit that the girls began to fear she had outwitted
+them. But just as they were ready to give
+up, the woman came out of the dressing room.
+Penny&rsquo;s suit was a size too small for her so that she
+looked as if she had been poured into it. Her legs
+were skinny, her hips bulged. She still wore the elephant
+charm.</p>
+<p>&ldquo;Don&rsquo;t I wish Dad could see her now!&rdquo; Penny muttered.
+&ldquo;What a disillusionment!&rdquo;</p>
+<p>Ignoring the girls, Mrs. Deline walked stiffly toward
+the surf. A wave rolled in, wetting her to the
+knees. Mrs. Deline shrieked and backed away.</p>
+<p>&ldquo;It&rsquo;s freezing!&rdquo; she complained.</p>
+<p>&ldquo;You have to get wet all at once,&rdquo; Penny instructed
+kindly. &ldquo;This way.&rdquo;</p>
+<p>She seized Mrs. Deline&rsquo;s hand and pulled her toward
+the deeper water.</p>
+<div class="pb" id="Page_157">[157]</div>
+<p>&ldquo;Let me go!&rdquo; Mrs. Deline protested, trying to
+shake free. &ldquo;Stop it!&rdquo;</p>
+<p>Penny held fast to her hand. A big roller broke
+over their heads. Mrs. Deline sputtered and choked
+and struggled.</p>
+<p>&ldquo;Oh, this is dreadful!&rdquo; she whimpered.</p>
+<p>&ldquo;You have to watch for the waves and jump just
+as they strike you,&rdquo; Penny laughed. &ldquo;Now!&rdquo;</p>
+<p>She leaped, but the widow mistimed the roller. It
+struck her a resounding whack on her shoulders and
+head.</p>
+<p>&ldquo;Oh! Oh!&rdquo; she moaned.</p>
+<p>&ldquo;Here comes another!&rdquo; warned Louise. &ldquo;A big
+one too!&rdquo;</p>
+<p>Mrs. Deline broke away from Penny. She started
+to run for shore. The big roller overtook her, sweeping
+her from her feet.</p>
+<p>This was the opportunity that Penny awaited.
+Pretending that she too had lost her balance, she allowed
+the tide to carry her straight into Mrs. Deline.
+For an instant they both were beneath the surface of
+the water.</p>
+<p>Penny worked fast. Clutching Mrs. Deline as if
+in terror, she yanked hard at the slender chain that
+held the green elephant charm. It snapped and the
+jade piece came off into her hands. Deftly she thrust
+the charm into the front of her bathing suit. Then
+she popped up above the water, winking at Louise.</p>
+<div class="pb" id="Page_158">[158]</div>
+<p>Mrs. Deline scrambled to her feet, clutching at the
+broken chain.</p>
+<p>&ldquo;See what you&rsquo;ve done!&rdquo; she accused Penny. &ldquo;You
+pulled it apart. My beautiful charm has fallen into
+the water!&rdquo;</p>
+<p>&ldquo;Let me help you look for it,&rdquo; Louise offered, darting
+forward.</p>
+<p>As the pair were groping about on the sandy floor,
+another wave rolled in. Penny neglected to warn
+Mrs. Deline. It struck her from behind, toppling her
+over on her face. Her cap slipped awry and she
+swallowed salt water.</p>
+<p>&ldquo;Oh, I can&rsquo;t stand any more of this!&rdquo; she spluttered.
+&ldquo;It was cruel of you to get me to come into the surf!
+Now I&rsquo;ve lost my charm, and it was all your fault,
+Penny Parker.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll buy you another ornament,&rdquo; the girl offered.
+Seeing Mrs. Deline&rsquo;s distress she felt a bit ashamed of
+herself.</p>
+<p>&ldquo;Another ornament!&rdquo; the widow mocked. &ldquo;I
+don&rsquo;t want another! I want the one I&rsquo;ve lost. It&rsquo;s
+of vital importance to me to keep it.&rdquo;</p>
+<p>Mrs. Deline made another futile search for the
+charm.</p>
+<p>&ldquo;It&rsquo;s been washed away,&rdquo; she cried. &ldquo;I&rsquo;ll never
+find it now!&rdquo;</p>
+<p>Glaring furiously at Penny, she turned and fled to
+the bath house.</p>
+<div class="pb" id="Page_159">[159]</div>
+<p>&ldquo;Did she really lose the charm?&rdquo; Louise demanded
+the moment the girls were alone. &ldquo;Or did you get
+it, Penny?&rdquo;</p>
+<p>Penny answered by producing the green elephant
+charm from the front of her bathing suit where she
+had hidden it.</p>
+<p>&ldquo;Easy as taking candy from a babe,&rdquo; she chuckled.
+&ldquo;My, but was she hopping mad!&rdquo;</p>
+<p>&ldquo;You may not be laughing if your father hears
+about this,&rdquo; Louise warned. &ldquo;He&rsquo;s apt to look at
+matters from a different angle than we do.&rdquo;</p>
+<p>Penny skipped through the shallow water and sat
+down on the beach well beyond the reach of the
+waves. Louise flopped beside her. Eagerly they examined
+the jade green trinket.</p>
+<p>&ldquo;Looks like any ordinary charm to me,&rdquo; Louise
+remarked. &ldquo;No special carving.&rdquo;</p>
+<p>&ldquo;It should open,&rdquo; Penny said. &ldquo;The first night
+when Mrs. Deline and I shared a room, I was sure I
+saw her close it.&rdquo;</p>
+<p>Louise turned the charm over and pried at it with
+a hairpin.</p>
+<p>&ldquo;It does have a back lid!&rdquo; she exclaimed excitedly.
+&ldquo;Penny, I think it&rsquo;s going to open!&rdquo;</p>
+<p>&ldquo;I&rsquo;ll say magic words while you work,&rdquo; Penny
+laughed. &ldquo;Furthermore, I&rsquo;ll keep watch of the bath
+house. We don&rsquo;t want Mrs. Deline to pop out here
+and see us.&rdquo;</p>
+<div class="pb" id="Page_160">[160]</div>
+<p>Louise pried again at the lid of the charm. It gave
+suddenly.</p>
+<p>Inside the tiny cavity was a folded piece of paper.
+While Louise stared in delighted awe, Penny gained
+possession. With nervous haste she unfolded the
+paper. She gazed at it a moment and her face fell.</p>
+<p>&ldquo;Why, I can&rsquo;t make anything of the writing!&rdquo; she
+declared in disappointment. &ldquo;The words don&rsquo;t make
+sense.&rdquo;</p>
+<p>&ldquo;Just a mess of letters,&rdquo; Louise agreed, peering
+over her shoulder.</p>
+<p>The girls were decidedly let-down for they had
+gone to much trouble and risk to obtain the jade ornament.
+But Penny&rsquo;s disappointment did not last long.
+As she stared at the paper, its significance dawned
+upon her.</p>
+<p>&ldquo;Why, this is important, Lou!&rdquo; she cried. &ldquo;Maybe
+we&rsquo;ve stumbled into something big!&rdquo;</p>
+<p>&ldquo;How do you mean?&rdquo;</p>
+<p>&ldquo;Don&rsquo;t you see?&rdquo; Penny demanded triumphantly.
+&ldquo;The letters, of this message must comprise a secret
+code! If only we can break it down we may learn
+all we need to know about Mrs. Deline and her
+strange friends!&rdquo;</p>
+<div class="pb" id="Page_161">[161]</div>

+<br /><i>THE CARDBOARD BOX</i></h2>
+<p>While Penny and Louise were puzzling over the
+strange writing found inside the jade charm, Mrs.
+Deline appeared in the doorway of the bath house.
+Barely in time to escape detection, the girls hid the
+tiny elephant and the paper in the sand.</p>
+<p>Mrs. Deline crossed the beach to speak to the girls.
+Her hair was damp and stringy, her face pinched
+and blue from cold.</p>
+<p>&ldquo;Here&rsquo;s your suit!&rdquo; she snapped, slapping the wet
+garment into the sand at Penny&rsquo;s feet. &ldquo;I hope you
+enjoyed the swim! I&rsquo;m sure I didn&rsquo;t.&rdquo;</p>
+<p>Turning her back, the widow marched to the hotel.</p>
+<p>The moment Mrs. Deline had disappeared into the
+white brick building, Penny dug the jade elephant
+and paper from the sand.</p>
+<p>&ldquo;Let&rsquo;s get dressed,&rdquo; she urged Louise. &ldquo;We&rsquo;ve no
+time to waste.&rdquo;</p>
+<div class="pb" id="Page_162">[162]</div>
+<p>So thrilled were the girls over what they had accomplished
+that they could talk of nothing else.
+Penny felt that by obtaining the jade elephant she
+had proven her case.</p>
+<p>&ldquo;You thought I was only jealous of Mrs. Deline,&rdquo;
+she told Louise triumphantly as they dressed in adjoining
+booths. &ldquo;Now what do you say?&rdquo;</p>
+<p>&ldquo;That you&rsquo;re a genius!&rdquo; Louise praised. &ldquo;Mrs.
+Deline certainly is mixed up in some shady business.&rdquo;</p>
+<p>Once dressed, the girls wrapped the jade elephant
+in a handkerchief and carried it to the hotel. Jerry
+was nowhere to be found, and a bellboy told Penny
+that her father had gone for a walk.</p>
+<p>&ldquo;Perhaps we can work the message out ourselves,&rdquo;
+Penny suggested hopefully. &ldquo;Let&rsquo;s try.&rdquo;</p>
+<p>In their hotel room, the girls spent an hour attempting
+to decipher the strange jargon of letters appearing
+on the paper. At the end of that time. Penny tossed
+aside her pencil in disgust.</p>
+<p>&ldquo;This is a job for an expert,&rdquo; she declared. &ldquo;I certainly
+don&rsquo;t classify as one.&rdquo;</p>
+<p>The telephone jingled. Penny answered it and
+was delighted to hear Jerry&rsquo;s familiar voice. He was
+down in the lobby and had been told that the girls
+wished to see him.</p>
+<p>&ldquo;We certainly do!&rdquo; Penny answered gaily. &ldquo;Hold
+everything! We&rsquo;ll be with you in a jiffy.&rdquo;</p>
+<div class="pb" id="Page_163">[163]</div>
+<p>The elevator being entirely too slow, the girls raced
+down the stairs. Breathlessly they started to tell
+Jerry what they had learned.</p>
+<p>&ldquo;Not here!&rdquo; he said quickly. &ldquo;Let&rsquo;s go outside
+where we won&rsquo;t be overheard.&rdquo;</p>
+<p>Once out in the open with no one close by, Jerry
+lent an attentive ear to Penny&rsquo;s tale of their afternoon
+adventure. He did not have much to say in
+return, but he studied the jade green elephant and
+the paper with deep interest.</p>
+<p>&ldquo;You don&rsquo;t think it&rsquo;s anything?&rdquo; Penny asked in
+disappointment.</p>
+<p>&ldquo;On the contrary, it may be something of very
+great importance,&rdquo; he returned soberly. &ldquo;I&rsquo;ll take
+this to Headquarters. We have an expert on codes
+who should be able to break it in a short while.&rdquo;</p>
+<p>The girls hoped that Jerry would invite them to
+accompany him, but he did not do so. Instead he
+said:</p>
+<p>&ldquo;Penny, you were telling me that Mrs. Deline had
+buried a package in the sand. Any luck in finding it?&rdquo;</p>
+<p>&ldquo;Not a bit.&rdquo;</p>
+<p>&ldquo;You don&rsquo;t think that she went back there and dug
+it up herself?&rdquo;</p>
+<p>&ldquo;We didn&rsquo;t see any footprints.&rdquo;</p>
+<p>&ldquo;How did you mark the place?&rdquo;</p>
+<p>&ldquo;By a stick that someone removed.&rdquo;</p>
+<div class="pb" id="Page_164">[164]</div>
+<p>&ldquo;Not a very reliable way to take observations,&rdquo;
+Jerry remarked. &ldquo;Ever try the clock system?&rdquo;</p>
+<p>The girls looked blank.</p>
+<p>&ldquo;For example,&rdquo; Jerry illustrated, &ldquo;imagine that the
+landscape is like the face of a clock. Now what do
+you see on the hour of two?&rdquo;</p>
+<p>&ldquo;I don&rsquo;t get it,&rdquo; Louise complained.</p>
+<p>&ldquo;Oh, I do!&rdquo; laughed Penny. &ldquo;A big tree!&rdquo;</p>
+<p>&ldquo;That&rsquo;s right,&rdquo; agreed Jerry. &ldquo;And at the hour
+of six?&rdquo;</p>
+<p>&ldquo;Why, a signboard!&rdquo; chuckled Penny. &ldquo;At the
+hour of seven there&rsquo;s a big sand dune!&rdquo;</p>
+<p>&ldquo;If you picture things in your mind as if they&rsquo;re
+on the face of a clock it&rsquo;s much easier to remember
+and keep them in proper proportion. Now, using
+that same system can you recall anything more about
+the place where Mrs. Deline buried the package?&rdquo;</p>
+<p>&ldquo;Not very much,&rdquo; Penny admitted. &ldquo;I didn&rsquo;t take
+notations at the time.&rdquo;</p>
+<p>&ldquo;Speaking of signboards, I remember one,&rdquo; Louise
+said thoughtfully. &ldquo;It was a long distance back from
+the beach, slightly to the right. A cigarette advertisement.&rdquo;</p>
+<p>&ldquo;That&rsquo;s right!&rdquo; agreed Penny.</p>
+<p>&ldquo;Perhaps that will help some,&rdquo; Jerry said. &ldquo;We&rsquo;ll
+have to find the package.&rdquo;</p>
+<p>&ldquo;Then you believe Mrs. Deline is an Enemy
+Agent?&rdquo; Penny asked eagerly.</p>
+<div class="pb" id="Page_165">[165]</div>
+<p>&ldquo;I&rsquo;ve thought so for quite a while now,&rdquo; Jerry admitted.
+&ldquo;I didn&rsquo;t say it for fear of building up your
+hopes. Anyhow, we&rsquo;ve got to work quietly in this
+business.&rdquo;</p>
+<p>&ldquo;Poor Dad,&rdquo; Penny murmured, &ldquo;I&rsquo;m afraid it will
+break him up to learn the truth. Do you say I should
+tell him right away, Jerry?&rdquo;</p>
+<p>&ldquo;Why not?&rdquo; Jerry demanded, his eyes amused.
+&ldquo;Your father may have a few things to break to you
+too, Penny.&rdquo;</p>
+<p>&ldquo;Meaning what?&rdquo;</p>
+<p>&ldquo;I&rsquo;ll let your father do his own talking,&rdquo; Jerry said,
+getting up from the hotel bench. &ldquo;Have to go now.&rdquo;</p>
+<p>&ldquo;Wait!&rdquo; Penny pleaded. &ldquo;You&rsquo;ve not told us anything.
+Do you think Mrs. Deline has been aiding that
+flier who escaped from a Canadian prison camp?&rdquo;</p>
+<p>Jerry deliberately let the question pass. &ldquo;Listen!&rdquo;
+he said urgently. &ldquo;I may not see you girls again until
+after dinner. Want to help me tonight?&rdquo;</p>
+<p>&ldquo;Doing what?&rdquo; Penny asked.</p>
+<p>&ldquo;I want you to lead me to the place where Mrs.
+Deline buried that package.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll do our best.&rdquo;</p>
+<p>&ldquo;Then if I don&rsquo;t see you earlier, meet me here at
+nine o&rsquo;clock. It should be dark by that time.&rdquo;</p>
+<p>&ldquo;We&rsquo;ll be here,&rdquo; Penny promised, her eyes glowing.</p>
+<div class="pb" id="Page_166">[166]</div>
+<p>At dinner that night the girls told Mr. Parker of
+their appointment to meet Jerry. Penny would have
+explained about the package, but before she could
+do so, Mrs. Deline joined the group. Mr. Parker
+immediately invited her to dine with them. To the
+annoyance of Penny and Louise she accepted with
+alacrity.</p>
+<p>The girls fully expected that Mrs. Deline would
+make some reference to the incident of the afternoon.
+Instead she avoided the subject, talking of her experiences
+in China and the Orient. Despite their
+prejudice, Penny and Louise were compelled in all
+honesty to acknowledge to themselves that the widow
+was a brilliant, entertaining conversationalist.</p>
+<p>Over the coffee cups Mrs. Deline spoke casually of
+a play which was showing at the local theatre. Before
+Penny could say a word, Mr. Parker had suggested
+that he buy tickets for the night&rsquo;s performance.</p>
+<p>&ldquo;I&rsquo;d love to go,&rdquo; Mrs. Deline accepted instantly.</p>
+<p>&ldquo;Good!&rdquo; Mr. Parker, approved. &ldquo;I&rsquo;ll get four
+tickets.&rdquo;</p>
+<p>&ldquo;Two,&rdquo; Penny corrected grimly. &ldquo;Louise and I
+already have an appointment.&rdquo;</p>
+<p>&ldquo;That&rsquo;s so,&rdquo; Mr. Parker recalled belatedly.</p>
+<p>Mrs. Deline looked so pleased that Penny was
+sorely tempted to abandon the meeting with Jerry.
+Only the realization that the task ahead was vitally
+important, kept her silent.</p>
+<div class="pb" id="Page_167">[167]</div>
+<p>At eight o&rsquo;clock Mr. Parker and Mrs. Deline left
+the hotel for the theatre. With an hour to kill, Penny
+and Louise were very restless. They read the evening
+paper and watched the clock.</p>
+<p>&ldquo;Here&rsquo;s an interesting news item,&rdquo; Penny remarked,
+indicating a brief story on an inner page of the paper.
+&ldquo;It says an enemy submarine was sighted not many
+miles from here&mdash;just off the coast.&rdquo;</p>
+<p>&ldquo;Did they get it?&rdquo; Louise inquired absently.</p>
+<p>&ldquo;I guess not. The story doesn&rsquo;t say, except that
+the air patrol dropped bombs.&rdquo;</p>
+<p>&ldquo;Wonder what a single sub was doing so close
+here?&rdquo; Louise speculated. &ldquo;Oh, well, we&rsquo;ve nothing
+to fear.&rdquo;</p>
+<p>A clock chimed the hour of nine. On the first
+stroke, the girls arose and hastened to keep their appointment
+with Jerry. The night was closing in
+dark. Along the shore no lights were showing for
+the dim-out was rigidly enforced at Sunset Beach.</p>
+<p>&ldquo;Where&rsquo;s Jerry?&rdquo; Penny asked as they reached the
+bench where they had promised to meet him. &ldquo;Hope
+he didn&rsquo;t forget.&rdquo;</p>
+<p>Ten minutes elapsed. Penny was examining the
+luminous dial of her wrist watch when someone came
+striding down the gravel path.</p>
+<p>&ldquo;Hello,&rdquo; Jerry greeted the girls. &ldquo;Sorry to have
+kept you waiting. All set for adventure?&rdquo;</p>
+<p>&ldquo;Lead on!&rdquo; Penny laughed.</p>
+<div class="pb" id="Page_168">[168]</div>
+<p>Taking each of them by an elbow, Jerry guided
+the girls down the deserted beach. Twice they passed
+guards who merely stared and allowed them to pass
+unchallenged.</p>
+<p>&ldquo;Any news about that code?&rdquo; Penny questioned as
+they walked along.</p>
+<p>&ldquo;It&rsquo;s a tough one to break,&rdquo; Jerry replied briefly.
+&ldquo;Experts have been trying to take it apart ever since
+I left you girls this afternoon.&rdquo;</p>
+<p>&ldquo;Then it really is something?&rdquo; Penny asked,
+scarcely daring to hope.</p>
+<p>&ldquo;It certainly is,&rdquo; Jerry replied heartily. &ldquo;We&rsquo;re
+pretty sure now that Mrs. Deline is mixed up in a
+bad business. But we can&rsquo;t act until we know absolutely.&rdquo;</p>
+<p>&ldquo;This will be a horrible shock to Dad,&rdquo; Penny remarked.
+&ldquo;He&rsquo;s at the theatre with Mrs. Deline now.&rdquo;</p>
+<p>&ldquo;At least she&rsquo;s out of the way, so there&rsquo;s no chance
+she&rsquo;ll see us at work,&rdquo; Jerry commented. &ldquo;Think
+you can find the place to dig?&rdquo;</p>
+<p>Penny had marked it well in her mind, but at night
+everything looked different. After some uncertainty,
+the girls agreed upon the dune where the package had
+been buried.</p>
+<p>&ldquo;With the tide low we&rsquo;ll have plenty of time,&rdquo;
+Jerry said. &ldquo;Well, let&rsquo;s go! Was the package buried
+deep?&rdquo;</p>
+<p>&ldquo;Not more than a foot,&rdquo; Penny supplied.</p>
+<div class="pb" id="Page_169">[169]</div>
+<p>&ldquo;Then if it&rsquo;s here, we&rsquo;ll find it. Let&rsquo;s block this
+area off and cover it systematically.&rdquo;</p>
+<p>For an hour the trio toiled. Twice one of the
+beach guards passed by and Penny was surprised that
+he paid no heed to what they were doing.</p>
+<p>&ldquo;Orders!&rdquo; Jerry chuckled. &ldquo;You didn&rsquo;t think we
+could come out here and prowl around without questions
+being asked? The guard was tipped off. He&rsquo;ll
+help us by whistling if anyone comes this way.&rdquo;</p>
+<p>Louise, who had been industriously digging, gave
+a low cry.</p>
+<p>&ldquo;Find something?&rdquo; Jerry demanded.</p>
+<p>&ldquo;I&rsquo;m not sure. I think so.&rdquo;</p>
+<p>The next instant Louise lifted a small package from
+its sand tomb. Before Jerry could warn her, she had
+torn apart the pasteboard cover.</p>
+<p>&ldquo;Why, it contains pencils!&rdquo; she exclaimed in disgust.
+&ldquo;Pencils!&rdquo;</p>
+<p>Jerry leaped to her side. One glance and he took
+the box from her.</p>
+<p>&ldquo;Those objects may look like pencils,&rdquo; he drawled.
+&ldquo;But take it from me, they&rsquo;re a bit more deadly.&rdquo;</p>
+<p>Penny had moved close. She and Louise stared in
+awe at the collection.</p>
+<p>&ldquo;Bombs,&rdquo; Jerry explained briefly. &ldquo;One of these
+little pencils contains enough explosive to blow us
+all to Kingdom Come!&rdquo;</p>
+<div class="pb" id="Page_170">[170]</div>
+<h2 id="c22"><span class="small">CHAPTER</span>
+<br /><span class="large">22</span>
+<br /><i>UNFINISHED BUSINESS</i></h2>
+<p>The cardboard box contained in addition to
+the pencil bombs a shiny knife and several grooved,
+pear-shaped objects.</p>
+<p>&ldquo;What are those?&rdquo; Louise asked curiously. &ldquo;They
+look like hand grenades.&rdquo;</p>
+<p>&ldquo;That&rsquo;s what they are,&rdquo; said Jerry, lifting one from
+the box. &ldquo;It&rsquo;s a mighty useful weapon for close fighting.
+A strong man can throw a grenade twenty-five
+to thirty-five yards and it does damage over a large
+area.&rdquo;</p>
+<p>Penny gingerly inspected one of the grenades.</p>
+<p>&ldquo;It won&rsquo;t bite you,&rdquo; Jerry laughed. &ldquo;Nor will it
+explode in your hand. When you&rsquo;re ready to throw
+a grenade you hold it with the lever under your fingers.
+Just before you toss it, pull the pin.&rdquo;</p>
+<p>&ldquo;Isn&rsquo;t it apt to explode while you&rsquo;re holding it?&rdquo;
+Penny asked dubiously.</p>
+<div class="pb" id="Page_171">[171]</div>
+<p>&ldquo;Not while the lever is held. When the grenade
+leaves the hand, the lever flies off. Then the fuse
+ignites and in about seven seconds you have your
+explosion.&rdquo;</p>
+<p>&ldquo;Nice little gadgets,&rdquo; Penny said. She replaced the
+grenade in its box and ran a finger over the sharp edge
+of the steel-bladed knife.</p>
+<p>&ldquo;Mrs. Deline evidently planted these weapons here
+for someone else to use,&rdquo; Jerry remarked. &ldquo;We&rsquo;ll put
+them back just as they were.&rdquo;</p>
+<p>&ldquo;Put them back!&rdquo; Penny echoed. &ldquo;Why, Jerry,
+wouldn&rsquo;t that be playing right into their hands?
+Shouldn&rsquo;t we destroy these things?&rdquo;</p>
+<p>&ldquo;No, it&rsquo;s much wiser to have the place watched.&rdquo;</p>
+<p>Light dawned upon Penny. &ldquo;Oh, I see!&rdquo; she exclaimed.
+&ldquo;In that way you hope to learn Mrs.
+Deline&rsquo;s accomplices!&rdquo;</p>
+<p>&ldquo;Exactly.&rdquo;</p>
+<p>Jerry replaced everything in the box which he
+carefully buried in the sand. Then he obliterated all
+freshly made footmarks.</p>
+<p>&ldquo;It may be necessary to watch this place for days,&rdquo;
+he said thoughtfully.</p>
+<p>&ldquo;And what of Mrs. Deline?&rdquo; Penny asked. &ldquo;Will
+she be allowed complete freedom?&rdquo;</p>
+<p>&ldquo;That&rsquo;s for my superiors to decide. It seems to me,
+though, that more is to be gained by allowing her to
+remain at liberty than by arresting her.&rdquo;</p>
+<p>&ldquo;I&rsquo;m all for jail myself,&rdquo; said Penny.</p>
+<div class="pb" id="Page_172">[172]</div>
+<p>&ldquo;Just be patient,&rdquo; Jerry smiled. &ldquo;And whatever
+you do, don&rsquo;t drop a hint to Mrs. Deline of what we
+suspect.&rdquo;</p>
+<p>&ldquo;She knows I dislike her.&rdquo;</p>
+<p>&ldquo;That&rsquo;s all right, but don&rsquo;t let her guess that you
+consider her guilty of anything more serious than
+making a play for your father.&rdquo;</p>
+<p>&ldquo;What about Dad? Shouldn&rsquo;t I warn him?&rdquo;</p>
+<p>&ldquo;Let me take care of that part,&rdquo; Jerry smiled.</p>
+<p>&ldquo;All right,&rdquo; Penny agreed reluctantly. &ldquo;Just be
+sure that you don&rsquo;t muff it. Remember, you&rsquo;re playing
+with my future!&rdquo;</p>
+<p>Jerry finished smoothing out the footprints in the
+sand and then escorted the girls to the hotel.</p>
+<p>&ldquo;I must report to Headquarters without delay,&rdquo;
+he said, pausing at the hotel entrance. &ldquo;Don&rsquo;t worry
+about the package. We&rsquo;ll have the place watched
+every minute.&rdquo;</p>
+<p>After Jerry had gone, Penny and Louise entered
+the hotel.</p>
+<p>&ldquo;Is my father here yet?&rdquo; Penny asked the desk
+clerk.</p>
+<p>&ldquo;No, Miss. And there&rsquo;s a message for him. As
+soon as he comes in he&rsquo;s to call Major Gregg.&rdquo;</p>
+<p>Penny repeated the name thoughtfully. &ldquo;That&rsquo;s
+a new one on me,&rdquo; she remarked. &ldquo;Dad seems to have
+friends I know nothing about.&rdquo;</p>
+<div class="pb" id="Page_173">[173]</div>
+<p>&ldquo;Oh, the Major comes to the hotel frequently,&rdquo;
+the clerk returned, smiling. &ldquo;He and your father are
+well acquainted.&rdquo;</p>
+<p>As the girls crossed the lobby to a drinking fountain,
+Louise said teasingly:</p>
+<p>&ldquo;I&rsquo;m afraid you&rsquo;ve lost track of your father lately,
+Penny. You&rsquo;ve been so upset about Mrs. Deline that
+you&rsquo;ve scarcely noticed anything or anyone else.&rdquo;</p>
+<p>&ldquo;Dad&rsquo;s been holding out on me, that&rsquo;s evident.
+Wonder what he&rsquo;s to call Major Gregg about?&rdquo;</p>
+<p>&ldquo;Why not wait up and see?&rdquo;</p>
+<p>&ldquo;Not a bad idea,&rdquo; Penny approved instantly. &ldquo;He
+and Mrs. Deline should be getting in anytime
+now.&rdquo;</p>
+<p>&ldquo;I&rsquo;m not waiting up,&rdquo; announced Louise with a
+sleepy yawn. &ldquo;In fact, I&rsquo;m on my way to bed this
+minute.&rdquo;</p>
+<p>To prove her words she started for the elevator.
+Penny debated whether or not to follow and finally
+decided to remain in the lobby.</p>
+<p>An hour elapsed. Penny was half asleep by the
+time Mrs. Deline and Mr. Parker entered the hotel
+together. They were chatting animatedly and would
+not have seen her had she not scrambled from the
+wing chair.</p>
+<p>Seeing Penny, Mrs. Deline quickly bade Mr.
+Parker good night and vanished into an elevator.</p>
+<div class="pb" id="Page_174">[174]</div>
+<p>&ldquo;You shouldn&rsquo;t have waited up,&rdquo; Mr. Parker chided
+his daughter. &ldquo;Why, it&rsquo;s nearly midnight.&rdquo;</p>
+<p>&ldquo;There&rsquo;s an important message for you, Dad.
+You&rsquo;re to call Major Gregg.&rdquo;</p>
+<p>Mr. Parker looked disconcerted. &ldquo;How long ago
+did that call come, Penny?&rdquo;</p>
+<p>&ldquo;About an hour ago. Or that&rsquo;s when I learned of
+it.&rdquo;</p>
+<p>Mr. Parker went quickly to a telephone booth and
+was gone for some time. When he returned his face
+was animated.</p>
+<p>&ldquo;Good news?&rdquo; Penny asked eagerly.</p>
+<p>&ldquo;Not exactly,&rdquo; Mr. Parker replied, sliding into a
+chair beside her and dropping his voice. &ldquo;A message
+from Interceptor Headquarters. Monitoring machines
+have traced the outlaw radio station again.
+The broadcast finished about an hour ago.&rdquo;</p>
+<p>&ldquo;And where was the station located this time,
+Dad?&rdquo;</p>
+<p>&ldquo;Seemingly at or near the lighthouse.&rdquo;</p>
+<p>&ldquo;The lighthouse!&rdquo; Penny exclaimed. She was so
+startled that her voice rose to a high pitch, attracting
+the attention of a passing bellboy.</p>
+<p>&ldquo;Not so loud, Penny,&rdquo; her father warned. &ldquo;The
+strange thing was that the broadcast seemed to come
+from a cave, the same as before, although the monitoring
+machines charted it as being close to the lighthouse.&rdquo;</p>
+<div class="pb" id="Page_175">[175]</div>
+<p>&ldquo;The only one I know about near the Point is
+Crystal Cave,&rdquo; Penny said thoughtfully. &ldquo;Dad,
+maybe the broadcast did come from the lighthouse!&rdquo;</p>
+<p>&ldquo;That&rsquo;s government property. Penny, and the man
+in charge is beyond suspicion. Furthermore, the
+deep, echo effect couldn&rsquo;t come from anywhere except
+a cave.&rdquo;</p>
+<p>&ldquo;Unless it were a sound effect, Dad.&rdquo;</p>
+<p>&ldquo;What&rsquo;s that?&rdquo; Mr. Parker asked, startled. &ldquo;I
+don&rsquo;t get you, Penny.&rdquo;</p>
+<p>&ldquo;I mean, maybe the cave set-up is just a sound
+effect and nothing more. Only the other night I
+heard one in a radio play and it sounded as if the
+actors really were in a cave. Isn&rsquo;t it done by an echo
+chamber or something of the sort?&rdquo;</p>
+<p>&ldquo;That would be possible,&rdquo; Mr. Parker agreed. &ldquo;At
+Interceptor Headquarters it was assumed that a mistake
+had been made in charting the location of the station.&rdquo;</p>
+<p>&ldquo;Then the lighthouse hasn&rsquo;t been investigated?&rdquo;</p>
+<p>&ldquo;Not to my knowledge.&rdquo;</p>
+<p>&ldquo;Well, it should be!&rdquo; Penny exclaimed. &ldquo;Louise
+and I were there today and we saw&mdash;&rdquo;</p>
+<p>&ldquo;Yes?&rdquo; Mr. Parker questioned as she suddenly
+broke off.</p>
+<p>&ldquo;We saw a lot that didn&rsquo;t look right,&rdquo; Penny finished,
+deciding not to bring Mrs. Deline&rsquo;s name into
+the discussion. &ldquo;Mr. McCoy had visitors and while
+they were there he kept us locked up.&rdquo;</p>
+<div class="pb" id="Page_176">[176]</div>
+<p>&ldquo;My word! Why didn&rsquo;t you report to the police?&rdquo;</p>
+<p>&ldquo;Well, we weren&rsquo;t entirely sure,&rdquo; Penny said
+lamely. &ldquo;The door just closed and locked, and Mr.
+McCoy let on that it had a trick latch. Then he released
+us, but not until after the visitors had gone.&rdquo;</p>
+<p>&ldquo;Did you see the persons?&rdquo;</p>
+<p>&ldquo;No, we only heard their voices. We weren&rsquo;t able
+to overhear any of the conversation.&rdquo;</p>
+<p>Without explaining what he intended to do, Mr.
+Parker again closed himself into a telephone booth.
+Not until he returned did he tell Penny that he had
+called Interceptor Headquarters and that Army men
+had been sent to the lighthouse to make a thorough
+check-up.</p>
+<p>&ldquo;Now it&rsquo;s late,&rdquo; he said briskly, &ldquo;and you&rsquo;re overdue
+for bed, Penny. Better fly up.&rdquo;</p>
+<p>&ldquo;Aren&rsquo;t you coming?&rdquo;</p>
+<p>&ldquo;Not just now. I have a little unfinished business.&rdquo;</p>
+<p>Penny hesitated, unwilling to go to bed when she
+sensed adventure in the offing. As she groped in her
+mind for an excuse to remain, the doors at the front
+entrance to the hotel began to spin. Jerry came hurrying
+into the lobby. Seeing Penny and her father
+he made a straight line for them.</p>
+<p>&ldquo;The code&rsquo;s been broken!&rdquo; he announced, addressing
+Penny.</p>
+<p>&ldquo;What did they learn, Jerry?&rdquo; she asked eagerly.</p>
+<div class="pb" id="Page_177">[177]</div>
+<p>&ldquo;It&rsquo;s just as you thought, Penny.&rdquo; Jerry dropped
+his bombshell. &ldquo;Mrs. Deline definitely is an Enemy
+Agent. Apparently she was sent to Sunset Beach to
+aid that escaped prisoner I told you about!&rdquo;</p>
+<div class="pb" id="Page_178">[178]</div>

+<br /><i>NIGHT ADVENTURE</i></h2>
+<p>As Jerry made the startling announcement, Penny
+glanced anxiously at her father. In the excitement
+of the moment she had not thought how much of a
+shock it might be to him to learn that Mrs. Deline was
+an agent employed by a foreign country. To her
+astonishment, he looked neither surprised nor dismayed.</p>
+<p>&ldquo;So you have the proof, Jerry!&rdquo; Mr. Parker exclaimed.
+&ldquo;That&rsquo;s fine! But what&rsquo;s all this about a
+code? How did you stumble onto it?&rdquo;</p>
+<p>&ldquo;No time for details now,&rdquo; Jerry answered tersely.
+&ldquo;Penny turned the trick&mdash;she and Louise saw Mrs.
+Deline bury a package in the sand.&rdquo;</p>
+<p>&ldquo;And Mrs. Deline brought that package from the
+lighthouse,&rdquo; Penny interposed eagerly. &ldquo;Mr. McCoy
+must have given it to her.&rdquo;</p>
+<div class="pb" id="Page_179">[179]</div>
+<p>&ldquo;What&rsquo;s the plan of action?&rdquo; Mr. Parker demanded.
+&ldquo;Army men already have gone to the lighthouse to
+search that place thoroughly.&rdquo;</p>
+<p>&ldquo;Our job is to keep watch of the dune where the
+package was buried. Naturally we have no way of
+knowing what time anyone will show up there. It
+may be an all night wait.&rdquo;</p>
+<p>&ldquo;I&rsquo;ll be with you in a minute,&rdquo; Mr. Parker declared.
+&ldquo;Just as soon as I get an overcoat.&rdquo;</p>
+<p>He started toward the elevator, then came back to
+the group.</p>
+<p>&ldquo;What about Mrs. Deline?&rdquo; he asked. &ldquo;She&rsquo;s here
+in the hotel. Went to her room only a few minutes
+ago.&rdquo;</p>
+<p>&ldquo;She&rsquo;ll be placed under arrest,&rdquo; Jerry said. &ldquo;Better
+call her on the telephone and get her down here.
+Don&rsquo;t let her suspect that you think anything is
+wrong.&rdquo;</p>
+<p>Mr. Parker vanished into the nearest telephone
+booth.</p>
+<p>&ldquo;I can&rsquo;t understand it,&rdquo; Penny murmured to Jerry.
+&ldquo;I was sure Dad was head over heels in love with Mrs.
+Deline. Why, it didn&rsquo;t even seem to ruffle him when
+he learned the truth about her.&rdquo;</p>
+<p>Jerry grinned. &ldquo;Maybe,&rdquo; he drawled, &ldquo;that was
+because he knew all the time.&rdquo;</p>
+<div class="pb" id="Page_180">[180]</div>
+<p>Penny was dumbfounded. &ldquo;You mean&mdash;&rdquo; she
+stammered, &ldquo;You mean that Dad&rsquo;s been acting a part?
+Pretending to admire Mrs. Deline while actually he
+didn&rsquo;t?&rdquo;</p>
+<p>&ldquo;Something like that. You see, your Dad became
+interested in the outlaw radio station and the men
+who operate it. By making inquiries before he left
+Riverview, he obtained information that made him
+think Mrs. Deline might be involved in some way.
+He knew she never had been in China but spent many
+years in Japan. He learned also that instead of being
+a newspaper correspondent, she had carried on secret
+work for various governments.&rdquo;</p>
+<p>&ldquo;Dad knew all that! And he never let on to me!&rdquo;</p>
+<p>&ldquo;He couldn&rsquo;t very well, Penny. If you had guessed
+the truth, you&rsquo;d have given it away by your manner&mdash;no
+matter how much you tried to act natural.&rdquo;</p>
+<p>&ldquo;What a little nit-wit I&rsquo;ve been!&rdquo;</p>
+<p>&ldquo;You have not,&rdquo; Jerry denied warmly. &ldquo;Anyone
+else would have acted the same. Without knowing
+it, you helped your father a lot. You turned up evidence
+he never could have obtained alone.&rdquo;</p>
+<p>&ldquo;Where do you fit into the picture, Jerry? Did
+Dad send for you?&rdquo;</p>
+<p>&ldquo;You don&rsquo;t send for anyone in the Army,&rdquo; Jerry
+explained, grinning. &ldquo;By pure luck I was assigned
+here on a special mission. Your father learned I was
+coming, so we united forces.&rdquo;</p>
+<div class="pb" id="Page_181">[181]</div>
+<p>&ldquo;Then you&rsquo;ve both known from the first about
+Mrs. Deline?&rdquo;</p>
+<p>&ldquo;We&rsquo;ve had a dark brown suspicion, Penny. But
+no proof until tonight.&rdquo;</p>
+<p>Penny drew a deep breath. Before she could ask
+another question, her father came hurrying down the
+hotel corridor.</p>
+<p>&ldquo;Mrs. Deline&rsquo;s not in her room!&rdquo; he reported. &ldquo;She
+doesn&rsquo;t answer.&rdquo;</p>
+<p>&ldquo;She went upstairs only a few minutes ago,&rdquo; Penny
+recalled.</p>
+<p>&ldquo;Yes, she did, but she&rsquo;s not there now.&rdquo;</p>
+<p>&ldquo;Maybe she&rsquo;s asleep,&rdquo; Jerry said, &ldquo;and failed to hear
+the &rsquo;phone. We&rsquo;ll have to check.&rdquo;</p>
+<p>Without explaining why the matter was urgent,
+Mr. Parker arranged with the desk clerk to have one
+of the hotel maids go to Mrs. Deline&rsquo;s room. While
+the trio waited in the upstairs corridor, the woman
+rapped several times on the bedroom door, and failing
+to get a response, unlocked it with her master key.</p>
+<p>&ldquo;Mrs. Deline!&rdquo; she called, softly at first, then in
+a louder voice.</p>
+<p>There was no answer.</p>
+<p>The maid then snapped on the light. &ldquo;Why,
+there&rsquo;s no one here!&rdquo; she cried. &ldquo;The bed&rsquo;s not been
+slept in!&rdquo;</p>
+<p>&ldquo;That&rsquo;s what I was afraid of,&rdquo; muttered Mr. Parker.</p>
+<div class="pb" id="Page_182">[182]</div>
+<p>With Jerry and Penny, he entered the bedroom.
+Everything was in perfect order. However, Mrs.
+Deline&rsquo;s suitcase was gone and all her belongings had
+been removed from the closet.</p>
+<p>&ldquo;She&rsquo;s skipped without paying her room rent!&rdquo; the
+maid exclaimed. &ldquo;I&rsquo;ll call the manager!&rdquo;</p>
+<p>Penny was peering into the waste paper basket beside
+the desk.</p>
+<p>&ldquo;Look!&rdquo; she drew the attention of her father and
+Jerry. &ldquo;Burned letters and papers!&rdquo;</p>
+<p>Digging into the basket, she brought up several
+charred sheets of paper. They were unreadable and
+crumpled in her hand.</p>
+<p>&ldquo;This was a bad break for us&mdash;Mrs. Deline getting
+away!&rdquo; Jerry exclaimed in disgust. &ldquo;Evidently her
+work at Sunset Beach is finished. She&rsquo;s moving on to
+another pasture.&rdquo;</p>
+<p>&ldquo;But she can&rsquo;t be far away,&rdquo; Penny reasoned.
+&ldquo;After all, we know when she came to her room.&rdquo;</p>
+<p>&ldquo;There still may be a chance to nab her,&rdquo; Mr.
+Parker said. &ldquo;We&rsquo;ll notify the police to guard all the
+roads and the airport. I&rsquo;ll report to Major Gregg
+too.&rdquo;</p>
+<p>Without awaiting the arrival of the hotel manager,
+the trio hastened to the lobby. There Jerry and Mr.
+Parker made several telephone calls.</p>
+<div class="pb" id="Page_183">[183]</div>
+<p>&ldquo;Now let&rsquo;s be on our way up the beach,&rdquo; Jerry
+urged anxiously. &ldquo;We&rsquo;ve killed too much time as
+it is.&rdquo;</p>
+<p>Penny half expected that her father would refuse
+permission for her to go along. To her delight he
+merely said:</p>
+<p>&ldquo;I suppose there&rsquo;s no keeping you here, Penny.
+Well, come with us. I guess you&rsquo;ve earned the right
+by your good work.&rdquo;</p>
+<p>It was a dark night, warm but misty. No lights
+were showing outside the hotel, though far up the
+beach the powerful lighthouse beacon cut swathes
+across the black sea.</p>
+<p>&ldquo;What&rsquo;s the plan?&rdquo; Mr. Parker asked Jerry.</p>
+<p>&ldquo;The entire coast for fifty miles is being watched.
+I thought just on a chance we might keep vigil at the
+place where Mrs. Deline buried the package of explosives.
+Someone may show up there. On the other
+hand, Penny tipped off the fact that she knew where
+the bundle was buried.&rdquo;</p>
+<p>&ldquo;Mrs. Deline watched Louise and me through a spy
+glass,&rdquo; Penny recalled ruefully. &ldquo;She knew we didn&rsquo;t
+find the package though.&rdquo;</p>
+<p>&ldquo;That&rsquo;s our assignment anyhow,&rdquo; Jerry said. &ldquo;To
+keep watch of that particular place until relieved by
+Army men.&rdquo;</p>
+<div class="pb" id="Page_184">[184]</div>
+<p>The Parker car was on the hotel lot close by. Getting
+it, the trio took the beach road but stopped some
+distance from the lighthouse. Not wishing the car
+to attract the attention of any passer-by, it was left
+parked on a private driveway. Jerry, Penny and
+her father then crossed the dunes afoot and proceeded
+up the beach until they came to their station.</p>
+<p>&ldquo;Think this is the place?&rdquo; Penny asked skeptically.</p>
+<p>&ldquo;I know it is,&rdquo; Jerry replied. &ldquo;Remember what
+I told you about taking observations? Let&rsquo;s see if the
+package is still here?&rdquo;</p>
+<p>He began digging in one of the dunes. Almost at
+once he came upon the box of explosives.</p>
+<p>&ldquo;Exactly as we left it,&rdquo; he reported, replacing the
+sand. &ldquo;No one&rsquo;s been here.&rdquo;</p>
+<p>&ldquo;I doubt anyone will come,&rdquo; Mr. Parker commented.
+&ldquo;Probably afraid.&rdquo;</p>
+<p>High overhead and out of sight, Penny heard the
+drone of planes on coastal patrol. She stared up into
+the dark sky and then toward the sea. The tide was
+coming in and long rolling waves washed the beach,
+dashed themselves on the shoreline and retreated.</p>
+<p>&ldquo;We&rsquo;ll have to get down out of sight,&rdquo; Jerry
+warned. &ldquo;Mustn&rsquo;t be seen from the road or the ocean
+either one.&rdquo;</p>
+<p>&ldquo;How about this spot?&rdquo; Mr. Parker suggested,
+pointing to a hollow between two giant dunes.</p>
+<p>The place seemed exactly right, so the trio flattened
+themselves on the sand. Jerry looked at the
+luminous dial of his watch.</p>
+<div class="pb" id="Page_185">[185]</div>
+<p>&ldquo;One fifteen,&rdquo; he announced. &ldquo;No sign of activity.&rdquo;</p>
+<p>&ldquo;And no sign of any soldiers,&rdquo; Mr. Parker added.
+&ldquo;I hope that whoever is to take over here shows up
+before long.&rdquo;</p>
+<p>&ldquo;I don&rsquo;t,&rdquo; Penny said, snuggling close between her
+father and Jerry. &ldquo;I&rsquo;m having fun!&rdquo;</p>
+<p>&ldquo;If anything should develop, it&rsquo;s apt to be serious
+business,&rdquo; Jerry warned. &ldquo;I&rsquo;m inclined to think that
+we tipped our hand and nothing will happen.&rdquo;</p>
+<p>An hour elapsed. During that time there was no
+sound save the roar of the restless sea. The warm
+sand made a comfortable couch, and despite her best
+intentions, Penny caught herself dozing. She had all
+she could do to keep awake.</p>
+<p>&ldquo;What time is it now?&rdquo; she presently asked.</p>
+<p>&ldquo;Two thirty-five,&rdquo; Jerry answered. &ldquo;It doesn&rsquo;t
+look as if there&rsquo;s to be any activity, but then the
+night&rsquo;s young.&rdquo;</p>
+<p>&ldquo;The night may be, but I&rsquo;m not,&rdquo; Mr. Parker
+grumbled, shifting into a more comfortable position.
+&ldquo;Wonder when our relief is to show up?&rdquo;</p>
+<p>&ldquo;Must be some mix up on orders. We&rsquo;re probably
+stuck here for the night.&rdquo;</p>
+<p>&ldquo;In that case, Penny should return to the hotel.&rdquo;</p>
+<p>&ldquo;Oh, no. Dad! Anyway, if I left now I might
+attract the attention of anyone watching this place.&rdquo;</p>
+<div class="pb" id="Page_186">[186]</div>
+<p>&ldquo;You thought that one up!&rdquo; her father chuckled.
+&ldquo;Except for ourselves, there&rsquo;s no person within a
+quarter of a mile of this place.&rdquo;</p>
+<p>&ldquo;You&rsquo;re wrong about that,&rdquo; murmured Jerry, stiffening
+to alert attention.</p>
+<p>&ldquo;What&rsquo;s up, Jerry?&rdquo; Mr. Parker said quickly.
+&ldquo;You act as if you were seeing things!&rdquo;</p>
+<p>&ldquo;I am, Chief! Look to the right&mdash;between us and
+the lighthouse!&rdquo;</p>
+<p>Mr. Parker and Penny gazed intently in the direction
+indicated.</p>
+<p>&ldquo;Can&rsquo;t see a thing,&rdquo; Mr. Parker whispered. &ldquo;Your
+eyes must be tricking you, Jerry.&rdquo;</p>
+<p>&ldquo;Wait just a minute.&rdquo;</p>
+<p>Even as Jerry spoke, a shadowy figure emerged
+from the mists. The man came swiftly down the
+beach, making no sound as he walked. When he was
+very close, the revolving beacon of the lighthouse
+singled him out for a fleeting instant. Brief as was
+the moment of illumination, Penny recognized the
+man.</p>
+<p>&ldquo;George Emory!&rdquo; she whispered tensely. &ldquo;What&rsquo;s
+he doing here?&rdquo;</p>
+<div class="pb" id="Page_187">[187]</div>
+<h2 id="c24"><span class="small">CHAPTER</span>
+<br /><span class="large">24</span>
+<br /><i>OUT OF THE SEA</i></h2>
+<p>The answer to Penny&rsquo;s whispered question soon
+became obvious. George Emory looked carefully
+about the windswept beach. The three tense watchers
+thought that he might approach the dune where
+they lay hidden, but he did not.</p>
+<p>Instead, the man paused while several yards away
+and gazed toward the sea. A moment he stood thus,
+silhouetted against the sky. Then using a glowing
+flashlight, he began making wide sweeps with his arm.</p>
+<p>&ldquo;A signal!&rdquo; Jerry whispered. &ldquo;He&rsquo;s trying to attract
+the attention of a boat out at sea!&rdquo;</p>
+<p>&ldquo;Shall we go for him?&rdquo; asked Mr. Parker.</p>
+<p>&ldquo;Wait!&rdquo; Jerry advised. &ldquo;He&rsquo;s not the only one
+we&rsquo;re after. We&rsquo;re stalking bigger game.&rdquo;</p>
+<p>At intervals for the next fifteen minutes, George
+Emory repeated the flashlight signals. Then he
+turned off the light and waited.</p>
+<div class="pb" id="Page_188">[188]</div>
+<p>Anxiously, Jerry, Penny and Mr. Parker kept their
+faces turned to the sea. They sensed that the hour of
+action was at hand, and it worried them that Army
+men had failed to arrive.</p>
+<p>&ldquo;Look, Dad!&rdquo; Penny suddenly whispered. She
+had glimpsed far from shore a long shadowy object
+which easily could be a boat. No lights were showing
+nor had she heard any sound.</p>
+<p>&ldquo;I don&rsquo;t see a thing,&rdquo; Mr. Parker whispered back.
+&ldquo;Yes! Now I do! Jove! It looks like a submarine
+that&rsquo;s surfaced. I can make out the conning tower!&rdquo;</p>
+<p>&ldquo;But why would it dare come here?&rdquo; Penny
+speculated. &ldquo;Won&rsquo;t it be detected by the patrol
+planes?&rdquo;</p>
+<p>&ldquo;Tonight&rsquo;s a bad night,&rdquo; Jerry pointed out. &ldquo;Besides,
+the shore is so indented at this point of coast
+that perfect protection is almost impossible. They&rsquo;re
+sending a boat, that&rsquo;s sure!&rdquo;</p>
+<p>A small craft had been launched from the wave-washed
+deck of the submarine. Manned by two men
+who rowed with muffled oars, it slowly approached
+the shore. When it was very close the watchers behind
+the sand dune saw by its grotesque sausage shape
+that it was a large, rubber boat. Like a gray ghost
+it slid over the water.</p>
+<p>Mr. Parker gripped Penny&rsquo;s hand in an encouraging
+squeeze.</p>
+<div class="pb" id="Page_189">[189]</div>
+<p>&ldquo;Wish you were safe at the hotel,&rdquo; he whispered.
+&ldquo;I was a fool to let you come.&rdquo;</p>
+<p>Penny&rsquo;s heart pounded but she shook her head
+vigorously. Not for anything would she have missed
+the adventure. However, she was cool headed
+enough to realize that the situation was not shaping
+up well for her father and Jerry.</p>
+<p>There were two men visible in the rubber boat,
+unquestionably armed. Then George Emory must
+be reckoned with and the arrival of others might be
+expected at any moment. Jerry carried a revolver
+but her father had no weapon. Already it was too
+late for any member of the trio to safely go for
+help.</p>
+<p>&ldquo;That sub may intend to land Secret Agents here,&rdquo;
+Jerry speculated. &ldquo;But from the code message we
+deciphered, it&rsquo;s more likely they plan to take aboard
+one or more passengers.&rdquo;</p>
+<p>&ldquo;Perhaps that escaped flier,&rdquo; Penny supplied.</p>
+<p>&ldquo;He&rsquo;s a valuable man to them. Well worth the
+risk they&rsquo;re taking to try to rescue him.&rdquo;</p>
+<p>&ldquo;If passengers are to go aboard, where are they?&rdquo;
+Penny whispered. &ldquo;There&rsquo;s no one here but George
+Emory.&rdquo;</p>
+<p>&ldquo;We must wait and watch. We&rsquo;ll soon see enough
+or I miss my guess.&rdquo;</p>
+<div class="pb" id="Page_190">[190]</div>
+<p>The rubber boat had reached the surf and was being
+churned by the waves. Two men in full military
+uniform, leaped out and guided the boat to the beach.
+George Emory waded out to meet them. Shaking
+the hand of each, he spoke rapidly in German.
+Though Mr. Parker understood the language, he was
+unable to catch a word.</p>
+<p>Tensely, the trio waited and watched. At any
+moment they feared that the men from the submarine
+might seek the cache of explosives hidden not
+far away. Soberly Jerry and Mr. Parker considered
+trying to reach the box in the sand. To do so they
+must cross an open, unprotected span of beach with
+every likelihood of being seen.</p>
+<p>&ldquo;Let&rsquo;s wait and see what happens,&rdquo; Mr. Parker advised.
+&ldquo;We shouldn&rsquo;t risk calling attention to ourselves.&rdquo;</p>
+<p>George Emory and his two companions obviously
+were awaiting someone. Nervously they paced the
+beach. Several times Mr. Emory looked at his watch.
+Then from far down the road came the sound of a
+car traveling at high speed. Tires screamed in protest
+as the auto came to a sudden halt on the paved
+road back from the beach.</p>
+<p>&ldquo;That&rsquo;s why they&rsquo;ve waited!&rdquo; Jerry whispered.</p>
+<p>Barely a minute elapsed before two figures were
+seen coming swiftly from the direction of the road.
+A man and a woman crawled through the bushes,
+under the fence, and walked hurriedly across deep
+sand to the beach.</p>
+<div class="pb" id="Page_191">[191]</div>
+<p>&ldquo;Mrs. Deline!&rdquo; Penny identified the woman. &ldquo;The
+man with her is the same fellow who stole food from
+our camp!&rdquo;</p>
+<p>&ldquo;I&rsquo;d know his face from photographs I&rsquo;ve seen,&rdquo;
+contributed Jerry. &ldquo;He&rsquo;s Oscar Kleinbrock, escaped
+German prisoner. The man I was sent here to trace!&rdquo;</p>
+<p>Mrs. Deline and her companion reached the group
+of men who awaited them.</p>
+<p>&ldquo;You are five minutes late,&rdquo; George Emory reproved.</p>
+<p>&ldquo;Can we help it?&rdquo; Mrs. Deline snapped. &ldquo;We&rsquo;re
+lucky to be here at all. Do you know that the road
+is being watched?&rdquo;</p>
+<p>&ldquo;By whom?&rdquo;</p>
+<p>&ldquo;Army men. We were nearly stopped but were
+able to turn off into the thicket and wait.&rdquo;</p>
+<p>&ldquo;Then there&rsquo;s no time to waste in talk,&rdquo; George
+Emory said curtly. Turning, he spoke to the German
+flier in his own language.</p>
+<p>&ldquo;He&rsquo;s telling him to get aboard the rubber boat,&rdquo;
+Mr. Parker interpreted tensely. &ldquo;Now they&rsquo;re saying
+goodbye to Emory and Mrs. Deline.&rdquo;</p>
+<p>&ldquo;Somehow we must hold them all here!&rdquo; Jerry
+whispered grimly.</p>
+<p>&ldquo;It&rsquo;s two against five. And they&rsquo;re armed.&rdquo;</p>
+<div class="pb" id="Page_192">[192]</div>
+<p>Mr. Parker and Jerry looked at each other, fully
+realizing how slim was their chance of success. They
+were not thinking of themselves but of Penny and
+what could happen to her if they failed. Mr. Parker
+touched her arm.</p>
+<p>&ldquo;Penny,&rdquo; he whispered. &ldquo;Slip away in the darkness
+and make a dash for the hotel. Jerry and I will
+try to hold them until help comes. Just keep low as
+you run or those fiends may take a pot-shot at you.&rdquo;
+Penny would not desert her father and Jerry.
+Stubbornly, she shook her head.</p>
+<p>&ldquo;We want to know that you are safe,&rdquo; Jerry urged.
+&ldquo;Please go while you still have a chance. You can
+help us most by bringing help.&rdquo;</p>
+<p>Penny&rsquo;s determination to remain, weakened. Yet
+reason told her she never could reach the hotel and
+return with help in time to do any good. It dawned
+upon her that Jerry was only saying what he did to
+get her safely away.</p>
+<p>&ldquo;If only we had the box of explosives!&rdquo; she whispered.
+&ldquo;With it we might have a chance against
+those men!&rdquo;</p>
+<p>&ldquo;It&rsquo;s too late to dig up the box now,&rdquo; said Jerry.
+&ldquo;We probably couldn&rsquo;t find it without a light. And
+the noise we&rsquo;d make&mdash;&rdquo;</p>
+<p>&ldquo;Let me try,&rdquo; Penny interrupted.</p>
+<div class="pb" id="Page_193">[193]</div>
+<p>&ldquo;All right, see if you can get your hands on the
+box,&rdquo; her father agreed suddenly. &ldquo;Slip back of the
+dune, and then circle. Don&rsquo;t try to cross the beach.
+Be careful! Remember the least sound will bring a
+hail of bullets.&rdquo;</p>
+<p>Penny nodded and slipped away into the darkness,
+crawling on hands and knees. Barely had she left
+the shelter of the big sand dune than she heard two
+shots fired in quick succession.</p>
+<p>&ldquo;Those came from Jerry&rsquo;s revolver!&rdquo; she thought.
+&ldquo;Oh, it was a trick to get me safely away! Now he
+and Dad are in for fireworks!&rdquo;</p>
+<p>Raising her head above the protecting sand dune,
+Penny saw why Jerry had fired. The rubber boat
+was being launched. To delay the attack would
+mean that the entire party might escape.</p>
+<p>&ldquo;They&rsquo;ll all get away!&rdquo; Penny thought in dismay.
+&ldquo;How can Jerry and Dad hold them single handed?&rdquo;</p>
+<p>George Emory returned Jerry&rsquo;s fire with deadly
+aim. The bullets bit into the dune, throwing up little
+geysers of sand.</p>
+<p>&ldquo;Launch the boat!&rdquo; he shouted savagely to the men
+from the submarine. &ldquo;Get away while you can! Be
+quick!&rdquo;</p>
+<p>Jerry and Mr. Parker were determined that the
+party should not escape. As the men sought to launch
+the rubber boat, they made a concerted rush for the
+German flier who was to be taken aboard the waiting
+submarine. Caught by surprise, he went down beneath
+their blows.</p>
+<div class="pb" id="Page_194">[194]</div>
+<p>Fearful of hitting his own man, George Emory
+dared not fire again. Instead, he and the crewmen of
+the submarine fell upon Jerry and Mr. Parker. In
+the melee, one person could not be distinguished from
+another.</p>
+<p>&ldquo;Fools! Fools!&rdquo; cried Mrs. Deline as she watched
+the fierce, uneven struggle. &ldquo;There is no time to be
+lost!&rdquo;</p>
+<p>Jerry and Mr. Parker were putting up the fight of
+their lives, but they were no match for four able
+bodied, trained men. Penny, desperate with anxiety,
+saw that the struggle could end only in one way&mdash;disaster
+for Jerry and her father.</p>
+<p>&ldquo;If I had that box of explosives maybe I could help
+them!&rdquo; flashed through her mind.</p>
+<p>Rolling over a dune, she ran to the place near the
+fence where she thought the cache was buried. Frantically
+she clawed and dug at the sand. She could
+not find the box.</p>
+<p>&ldquo;It must be here!&rdquo; she told herself desperately.
+&ldquo;Or was it hidden in the next dune?&rdquo;</p>
+<p>She tried another place slightly to the right. As
+she dug, she heard a sound behind her. Turning
+swiftly, she saw Mrs. Deline starting across the beach
+toward her.</p>
+<div class="pb" id="Page_195">[195]</div>
+<p>&ldquo;Oh, no, you don&rsquo;t!&rdquo; the woman shouted.</p>
+<p>Penny&rsquo;s hand encountered something hard and
+firm. The box of explosives! Digging wildly, she
+lifted it from the bed of sand and sprang to her feet.
+Her fingers closed upon one of the hand grenades.</p>
+<p>&ldquo;Get back!&rdquo; she ordered Mrs. Deline, balancing
+herself as if to throw.</p>
+<p>The woman stopped short, then retreated a few
+steps. But only for a moment was she frightened.</p>
+<p>&ldquo;Why, you infant, you couldn&rsquo;t throw a grenade!&rdquo;
+she jeered. &ldquo;You don&rsquo;t know how. Besides, you
+haven&rsquo;t the nerve!&rdquo;</p>
+<p>&ldquo;Get back!&rdquo; Penny ordered again. &ldquo;I warn you.&rdquo;</p>
+<p>Mrs. Deline laughed scornfully and came on.</p>
+<p>Even the thought of throwing a hand grenade terrified
+Penny. She knew that she could not deliberately
+harm Mrs. Deline or even the men who were mercilessly
+beating her father and Jerry. Yet she had to
+do something.</p>
+<p>&ldquo;Maybe I can destroy the rubber boat!&rdquo; she
+thought. &ldquo;It&rsquo;s far enough away so that no one should
+be hurt by the explosion.&rdquo;</p>
+<p>Whirling away from Mrs. Deline, Penny faced the
+sea. Fixing her eyes on her target, the rubber boat
+at the water&rsquo;s edge, she hurled the grenade.</p>
+<p>&ldquo;Idiot!&rdquo; cried Mrs. Deline, flinging herself flat on
+the sand to protect her face from flying fragments.</p>
+<div class="pb" id="Page_196">[196]</div>
+<p>Penny did likewise. The grenade dropped with
+a thud on the sand beside the rubber boat. Her aim
+had been perfect. But there was no explosion. Belatedly,
+Penny realized that she had forgotten to pull
+the safety pin.</p>
+<p>Mrs. Deline kept her face buried beneath her arms
+and did not yet know what had happened. Sick with
+the knowledge that she had failed, Penny was desperate.
+Her father and Jerry were being cruelly
+beaten by their opponents. In another minute they
+would be overpowered and the Germans would escape
+to the waiting submarine.</p>
+<p>&ldquo;I can&rsquo;t let them get away!&rdquo; Penny whispered. &ldquo;I
+must do something!&rdquo;</p>
+<p>Remembering the pencil bombs, she groped in the
+cardboard box for them. They were not there. Instead,
+her fingers closed upon the sharp bladed knife.</p>
+<p>&ldquo;I&rsquo;ll slash the rubber boat!&rdquo; she thought. &ldquo;I&rsquo;ll try
+to make a hole in it!&rdquo;</p>
+<p>Before Mrs. Deline realized what the girl was about,
+Penny darted down the beach. The men from the
+submarine did not see her. Reaching the rubber boat,
+she leaped into it. Working with desperate haste,
+she jabbed the knife through the bottom. The material
+was tough and it took all of her strength to
+make a long jagged gash. Water seeped in, slowly at
+first, then faster.</p>
+<div class="pb" id="Page_197">[197]</div>
+<p>&ldquo;I&rsquo;ve done it!&rdquo; Penny thought jubilantly. &ldquo;I&rsquo;ve
+done it!&rdquo;</p>
+<p>Her triumph was fleeting. The next instant the
+girl was struck a hard stunning blow from behind.
+As she collapsed in a limp little heap on the sand, she
+dimly saw the cruel, angry face of Mrs. Deline. Then
+all went black and she knew no more.</p>

+<br /><i>A SCOOP FOR UNCLE SAM</i></h2>
+<p>Penny opened her eyes and wondered where
+she was. For a moment she could remember nothing
+of what had transpired. Gradually, she realized that
+she was lying down, her head pillowed in someone&rsquo;s
+lap. She seemed to be in a fast-moving motor boat
+for she could hear the wash of waves against the craft.
+In panic she decided that she must be a prisoner enroute
+to the German submarine. She struggled to
+sit up.</p>
+<p>&ldquo;Easy there, partner,&rdquo; said a soothing voice.</p>
+<p>Penny twisted sideways to look at the speaker.
+&ldquo;Jerry!&rdquo; she whispered.</p>
+<p>&ldquo;You&rsquo;re all right,&rdquo; he said, pressing her gently
+back. &ldquo;We&rsquo;ll get you to a doctor in a few minutes.&rdquo;</p>
+<p>&ldquo;A doctor, my eye!&rdquo; Penny protested with spirit.</p>
+<p>&ldquo;That was a nasty blow Mrs. Deline gave you on
+the head,&rdquo; contributed another voice.</p>
+<div class="pb" id="Page_199">[199]</div>
+<p>Penny turned again and saw her father. His shirt
+was half torn off and there was a long gash on his
+cheek.</p>
+<p>&ldquo;Dad, you&rsquo;re hurt!&rdquo;</p>
+<p>&ldquo;Nothing but a few scratches, Penny. Jerry took
+worse punishment than I did. But you should see
+the other fellows!&rdquo;</p>
+<p>&ldquo;What happened?&rdquo; Penny asked. &ldquo;Where am I
+anyhow?&rdquo;</p>
+<p>&ldquo;In a patrol boat bound for the hotel.&rdquo;</p>
+<p>&ldquo;But what happened on the beach? The last I remember
+was when I tried to slash the rubber boat.&rdquo;</p>
+<p>&ldquo;You not only tried, you did!&rdquo; chuckled Jerry.
+&ldquo;Mrs. Deline struck you on the head with something&mdash;maybe
+a rock&mdash;and you went down for the count.
+About that time, some of the Army boys arrived.
+Mrs. Deline and her crowd tried to make a get-away,
+but the boat couldn&rsquo;t be launched.&rdquo;</p>
+<p>&ldquo;Then what happened?&rdquo; Penny demanded as Jerry
+paused for breath.</p>
+<p>&ldquo;The two members of the sub crew tried to swim.
+They were picked up by a patrol boat that had been
+drawn to the locality by the gun fire.&rdquo;</p>
+<p>&ldquo;And Mrs. Deline?&rdquo;</p>
+<p>&ldquo;She and her pal Emory, together with the escaped
+flier, struck off across the sand dunes.&rdquo;</p>
+<p>&ldquo;They didn&rsquo;t get away?&rdquo;</p>
+<div class="pb" id="Page_200">[200]</div>
+<p>&ldquo;Not on your life. They reached the road and
+there found a nice reception awaiting them! Right
+now the three are lodged at Headquarters.&rdquo;</p>
+<p>Penny took a deep breath. Her head was throbbing
+but she scarcely felt the pain.</p>
+<p>&ldquo;What about Jim McCoy at the lighthouse?&rdquo; she
+inquired.</p>
+<p>&ldquo;He was taken into custody earlier in the evening.
+A portable broadcasting outfit was found on the
+premises.&rdquo;</p>
+<p>&ldquo;Then Mr. McCoy really was the man responsible
+for those mysterious broadcasts&mdash;the Voice from the
+Cave?&rdquo;</p>
+<p>&ldquo;No doubt he had helpers,&rdquo; Mr. Parker contributed.
+&ldquo;We expect to track down most of the ring
+now that the leaders have been captured. At any
+rate, we&rsquo;ve put an end to the broadcasts. Your other
+theory was right too, Penny.&rdquo;</p>
+<p>&ldquo;What theory, Dad?&rdquo;</p>
+<p>&ldquo;That the cave effect was produced by an echo
+chamber.&rdquo;</p>
+<p>&ldquo;Then no broadcast ever originated in a cave?&rdquo;</p>
+<p>&ldquo;Probably not. We know McCoy shifted locations
+frequently. Tonight was the first time he ever
+dared broadcast from the lighthouse.&rdquo;</p>
+<p>&ldquo;And what of the old beachcomber, Jake Skagway?&rdquo;</p>
+<div class="pb" id="Page_201">[201]</div>
+<p>&ldquo;Just a beachcomber,&rdquo; Jerry answered. &ldquo;He had
+no connection with Emory or Mrs. Deline.&rdquo;</p>
+<p>Penny lay perfectly still for a few minutes, gazing
+up at the dark sky. A few stars pricked the black
+canopy above her, and now and then a quarter moon
+peeped from behind a cloud screen.</p>
+<p>&ldquo;How did I get aboard this boat?&rdquo; she presently
+inquired.</p>
+<p>&ldquo;Another patrol boat came by,&rdquo; Jerry explained.
+&ldquo;In fact, after all the fireworks, just about everyone
+in Sunset Beach arrived on the scene. We wanted to
+get you to a doctor so we took the first transportation
+that offered.&rdquo;</p>
+<p>&ldquo;Almost there now too,&rdquo; added Mr. Parker.</p>
+<p>Penny sat up. The shore was dark but she could
+dimly see the dark Crystal Inn hotel.</p>
+<p>&ldquo;I don&rsquo;t need a doctor,&rdquo; she laughed. &ldquo;I&rsquo;m feeling
+better every minute. My, won&rsquo;t Louise be green
+with envy when she learns what she missed!&rdquo;</p>
+<p>&ldquo;I&rsquo;d say she was lucky,&rdquo; Mr. Parker corrected.
+&ldquo;Penny, you don&rsquo;t seem to realize what a narrow
+escape we all had.&rdquo;</p>
+<p>&ldquo;That&rsquo;s right,&rdquo; added Jerry, &ldquo;those men were desperate,
+and they&rsquo;d have stopped at nothing. I guess
+we owe our lives to you, Penny.&rdquo;</p>
+<p>Penny loved the praise. Nevertheless, she replied
+with a show of modesty:</p>
+<div class="pb" id="Page_202">[202]</div>
+<p>&ldquo;Oh, I didn&rsquo;t do a thing, Jerry. As a matter of
+record, I nearly messed up the show. When I threw
+that hand grenade I forgot to pull the safety pin.&rdquo;</p>
+<p>&ldquo;I&rsquo;m glad you did,&rdquo; chuckled Jerry. &ldquo;If it had
+exploded, we might not be here now.&rdquo;</p>
+<p>Penny sat very still, thinking over what had happened.
+Events were a bit hazy in her mind and many
+questions remained unanswered.</p>
+<p>&ldquo;The submarine?&rdquo; she asked after a moment.</p>
+<p>&ldquo;Sunk,&rdquo; Jerry replied. &ldquo;One of our patrol planes
+scored a direct hit.&rdquo;</p>
+<p>&ldquo;I guess that brings me up to date,&rdquo; Penny sighed,
+&ldquo;There&rsquo;s only one thing that bothers me.&rdquo;</p>
+<p>&ldquo;What&rsquo;s that?&rdquo; inquired her father.</p>
+<p>&ldquo;Did you know who Mrs. Deline was when you invited
+her to come with us to Sunset Beach?&rdquo;</p>
+<p>&ldquo;No, but I had a healthy suspicion that she might
+be working against our country, Penny. I first met
+Mrs. Deline at the Club. However, she was rather
+transparent in making a play for my attention. In
+checking up I discovered that she never had been in
+China and never had written a newspaper story in
+her life. When she practically invited herself to ride
+with us to Sunset Beach, I thought I&rsquo;d try to find out
+more about her little game.&rdquo;</p>
+<p>&ldquo;I acted so silly about everything,&rdquo; Penny acknowledged,
+deeply ashamed. &ldquo;I&rsquo;m sorry, Dad.&rdquo;</p>
+<div class="pb" id="Page_203">[203]</div>
+<p>&ldquo;You needn&rsquo;t be, Penny. At times you were rude
+to Mrs. Deline which was wrong. But your actions
+served a good purpose by keeping the woman so
+diverted that she never was on her guard.&rdquo;</p>
+<p>Shore was very close. As the powerful engines of
+the motor boat became muted, Penny said wistfully:</p>
+<p>&ldquo;Now that your work is done here, Jerry, I suppose
+you&rsquo;ll be winging off to some far corner of the
+country.&rdquo;</p>
+<p>&ldquo;Not for a few days at least,&rdquo; he reassured her.
+&ldquo;I&rsquo;m expecting a furlough and I&rsquo;ll spend it right here
+at Sunset Beach. We&rsquo;ll cram those days full of fun,
+Penny. We&rsquo;ll swim and golf and dance. We&rsquo;ll make
+every minute count.&rdquo;</p>
+<p>The boat grated gently against the dock and a
+sailor leaped out to make the craft fast. Mr. Parker
+and Jerry helped Penny ashore. Though she tried
+to stand steady upon her feet, the boards rocked beneath
+her.</p>
+<p>&ldquo;Hook on,&rdquo; invited Jerry, offering an arm.</p>
+<p>Mr. Parker supported her on the other side, and
+thus they walked slowly toward the hotel.</p>
+<p>&ldquo;The Three Musketeers!&rdquo; chuckled the editor.
+&ldquo;&lsquo;One for all, and all for one.&rsquo;&rdquo;</p>
+<p>&ldquo;We do make a trio,&rdquo; agreed Penny. &ldquo;Tonight
+it seems just as it did when we were together in Riverview
+working on a big news story. There&rsquo;s one
+difference though.&rdquo;</p>
+<p>&ldquo;What&rsquo;s that?&rdquo; asked Jerry.</p>
+<div class="pb" id="Page_204">[204]</div>
+<p>&ldquo;Tonight we were actors in a little drama that
+should be page one on any newspaper. Yet neither
+of you news hawks so much as spoke of trying to get
+a scoop for the <i>Riverview Star</i>.&rdquo;</p>
+<p>&ldquo;Good reason,&rdquo; rumbled Mr. Parker. &ldquo;The story
+of what happened tonight may never be published.&rdquo;</p>
+<p>&ldquo;I understand, Dad. If the news were printed
+now it might give valuable information to the enemy.&rdquo;</p>
+<p>Penny paused to catch her breath. With Jerry
+and her father still supporting her, she turned to face
+the restless sea. The patrol boat had slipped away
+into the darkness. Far up shore, unmindful that her
+faithless master had gone, the bright beacon from the
+lighthouse swept the water at regular intervals.
+Nothing seemed changed.</p>
+<p>&ldquo;Curtain going down on one of the best adventures
+of my life,&rdquo; Penny said softly. &ldquo;Who cares that the
+<i>Riverview Star</i> missed the story? Why, this was an
+A-1 scoop for Uncle Sam!&rdquo;</p>

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations

+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United

+ _AN UNINVITED GUEST_
+
+
+"Mrs. Weems, what can be delaying Dad? He promised faithfully to be home
+by three o'clock and it's nearly five now. Unless we start soon we'll
+never get to Sunset Beach tonight."
+
+Penny Parker, in blue slacks and a slightly mussed polo shirt, gazed
+disconsolately at the over-loaded automobile standing on the gravel
+driveway of the Parker home. Aided by Mrs. Weems, the family housekeeper,
+she had spent hours packing the sedan with luggage and camping equipment.
+Though the task long had been finished, Mr. Parker failed to arrive.
+
+"Your father is a very busy man," Mrs. Weems responded to the girl's
+question. "No doubt he's been held up at the office."
+
+"Then why doesn't he telephone? It's driving me crazy to wait and
+wonder."
+
+Penny's freckled little face twisted into a grimace of worry. For weeks
+she and her father, editor-owner of the _Riverview Star_, had planned a
+vacation camping trip to the nearby seashore resort, Sunset Beach. Twice
+the excursion had been postponed. Penny, who knew well her father's habit
+of changing his mind, was fearful that even now something would cause
+another vexing delay.
+
+"I'm going to call the _Star_ office this minute!" she declared, starting
+for the house.
+
+Mrs. Weems busied herself gathering up loose odds and ends that had blown
+about the yard. She was cramming waste paper into a box when Penny banged
+out the door, her eyes tragic.
+
+"I couldn't reach Dad!" she announced. "He left the office more than an
+hour ago."
+
+"Then he should have been home before this," Mrs. Weems agreed.
+
+"Something's happened. Maybe he's been run down by a car--"
+
+"Now Penny, stop such wild talk," the housekeeper interrupted sternly.
+"You know better."
+
+"But Dad was struck by an automobile last winter. What else could delay
+him?"
+
+"A dozen things," Mrs. Weems replied. "Probably a business engagement."
+
+"In that case, wouldn't he have telephoned me?"
+
+"Perhaps not. Now do stop fretting, Penny. Your father will be here
+before long."
+
+"He'd better be," Penny said darkly.
+
+Sitting down on the stone step by the door, she scuffed the toe of her
+tennis shoe back and forth in the gravel. Mrs. Weems who had cared for
+the girl ever since the death of Mrs. Parker, gazed at her sternly.
+
+"Now do stop grieving!" she chided. "That's no way to act just because
+you're impatient and disappointed."
+
+"But I've been disappointed three times now," Penny complained. "We
+planned on starting early and having a picnic lunch on the road. Dad
+promised faithfully--"
+
+A car drove up to the curb at the front of the house. Penny sprang
+hopefully to her feet. However, it was not her father who had arrived.
+Instead, her chum, Louise Sidell, alighted and came running across the
+yard.
+
+"Oh, I'm glad I'm not too late to say goodbye to you, Penny!" she cried.
+"How soon are you starting?"
+
+"I'd like to know the answer to that one myself. Dad hasn't put in an
+appearance. He was due here at three o'clock."
+
+"Why, I saw him about twenty minutes ago," Louise replied, turning to
+inspect the over-loaded sedan. "My, how did you accumulate so much
+luggage?"
+
+Penny ignored the question to ask one of her own. "Where did you see Dad,
+Lou?"
+
+"Why, riding in a car." Louise's dark eyes sparkled mischievously as she
+added: "With a beautiful brunette too."
+
+"You're joking."
+
+"I am not. Your father was riding with Mrs. Deline. She's a widow, you
+know, and has lived in Riverview less than a month."
+
+Mrs. Weems, who had overheard the conversation, came over to the steps.
+
+"Mrs. Deline, did you say?" she inquired, slightly disturbed. "I've heard
+of her."
+
+"And so have I!" declared Penny with biting emphasis. "Why, that woman
+would make the Merry Widow look like a dead number! She'd better not try
+to sink her hooks into Dad!"
+
+"Penelope!" the housekeeper reproved sternly.
+
+"Well, you know what everyone says--"
+
+"Please don't repeat idle gossip," Mrs. Weems requested. "I'm sure Mrs.
+Deline is a very fine woman."
+
+"She's the slickest serpent that ever free-wheeled into Riverview!" Penny
+said heatedly. "I saw her in action last week-end at the Country Club.
+Why, she simply went out of her way to cultivate any man who had an
+income of more than twenty-five thousand a year."
+
+"Penny, your father is a sensible man," the housekeeper reproved.
+"Unfortunately, it's a quality I'm afraid you didn't inherit."
+
+Louise, unhappy to have stirred up such a hornet's nest, said hastily:
+"Maybe it wasn't Mrs. Deline I saw. The car went by so fast."
+
+"Oh, I'm not worried. Dad can handle a bigger package of dynamite than
+Mrs. Deline. It just makes me irritated because he doesn't get here."
+
+Tossing her head, Penny crossed to the loaded automobile where she
+switched on the radio. She tuned it carelessly. After a moment a blurred
+voice blared forth:
+
+"Attention Comrades!"
+
+Penny turned quickly to glance at the dial, for she realized that she did
+not have the local station WZAM.
+
+"Attention Comrades!" the announcer commanded again. "This is the Voice
+from the Cave."
+
+There followed a strange jibberish of words which were in no language
+that Penny ever before had heard.
+
+"Mrs. Weems! Louise!" she called excitedly. "I think I've tuned in an
+outlaw short wave station! Just listen!"
+
+Louise and the housekeeper hastened over to the car. Penny tried
+desperately to tune the station in more clearly. Instead she lost it
+completely.
+
+"Did you hear what that announcer said?" she asked eagerly. "Most of it I
+couldn't understand. I'm sure it was in code!"
+
+"Code!" Mrs. Weems exclaimed in amazement.
+
+"I'm sure I didn't have one of the regular stations! It must have been a
+short wave broadcast beamed at a particular group of persons. The
+announcer began: 'Attention Comrades!'"
+
+"Can't you tune in again?" Louise demanded.
+
+Penny twisted the dial without success. She was still trying when a taxi
+cab drew up at the front door.
+
+"There's your father now!" Louise declared.
+
+"And see who's with him!" Penny added, craning her neck. "It _is_ Mrs.
+Deline."
+
+Mrs. Weems, decidedly flustered, hurriedly removed her apron. In an
+undertone she warned Penny to be polite to the unexpected visitor.
+
+Mr. Parker, a tall, lean man with hair only touched by gray, stepped from
+the taxi. The woman he assisted was attractively slender, and dressed in
+an expensive tailored suit. Her face was cold and serene, but so striking
+that it commanded instant interest. Penny's spirits sagged as she
+observed that the widow came equipped with luggage.
+
+"Now what?" she muttered.
+
+Mr. Parker escorted Mrs. Deline across the yard, introducing her first to
+Mrs. Weems and then to the girls.
+
+"Mrs. Deline is riding with us to Sunset Beach," he explained to Penny.
+"She intended to go by train but failed to get a reservation."
+
+"Coaches are so unbearable," Mrs. Deline said in an affected drawl. "It
+was so nice of Mr. Parker to invite me to share your car."
+
+"I'm afraid it may not be so pleasant for you," Penny replied. She tried
+to speak cordially but the words came in stiff little jerks. "There's not
+much room."
+
+"Nonsense!" said Mr. Parker. "Mrs. Deline will ride up front. Penny,
+you'll have to battle it out with the luggage."
+
+By the time Mrs. Deline's suitcase and hat boxes were stowed away, there
+was indeed little room left in the rear seat for a passenger. Penny's
+face was very long. For weeks she had planned on a vacation trip with her
+father, and now all her plans had been shattered.
+
+"Will you be staying long at Sunset Beach?" she asked the widow politely.
+
+"Probably a week," Mrs. Deline replied. "I've engaged a suite at the
+Crystal Inn. I'm sure I couldn't endure a camping trip. Mosquitoes--hard
+beds--cooking over a camp fire--it all seems rather difficult to me."
+
+"Oh, it will be fun to camp!"
+
+"I'm not so certain of it myself." Mr. Parker assisted the widow into the
+front seat. "Penny, why don't we ditch this camp stuff and try a hotel
+ourselves?"
+
+"No!" answered Penny fiercely.
+
+"It would be a far more sensible arrangement."
+
+"But I don't want to be sensible," Penny argued. "We've planned on this
+trip for weeks, Dad."
+
+"Oh, all right, if that's the way you feel about it," he gave in
+willingly enough. "Only I never did care much for the rough and tumble
+life myself. Are we ready to start?"
+
+"Just a minute," Penny requested. "I have to get my pocketbook from the
+house."
+
+She went indoors, her face as dark as a summer rain cloud. Mrs. Weems and
+Louise followed her in, corraling her in the kitchen.
+
+"Now Penny, just a word of advice," the housekeeper cautioned. "Mrs.
+Deline seems like a very nice woman. I trust that you'll be pleasant to
+her."
+
+"I don't see why Dad had to invite her! It's ruined everything!"
+
+"Aren't you being selfish?"
+
+"Maybe I am," said Penny. "But why should I be crammed back with the pots
+and pans and luggage while she sits up front with Dad?"
+
+"Mrs. Deline is your guest."
+
+"She's Dad's guest," Penny corrected. "Furthermore, I suspect she invited
+herself."
+
+"Whatever you think, I hope you'll keep your thoughts to yourself," Mrs.
+Weems said severely. "I'm really ashamed of you."
+
+The deep scowl disappeared from Penny's face and she laughed. Wrapping
+her arms about the housekeeper's ample waist she squeezed until it hurt.
+
+"I know I'm a spoiled brat," she admitted. "But don't worry. I'll pretend
+to like Mrs. Deline if it kills me."
+
+"That's much better, Penny. At any rate, you'll not be troubled with her
+company long. You'll reach Sunset Beach by nightfall."
+
+Penny made no reply. She turned to say goodbye to Louise.
+
+"Wish you were going along," she said wistfully. "A vacation won't seem
+fun without you."
+
+A staccato toot of the auto horn reminded Penny that her father and Mrs.
+Deline were waiting. Hurriedly she gathered up her purse.
+
+"Have a nice time," Louise said, kissing her goodbye. "And don't let Mrs.
+Deline get in your hair."
+
+Penny turned to make certain that Mrs. Weems was beyond hearing.
+
+"Don't worry about that, Lou," she whispered. "Mrs. Deline's already in
+my hair. What I'm really worried about is keeping her from building a
+nest in it!"
+
+
+
+
+ CHAPTER
+ 2
+ _STORMY WEATHER_
+
+
+For an hour the Parker car had rolled smoothly along the paved road
+enroute to Sunset Beach. In the back seat, firmly wedged between boxes
+and suitcases, Penny squirmed and suffered.
+
+"How much farther, Dad?" she inquired, interrupting an animated
+conversation he was having with Mrs. Deline.
+
+"Oh, about fifty miles," Mr. Parker tossed over his shoulder. "We can't
+make much time at thirty-five an hour."
+
+"How about lunch somewhere along the road?"
+
+"Well, should we take the time?" the publisher asked. He turned toward
+his companion. "What do you think, Mrs. Deline?"
+
+"Picnics always seemed stupid to me," she replied in a bored manner.
+"Perhaps we'll find a nice tea house along the way."
+
+"But Mrs. Weems prepared such a good lunch," Penny argued. "I thought--"
+
+"We can use the food after we make camp," Mr. Parker decided briskly. "A
+warm meal will be much better."
+
+Penny subsided into hurt silence. Since the party had left Riverview she
+felt that she had been pushed far into the background. Mrs. Deline had
+made no attempt to talk to her. On the other hand, the widow fairly
+hypnotized Mr. Parker with her dazzling smile and conversation.
+
+"Dad," Penny began, determined to get in a word, "just before you came
+home this afternoon, something queer happened."
+
+"That so?" he inquired carelessly.
+
+"Yes, I turned on the radio, and a station I'd never heard before came
+in. The announcer said: 'Attention Comrades, this is the Voice from the
+Cave.'"
+
+"Sounds like a juvenile radio serial."
+
+"Oh, but it wasn't, Dad! I'm sure it was an outlaw station. Then the
+announcer spoke very rapidly in a language I'd never heard before. It
+really sounded like code."
+
+"Sure you didn't imagine it? You know you do get ideas, Penny. Especially
+when you're on the prowl for a mystery to solve."
+
+"Aren't children quaint?" Mrs. Deline laughed.
+
+Penny's lips tightened, but by great effort of will she kept silent. A
+child indeed! She knew now that Mrs. Deline disliked her and that they
+had launched an undeclared war.
+
+"I heard the broadcast all right," she said. "For that matter, so did
+Mrs. Weems and Louise. But probably it's of no consequence."
+
+The subject was dropped. It was stuffy in the closed car and Penny
+presently rolled down a window. Immediately Mrs. Deline protested that
+the wind was blowing her hair helter-skelter. At a stern glance from her
+father, Penny closed the window again, leaving only a tiny crack for air.
+
+"All the way, please," requested Mrs. Deline.
+
+"Penny, you're being very, very difficult," Mr. Parker added.
+
+Penny rolled the window shut, but her blue eyes cast off little sparks of
+fire. As a rule, she was a very pleasant person, not in the least
+spoiled. In Riverview where she had lived for fifteen happy, eventful
+years, her friends were beyond count. Penny liked people and nearly
+everyone liked her. But for some reason, she and Mrs. Deline had taken an
+instant dislike to each other.
+
+"Maybe I'm jealous," Penny thought ruefully. "I shouldn't be, but Dad's
+all I have."
+
+Between Mr. Parker and his daughter there existed a deep bond of
+affection. Penny's mother was dead and the noted publisher had devoted
+himself to filling the great void in the girl's life. He had given her
+companionship and taught her to think straight. Knowing that she was
+dependable, he allowed her more freedom than most girls her age were
+permitted.
+
+Penny adored her father and seemingly had inherited his love of newspaper
+work. Upon various occasions she had helped him at the _Riverview Star_,
+writing and obtaining some of the paper's most spectacular front page
+stories. Only the past winter, following her father's severe illness, she
+had acted as editor of the _Star_, managing the paper entirely herself.
+
+"And now Dad and Mrs. Deline treat me as if I were a child!" she
+reflected resentfully.
+
+Though very much upset, Penny kept her thoughts to herself. Curling up
+with her head on a pile of blankets, she pretended to sleep.
+
+The car went over a hard bump. Penny bounced and opened her eyes. She was
+surprised to see that it had grown quite dark. The automobile was moving
+in a wide curve between long rows of pine trees.
+
+"What time is it?" she asked, pressing her face to the window.
+
+"Not so late," replied her father. "We're running into a rain storm. Just
+our luck."
+
+Dark clouds had entirely blotted out the late afternoon sun. Even as Mr.
+Parker spoke, several big raindrops splashed against the windshield.
+
+Soon the rain came down in such a thick sheet that the road ahead was
+obscured. Stopping suddenly for a crossroads traffic light, the car went
+into a slight skid. Mrs. Deline screamed in terror, and clutched Mr.
+Parker's arm.
+
+"Oh, can't we stop somewhere?" she pleaded. "I'm so afraid we'll have an
+accident."
+
+"Yes, we'll stop," Mr. Parker agreed. "The storm is certainly getting
+worse."
+
+A short distance ahead the party glimpsed a group of buildings. One was a
+filling station and beside it stood a small three-story hotel and tea
+room.
+
+"Doesn't look too bad," Mr. Parker commented, pulling up close to the
+door. "We'll have dinner and by that time the storm may be over."
+
+While Penny and Mrs. Deline went into the tea room, the publisher took
+the car next door to the filling station to have the tank refueled. He
+rejoined them soon, shaking the raindrops from his coat.
+
+"It's coming down harder than ever," he reported. "And we still have a
+long drive ahead of us."
+
+"Do you think we'll reach our camp site tonight, Dad?" Penny inquired
+anxiously.
+
+"We'll be lucky to get to Sunset Beach. As for making camp, that's out of
+the question."
+
+"Maybe it will stop raining soon," Penny ventured hopefully.
+
+Mr. Parker ordered dinner for the party and an hour was consumed in
+dining. The rain, however, showed no signs of slackening.
+
+"We could go on--" Mr. Parker said thoughtfully. "Of course, the roads
+are slippery."
+
+"Oh, please let's not venture out in this," Mrs. Deline pleaded before
+Penny could speak. "I know I am being silly, but I'm so afraid of an
+accident. Once I was in a car that overturned and I've never forgotten
+it."
+
+"There's no great hurry," Mr. Parker replied. "If we can't reach Sunset
+Beach tonight, I suppose we could stay here."
+
+Mrs. Deline did not comment upon the suggestion, but from the way she
+smiled, Penny was sure that the idea appealed to her. Taking her father
+aside, the girl urged him to try to drive on to Sunset Beach that night.
+
+"Our vacation is so short, Dad. Even now we'll lose almost a day in
+setting up camp."
+
+"We'll certainly push on if we can," he promised. "This storm complicates
+everything."
+
+For two hours the rain fell steadily. With the prospects anything but
+improved, Mr. Parker made inquiry as to lodging for the night. From the
+hotel keeper he learned that rooms already were at a premium.
+
+"We'll have to make up our minds soon," he reported to Penny and Mrs.
+Deline. "If we wait much longer we'll probably find ourselves sleeping in
+the lobby."
+
+"Then let's stay," the widow urged. "Please engage a room and a bath for
+me. Preferably one at the rear of the building away from the highway."
+
+"I'm afraid you'll have no choice," Mr. Parker told her regretfully.
+"We'll have to take what we can get."
+
+The publisher consulted with the hotel clerk, and returned to report that
+only two rooms remained available.
+
+"You and Penny will have to share one together," he explained. "I hope
+you won't mind."
+
+It was evident by the expression of Mrs. Deline's face that she minded a
+great deal. However, she consented to the arrangement and the luggage was
+taken upstairs. The door closed behind the bellboy. For the first time
+Penny and Mrs. Deline were left alone.
+
+"Such a cheap, dirty hotel!" the widow exclaimed petulantly. "And I do
+hate to share a room with anyone."
+
+Penny busied herself unpacking her over-night bag. Crossing to the
+window, she raised it half way.
+
+"Do put that down!" Mrs. Deline ordered. "I detest air blowing directly
+on me."
+
+Penny lowered the window.
+
+Mrs. Deline smoked a cigarette, carelessly allowing the ashes to fall on
+the bed. Getting up, she moved nervously about the room.
+
+"This place is so small it seems like a prison," she complained. "Why do
+you sit there and stare at me?"
+
+"I didn't realize I was staring," Penny apologized. "If you'll excuse me,
+I'll go to bed."
+
+Undressing quickly, she crawled beneath the covers. Mrs. Deline smoked
+still another cigarette and then began to prepare for bed. As she removed
+the jacket of her suit, Penny noticed that the woman wore a beautiful
+jade elephant pin.
+
+"Why, what an attractive ornament!" she exclaimed. "Is it a locket or
+just a pin?"
+
+"I bought it in China," the widow answered without replying to the
+question.
+
+"In China! Have you been there?"
+
+"Of course!" Mrs. Deline gave Penny an amused glance. Without removing
+the pin or offering to show it to the girl, she completed her
+preparations for bed.
+
+Just at that moment there came a light tap on the door.
+
+"Oh, Penny!" Mr. Parker called.
+
+"Yes, Dad, what is it?" Penny leaped out of bed.
+
+"I'm worried about the car keys," he called through the transom. "You
+didn't by chance see them after we left the dining room?"
+
+"Why, yes," Penny reassured him. "You left them lying on the table. I
+picked them up and forgot to tell you. They're here on the dresser. I'll
+hand them out."
+
+"No, never mind. Keep them. I was just afraid they were lost. Goodnight."
+
+Mrs. Deline glanced curiously at the key ring on the dresser. She
+remarked that she had not seen Penny pick it up.
+
+"You were talking to Dad at the time," the girl replied.
+
+Leaving the keys on the dresser, she leaped into bed again and settled
+herself for a comfortable sleep. Mrs. Deline presently turned out the
+light and took the other bed. For a time Penny was annoyed by voices from
+the hallway, then all became quiet. She slept.
+
+Much later Penny awoke. She stirred and rolled over. The rain had ceased
+and moonlight was flooding into the room. A beam fell directly across
+Mrs. Deline's bed, revealing a mass of crumpled sheets and covers.
+
+Penny stared, scarcely believing her eyes. The bed was empty.
+
+
+
+
+ CHAPTER
+ 3
+ _A JADE GREEN CHARM_
+
+
+Sitting up in bed, Penny gazed about the room. Mrs. Deline was not there
+and her clothes were gone from the chair where they had been placed
+earlier that night.
+
+"Queer," mused the girl.
+
+Jumping out of bed, she darted to the door. Though it had been carefully
+locked a few hours before, the latch now was off.
+
+Thoroughly puzzled, Penny switched on a light and glanced carefully
+about. Mrs. Deline's suitcase remained in the closet, but coat and hat
+were missing. And then Penny made an even more disturbing discovery. The
+car keys were gone from the dresser!
+
+"Why, I know I put those keys on the bureau just before I went to bed!"
+she told herself in dismay. "Now I wonder if that woman--" Ashamed of her
+thoughts, she muttered: "Guess I _am_ a suspicious brat!"
+
+Deeply mystified, she moved quickly to the window overlooking the parking
+lot and filling station. It was reassuring to see the Parker automobile
+standing where her father had left it earlier that night. But as she
+stood staring down into the dark, deserted yard, she was startled to
+observe a shadowy figure rounding a corner of the hotel.
+
+"Mrs. Deline!" she recognized the woman.
+
+Penny waited only long enough to see that the widow was walking straight
+toward the Parker sedan.
+
+"She intends to steal it!" thought the girl. "Why else would she take the
+keys?"
+
+Snatching dress and coat from a chair, Penny scrambled into them without
+taking time to remove her pajamas. She tucked up the unsightly legs of
+the garment and put on her shoes. Thus clad she ran downstairs through
+the semi-dark lobby to the side exit of the hotel.
+
+As she reached the outside door, she heard the blast of an automobile
+engine.
+
+"That's our car!" Penny thought, recognizing the sound of the running
+motor. "She'll get away before I can stop her!"
+
+The engine, evidently cold, sputtered a moment, then died.
+
+Hopeful that she might still get there in time, Penny raced across the
+parking lot. Reaching the car just as it started to move backwards, she
+jerked open the door.
+
+"Mrs. Deline!" she cried.
+
+Startled, the woman released the clutch so suddenly that the motor died
+again.
+
+"Where are you taking our car?" Penny demanded, sliding into the seat
+beside the widow.
+
+The girl's unexpected arrival seemed to completely unnerve Mrs. Deline.
+She lost composure, but only for an instant. Lighting a cigarette, she
+gazed at Penny with cold disdain.
+
+"I had intended to go for a little ride," she replied. "Any objections?"
+
+The question placed Penny on the defensive. "You shouldn't have taken the
+car without asking Dad," she said stiffly. "We barely have enough
+gasoline to reach Sunset Beach."
+
+"Oh, I had no thought of going far. I'll just drive a few miles and come
+back."
+
+"At this time of night? It must be nearly two o'clock."
+
+"I always enjoy night driving. Particularly if I am nervous and unable to
+sleep. Now run back to bed like a good child."
+
+Penny did not like the widow's tone of voice. She liked it less that Mrs.
+Deline ignored her hint that the car was not to be used. More than ever
+she was convinced that the woman had intended to steal the automobile.
+
+"I'm sorry," she said firmly. "I must ask you not to take the car without
+Dad's permission."
+
+"Well!" Mrs. Deline exclaimed indignantly. "You expect me to rap on your
+father's door at this time of night to ask if I may use the car!"
+
+"I don't see why you need to use the car at all."
+
+"Oh, you don't?" Mrs. Deline's tone was scornful. "Well, let me tell you
+this! I've already given you as much of an explanation as I intend to! I
+need the car."
+
+"I thought you said you only intended to go for a little drive--to quiet
+your nerves," Penny reminded her.
+
+"That's what I meant." Mrs. Deline tossed her cigarette through the open
+window and stepped on the car starter. "I intend to go too."
+
+Penny, equally determined, switched off the ignition.
+
+"Why, how dare you!" Mrs. Deline turned furiously upon the girl. "In all
+my life I never met such a spoiled child."
+
+"I don't mean to be rude, but I can't allow you to take the car."
+
+Mrs. Deline swung open the door on Penny's side of the seat. She reached
+as if to push the girl out of the car.
+
+Just then a man stepped from one of the hotel garages. Obviously he had
+been listening to the conversation, for he deliberately approached the
+car.
+
+"Anything wrong here?" he inquired.
+
+Penny recognized one of the night hotel clerks. She began to tell him of
+the disagreement between herself and Mrs. Deline.
+
+"This child doesn't know what she's talking about!" the widow declared
+irritably. "Mr. Parker doesn't mind if I use the car."
+
+"Then please ask him!" Penny challenged.
+
+"Why not allow me to do it for you," the hotel clerk offered. "Wait here
+and I'll call Mr. Parker. He can settle the entire matter."
+
+"No, don't bother him," Mrs. Deline decided suddenly. "I've changed my
+mind anyhow. After such a commotion I wouldn't enjoy a ride."
+
+"In any case, I'd prefer to call Mr. Parker," said the hotel man.
+
+"Do," urged Penny in deep satisfaction. "We'll wait here."
+
+"I'm going back to bed," Mrs. Deline announced, getting out of the car.
+
+She followed the hotel clerk into the building. Left in possession of the
+car, Penny reparked it and locked the doors. Then, feeling a trifle
+uneasy, she sauntered into the hotel.
+
+The lobby was deserted. Penny climbed the stairs, and in the hallway
+leading to her room, met her father and the hotel clerk. Summoned from
+bed, Mr. Parker garbed in dressing gown and slippers, looked more annoyed
+than alarmed.
+
+"Penny, what is this I hear?" he inquired. "I can't get the straight of
+the story."
+
+Penny drew a deep breath. "Well, it was this way, Dad. I awakened and
+discovered that Mrs. Deline had disappeared with the car keys."
+
+"Mrs. Deline!"
+
+"Yes, I think she meant to steal the car. But she explained that she only
+intended to borrow it for a night ride."
+
+"Anything wrong about that?"
+
+Penny regarded her father in blank amazement.
+
+"Why, Dad, would you borrow another person's car without asking?"
+
+"No, but Mrs. Deline probably didn't stop to consider the matter. No
+doubt she was too thoughtful to awaken you."
+
+"Thoughtful, my left eye! Dad, I'm sure Mrs. Deline meant to steal the
+car. Either that or she had a very important appointment--a meeting with
+someone she wasn't willing to tell us about."
+
+"Nonsense!" Mr. Parker exclaimed impatiently. "Penny, you made a serious
+mistake in refusing to allow Mrs. Deline to use the car. She is our guest
+and I'm afraid you were rude."
+
+"But Dad--"
+
+"You must apologize to her at once."
+
+Penny did not answer for a moment. She bent to tie her flapping shoe
+strings and took her time at the task. When she straightened, she said
+quietly:
+
+"All right, Dad. If you say so, I'll apologize. But I don't think I was
+wrong."
+
+"We'll not discuss it now, Penny. Suppose you turn the car keys over to
+me and go to your room."
+
+Penny gave up the keys and without another word went down the hall. Tears
+stung her eyes, but she brushed them away. She knew she had been
+unpleasant to Mrs. Deline. Nevertheless, she felt that her father had not
+been entirely just in his attitude.
+
+Entering the bedroom, she hesitated before turning on the light. Mrs.
+Deline had undressed and was in bed. She ignored the girl.
+
+"I--I guess I made a bad mistake," Penny began awkwardly. "I shouldn't
+have been so rude."
+
+Mrs. Deline rolled over in bed. Her dark eyes flashed and she made no
+effort to hide her dislike.
+
+"So you admit it?" she asked. "Well, we will forget the matter. Do not
+speak of it to me again."
+
+In silence Penny undressed and hung up her coat and dress. As she
+prepared to snap out the light, she noticed that Mrs. Deline still wore
+the jade elephant charm about her neck.
+
+"Aren't you afraid you'll break the chain?" she asked before she thought.
+"You forgot to take it off."
+
+Mrs. Deline raised herself on an elbow, fairly glaring at Penny.
+
+"Will you kindly worry about your own affairs?" she asked insolently.
+"I've had about all I can take from you in one night."
+
+"But I didn't mean anything personal."
+
+"Good night!" said Mrs. Deline with emphasis.
+
+Penny turned out the light and crept into her own bed. She felt beaten
+and hurt. It was easy to understand why Mrs. Deline disliked her, but her
+own attitude was bewildering.
+
+"I distrusted the woman the instant I met her," she reflected. "Perhaps I
+had no reason for it at first. Now I'm not so sure."
+
+Penny rolled over to face the window. Moonlight was flooding into the
+room. In the diffused light the girl could see Mrs. Deline plainly. The
+woman had propped herself up in bed and was fingering the jade green
+elephant charm which hung on its slender chain. Though Penny could not be
+certain, she thought the lid of the figure lay open and that Mrs. Deline
+quickly snapped it shut.
+
+"Good night, Mrs. Deline," she ventured, still trying to make amends.
+
+The widow did not answer. Instead she turned her back and pretended to
+sleep.
+
+
+
+
+ CHAPTER
+ 4
+ _NO CAMPING ALLOWED_
+
+
+Breakfast the next morning was a trying ordeal for Penny. Over the coffee
+cups Mr. Parker apologized to Mrs. Deline for what he termed his
+daughter's "inexcusable behavior."
+
+The widow responded graciously, quite in contrast to her attitude of the
+previous night. Without saying much, she conveyed the impression that
+Penny had been completely in the wrong, and was in fact, a spoiled child
+who must be humored.
+
+The journey on to Sunset Beach was equally unpleasant. Mr. Parker and
+Mrs. Deline seemed so absorbed in animated conversation, that they
+scarcely spoke or noticed Penny. Wedged between the luggage and the
+camping equipment, she indulged in self pity.
+
+"At least we'll get rid of Mrs. Deline when we reach Sunset Beach," she
+cheered herself.
+
+Presently the car rounded a wide curve in the road, and Penny caught her
+first glimpse of the seashore. Big waves were rolling in, washing an
+endless stretch of white sand.
+
+"Oh, isn't it beautiful!" she exclaimed, brightening. "I wish we were
+camping right on the beach instead of in the State Forest."
+
+"I fear the authorities wouldn't permit that," Mr. Parker laughed. "By
+the way, Penny, is your heart really set on this camping trip?"
+
+Penny gave him a quick look. "Yes, it is, Dad," she said briefly. "Why do
+you ask?"
+
+"Well, I was thinking that we'd be a lot more comfortable at one of the
+big hotels. We'd be right on the beach and--"
+
+"Oh, I was just talking when I said I'd like to camp on the beach," Penny
+cut in. "I'd like the State Forest much better."
+
+"Then we'll go there just as we planned," Mr. Parker said, sighing. "But
+you know I never was cut out for a rough and tumble life, Penny. I'm far
+from sure I'll make a good camper."
+
+The car rolled on along the ocean road, presently entering the little
+village of Sunset Beach. Normally a tourist center, the town now was
+practically deserted, and the Parkers had chosen it because it was within
+easy driving distance of Riverview. Nearly all of the fine hotels along
+the water front were closed. However, the Crystal Inn remained in
+operation, and it was there that Mrs. Deline had engaged a suite.
+
+The car swung into the driveway and halted in front of the hotel. An
+attendant did not come immediately so Mr. Parker himself unloaded the
+widow's luggage. Mrs. Deline gave him a dazzling smile as she bade him
+goodbye.
+
+"Oh, we'll not say goodbye just yet," Mr. Parker corrected. "Penny and I
+will camp only a short distance away. We'll run down to the beach often."
+
+"Do," urged Mrs. Deline. "I have no friends here and I'll be happy to see
+you."
+
+Mr. Parker carried the widow's luggage into the hotel. While he was
+absent, Penny moved up to the front seat. She tuned in a radio program,
+listening to it with growing impatience. Finally her father sauntered out
+of the hotel.
+
+"I nearly gave you up," Penny remarked pointedly.
+
+Mr. Parker slid behind the steering wheel and started the car. When they
+were driving along the ocean front road he said quietly:
+
+"Penny, I can't imagine what has come over you lately. You're not in the
+least like the little girl who was my pal and companion. Why have you
+been so unkind to Mrs. Deline?"
+
+"I just don't like her," Penny said flatly. "Furthermore, I distrust
+her."
+
+"You've acted very stupid and silly."
+
+"I'm sorry if you're ashamed of me," Penny replied glaring at her own
+reflection in the car mirror. "At any rate, I saved the car for you."
+
+"That accusation was ridiculous, Penny. Mrs. Deline is a wealthy woman
+who could buy herself a dozen cars in ordinary times. She merely gave in
+to a sudden whim."
+
+"Just what do you know about Mrs. Deline, Dad?"
+
+"Not a great deal," Mr. Parker admitted. "I met her at the club. She
+served as a special War correspondent in China, I believe. She has
+traveled all over the world and speaks a half dozen languages."
+
+"I never heard of her until she came to Riverview," Penny said with a
+sniff. "Nor did I ever see any of her writing in print. If you ask me,
+she's a phony."
+
+"Let's not discuss the subject further," Mr. Parker replied, losing
+patience. "When you're older, I hope you'll learn to be more gracious and
+charitable."
+
+Penny subsided into hurt silence. In all her life she could recall only a
+few occasions when her father had spoken so sternly to her. Close to
+tears, she studied the tumbling surface of the ocean with concentrated
+interest.
+
+In silence the Parkers drove through the village, stopping at a filling
+station to inquire the way to Rhett State Forest. Supplies were purchased
+at one of the stores, and by that time it was noon. At Mr. Parker's
+suggestion they stopped at a roadside inn for lunch. After that they
+drove on a half mile beyond the outskirts of Sunset Beach, past a tall
+lighthouse to the end of the pavement.
+
+"We follow a dirt road for a quarter of a mile to Bradley Knoll," Mr.
+Parker said, consulting directions he had jotted down on an envelope.
+
+"A mud road, you mean," Penny corrected, peering ahead at the narrow,
+twisting highway. "It really rained here last night."
+
+The car had no chains. Not without misgiving, Mr. Parker drove off the
+pavement onto the slippery road. The car wallowed about and at times
+skidded dangerously.
+
+"Once we reach the State park we'll have gravel roads," Penny said,
+studying a map.
+
+"_If_ we get there," Mr. Parker corrected.
+
+Barely had he spoken than the car went out of control. It took a long
+skid, turned crosswise in the road, and then the rear wheels slipped into
+a deep ditch. Opening the car door, Penny saw that the car was bogged
+down to the hub caps.
+
+Mr. Parker tried without success to pull out of the ditch. Alighting, he
+inspected the rear wheels which had spun deeper and deeper into the mud.
+
+"Not a chance to get out of here without help," he said crossly. "I'll
+have to find someone to give us a hand."
+
+Farther down the road stood a weatherbeaten farmhouse. Penny offered to
+go there to summon help, but her father insisted upon doing it himself.
+He presently returned with a farmer and a small tractor. After
+considerable difficulty the car was pulled out of the ditch.
+
+"How much do I owe you?" Mr. Parker asked the man.
+
+"Ten dollars."
+
+The amount seemed far too high for the service rendered, but Mr. Parker
+paid it without comment. His shoes were caked with mud, and so were the
+trouser legs of his suit. Only by an effort of will did he keep his
+temper under control.
+
+"Figurin' on camping in the Rhett Forest?" the farmer asked Mr. Parker.
+
+"That's right. Is it much farther?"
+
+"Only a little piece down the road. You'll strike gravel at the next
+corner. You can make it if you're careful. I don't calculate you'll have
+much fun camping in the Park though."
+
+"Why not?" asked Penny.
+
+"We've had a lot o' rain lately. The mosquitoes are bitin' something
+fierce. And the ground's mighty damp."
+
+"We have a floor to our tent," Penny said optimistically. "I think
+camping will be fun. I've always wanted to try it."
+
+The farmer started the tractor. "Then don't let me discourage you," he
+shrugged. "So long."
+
+Mr. Parker rejoined Penny in the car. "Why not call this whole thing
+off?" he suggested. "We could go to the hotel and--"
+
+"No, Dad! You promised me!"
+
+"All right, Penny, if that's the way you feel, but I know we're asking
+for punishment."
+
+By careful driving the Parkers reached the gravel road without mishap. At
+the entrance to the Rhett Park area they were stopped by a pleasant,
+middle-aged forest ranger who took down the license number of the car.
+
+"Be careful about your camp fire," he instructed. "Only last week several
+acres of timber were destroyed at Alton. We're not certain whether it was
+started by a camper or was a case of sabotage. In any case, one can't be
+too careful."
+
+"We will be," promised Mr. Parker.
+
+"Camp only in the designated sites," the ranger added. "I'll be around
+later on to see how you're getting along."
+
+Once beyond the gateway arch, Penny's sagging spirits began to revive.
+The road curled lazily between dense masses of timber fringed by artistic
+old-fashioned rail fences. Numerous signs pointed to trails that invited
+exploration.
+
+"Oh, Dad, it's really nice here!" she cried. "We'll have a wonderful
+time!"
+
+Presently the car came to an open space with picnic tables. There was a
+picturesque spot beside a rocky brook which looked just right for a camp
+site.
+
+"Let's pitch our tent here!" pleaded Penny. "You set it up while I cook
+supper."
+
+Mr. Parker unloaded the car and went to work with a will hammering the
+metal stakes of the umbrella tent. Penny busied herself sorting pots and
+pans and trying to get the gasoline stove started. Despite her best
+efforts she could not induce it to burn.
+
+In the meantime, Mr. Parker was having his own set of troubles. Three of
+the tent stakes were missing. Twice he put up the umbrella framework,
+only to have the entire structure collapse upon his head.
+
+"Penny, come here and help me!" he called. "I've had about enough of
+this!"
+
+Penny ran to her father's rescue, pulling the canvas from his head and
+shoulders. By working together they finally got the tent set up. Another
+half hour was required to put up the cots and make them.
+
+"Well, that job is done," Mr. Parker sighed, collapsing on one of the
+beds. "Such a life!"
+
+"Dad, I hate to bother you," Penny apologized, "but I can't start the
+stove. Do you mind looking at it?"
+
+Grumbling a bit, Mr. Parker went to tinker with the stove. Three-quarters
+of an hour slipped away before he succeeded in coaxing a bright flame.
+
+"All this work has given me a big appetite for supper," he announced.
+"What are we having, Penny?"
+
+"Steaks."
+
+"Sounds fine."
+
+"I forgot the salt though," Penny confessed, slapping the meat into a
+frying pan.
+
+The burner was too hot. While Penny had her back turned and was opening a
+can of beans, the steaks began to scorch. Mr. Parker tried to rescue
+them. In his haste he seized the hot skillet handle and burned his hands.
+
+"Oh, Dad, I'm so sorry!" Penny sympathized. "I guess the steaks are
+practically ruined too."
+
+"Anything else to eat?" the publisher asked, nursing his blistered hand.
+
+"Beans."
+
+"Beans!" Mr. Parker repeated with bitter emphasis. "Oh, well--dish them
+up."
+
+Penny was serving the food on tin plates when a car drove up and stopped.
+A ranger climbed out and walked over to the tent.
+
+"What's the idea, camping here?" he demanded. "Can't you read signs?"
+
+"We didn't see any sign," said Penny.
+
+The ranger pointed to one in plain sight tacked on the trunk of a tree.
+It read:
+
+"Restricted Area. No Camping Permitted."
+
+"You can't stay here," the ranger added. "You'll have to move on."
+
+Penny and her father gazed at each other in despair. After all the work
+they had done, it didn't seem as though they could break camp.
+
+"Any objections if we stay here until morning?" Mr. Parker requested.
+"We've had a pretty hard time of it getting established."
+
+The ranger looked sympathetic but unmoved.
+
+"Sorry," he said curtly. "Regulations are regulations. You may finish
+your supper if you like, then you must move on. The regular camp site is
+a quarter of a mile farther up the road."
+
+
+
+
+ CHAPTER
+ 5
+ _OVER THE AIR_
+
+
+The ranger's order so discouraged Penny and her father that they lost all
+zest for supper. Too weary for conversation, they tore up the beds,
+repacked the dishes, and pulled the tent stakes.
+
+"I've not worked so hard in years," Mr. Parker sighed. "What a mistake to
+call this a vacation!"
+
+"Perhaps it won't be so hard once we get settled," Penny said hopefully.
+"After all, we've had more than our share of bad luck."
+
+Bad luck, however, continued to follow the campers. In the gathering
+darkness, Penny and her father had trouble finding the specified camp
+ground. It was impossible to drive a car into the cleared space, so they
+were forced to carry all of the heavy luggage and equipment from the
+automobile to the camp site.
+
+By that time it was quite dark. Mr. Parker misplaced one of the tent
+stakes and could not find it without a lengthy search. As he finally
+drove it in, he hammered his thumb instead of the metal pin.
+
+"Drat it all! I've had enough of this!" he muttered irritably. "Penny,
+why not give it up--"
+
+"Oh, no, Dad!" Penny cut in quickly. "Once we get the tent up again,
+we'll be all right. Here, I'll hold the flashlight so you can see
+better."
+
+Finally the tent was successfully staked down, though Mr. Parker
+temporarily abandoned the idea of putting up the front porch. Penny set
+up the cots again and made the beds.
+
+"Hope you packed plenty of woolen blankets," Mr. Parker commented,
+shivering. "It will be cold tonight."
+
+Penny admitted that she had brought only two thin ones for each bed. "I
+didn't suppose it could get so cold on a summer night," she confessed
+ruefully.
+
+Worn by his strenuous labors, Mr. Parker climbed into the closed car to
+smoke a cigar. Penny, finding the dark tent lonesome, soon joined him
+there. She switched on the car radio, tuning in an orchestra. Presently
+it went off the air so she dialed another station. A strange jargon of
+words which could not be understood, accosted her ears.
+
+"Hold that, Penny!" exclaimed Mr. Parker.
+
+"What station can it be?" Penny speculated, peering at the luminous dial.
+"It sounds like a short wave broadcast. Must be a station off its wave
+band."
+
+She and her father listened intently to the speaker who had a resonant,
+baritone voice. Not a word of the broadcast could they understand.
+Obviously a message was being sent in code.
+
+"Dad, that sounds like the same station I heard yesterday!" Penny broke
+in. "Where can it be located?"
+
+"I'd like to know myself."
+
+Penny glanced quickly at her father. His remark, she thought, had
+definite significance. Before she could question him, the strange jargon
+ceased. The deep baritone voice concluded in plain, slightly accented
+English: "This is the Voice from the Cave, signing off until tomorrow
+night. Stand by, Comrades!"
+
+"That was no regular station," Penny declared, puzzled. "But what was
+it?"
+
+Mr. Parker reached over to turn off the panel switch. "It was an outlaw
+station," he said quietly. "The authorities have been after it for
+weeks."
+
+"How did you learn about it?"
+
+"Through various channels. Most outlaw radio stations can be traced quite
+easily by the use of modern radio-detecting devices. The enemy agent who
+operates this station is a particularly elusive fellow. Just when the
+police are sure they have him, he moves to another locality."
+
+Penny was silent a moment and then she said:
+
+"You seem to know quite a bit about this mysterious Voice, Dad."
+
+"Naturally I've been interested in the case. If the police catch the
+fellow it will make a good story for the _Star_."
+
+"Where is the station thought to be located, Dad?"
+
+"Oh, it moves nightly. The fellow obviously has a portable broadcasting
+outfit."
+
+"But isn't the general locality known?"
+
+Mr. Parker smiled as he knocked ashes from his cigar.
+
+"Authorities seem to think that it may be somewhere near here. Sunset
+Beach has countless caves, you know."
+
+"Really?" The information excited Penny. "You never told me that before,
+Dad. And I suspect that you're keeping a lot of other secrets from me
+too!"
+
+"Sunset Beach's caves are no secret. They're part of the tourist
+attraction."
+
+"All the same you never mentioned them, Dad. I thought it was odd that
+you chose this place for a vacation. Now I'm beginning to catch on."
+
+Mr. Parker pretended not to understand.
+
+"Isn't it true that you came here to do a bit of investigation work?"
+Penny pursued the subject relentlessly.
+
+"Now don't try to pin me down," Mr. Parker laughed. "Suppose we just say
+we came here for a vacation."
+
+Penny eyed her father quizzically. From the way he sidestepped her
+questions she was certain that he had more than a casual interest in the
+outlaw radio station.
+
+"Dad, will you let me help you?" she pleaded eagerly.
+
+"Help me?" Mr. Parker joked. "Why, you seem to think that I'm a
+Government investigator in disguise!"
+
+"You don't deny that you came here largely because of your interest in
+that station?"
+
+"Well, I may be a tiny bit interested. But don't jump to conclusions,
+young lady! It doesn't necessarily follow that I have set out to track
+down any enemy agent single handed." Mr. Parker brought the discussion to
+an end by opening the car door. "I'm dead tired, Penny. If you'll excuse
+me, I'll turn in."
+
+After her father had gone to the tent, Penny remained for a while in the
+car. Soberly she stared at the stars and thought over what she had
+learned.
+
+"I don't care what Dad says," she reflected, "he came here to find that
+radio station! But maybe, just maybe, I'll beat him to it!"
+
+
+
+
+ CHAPTER
+ 6
+ _BREAKFAST BLUES_
+
+
+Penny awoke next morning to find the tent cold and damp. She rolled over
+on the hard cot and moaned with pain. Every muscle in her battered body
+felt as if it had been twisted into a knot.
+
+Swinging her feet to the canvas floor, she pulled away the curtain to
+peer at her father's cot. It was empty.
+
+"Guess I've overslept," she thought. "Hope Dad's started breakfast."
+
+Penny dressed quickly, cringing as she pulled on damp shirt and shorts.
+Dew lay heavy upon the tent and the grass outside was saturated. She
+walked gingerly as she picked her way toward the parked car.
+
+Mr. Parker had set up a portable table nearby and was tinkering with the
+gasoline stove. He was unshaven and looked very much out of sorts.
+
+"Hi, Dad!" Penny greeted him with as much cheer as she could muster.
+"What are we having for breakfast?"
+
+"Nothing, so far as I can see! This stove is on strike again. I've tried
+for half an hour to get it started."
+
+Penny climbed into the car to use the mirror. The sight of her face
+horrified her. One cheek was blotched with ugly red mosquito bites, there
+were dark circles under her eyes, and her hair hung in strings.
+
+"If anyone ever gets me on another camping trip I'll be surprised!" Mr.
+Parker exclaimed. He slammed the stove down on the table. "I'm through
+monkeying with this contrary beast!"
+
+"Oh, Dad, such a temper," Penny chided, giggling despite her own
+discouragement.
+
+"Suppose you suggest how we're to eat."
+
+"Well, there's cold breakfast food with canned milk." Penny burrowed deep
+in a box of supplies stored in the car. "Two soft bananas. No coffee, I'm
+afraid."
+
+"Wonderful!" Mr. Parker said grimly. "Well, bring on the bird food."
+
+Penny set the table and dished up the dry breakfast cereal.
+
+"At least we have beautiful scenery," she remarked as she sat down to the
+dismal repast with her father. "Just look at those grand old trees."
+
+"The place is all right. It's camping that has me tied in a knot. Now at
+the Crystal Inn we could be comfortable--right on the beach too."
+
+"No," Penny said, though not very firmly. "We'll like it here after we
+get adjusted."
+
+"Need any supplies today?" Mr. Parker asked abruptly.
+
+"Yes, we'll have to have fresh meat and milk. I forgot salt too and
+bread."
+
+"I'll drive down to Sunset Beach and get the things. May as well take the
+stove along too and try to have it repaired."
+
+"That might be a good idea," Penny admitted, though with reluctance.
+"Don't be gone long, will you? I thought we might explore some of the
+trails."
+
+"Oh, there's plenty of time for that."
+
+Mr. Parker was noticeably cheerful as he stowed the portable stove in the
+car and drove away. Not without misgiving Penny watched him go. She
+remained somewhat troubled as she washed the breakfast dishes at the
+brook and struggled with the beds. The camping trip hadn't worked out as
+she had hoped and expected. So far it had been all work and no fun.
+
+"Dad was up to something when he skipped out of here so fast," she mused.
+"Wonder why he doesn't come back?"
+
+The sun rose high above the trees, drying the grass and tent. Penny went
+for a short hike in the woods. She returned to find that her father still
+had not returned.
+
+Just then a car rattled up the twisting road. Recognizing the same ranger
+who had caused so much trouble the previous night, Penny prepared herself
+for further blows. However, the government man was all smiles as he
+pulled up not far from the umbrella tent.
+
+"Just dropped by to see if you're getting along all right," he greeted
+her in a friendly way. "Everything Okay?"
+
+"I wouldn't venture such a rash statement as that," Penny answered, her
+face downcast.
+
+Because the ranger, whose name was Bill Atkins, seemed to have a genuine
+interest, she found herself telling him all about her troubles.
+
+"Why, you've not had a decent meal since you came here!" he exclaimed,
+climbing out of the car. "Maybe I can help you."
+
+"Can you wave a magic wand and produce hot food?"
+
+"We'll see," laughed the ranger. "Gasoline stoves are more bother than
+they're worth in my opinion."
+
+As Penny watched in amazed admiration he built a good fire which soon
+made a bed of glowing cherry red coals.
+
+"How about a nice pan of fish fried to a crisp brown?" the ranger tempted
+her. "I caught a string of them this morning. Beauties!"
+
+From the car he brought a basket of fat trout, already dressed and ready
+for cooking. Without asking Penny for anything, he wrapped them in corn
+meal, salted each fish and let it sizzle in hot butter.
+
+"Do you always travel with your car equipped like a kitchen cabinet?"
+Penny joked. Crouching beside the fire, she barely could take her eyes
+from the food.
+
+"Not always," the ranger laughed. "I've been on an overnight trip.
+Usually have the fixings of a meal with me though."
+
+While the fish slowly sizzled, Bill put on a pot of coffee and fried
+potatoes. He accomplished everything with such ease that Penny could only
+watch dumbfounded.
+
+"Guess you and your father considered me an old crab last night," he
+remarked. "Sometimes we hate to enforce the rules, but we have to treat
+everyone alike. If we allowed folks to camp wherever they pleased the
+danger of forest fire would be greatly increased."
+
+"You're right, of course. Have you had any fires this season?"
+
+"Not here." Deftly the ranger dished up the potatoes and crisply browned
+fish. "Plenty of them farther South. Not all caused by carelessness of
+campers either."
+
+Penny was quick to seize upon the remark. "Sabotage?" she questioned.
+
+"That's what we think," the ranger nodded. He poured two cups of
+steaming, black coffee. "Fact is, enemy agents have made quite a few
+attempts to set fire to our forests. Nearly always they're caught, but
+that doesn't mean we dare let up our vigilance."
+
+Penny ate every morsel of the food, praising the ranger highly for his
+cooking ability.
+
+"I wish Dad could have had some of this fish," she added. "He went down
+to Sunset Beach for supplies and for some reason hasn't returned."
+
+"I'll have to be on the road myself," the ranger declared, getting up
+from the ground. "I'm due in town at twelve o'clock and it's nearly that
+now."
+
+"You're driving to Sunset Beach?"
+
+"Yes, want to ride along?"
+
+Penny debated briefly. "Wait until I get my coat," she requested. "It's
+lonesome here alone. Anyway, I want to learn what's keeping Dad."
+
+The park road had dried considerably, but even so the car skidded from
+side to side until it reached the paved highway. At Sunset Beach, the
+ranger dropped Penny off at the postoffice. Rather at a loss to know what
+to do with herself, she wandered about the half-deserted streets in
+search of her father. He was not at any of the stores, nor did inquiry
+reveal his whereabouts.
+
+"Perhaps he's sunning himself on the beach," she thought.
+
+A boardwalk led over the dunes to the water front. The tide was at ebb,
+revealing a long, wide stretch of white sand strewn with shells and
+seaweed. Penny paused to gaze meditatively upon the wind-swept sea. For a
+time she watched the waves break and spill their foam on the sandy shore.
+Then she walked slowly on toward the imposing Crystal Inn.
+
+Approaching the private beach area, Penny met only a few persons, mostly
+soldiers on furlough with their girls. There were no bathers for a sharp,
+cool wind blew off the water.
+
+"Sunset Beach is nice," thought Penny, "but it's lonesome."
+
+At the Crystal Inn there was more activity. Tennis courts were in use and
+so was the swimming pool. Penny circled the well-kept grounds, not
+intending to enter the building. However, as she drew near, her attention
+was drawn to the flagstone terrace overlooking the formal garden. Though
+it was set with tables there were not many diners.
+
+Suddenly Penny stopped short, scarcely believing her eyes. At one of the
+tables near the stone railing sat her father with Mrs. Deline.
+
+
+
+
+ CHAPTER
+ 7
+ _THE BEARDED STRANGER_
+
+
+Penny's first thought upon seeing her father and Mrs. Deline was to steal
+quietly away. Then amazement and injury gave way to a feeling of
+indignation. Perhaps her father had a perfect right to lunch with Mrs.
+Deline, but it was inconsiderate of him to so completely forget his own
+daughter.
+
+"I might just as well be an orphan!" Penny sighed. "Well, we'll see!"
+
+Stiffly she marched across the lawn to the railed-in hotel veranda. Her
+father saw her coming. His look of surprise changed to one of guarded
+welcome.
+
+"Come up and have lunch with us," he invited. "The food here is quite an
+improvement on what we've been having at camp."
+
+Penny could find no outside entranceway to the terrace. To Mrs. Deline's
+horror and her father's amusement, she climbed over the stone railing.
+
+"Dad," Penny began, ignoring the widow except for a curt nod, "I was just
+about ready to get out a search warrant for you."
+
+Mr. Parker drew another chair to the table for his daughter. Her hair was
+none too well combed, she wore no stockings, and the coat did not
+entirely cover her camp costume. By contrast Mrs. Deline was perfectly
+turned out in tailored tweed suit with a smart little hat of feathers.
+Though the woman said nothing, her gaze was scornful as she appraised
+Penny.
+
+"What shall I order for you?" Mr. Parker asked, signaling a waiter.
+
+"Nothing, thank you." Penny was coldly polite. "I had a very fine lunch
+at camp, thanks to one of the rangers."
+
+"I'm sorry I didn't get back," Mr. Parker apologized. "It took a long
+while to have the stove repaired. Then I met Mrs. Deline and--"
+
+"Oh, I understand," Penny broke in. "The point is, when, if ever, are you
+coming back to camp?"
+
+"Why, right now I suppose. We've finished our luncheon."
+
+The waiter had come to the table. Mr. Parker asked for the bill, paid it,
+and arose. As he bade Mrs. Deline goodbye, he remarked that he probably
+would see her again soon.
+
+Walking to the hotel parking lot where Mr. Parker had left the car,
+neither he nor Penny had much to say. Not until they were driving through
+the village was the subject of Mrs. Deline mentioned.
+
+"I don't see why you can't be a bit nicer to her," Mr. Parker commented.
+"You scarcely spoke a word to her."
+
+"Did she say anything to me?"
+
+"Well, I don't recall."
+
+"I've treated Mrs. Deline just as well as she treats me!" Penny defended
+herself. "I'll admit I don't like her."
+
+"And you show it too."
+
+"Maybe I do, but she has no business taking so much of your time."
+
+"So that's where the shoe pinches," chuckled Mr. Parker. "My little girl
+is jealous."
+
+"The very idea!"
+
+"Mrs. Deline is brilliant--a highly educated woman and I enjoy talking to
+her," Mr. Parker said thoughtfully. "I assure you it's no more serious
+than that."
+
+Penny moved close to her father and squeezed his arm.
+
+"We've been pals for such a long while," she said wistfully. "If anything
+ever should come between us--"
+
+"Penny, you're positively morbid!" her father interrupted. "Of course
+nothing ever will come between us! Now let's talk of more cheerful
+subjects."
+
+"Such as?"
+
+"I've been thinking, Penny. You need a friend, someone to pal around
+with."
+
+"You're the only friend I need, Dad."
+
+"I mean someone your own age, Penny. Why not send for Louise Sidell? I'll
+gladly pay her train fare."
+
+"It would be fun having Lou here."
+
+"Then it's settled. We'll send a wire now." Mr. Parker turned the car
+around and drove to the local telegraph office.
+
+Before Penny could change her mind, the message was sent. Not until long
+after she and her father had returned to the park did it occur to her
+that unwittingly she might have fashioned her own undoing. Though camping
+would be far more interesting with Louise to share her experiences, it
+also would give her father added opportunity to see Mrs. Deline.
+
+"Maybe he didn't think of that angle," Penny reflected uneasily. "I'll
+keep it to myself."
+
+The following day Mr. Parker spent the entire day in camp. With the
+gasoline stove in working order, hot meals were prepared though not
+without endless effort. There were dishes to wash, beds to make, and by
+the time the tasks were done, neither Penny nor her father had any energy
+left for hiking.
+
+The second day was much easier. However, with more free time, Mr. Parker
+became increasingly restless. He missed his morning paper and was
+dissatisfied with the skimpy news reports that came in over the radio.
+Penny was not surprised when he mentioned that he would walk down to
+Sunset Beach.
+
+"Mind if I go with you?" Penny asked quickly.
+
+"Of course not," her father answered. "Why should I?"
+
+At Sunset Beach a call at the local telegraph office disclosed a message
+for Penny which had been held for lack of an address. The wire was from
+Louise and read:
+
+"ARRIVING AT SUNSET BEACH THURSDAY ON THE 12:30 PLANE. HOLD EVERYTHING."
+
+"Thursday!" Penny cried, offering the telegram to her father. "That's
+tomorrow! My, will I be glad to see Lou! This place has been like a
+morgue without her."
+
+"I imagine the town will brighten up quite a bit within the next few
+days," Mr. Parker said, a twinkle in his eye. "In fact, Louise may not be
+the only new arrival."
+
+"Is someone else coming to see us?"
+
+Mr. Parker would not answer her many questions. "Wait and see," he
+teased.
+
+Since arriving at Sunset Beach Penny had been eager to visit the
+lighthouse located on Crag Point. Noticing that the tide was low, she
+suggested to her father that they go there together.
+
+"Too long a walk," he complained. "You run along by yourself. I'll sun
+myself on the beach."
+
+Leaving her father, Penny started off alone. The sun was warm and there
+were a number of bathers splashing about in the surf. A long row of
+picturesque cottages lined the water front. They thinned out as she went
+farther up the beach, and presently there were no habitations, only
+desolate, wind-blown sand.
+
+Midway to the lighthouse, Penny met a man of early middle age who carried
+fishing rod and creel. He stared at her, hesitated, then paused to speak.
+
+"I notice you're going toward Crag Point," he remarked pleasantly. "Are
+you a stranger to this locality?"
+
+Penny admitted that she was.
+
+"Then perhaps you haven't been told that the Point is a dangerous place
+to be at high tide."
+
+"No, I hadn't heard."
+
+"The Point is very nearly covered at that time," the stranger explained.
+"There's no danger at the present moment, of course."
+
+"How long will I have here?"
+
+"Oh, several hours," the stranger replied. "There's no cause for alarm if
+you just keep watch of the tide."
+
+Penny thanked the stranger and walked on toward the lighthouse. The
+structure rose to a height of seventy-five feet above the beach and was
+reached by means of a narrow little iron stairway.
+
+No one was about the premises as Penny approached. However, as she
+started up the iron steps, a door far above her head opened. A burly,
+stout man whose face was browned by wind and sun, peered down at her.
+
+"You can't come up here!" he shouted. "No visitors are allowed!"
+
+"Oh," Penny murmured, retreating a step. "I didn't know. I only wanted to
+see the tower."
+
+"No visitors," the keeper of the light repeated. "War regulations."
+
+The rule seemed a reasonable one, but after such a long hike, Penny was
+disappointed. Walking back to the main section of the beach, she looked
+about for her father. He had disappeared.
+
+"I'll bet a cookie he's at the Crystal Inn!" she thought indignantly.
+
+But Penny could not find her father there nor at any other place along
+the water front. After an hour's search she decided that he must have
+returned to camp. Returning there, she approached the tent, noticing that
+the flap was closed, though not buttoned as she had left it.
+
+"Dad must be here," she thought.
+
+Drawing nearer she could see movement within the tent as someone brushed
+against the canvas walls.
+
+"Oh, Dad!" she called.
+
+There was no answer. But the next instant a man in rough garments and
+straw hat rushed out of the tent. Penny never before had set eyes upon
+him. She was so astonished that she gained only a fleeting impression of
+the bearded stranger. Seeing her, he thrust some object beneath his coat
+and fled into the woods.
+
+
+
+
+ CHAPTER
+ 8
+ _KEEPER OF THE LIGHT_
+
+
+Recovering from astonishment, Penny darted to the tent and jerked open
+the flap. The beds had been torn apart. Her purse, hidden beneath the
+pillow, was gone. Suitcases lay open on the canvas floor.
+
+"That man was a thief!" she thought angrily.
+
+Too late, she tried to determine which direction he had taken. She could
+hear no sound of crackling leaves or running feet.
+
+"He's lying low," she told herself. "No use chasing him. I never could
+find him among the trees."
+
+Thoroughly incensed, she went back to the disordered tent. A preliminary
+check revealed that besides the pocketbook, a pair of her father's shoes
+and a sweater had been taken.
+
+"Lucky I didn't have much money in my purse," Penny congratulated
+herself. "It was a good leather pocketbook though, and I hate to lose
+it."
+
+Going outside, she discovered other losses. The supply of groceries had
+been ransacked. Bread was gone, several oranges and a tin of cold meat.
+
+"That fellow was hungry," Penny reflected. "Probably some shiftless
+person who isn't willing to work for a living."
+
+Entering the tent again, she busied herself making the beds and repacking
+the suitcases. As she finished the task, she heard footsteps outside.
+Fearful that the thief had returned, she jerked open the canvas flap. It
+was her father who had arrived.
+
+"Oh, Dad, I'm glad you're back!" she exclaimed, rushing out to meet him.
+"We've been robbed!"
+
+"What?"
+
+Penny told him how she had frightened away the bearded stranger.
+
+"That's bad," Mr. Parker said, frowning. "I didn't suppose there was
+another camper within miles of us."
+
+"This man didn't look like a camper, Dad. He wore dirty, mussed clothing
+and a beard of at least a week's growth."
+
+"How old a fellow?"
+
+"Why, he looked young to me. And he ran like a young person."
+
+"We'll report it to the ranger," Mr. Parker said, entering the tent to
+check over his belongings. "Probably never will get any of our things
+back though."
+
+"The ranger may know who the fellow is, Dad."
+
+"That's possible," Mr. Parker admitted. "Penny, I'm glad Louise is coming
+tomorrow. I certainly don't like the idea of your remaining here in camp
+alone."
+
+"Then why don't you stay with me?" Penny countered instantly.
+
+"Well, I'm planning on being rather busy."
+
+"With Mrs. Deline."
+
+"Penny, you're impossible!"
+
+"Weren't you with her today? I looked everywhere for you."
+
+"Mrs. Deline and I did go for a little walk. No harm in that, is there?"
+
+"It all depends upon your viewpoint," Penny said loftily. "Personally, I
+consider her about as harmless as a Grade A rattler!"
+
+"Penny, enough of such talk!"
+
+"Okay," she returned grimly, "but never say I didn't warn you."
+
+"I was about to tell you," Mr. Parker resumed, "that I expect to be busy
+the next few days helping local authorities trace that outlaw radio
+station we heard on the air."
+
+"Oh!"
+
+"In fact, Army experts are being sent here to aid in the work. My days
+will be pretty well tied up."
+
+"I'm sorry, Dad," Penny said contritely. "Naturally I thought--"
+
+"I'm afraid your trouble is that you don't stop to think," Mr. Parker
+lectured. "Please, will you forget Mrs. Deline?"
+
+"I promise not to bother you about her again, Dad."
+
+"Good!" Mr. Parker awkwardly patted his daughter's hand. "I realize
+you've had an unpleasant time of it so far, Penny. But things should pick
+up after Louise arrives."
+
+"And that other surprise you hinted about?"
+
+"Oh, you'll have to wait and see," Mr. Parker smiled. "However, I promise
+you that what's coming really will prove a pleasant surprise."
+
+Though Penny kept up a running fire of questions, her father would tell
+her no more. From a few hints he dropped, she gathered that he was
+expecting a visitor within a day or so. That rather disappointed her, for
+with the exception of Louise, she could think of no one she particularly
+wanted to see at Sunset Beach.
+
+Later that day when a forest ranger stopped at camp for a few minutes,
+Mr. Parker reported the theft of food and clothing to him.
+
+"So the thief was a young man with a beard?" the ranger pondered. "Don't
+know of anyone in the area answering such a description. We'll certainly
+be on the watch for him."
+
+Penny and her father expected to hear no more from the matter. Toward
+sundown, however, the same ranger returned to camp, bringing the missing
+pocketbook. It was stripped of money but still contained a compact and
+various toilet articles.
+
+"Where did you find the purse?" Penny inquired eagerly.
+
+"On the Beech Trail not far from here."
+
+"Then it was dropped on purpose?"
+
+"Apparently it was. I followed the trail for a quarter of mile, then lost
+the fellow when he took to the brook."
+
+"Rather a smart fellow to think of that," commented Mr. Parker
+thoughtfully. "Perhaps he wasn't an ordinary snatch-thief after all."
+
+The ranger offered no comment. As he turned to go, he did assure Penny
+again that every effort would be made to capture the culprit.
+
+"If the fellow still is in the park we'll get him," he declared. "Don't
+you worry about that."
+
+With the coming of dusk a penetrating chill settled over the camp. Even
+the hot supper of steak and potatoes that Penny prepared failed to
+sufficiently warm the two tenters. They did the dishes and then, not
+wishing to go to bed, sought the enclosed car for heat.
+
+"It's starting to rain," Mr. Parker observed as a few drops splashed
+against the windshield. "Looks as if we're in for another siege of it."
+
+"And Louise is due tomorrow," Penny sighed. "Unless the weather improves
+I'd not blame her one bit if she turns right around and starts back to
+Riverview."
+
+The rain came down steadily with a promise of continuing throughout the
+night. Mr. Parker read a day-old newspaper by the light in the car,
+grumbling because the news was so old. Presently he switched on the
+radio, trying without success to tune in the outlaw station which had
+been heard previously at the same hour.
+
+"No luck," he commented. "Reception must be poor tonight, or the station
+has changed to another time. Probably it's shifted to a different
+locality too."
+
+"Dad, isn't it true that the operator of that secret station is an enemy
+agent?" Penny asked curiously.
+
+"It's a possibility."
+
+"Why not tell me all about it?"
+
+"Nothing to tell yet, Penny. Confidentially I'll admit I came here hoping
+to help State authorities find the station. So far I've accomplished
+nothing."
+
+"What clues have you gained?"
+
+"Now Penny, don't quiz me," Mr. Parker laughed. "I'll tell you everything
+as soon as I'm free to do so."
+
+"In the meantime, maybe I'll find out for myself!" Penny hinted. Abruptly
+swinging open the car door, she bolted through the rain to the tent.
+
+Breakfast the next morning was a more cheerful meal than had been
+expected. During the night the rain had ceased and a hot morning sun soon
+dried out the drenched canvas. Mr. Parker prepared coffee, eggs and
+bacon, an unbelievable example of perfect cooking.
+
+"Dad, I didn't think you had it in you!" Penny praised as she sat down on
+a camp stool beside him. "Maybe you'll develop into a real camper after
+all."
+
+"Not if I have anything to say about it." Grinning, Mr. Parker dropped
+two plump fried eggs on his daughter's plate and took the remaining four
+for himself. "This life could be worse though."
+
+"Dad, what time shall we start for the airport?"
+
+Mr. Parker poured himself a cup of coffee and then answered: "Afraid I
+won't be able to go with you, Penny."
+
+"But Dad! Louise will be expecting you."
+
+"It's not me she wants to see," Mr. Parker corrected. "I have an
+important engagement I can't break."
+
+Penny glanced quickly up. She was tempted to ask her father if he
+intended to see Mrs. Deline. Recalling that she had made her father a
+promise, she wisely withheld comment. Instead she asked if she might use
+the car.
+
+"By all means," he consented. "Just go easy on the gasoline."
+
+Breakfast over, dishes were dispatched and the camp put in order. By
+eleven o'clock Penny and her father were in Sunset Beach.
+
+"Drop me anywhere," Mr. Parker instructed vaguely.
+
+Leaving her father on a street corner, Penny drove slowly toward the
+airport a mile and a quarter away. There was little travel on the winding
+highway which curled along the beach. A government jeep whizzed past and
+two soldiers shouted and waved. Penny waved back.
+
+There was no need to hurry for Louise's plane was not yet due. Penny took
+her time and enjoyed the ocean scenery. The tide was coming in and gulls
+free-wheeled over the waves, dipping down at intervals in search of food.
+
+Gazing along the deserted beach, Penny was startled to see a familiar
+feminine figure hastening toward the lighthouse on Crag Point. The woman
+wore a white scarf that half obscured her face, yet the girl easily
+recognized her.
+
+"Mrs. Deline!" she thought, idling the car. "She's certainly going to the
+lighthouse! I wonder if that gruff old keeper will drive her away as he
+did me?"
+
+Curious to learn what would happen, the girl drew up at the side of the
+road. Mrs. Deline was too far away to observe the automobile. Intent only
+upon her own affairs, she walked swiftly along the beach until she
+reached the base of the lighthouse.
+
+"Now to see the fun!" chuckled Penny.
+
+The keeper had appeared on the platform and was gazing down upon the
+visitor. He called something to the woman that Penny could not hear. But
+to her amazement, Mrs. Deline started up the iron stairway.
+
+Penny waited expectantly. She was certain that the keeper of the light
+would order Mrs. Deline away. Instead, he greeted her with a hearty
+handshake as if they were old friends. They entered the lighthouse tower
+room together, and the heavy door closed behind them.
+
+
+
+
+ CHAPTER
+ 9
+ _A SURPRISE FROM THE SKY_
+
+
+"Well, if that isn't strange!" Penny muttered. "I wasn't permitted to set
+foot inside the lighthouse, but in goes Mrs. Deline without a single
+question asked!"
+
+Her curiosity aroused, the girl decided to wait and watch. Twenty minutes
+elapsed. During that time Mrs. Deline did not reappear. Penny grew tired
+of her vigil.
+
+"Mrs. Deline evidently intends to stay there a long while," she thought
+as she drove on. "For all I know, she and the lighthouse keeper may be
+old friends. They did greet each other as if they were acquainted."
+
+At the airport Penny parked on the crowded lot. She dropped into the
+lunch room for a sandwich and then wandered out on the cement runway. The
+noon passenger plane presently was announced through the loudspeaker
+system. A moment later Penny glimpsed the big silver twin-motor transport
+gliding down over the tree tops. As it taxied up to unload passengers,
+she held her breath. Knowing that there had been several last-minute
+cancellation of tickets, she was afraid that Louise might not be aboard.
+
+But as the door of the big transport swung back, her chum was the second
+passenger to alight. Fresh and trim in a yellow wool suit, she flung
+herself into Penny's arms.
+
+"Have a nice trip, Lou?"
+
+"Oh, heavenly! Only it didn't last long enough. We were here almost
+before I knew we'd started. I nearly lost my ticket to an Army Major
+too!"
+
+"I was afraid you might not get here," Penny laughed, picking up Louise's
+light over-night case. "What happened to the Major?"
+
+"Oh, at the last minute he changed his mind, so the company decided I
+could have my ticket back. And here I am! How's camping?"
+
+"Not much fun so far," Penny confessed truthfully. "But I can feel things
+starting to pick up."
+
+"We'll have a wonderful time together."
+
+"You just bet we will!" Penny declared with emphasis. "Had anything to
+eat?"
+
+"Oh, yes, lunch was served on the plane."
+
+"Then we may as well start for camp. I have oodles to tell you, Lou."
+
+Midway to the parking lot, Louise paused, calling attention to a Flying
+Fortress that was coming in against the wind.
+
+"Let's watch it land," she pleaded. "Did you ever see such a beautiful
+ship?"
+
+The huge Fortress came in fast for a perfect landing. Crew members began
+to tumble out through the door. One of the young men in captain's uniform
+evidently was a passenger for he carried a suitcase.
+
+"Lou!" Penny grasped her chum's arm. "That flier looks like Jerry
+Livingston!"
+
+"Oh, it couldn't be!"
+
+"All the same, I think it is!"
+
+Penny was so excited that she barely could control her voice. Jerry
+Livingston was one of her very best friends, a former reporter on the
+_Riverview Star_. In the days before he had joined the Army Air Force,
+she and Jerry had shared many an exciting adventure. However, since he
+had gone away there had been only a few letters and those brief
+communications had contained no real news.
+
+"It _is_ Jerry!" Penny cried an instant later. "Oh, Lou, this must have
+been the surprise that Dad knew about! How could he keep it from me?"
+
+Breaking away from her chum, Penny darted across the runway. As she
+called Jerry's name, the young man turned toward her. His handsome,
+wind-tanned face became a brilliant smile. A dozen long strides carried
+him to her side.
+
+"Penny!" he cried. He didn't hesitate. He just swept her into his arms
+and kissed her.
+
+"Sorry, Penny," Jerry apologized, his eyes twinkling. "Guess I shouldn't
+have done that. But when you've not seen your one and only girl for going
+on a year--"
+
+"Your which?" Penny stammered, too confused to blush.
+
+"You are my one and only, you know," Jerry grinned. "Always were for that
+matter. Even in the days when we tracked down news stories together."
+
+Louise came hurrying up. Jerry turned to greet her and the conversation
+became less personal. But from the way Louise smiled, Penny knew she had
+seen the kiss and would demand lengthy explanations later on.
+
+"Jerry!" she cried, noticing the decorations on his trim uniform.
+"They've given you the Distinguished Flying Cross! And the Purple Heart!
+You didn't write a word about that."
+
+"Nothing to write."
+
+Indignantly, the girls pried the story from Jerry. He had piloted a
+Flying Fortress in a highly successful raid over the Romanian oil fields.
+To reach its target, the Fortress had flown through flaming refineries,
+so low to the ground that fire actually had leaped up through the bomb
+bay of the plane. Swarms of enemy fighter ships had been fought off.
+Jerry's plane was one of the few to get back to its base safely.
+
+"I was luckier than some of the other fellows," Jerry said modestly.
+"That was all. Now they've sent me home to rest up for a while."
+
+"Oh, that's marvelous!" Penny said, guiding him toward the waiting car.
+"You can spend all of your spare time with us!"
+
+Jerry grinned down at her. "I'd like nothing better. But I'm not exactly
+on furlough."
+
+"I thought you just said--"
+
+"I'm doing a special mission here at Sunset Beach for the Army."
+
+"Anything you dare tell about?"
+
+Jerry helped the girls into the car, stowed the suitcases away, and then
+slid in beside Penny.
+
+"I can't tell you very much," he replied quietly. "But I can give you a
+general idea of why I'm here. There's a certain outlaw radio station that
+has been causing the government considerable annoyance. I've been sent
+here to try to trace its location."
+
+"And that's why Dad's here too!" Penny cried. "So you two schemers
+intended to join forces all along! A pity no one could let me know!"
+
+"I didn't want your father to tell you, because until the last minute I
+wasn't sure I was coming," Jerry explained. "The radio station assignment
+is only part of the reason why I'm here."
+
+"What's the other?" Penny asked as she started the car.
+
+"I'm on the lookout for an escaped German flier. The fellow escaped from
+a Canadian prison camp and was traced to this locality."
+
+"And you're supposed to be taking a rest from flying!"
+
+"This assignment will be a vacation."
+
+"I'd call it anything but one," Penny said indignantly. Her face suddenly
+became grave. "Jerry!"
+
+"Yes?"
+
+"What does that escaped prisoner look like?"
+
+"Oh, I can't describe him. I have a photograph in my brief case. Why do
+you ask?"
+
+"Maybe I've seen him."
+
+"Where?" Jerry could not hide a smile.
+
+"Why at our camp in the woods!" Excitedly Penny told of the bearded
+stranger who had robbed the Parker stores of food and clothing. Her
+description of the man was so vague that Jerry could make little of it.
+
+"I'm afraid your thief isn't the man we're after," he said kindly. "After
+I get to a hotel and open my luggage, I'll show you his picture."
+
+"And will you let me help you trail him?"
+
+"Oh, sure," Jerry answered, only half meaning it. "By the way, drive me
+to the Crystal Inn. I have a reservation there."
+
+Penny's face fell.
+
+"Anything wrong with the place?" Jerry inquired, observing her change of
+expression.
+
+Penny shook her head. "The place is all right. It's the people who stay
+there. Jerry--"
+
+"Yes?"
+
+"Are you susceptible to brunettes?"
+
+"Never noticed it."
+
+"You'll likely meet a Mrs. Deline at the hotel," Penny warned. "Don't
+have a thing to do with her."
+
+"Why should I?" Jerry was amused.
+
+"She's already made a jelly fish of Dad," Penny went on. "Jerry, stop
+grinning! This is serious."
+
+"Sorry, I didn't know I was smiling."
+
+"I need your help, Jerry. The truth is, I'm terribly worried about Dad."
+
+"If I know your father, there's no need to worry about him."
+
+"But you don't understand this Mrs. Deline," Penny said desperately.
+"She's a very clever, scheming woman. Jerry, will you promise to help me
+try to save Dad from her clutches?"
+
+Jerry managed to keep his face straight. "I'll do my best," he promised.
+
+Penny drew a deep sigh. "Oh, I'm so glad you're here," she murmured
+gratefully. "With you fighting on my side, the war's as good as won!"
+
+
+
+
+ CHAPTER
+ 10
+ _HELP FROM MR. EMORY_
+
+
+With Jerry at Sunset Beach, the vacation already promised to take on a
+rosy hue. Penny was so thrilled to be with her friends again that she
+paid scant heed to her driving. Several times, enroute to the Crystal
+Inn, Louise had to warn her to steer more carefully.
+
+"Oh, Jerry, now that you're here the fun will start!" Penny declared
+happily. "You've no idea how dull things have been without you."
+
+"And that goes double," Jerry said with emphasis. "How's your father?"
+
+"Oh, fine!" Penny laughed. "Camping has made him cross though. By the
+way, did he know you were coming?"
+
+"Yes, I sent him a wire."
+
+"I thought so! Dad's been keeping it from me. Why all the secrecy, I
+wonder?"
+
+"Well, my trip here isn't exactly a pleasure jaunt. And if I have luck,
+I'll be gone again in a few days."
+
+"I certainly hope you have no luck then," Penny said with a laugh.
+
+The car drew up at the Crystal Inn and Jerry unloaded his suitcase. He
+was taller, Penny thought, or at least more filled out. The trim uniform
+set off his broad shoulders. As he bent to pick up his luggage, a group
+of women on the hotel veranda turned to stare at him.
+
+"I'll check in and clean up a bit," Jerry said. "Then where can I meet
+you girls?"
+
+"Oh, we'll be somewhere on the beach," Penny replied carelessly. "Do
+hurry, Jerry. We have a million things to talk over."
+
+The girls parked the car not far from the hotel. As they walked along,
+scuffing their shoes in the loose sand, they saw Mrs. Deline coming
+toward them from the direction of Crag Point.
+
+"She's evidently been at the lighthouse all this time!" Penny commented
+in an undertone. "Now how did she get in there for a visit when I
+couldn't?"
+
+Mrs. Deline saw that she would meet the girls. Frowning, she glanced
+quickly toward the boardwalk as if seeking an avenue of escape. However,
+she could not avoid meeting them without appearing to do so deliberately.
+
+"How do you do," she greeted Penny coldly.
+
+Penny paused to introduce Louise. Mrs. Deline acknowledged the girl with
+an indifferent nod. Somewhat confused, Louise nervously twisted a silver
+ring she wore. It slipped from her finger and fell into the loose sand.
+
+"Oh, how awkward of me!" she exclaimed, and stooped to retrieve it.
+
+The ring buried itself deeper in the sand.
+
+"You'll lose it entirely if you're not careful!" Penny warned. "Here, let
+me help you."
+
+Getting down on their knees, the girls sifted the sand with their hands.
+Mrs. Deline seemed amused by their difficulties and did not offer to
+help.
+
+"Well, I must be getting on to the hotel," she said casually. "I took a
+long walk this afternoon and I'm tired."
+
+"To the lighthouse?" Penny commented, before she stopped to think.
+
+Mrs. Deline glanced at her sharply. "No, not to the lighthouse," she
+replied in a tone meant to put the girl in her place. "I shouldn't think
+of walking that far."
+
+"But I thought I saw you there."
+
+"You saw me?" Mrs. Deline laughed. "Well, my dear, you certainly were
+mistaken. I walked to the 12th Street bridge. No farther."
+
+Penny started to reply, then thought better of it. There was no point in
+arguing with Mrs. Deline. However, she was certain she had seen the widow
+at the lighthouse. Why the woman should deny it she could not imagine.
+
+After Mrs. Deline had gone, Penny and Louise searched in vain for the
+missing ring. They knew it could not be many inches away, yet it kept
+eluding them.
+
+"Oh, I can't afford to lose the ring!" Louise wailed.
+
+"How valuable is it?"
+
+"It's not worth much from a money standpoint. I drew it as a prize in a
+piece of wedding cake and I've always kept it as a good luck piece."
+
+"We'll find it," Penny said confidently. "That is, if the tide doesn't
+catch us first."
+
+Just as she spoke, a wave came rippling up the beach. It broke only a few
+feet away, showering the girls with spray and wetting their shoes.
+
+"If the tide flows over this spot, I never will find the ring," Louise
+cried in vexation. "Such wretched luck!"
+
+"Having trouble?" inquired a deep masculine voice.
+
+Penny and Louise raised their heads. Unnoticed by them, a stranger had
+approached. The man wore a wet bathing suit plastered with sand. He had
+on glasses and a moment elapsed before Penny recognized him as the same
+fisherman who had warned her about the tide at Crag Point.
+
+"I'm George Emory," he introduced himself. "Have you lost something?"
+
+"My ring," Louise explained.
+
+The man helped the girls search for the missing trinket. By now waves
+were creeping higher and higher on the beach. A particularly big one sent
+Penny and Louise scurrying for safety.
+
+"It's no use looking any longer for the ring," Louise gave up. "Perhaps I
+can find it after the tide turns."
+
+"By then it will be washed away," replied Mr. Emory. "Ah! What's this?"
+
+He stooped to pick a shiny object from the sand.
+
+"It's my ring!" Louise cried in delight. "Oh, thank you for finding it!"
+
+The three retreated to higher ground. As Penny and Louise were about to
+start for the hotel, Mr. Emory suggested that they might like to share a
+picnic lunch with him. Neither of the girls was hungry, but to offend the
+man after he had found Louise's ring was unthinkable. Accordingly, they
+accompanied him to one of the gaily painted wooden umbrellas along the
+beach. Beneath its shade Mr. Emory spread a paper tablecloth and produced
+ample supplies of sandwiches, fruit and lemonade.
+
+"Were you expecting to eat all this food yourself?" Penny asked in
+amazement.
+
+"No, I was hoping to find a companion who would share it," replied Mr.
+Emory. "The truth is, I'm a pretty lonely old fellow."
+
+Penny and Louise stole a quick look at the stranger. By no stretch of the
+imagination could they call him old. Judging from appearances, he was not
+yet forty years old.
+
+"My wife died a few years ago," Mr. Emory explained sadly. "Since then
+I've been like a ship without a rudder. I have plenty of money, but I
+don't get much enjoyment out of life. I go wherever it suits my fancy,
+stay until I weary of it, then move on."
+
+"Oh, I see," Penny murmured with a show of sympathy.
+
+She felt ashamed of herself that the story did not move her more deeply.
+Mr. Emory evidently was a lonely fellow, deserving of companionship. Yet
+for some reason, he failed to interest her.
+
+"Have you been at Sunset Beach long?" she inquired politely.
+
+"Oh, about a month. I know every nook and cranny along the shore."
+
+"You do?" Penny asked, and her interest revived. "Are there many caves
+near Sunset Beach?"
+
+"Plenty of them, though none very close. There are several near the
+lighthouse, back among the rocks. Crystal Cave probably is the most
+interesting. Then there are half a dozen scattered on up the shore.
+Interested in caves?"
+
+"Oh, in a general way," Penny replied carelessly.
+
+"Penny is interested in anything that suggests mystery," Louise
+volunteered with a grin.
+
+"Mystery?"
+
+"Lou's joking," Penny said quickly. She gave her chum a hard look which
+was not lost upon Mr. Emory.
+
+"Why, Penny!" Louise refused to be silenced. "Only a few minutes ago you
+were telling me about a radio broadcast said to come from a cave!"
+
+"That was just my idea," Penny said, confused. She jumped hastily to her
+feet. "We really should be going, Lou."
+
+"Oh, don't hurry away." Mr. Emory offered Louise another sandwich.
+"Speaking of mysterious radio stations, I've heard of one that is said to
+be located in a cave somewhere along these shores. Fact is, I've searched
+for it."
+
+"You have?" Penny asked, sinking back into the sand. "Any luck?"
+
+"None. But I did manage to kill quite a few afternoons. I take it that
+your father came to Sunset Beach to help the authorities search for the
+station. Right?"
+
+"Why, whatever made you think that?" Penny asked, instantly on guard. "Do
+you know my father?"
+
+"I regret I haven't the honor. I chanced to overhear a conversation at
+the hotel."
+
+"Oh," Penny murmured. She was certain that the information could have
+leaked out in only one way. Her father had told Mrs. Deline, who in turn
+had spread the news about the hotel.
+
+"I trust I'm not inquiring into secrets," Mr. Emory went on cheerfully.
+"Fact of the matter is, I might be able to help your father."
+
+"I'm sure Dad will want to talk with you."
+
+"I'll look forward to meeting your father. Think you can arrange it?"
+
+"Why, I suppose so," Penny said, though with no great enthusiasm. Again
+she experienced a queer, uneasy feeling. She did not entirely trust Mr.
+Emory.
+
+The man smiled and seemed to relax. As the girls arose to leave he tried
+once more to detain them.
+
+"See that old fellow down the beach?" he inquired, pointing to an aged
+man who was picking up objects from the sand with a sharp-pointed stick.
+
+"Yes, what about him?" Penny asked, turning to stare. "Just an ordinary
+beachcomber, isn't he?"
+
+"I'd not call Old Jake Skagway ordinary," Mr. Emory corrected. "If you're
+really interested in solving the radio station mystery, I'd advise you to
+keep watch of that rascal."
+
+"But why him?" Penny asked.
+
+"I can't explain," Mr. Emory said with finality. "It's just a tip. Take
+it or leave it."
+
+Yawning, he stretched himself full length on the sand and turned his back
+to the girls.
+
+
+
+
+ CHAPTER
+ 11
+ _A MAN OF MYSTERY_
+
+
+The following day when Penny told her father of Mr. Emory's desire to
+meet him, Mr. Parker showed little interest.
+
+"I've no time to waste getting acquainted with strangers," he said. "Why
+is the man so eager to know me?"
+
+"He thinks he may be able to help you locate that hidden radio station."
+
+Mr. Parker's annoyance visibly increased. "Penny," he said severely,
+"you've evidently been talking out of turn."
+
+"I didn't mean to let him know why you're at Sunset Beach, Dad. It sort
+of slipped out."
+
+Louise, who was washing the breakfast dishes, spoke quickly.
+
+"It was my fault," she insisted. "Penny tried to stop me, but I gave the
+information before I thought."
+
+"Well, it doesn't matter," Mr. Parker assured her kindly. "I came here
+mostly for a vacation. If I should be lucky enough to dig up a few facts
+about the radio station, well and good. If not, no harm will have been
+done."
+
+"You sent for Jerry to help you?" Penny inquired curiously.
+
+Mr. Parker shook his head. "No, I knew he was coming, but I didn't send
+for him. If I had, I'm afraid the Army wouldn't have been obliging enough
+to have filled my order."
+
+Penny helped Louise put away the camp dishes and pick up loose papers. It
+was only eight-thirty but already most of the work had been done. With
+Louise to help, camping no longer was a burden. Even Mr. Parker seemed to
+have moments of enjoying the outdoor life.
+
+"Anyone riding to Sunset Beach with me?" he inquired cheerfully. "I have
+a date with Jerry this morning."
+
+Penny and Louise both wanted to go. They washed at the brook, changed
+into becoming "town" dresses, and soon were ready.
+
+At the Crystal Inn, Jerry was not to be found. A clerk explained that the
+young man had left the hotel a half hour earlier but was expected to
+return soon.
+
+"He probably went somewhere for breakfast or a walk," Mr. Parker
+remarked, sinking into a comfortable chair. "I'll wait for him."
+
+Penny and Louise loitered in the lobby. Presently Mrs. Deline came from
+the dining room and Mr. Parker politely arose to greet her. The widow
+took a chair beside him and they began to chat in an animated way.
+
+"Let's get away from here!" Penny muttered to Louise. "I don't like the
+scenery."
+
+The girls went outside into the warm sunshine. Because the Parker
+automobile was at the curb they climbed into it and sat watching the sea.
+
+"Why do you dislike Mrs. Deline so intensely?" Louise presently asked her
+chum.
+
+"Because she's aiming to be my stepmother, that's why!"
+
+"Oh, Penny!" Louise laughed outright. "I'm sure you have a mistaken idea
+about the entire situation. Your father isn't serious in liking her."
+
+"Then he's certainly developed remarkable talents for acting," Penny
+retorted with a sniff. "I wish we'd never come to Sunset Beach."
+
+"You'd be willing to forego the mystery?"
+
+"Who cares about a radio station?" Penny asked crossly. "Dad won't tell
+me anything about the case, and probably Jerry won't either. It seems to
+be one of those affairs for the experts only."
+
+"If I know you, Penny, you'll manage to get in on the affair," Louise
+said, her eyes twinkling.
+
+Penny turned on the ignition and started the car. "I'm just not
+interested," she announced flatly. "Mrs. Deline has taken all the fun out
+of me. Want to go for a ride?"
+
+"Where?"
+
+"Oh, just up the beach."
+
+"Isn't it dangerous to drive on the sand?"
+
+"Everyone does it at low tide. The sand is hard and firm along this
+stretch of beach."
+
+Louise offered no further objection, so Penny drove slowly away from the
+hotel. The car rode on silken tires, making only a soft swishing sound as
+it rolled smoothly over the sand.
+
+"Oh, this is fun!" Louise cried in delight.
+
+"We might drive to the lighthouse," Penny proposed, steering to avoid two
+bathers who crossed in front of the car.
+
+Following the curve of the beach, the girls kept on until the sand became
+so soft that they were afraid to drive farther. The lighthouse was close
+by. Penny, curious to learn what sort of reception the keeper would
+accord her on the second visit, proposed to Louise that they call there.
+
+"If he let Mrs. Deline visit the tower why can't we?" she argued. "Come
+along, let's try to get in!"
+
+Abandoning the car on the beach, they waded through the dunes, climbed a
+fence, and ultimately reached the base of the tower. No one seemed to be
+in evidence. Penny started boldly up the iron steps. However, before she
+had gone very far, the keeper, Jim McCoy, came out on the platform.
+
+"Didn't I tell you no visitors are allowed here?" he called down angrily.
+
+"I saw a lady come here yesterday!" Penny returned.
+
+"You must have dreamed it," retorted the lighthouse keeper. "No visitors
+allowed. Don't make me tell you again!"
+
+Penny retreated, decidedly crushed.
+
+"You asked for it, kitten," Louise teased as they walked toward the car.
+"I don't blame the keeper for not wanting visitors."
+
+"Mrs. Deline was there," Penny insisted stubbornly. "Why should he deny
+it?"
+
+Half way to the car, the girls paused to pick up a few large shells lying
+in the deep sand. The task became an absorbing one. Before they realized
+it, the sun was high overhead and their faces were being burned by the
+direct rays.
+
+"Let's go," Louise urged. "The tide turned a long while ago. We should be
+returning to the hotel."
+
+"Okay," Penny agreed. She stooped to pick up another shell. As she
+straightened, she observed an old man in ragged clothing coming down the
+beach.
+
+"Lou," she said in a low tone, "there's that same man Mr. Emory was
+telling us about!"
+
+"The beachcomber?" Louise turned to stare.
+
+"Yes, and he's coming this way. Perhaps it might be worth while to watch
+him."
+
+"He's not seen us yet."
+
+Penny glanced about for a hiding place. The only one that offered was a
+huge sand dune. Pulling Louise along with her, she crouched down out of
+sight.
+
+In a moment the old beachcomber came along. He was whistling and seemed
+to have not a care in the world. His face, viewed at close range, was
+weather-beaten, his hair uncombed, and his clothing had not been washed
+in many a day.
+
+"What's so mysterious about him?" Louise whispered. "Why did Mr. Emory
+say he'd bear watching?"
+
+"Maybe he's not really a beachcomber," Penny returned, low. "He may be an
+Enemy Agent in disguise."
+
+"You have Enemy Agents on the brain!" Louise chuckled. "Likewise,
+man-snatching widows."
+
+The beachcomber passed within a few feet of the girls. He crossed the
+courtyard of the lighthouse and was seen to take a trail which led amid
+the rocks.
+
+"Lou, perhaps he's going to one of the caves!" Penny cried. "You know Mr.
+Emory said this locality is honeycombed with them."
+
+"Let him go," Louise answered indifferently. "It's lunch time and I'm
+hungry."
+
+"Your appetite will have to wait. I'm going to follow that man!"
+
+"Oh, Penny."
+
+"But this may be important."
+
+"And it may be just another of your so-called bright ideas," Louise
+retorted. "Well, lead on, and let's get it over with."
+
+The beachcomber already had disappeared amid the mass of piled-up rock
+farther back from shore. Penny had marked the locality well with her eye.
+She was able to lead Louise to the place where he had vanished.
+
+"See, there's a well-worn trail," she indicated triumphantly. "He must
+have taken it."
+
+They followed the path, and a moment later caught a fleeting glimpse of
+the beachcomber. At times the trail was so narrow that the girls barely
+could squeeze between the rocks. Wind whistled around the cliffs,
+whipping hair and blowing skirts.
+
+Unexpectedly, Penny, who was in the lead, came to the low entranceway of
+a cave.
+
+"He must have gone in there!" she declared excitedly. "Listen!"
+
+From deep within the cave the girls could hear a strange sound.
+
+"Rushing water!" Louise said in awe. "The Cave must have a waterfall or
+an underground river."
+
+"We'll soon know." Penny started into the cave only to have Louise clutch
+at her hand.
+
+"Don't be silly, Penny. We have no flashlight."
+
+"But we can't let that beachcomber get away. We want to learn what he
+does."
+
+"I can bear up without knowing."
+
+"Well, I can't," Penny announced with equal firmness.
+
+"But it may be dangerous. Let's go back to the hotel and get Jerry or
+your father."
+
+Penny hesitated, then shook her head. "You stay here if you like, Lou,"
+she replied. "I'm going inside."
+
+Before her chum could detain her, she stooped low and crawled into the
+narrow, dark tunnel.
+
+
+
+
+ CHAPTER
+ 12
+ _CAUGHT BY THE TIDE_
+
+
+Unwilling to be left behind, Louise followed her chum into the dark
+cavern. Once she and Penny were well beyond the yawning mouth of the
+cave, they could not see a foot ahead of them. Guided by the sound of
+rushing water, they groped their way along a damp wall.
+
+"This is awful!" Louise whispered nervously. "Let's turn back."
+
+Penny might have yielded to her chum's coaxing but at that moment the
+tunnel broadened out and became lighter. Directly ahead a series of steps
+led down to a lower room of the cave.
+
+"This place must be safe enough or steps wouldn't have been built here,"
+she whispered. "Don't be nervous, Lou. We may discover something
+important."
+
+Louise muttered that they were more likely to break their necks. However,
+she cautiously followed Penny down the rock-hewn steps. Half way down,
+they both paused. From below came a weird sound.
+
+"What was that?" Louise whispered.
+
+"It sounded for all the world like the note of a pipe organ!" Penny
+observed. "There it is again--a different tone this time."
+
+Noiselessly the girls moved on down the steps. Ahead of them they now
+could see a moving light which undoubtedly was a flash lantern carried by
+the beachcomber. Drawing closer, they saw the man himself. In the great
+cavern his shadow appeared grotesque and huge.
+
+"What is he doing?" Louise whispered in awe.
+
+The man was unaware that he had been followed. He stood in the center of
+the great chamber, gazing with wrapt expression at the stalagmites which
+rose in strange formations from the cave floor. The girls could hear him
+muttering to himself. At the risk of being seen they moved closer.
+
+"Music! Music!" the old man mumbled. "Talk about your pipe organs! They
+ain't in it with _this_!"
+
+He held a long stick in his hand and with it began to explore the row of
+stalagmites, striking them one by one, at first with a slow tempo and
+then faster and faster. The weird sounds echoed and reached through the
+galleries of the cavern.
+
+"Pretty!" the old man prattled. "It's the music o' Heaven. There ain't no
+music to equal it."
+
+Again the beachcomber struck the stalagmites, listening raptly while the
+sounds died slowly away.
+
+"Come on, Penny," Louise urged, tugging at her hand. "Let's get out of
+here. That old goof has lost his buttons."
+
+Decidedly crestfallen, Penny permitted herself to be pulled along the
+passage and up the steps. As the girls groped their way to the cave's
+mouth, they still could hear the weird echoing tones.
+
+"That was a good joke on you!" Louise teased. "You thought you were going
+to find a hidden radio station!"
+
+"Well, we did find a cave," Penny said defensively.
+
+"We didn't exactly discover it," Louise amended. "This must be Crystal
+Cave. Seemingly that old beachcomber regards it as his own personal
+property."
+
+"Mr. Emory certainly gave us a wrong steer. A mysterious character, my
+eye!"
+
+"You'll admit that the old fellow is interesting," Louise laughed.
+"However, I doubt he'll warrant much attention from the FBI."
+
+"All right, laugh," Penny retorted grimly. "You think my detective
+efforts are a joke anyway."
+
+"No, I don't, Penny. But I will say I doubt you'll have success tracing a
+hidden radio station. After all, it's a problem that has the State
+authorities baffled. Not to mention Uncle Sam's Army."
+
+The girls stepped from the cave out into the brilliant sunshine. Gazing
+toward the sea, they were amazed to see how high the tide had risen.
+Giant waves were washing very close to the Parker automobile left on the
+beach.
+
+"Ye fishes!" Penny exclaimed in horror. "I forgot all about the car!"
+
+"And the tide's coming in fast!"
+
+"The Point will be cut off in a few more minutes!" Penny added, recalling
+Mr. Emory's warning. "We'll have to travel, and travel fast!"
+
+Scrambling down from the rocks, the girls plunged through the dunes to
+the beach. A wind was blowing and the sea had an angry look.
+
+"If just one wave strikes the car, the wheels will sink in the sand, and
+then we'll be in it!" Penny cried.
+
+With increasing alarm she noted that sand was damp within a foot of the
+rear wheels. And as she jerked open the car door, a greedy wave nipped
+again at the rubber.
+
+"We'll soon be out of here," Louise said encouragingly.
+
+Penny stepped on the starter and to her relief the motor caught
+instantly. In great haste she turned the car around, circling away from
+the inrushing sea.
+
+"Careful!" Louise warned. "The sand is dreadfully soft this far up
+shore."
+
+Too late Penny realized the same thing. She could feel the car starting
+to bog down. The motor began to labor. Then the car stalled completely.
+
+"We're stuck!" she gasped.
+
+Both girls sprang out to look at the wheels. Their spirits sank. On one
+side, front and rear tires were bogged deep in sand.
+
+"Start the engine again!" Louise urged desperately. "I'll try to push."
+
+Penny obeyed, but her chum's puny strength made not the slightest
+impression upon the car. It could not be moved a foot. The spinning
+wheels only drove deeper and deeper into the sand.
+
+"What shall we do?" Louise asked helplessly. She turned to stare at the
+incoming sea. Each wave was breaking a little closer to the car.
+
+"This place will be under in another twenty minutes," Penny calculated.
+"Even if the car isn't washed away, the salt water will ruin it. How did
+we ever get into such a mess?"
+
+"Just by being careless. If only we weren't so far from the hotel!"
+
+"I'll run to the lighthouse," Penny decided desperately. "Maybe the
+keeper will help us."
+
+Both girls were badly frightened, not for their own safety, but because
+they feared that the car would be damaged beyond repair. Once the waves
+began to strike it, it would sink deeper and deeper into the sand. Salt
+water would corrode all of the bright chromium.
+
+"We've no time to waste!" Penny cried, darting away.
+
+The girls plunged through the sand drifts to the lighthouse. Evidently
+the keeper already had observed their plight, for he was standing on the
+upper platform peering down into the courtyard.
+
+"Our car is stuck in the sand!" Penny shouted. "Can you help us get it
+out?"
+
+"No, I can't," the keeper answered gruffly. "You should have watched the
+tide."
+
+"There's no one else to help us," Penny pleaded. "Just a little push--"
+
+"I'm forbidden to leave my post."
+
+"Then will you telephone to the Inn? Or to a garage?"
+
+"I could 'phone but it wouldn't do any good," the keeper said
+reluctantly. "Your car will be under water before a tow-car could get
+here."
+
+Exasperated by the man's unwillingness to help, Louise and Penny ran back
+to the car. Already waves were lapping against the rear wheels. The
+situation seemed hopeless.
+
+"Shall I try to push again?" Louise asked.
+
+"It wouldn't do any good. We're not strong enough." In desperation,
+Penny's gaze wandered down the deserted shore. Suddenly she saw a lone
+fisherman who was wading through the surf. She recognized him as George
+Emory.
+
+"He'll help us!" she cried confidently.
+
+The girls shouted Mr. Emory's name. Apparently he heard, for he turned
+his head quickly. Their plight, they thought, must be instantly evident,
+but Mr. Emory did not seem to comprehend. He waved his hand as if in
+friendly greeting, and then, reeling in his fish line, turned and walked
+away from them.
+
+
+
+
+ CHAPTER
+ 13
+ _A HIDDEN PACKAGE_
+
+
+"Why, Mr. Emory doesn't understand!" Penny cried, aghast. "Can't he see
+that we're stuck here with the tide rolling in?"
+
+The girls shouted again and again. If the man heard, he gave no sign.
+
+"I don't believe he wanted to help us!" Penny declared furiously.
+"Probably he's afraid he'll over-strain himself pushing!"
+
+Unwilling to give up without a last try, she sprang into the car and once
+more started the engine. It roared and labored but could not pull the
+vehicle. Sick with despair, Penny allowed the motor to idle. She slumped
+behind the steering wheel, only to straighten suddenly as she thought she
+heard her name called.
+
+Louise too heard the cry for she turned quickly toward the main road some
+yards back from the beach. A young man in uniform was running across the
+dunes toward the girls.
+
+"It's Jerry!" Penny cried jubilantly. "He'll help us!"
+
+"He will if he can," Louise corrected. "The tide's coming in so fast now.
+I doubt anyone can get us out of here now."
+
+Jerry did not waste time asking questions. Taking in the situation at a
+glance, he instructed Penny to remain at the wheel. With the motor
+racing, he and Louise pushed with all their strength. At first the rear
+wheels kept spinning in the sand. A great wave slapped the rear end of
+the car, spraying Louise from head to foot.
+
+"It's no use!" she gasped. "We can't do it."
+
+"Yes, we can!" Jerry insisted. "Try once more, Louise."
+
+Again they pushed and this time the car actually moved a few feet before
+it bogged down. Encouraged, Jerry and Louise tried harder than before.
+The wheels suddenly struck firm sand, dug in, and the car began to creep
+forward. Penny kept it moving until she was sure the footing beneath the
+tires was solid. Then she pulled up so that Jerry and Louise might leap
+aboard.
+
+"Drive as fast as you can for the hotel!" Jerry instructed crisply.
+"We'll be lucky to make it."
+
+Where an hour before the roadway along the beach had been wide and ample,
+there now was only a fringe of white sand. To avoid the incoming waves,
+Penny had to drive dangerously close to the dunes. And midway to the
+hotel, they came to a flooded stretch of beach.
+
+"We'll have to risk it," Jerry advised as Penny hesitated to drive on.
+
+The water was not deep but the sand was wet and treacherous. Choosing a
+moment between breakers, Penny braved it, and to her intense relief the
+car rolled through without sinking down.
+
+"It's clear sailing now," Jerry said as a wider strip of beach opened
+before them. "We're well beyond the Point."
+
+Mr. Emory was walking along the shore and as the car went past, he waved
+his hand in a friendly way. Penny did not bother to return the salute,
+pretending she did not see him.
+
+"I'm sure he knew we were in trouble and didn't want to help," she told
+Jerry. "The more I see of that man the less I like him."
+
+"Who is he anyhow?"
+
+"Just a vacationer. He got Lou and me all excited yesterday with his talk
+about that hidden radio station."
+
+"How do you mean?" Jerry asked with interest.
+
+Penny repeated the conversation, and mentioned how Mr. Emory had
+suggested that the old beachcomber was a mysterious character that would
+bear watching.
+
+"Not old Jake Skagway?" Jerry asked, amused.
+
+"I believe that was his name."
+
+"Jake's the only beachcomber I know hereabouts. He makes his living
+picking up things on the beach and selling them. Folks say he buries some
+of his loot in the caves."
+
+"How do you know so much about him, Jerry?"
+
+"Oh, I used to run down to Sunset Beach real often years ago. I know this
+locality like a book. Guess that's why the Army sent me here to do a
+little scouting around."
+
+Penny waited expectantly, but Jerry offered no more information as to the
+reason for his visit to Sunset Beach.
+
+"Probably Lou and I were taken in by Jake Skagway," she admitted after a
+moment. "If we hadn't followed him into the cave, we certainly wouldn't
+have involved ourselves in such difficulties."
+
+Upon reaching the Crystal Inn a few minutes later, the girls searched for
+Mr. Parker. He was nowhere to be found. After waiting for a time, they
+left the car with Jerry and hiked to the forest camp. There the early
+afternoon was devoted to camp tasks. When Mr. Parker still did not come,
+Penny proposed that they return to Sunset Beach for a plunge in the surf.
+
+"Too cold," Louise shivered.
+
+"Well, let's go down to Sunset Beach anyhow," Penny urged. "I get
+restless just sitting here in camp."
+
+"You know you want to see Jerry again," Louise teased. "'Fess up."
+
+"All right, I do want to see him," Penny admitted unabashed. "Jerry's my
+very best friend. I've not been with him in months and I suppose in a few
+days he'll be shot off to goodness-knows-where."
+
+"He's not told you very much about why he came here."
+
+"No," Penny said briefly. The subject was a sore one with her. She felt
+that both her father and Jerry were keeping secrets.
+
+The tide was still high when the girls reached the beach, but the flow
+was outward. Sprawling in the warm sand, they watched the gulls.
+
+"Wonder what became of Jerry and Dad?" Penny speculated. "They're
+probably together somewhere."
+
+"Or with Mrs. Deline," Louise suggested wickedly.
+
+She was sorry that she had spoken for Penny's face immediately became as
+black as a thundercloud.
+
+"Sorry," Louise apologized. "I was only joking."
+
+Penny continued to scowl for at that moment she glimpsed Mrs. Deline
+walking rapidly down the beach. The widow came from the direction of the
+lighthouse and was alone. To avoid the incoming waves she waded ankle
+deep through the great sand ridges along the drift fence.
+
+"That's queer," Penny muttered, sitting up.
+
+"What is?"
+
+"Why, Mrs. Deline apparently has been at the lighthouse again. What's she
+doing now?"
+
+The widow had paused. Carefully she gazed up and down the deserted shore,
+but she did not see Penny and Louise who were hidden from view by a sand
+dune. However, by raising up slightly, they could see her plainly.
+
+Mrs. Deline carried a package of considerable size under her arm.
+Seemingly satisfied that no one was at hand to observe her actions, she
+moved swiftly to one of the sand dunes near the drift fence. As the girls
+watched in amazement, she dug a deep hole and buried the package. Her
+work completed, she carefully brushed sand over the spot and obliterated
+her own footprints one by one.
+
+"What was the idea of that?" Louise asked in bewilderment.
+
+"That's what I want to know!" Penny muttered. "We'll wait until she
+leaves and then find out the contents of that package!"
+
+But Mrs. Deline did not immediately go away. Instead she sat down in the
+sand close by. The girls could not see very well but they thought she was
+writing something on the skirt of her white suit.
+
+"Why is she doing that?" Louise asked in bewilderment.
+
+"I'll bet a cookie she's writing down the location of what she hid in the
+sand dune!" Penny speculated. "That's so she can find it again!"
+
+"But why write it on her skirt? And why should she hide anything here on
+the beach?"
+
+"Because she's a spy!" Penny declared triumphantly. "I've been suspicious
+of her from the first!"
+
+"Yes, you have, darling," agreed Louise. "But would a spy necessarily
+hide a package? If Mrs. Deline had information to communicate wouldn't
+she send it to her superiors? Besides, Sunset Beach isn't even an
+important manufacturing town."
+
+"That's true. But I've heard Dad say that the Coast Guards watch this
+place closely. Because of its isolation and jagged coastline it's
+considered a likely spot for surprise night landings by the Enemy."
+
+"Only this morning you thought old Jake Skagway was a rascal," Louise
+chuckled. "You don't catch me falling for your theories this time."
+
+"Then you have no interest in that hidden package?"
+
+"Of course I have! I merely don't agree that Mrs. Deline is a spy."
+
+"Quiet!" Penny warned. "Here she comes!"
+
+Mrs. Deline had arisen from the sand and came rapidly down the beach. She
+did not see the girls until she was very close to them. Involuntarily,
+she paused, and looked somewhat disconcerted. Recovering, she spoke
+coldly.
+
+"Hello," Penny responded, her gaze on the woman's white flannel skirt. It
+bore not a single tell-tale mark.
+
+Mrs. Deline went on down the beach.
+
+"You see," Louise whispered when the woman was beyond hearing, "she
+didn't write anything on her dress."
+
+"But we saw her do it!"
+
+"We only thought we did."
+
+"Maybe she wrote it in invisible ink."
+
+"Oh, Penny, you certainly have an imagination," Louise sighed.
+
+"I suppose I imagined about the package too?"
+
+"No, she really did bury something in the sand."
+
+"Then what are we waiting for?" Penny demanded, leaping to her feet.
+"Let's dig it up, and then maybe we'll have the answer to a few of our
+questions."
+
+
+
+
+ CHAPTER
+ 14
+ _VOICE FROM THE CAVE_
+
+
+From a distance Penny and Louise had marked well the spot where Mrs.
+Deline had buried the package. But as they approached the drift fence all
+of the dunes seemed strikingly similar in appearance. They could not
+agree as to the exact mound which contained the hidden package.
+
+"It was buried in this one, I think," Penny said, starting to dig. "Mrs.
+Deline certainly did a good job of covering her tracks."
+
+"You're wasting time working on that dune," Louise insisted. "I'll get
+busy over here and turn up the package in nothing flat."
+
+Selecting a mound of sand several feet from Penny, she began to dig with
+a will. The mysterious package proved elusive. Scarcely had the girls
+started work than a few raindrops splattered down.
+
+"Oh, it's going to storm!" Louise exclaimed, turning startled eyes toward
+the dark sea.
+
+The rain came down faster and faster. Faced with a choice of abandoning
+the search or being drenched, the girls decided to make a dash for the
+hotel.
+
+As they darted up the steps at the Crystal Inn, they were surprised to
+see Mrs. Deline sitting on the veranda. A spyglass lay in her lap.
+Whether she had been watching the sea or their own antics they had no way
+of knowing.
+
+"Have you seen my father, Mrs. Deline?" Penny asked, shaking the
+raindrops from her flying hair.
+
+"Indeed, I don't keep track of his whereabouts," Mrs. Deline replied
+coldly. "By the way, did you find what you were searching for in the
+sand?"
+
+The question caught Penny off guard. She stammered a few words which only
+caused the widow to smile in a knowing, amused way.
+
+"I don't mind telling you what I buried in the sand," she resumed. "It
+may save you a little trouble. The package contained nothing but fish
+bones."
+
+"Fish bones!"
+
+"Yes, I had just visited my friend, Jim McCoy, at the lighthouse. It's
+most difficult to bury anything there because of so many rocks. He asked
+me to dispose of the scraps for him."
+
+"Oh," Penny murmured, completely deflated.
+
+"I've been watching you girls through the spyglass," Mrs. Deline went on.
+"It really was amusing."
+
+"I can imagine," Penny agreed grimly. "Oh, well, I'm glad to provide a
+little amusement for this dead place."
+
+She and Louise retreated until they were screened from the widow by a
+potted palm.
+
+"I guess she scored on you that time, Penny," Louise commented. "So we
+wasted our strength digging for garbage!"
+
+"You needn't rub it in."
+
+"But it's all so silly. Why don't we try to like Mrs. Deline, Penny?"
+
+"I'll leave that job up to you. Furthermore, how do I know she was
+telling the truth? Maybe she just handed us that story so we wouldn't go
+on digging in the dunes!"
+
+"That's so!" Louise acknowledged. "Mrs. Deline isn't the type to be doing
+gracious little jobs for anyone."
+
+"If Jim McCoy asked her to bury a package of garbage, she would have
+disposed of it long before she did," Penny reasoned. "Instead, she walked
+quite a distance down shore. Then she seemed to select a particular dune,
+as if by pre-arrangement."
+
+"You think she may have hidden something there expecting another person
+to pick it up?"
+
+"That's my theory, Lou. Oh, I wish this rain would let up."
+
+Restlessly Penny walked to a window. The rain showed signs of slackening.
+And as she watched, a taxi drew up in front of the hotel. Jerry
+Livingston leaped out.
+
+"Wait for me!" he instructed the driver. "I'll be right back."
+
+Penny and Louise managed to block Jerry's path as he came hurrying into
+the hotel.
+
+"Hello, girls," he greeted them offhanded. "Want to go for a drive into
+the country?"
+
+"We certainly do," Penny accepted for both. "What's our destination?"
+
+"Tell you on the way," Jerry answered.
+
+He disappeared into an elevator, but was back in the lobby within a few
+minutes. Taking Penny and Louise each by an elbow, he escorted them to
+the waiting cab.
+
+"In a way, this is a secret trip," he said after he had given directions
+to the driver. "Ever see a radio monitoring truck?"
+
+"Never even heard of one," Penny replied. "What is it?"
+
+"Well, we have a truck equipped so that our instruments pick up the
+direction from which any short wave broadcast is sent. It's not generally
+known that the Army's at work here, so whatever you girls see you must
+keep under your sunbonnets."
+
+The taxi sped along the country road, following a route that was
+unfamiliar to the girls. By the time it drew up several miles from Sunset
+Beach the rain had ceased.
+
+"Tumble out," Jerry said, opening the cab door. "This is the end of the
+line."
+
+He went ahead, breaking a hole in the tall hedge at one side of the road.
+Eagerly the girls followed him through the gap. In a clearing just beyond
+a clump of saplings stood what appeared to be an ordinary covered Army
+truck.
+
+An enlisted man came toward Jerry and the girls, saluting smartly.
+
+"Are you picking up any signals?" Jerry asked him.
+
+"Nothing yet, sir. The weather hasn't been very favorable."
+
+"You've had your equipment set up here two days now?"
+
+"Right, sir."
+
+"It's not likely we'll get anything today or tonight," Jerry replied.
+"Oh, well, we'll have to have patience. Sooner or later the station will
+go on the air again, and then we'll learn its location."
+
+Louise and Penny were curious to learn more about the monitoring truck.
+Jerry took them inside, introduced them to the officers, and showed them
+the radio apparatus.
+
+"Our truck is equipped with rotating antennae," he explained. "Whenever
+the unknown station starts to broadcast we'll be able to swing our loops
+toward the signals. Then we chart the signals and where the lines
+intercept, the station is located."
+
+"As you explain it, Jerry, finding any radio station is a simple matter."
+
+"It is, providing the station doesn't move in the meantime.
+Unfortunately, Mr. Voice from the Cave is an elusive fellow."
+
+"You have no idea who the man may be?"
+
+"No, he's known to FBI agents only as B4 which is a code number."
+
+"What is the purpose behind the broadcasts?" Louise inquired. "Enemy
+propaganda?"
+
+"We know that the station is enemy owned and operated," Jerry replied.
+"So far that's about all we do know, for we've been unable to break the
+code. We suspect that persons connected with the station may be aiding
+German prisoners to escape from the country."
+
+"Prisoners originally held in Canada?" Penny inquired.
+
+"Yes, they've been aided by a ring of very clever spies."
+
+Penny was silent as she thought over the information. There were many
+questions she longed to ask.
+
+"Jerry--" she began, but just then there came an interruption.
+
+In the Army truck an officer had adjusted his earphones. His attitude as
+he listened was one of tense expectancy.
+
+"Picking up any signals?" Jerry demanded.
+
+The other man nodded. "Something's coming in! Yes, it's our friend, the
+Voice. In just a minute we should know exactly where the station is
+located."
+
+Jerry and the girls remained in the truck, eagerly awaiting a report from
+the efficient men who manned the radio direction finders.
+
+"Okay, we've got it charted!" came the terse announcement a moment later.
+
+"Where's the station located?" Jerry demanded eagerly. "Let's see the
+chart."
+
+It was thrust into his hand. Jerry stared at the intercepting lines and
+then at a map of the district.
+
+"Why, the station seems to be located along the shore!" he exclaimed.
+"Apparently in one of the caves--Crystal Cave I'd judge."
+
+"That's the cave where Louise and I were!" Penny exclaimed. "But we saw
+no shortwave radio apparatus. Only crazy old Skagway who was playing a
+tune on the stalagmites."
+
+"All the same, direction finders don't lie. The broadcast came from
+Crystal Cave! But that doesn't mean the station will be there fifteen
+minutes from now."
+
+"What's to be done?" Penny asked. "Can't the Voice be caught before he
+has a chance to move his portable outfit?"
+
+"A message already has been sent to Headquarters. Army men should be on
+their way to the cave now."
+
+"Jerry, we're not far from Crystal Cave ourselves!" Penny exclaimed, her
+eyes dancing with excitement. "Can't we go there too?"
+
+"We can and will!" Jerry laughed. "But if we expect to catch our friend,
+the Voice, there's no time to lose. Come along, girls, if you're
+traveling with me."
+
+
+
+
+ CHAPTER
+ 15
+ _AFTERGLOW_
+
+
+Penny sprawled on the grass beside the dying embers of the camp fire.
+Listlessly, and with very bad aim, she hurled acorns at a brown squirrel
+chattering overhead.
+
+"You've been in a bad mood ever since we got back from Crystal Cave,"
+Louise observed, coming out of the tent. "But why take it out on that
+poor creature?"
+
+Penny raised herself on an elbow. She scowled and did not reply.
+
+Louise moved over to the fire, seating herself on a log beside her chum.
+
+"Oh, brace up," she said, slipping an arm about Penny's shoulders. "In
+all my life I've never seen you act so discouraged."
+
+"I feel lower than the worms. Nothing's gone right since we came to
+Sunset Beach."
+
+"On the contrary, I can't see that anything has gone so very wrong."
+
+"Wasn't our trip to the Crystal Cave a bust?" Penny demanded.
+
+"Well, it wasn't a success."
+
+Louise smiled wryly at the recollection. With Jerry and the Army men, she
+and Penny had spent the afternoon searching various caves along the water
+front. Not a trace had been found of the mysterious radio station which
+so plagued local authorities. The search had been a long and exhausting
+one. In the end, though the others kept on, she and Penny had been
+compelled to give up.
+
+"My feet hurt yet from scrambling over the rocks," Penny declared. "I
+suppose Jerry and those Army officers will keep searching half the
+night."
+
+"And I'll warrant they never do find the station," Louise contributed.
+"This is one mystery I wish you had never stumbled into, Penny."
+
+"I'm beginning to feel the same way, Lou. This is supposed to be a
+vacation. I'd like to see Dad and Jerry once in awhile."
+
+"So that's what's bothering you!"
+
+"Well, you know Jerry will be here only a few days at most," Penny said
+defensively. "I've barely had a chance to say 'hello' to him. Dad's
+always down at the hotel too."
+
+"What you crave seems to be male companionship."
+
+Penny tossed a stick of wood on the fire, making the sparks fly. "I could
+do with a little," she admitted. "Life is too dull here."
+
+"Dull?" Louise gazed at her chum suspiciously.
+
+"It's no use being surrounded by mystery if one can't get into the thick
+of it. So far all the adventure has by-passed us."
+
+"We might stir up a little excitement by looking for that package Mrs.
+Deline buried in the sand."
+
+"Not today," Penny said with a sigh. "Too tired. Besides, I told Jerry
+about it and he wasn't much impressed."
+
+"So that's the reason for your gloom," Louise remarked wisely. "As a
+detective you don't rate."
+
+"Something like that. Jerry met Mrs. Deline at the hotel today and he
+thought her a very charming lady."
+
+"Oh!" Louise laughed. "No wonder you're all smashed to bits!"
+
+Penny got up from the grass and began preparations for supper. She peeled
+a pan of potatoes and opened a can of corn.
+
+"We need a bucket of water from the spring," she said suggestively. "Want
+to help me carry it?"
+
+"I will," Louise agreed without enthusiasm.
+
+The trail led up a steep path to a rocky ledge from which cool spring
+water gushed out of a steel pipe. Penny drank deeply and then hung her
+tin bucket over the outlet to fill.
+
+"It's starting to get dark," she observed, noticing how shadowy the woods
+had grown. "I hope Dad returns to camp soon."
+
+"Someone's coming now," Louise remarked as her keen ears detected the
+sound of footsteps on the trail below.
+
+"Probably one of the rangers."
+
+Penny unhooked the water bucket from the pipe, and the girls started down
+the trail, carrying it between them. Emerging from among the trees, they
+glimpsed a figure below them. A woman in a dark cloak who carried a
+picnic hamper, was walking rapidly up the winding trail.
+
+Penny stopped so suddenly that she spilled water on her sandals.
+
+"Lou, that's Mrs. Deline!" she whispered.
+
+"What of it, pet? She's evidently going on a picnic."
+
+"At this time of day? And alone?"
+
+"Well, that part of it does seem a bit odd."
+
+Penny pulled her chum into the bushes beside the path. Crouching low
+beside their water bucket, they allowed the woman to pass. Looking
+neither to the right nor left, she hastened on up the trail.
+
+"She seems to be in a big hurry," Penny commented, coming out of hiding.
+"Now where do you suppose she's going?"
+
+"Probably to the cabin. One of your ranger friends told me about a rustic
+place farther up the trail. It was built especially for the enjoyment of
+the public."
+
+"But why would Mrs. Deline go there alone?"
+
+"Maybe she intends to meet someone."
+
+"Lou, that's probably what she is going to do!" Penny exclaimed. "Let's
+follow her and find out."
+
+"What about supper?"
+
+"Who cares for food?" Penny demanded. "If Dad comes home he can rustle a
+little for himself. It's more important that we follow Mrs. Deline."
+
+"Okay," Louise agreed, "only I'm in no mood to walk very far. Remember,
+we've had one wild chase today."
+
+Leaving the water bucket behind the bushes, the girls set out in pursuit
+of Mrs. Deline. Not without admiration they acknowledged that the widow
+was a better trail climber than they. Though the hamper she carried
+evidently was heavy, she fairly skimmed up the rough trail. Penny and
+Louise fell farther and farther behind.
+
+"She's heading for the cabin all right," Penny puffed. "Of course she
+intends to meet someone. Otherwise, she'd have had her picnic on the
+beach or some place closer to the hotel."
+
+A clearing opened up through a gap in the trees. Mrs. Deline paused as
+she came within view of the rustic log cabin and gazed carefully about.
+The girls saw her look at her wrist watch.
+
+"She has an appointment with someone," Penny declared.
+
+Mrs. Deline walked to the door of the cabin and tested it to make certain
+that it was unlocked. She did not go inside. Instead, she set down the
+hamper and gazed slowly about the clearing. Louise and Penny, at the
+fringe of woods, saw her start as she looked directly toward them.
+
+"She's seen us!" Louise gasped.
+
+"We'll have to go out and meet her," Penny decided instantly. "Let's
+pretend we just happened to be coming this way. But we'll stick around
+and see who she's meeting."
+
+Mrs. Deline stiffened visibly as the girls sauntered out of the woods
+toward her.
+
+"Well, this is a surprise meeting you," she said in a tone none too
+friendly. "Is your camp located near here?"
+
+"Down the trail a short distance," Penny replied, thoroughly enjoying the
+widow's discomfiture. "Having a picnic?"
+
+"Why, yes. I love the outdoors and thought I'd take a hike this
+afternoon."
+
+"It's rather late for a picnic," Penny said pointedly.
+
+"It took me longer to get here than I expected."
+
+In an effort to discourage her young annoyers, Mrs. Deline pushed open
+the door of the cabin. Before she could pick up the hamper, Penny seized
+it.
+
+"Let me," she said quickly. "My how heavy! All this food for one person?"
+
+"Certainly," Mrs. Deline answered. "Who else?"
+
+Penny set the hamper on the table. Deliberately she raised the lid. The
+basket was filled with food, enough for a dozen persons, and in the
+bottom she saw a folded wool blanket. Beneath the blanket were several
+bulky garments which she took to be men's clothing. Before she could see
+plainly, Mrs. Deline jerked the lid of the hamper into place.
+
+"Please!" she said with emphasis.
+
+"I was only trying to be helpful," Penny said, pretending to look
+injured. "Don't you want Lou and me to dust off the table and spread out
+the picnic things?"
+
+"I do not. If you'll excuse me for saying so, I came on this picnic to be
+alone. I enjoy solitude."
+
+"But it's getting dark," Penny argued. "We wouldn't think of deserting
+you. The cabin has no light."
+
+"I don't mind the dark. Anyway, I brought candles. I really prefer to be
+alone."
+
+Thus dismissed, Louise started to leave. Penny lingered, trying to think
+of some excuse. Just then, from somewhere in the woods, she heard a
+shrill whistle unlike any bird call.
+
+"What was that?" she asked alertly.
+
+"I heard nothing," said Mrs. Deline.
+
+Nevertheless, a moment later the woman sauntered to an open cabin window.
+Deliberately she turned her back to the girls, trying to block their
+view. Quickly she raised and lowered her handkerchief.
+
+The movement was deftly executed, but swift though it was, Penny saw and
+understood. Mrs. Deline had signaled to an unseen person beyond the
+fringe of trees!
+
+
+
+
+ CHAPTER
+ 16
+ _SUSPICION_
+
+
+Penny moved swiftly to the open cabin door, gazing toward the darkening
+woods. No one was visible amid the shadows. Yet she was certain that Mrs.
+Deline had signaled to someone lurking among the trees.
+
+The widow had turned from the window to unfasten the lid of the picnic
+hamper.
+
+"Since you girls are here you may as well stay and share my supper," she
+said without warmth. "There's enough food for all."
+
+Louise's chin tilted proudly. The invitation was grudgingly given, and
+she meant to decline. Penny forestalled her by saying:
+
+"How nice of you, Mrs. Deline! Of course we'll be delighted to remain."
+
+Mrs. Deline made no reply, though obviously she had not expected an
+acceptance. Irritably she laid out the picnic dishes--sandwiches, a
+salad, cake, cookies, and fruit--all carefully prepared and cooked at the
+hotel kitchen.
+
+"You certainly did bring plenty of food for one person," Penny commented,
+helping herself to a chicken sandwich. "Isn't that clothing in the bottom
+of the basket?"
+
+"Only a blanket." Mrs. Deline closed the lid firmly. "I thought I might
+need it if I should sit on the damp ground."
+
+Hungry as bears, Penny and Louise did not try to curb their healthy,
+young appetites. Mrs. Deline, on the other hand, scarcely nibbled at the
+food. Several times she arose and paced nervously to the window.
+
+"It's growing dark and I should return to the hotel," she said the
+instant the girls had finished eating. "I'll not bother to repack the
+lunch basket."
+
+"Oh, we'll help you pick up everything," Penny offered.
+
+"Please don't bother. I'll merely pay the hotel for the basket."
+
+Penny was convinced that Mrs. Deline deliberately intended to leave the
+hamper behind. Despite the deep inroads she and Louise had made,
+considerable food remained. It occurred to her that the widow hoped to
+leave what remained so that the person hiding in the woods might come to
+the cabin for it after the party had gone.
+
+"I can't be bothered with a heavy basket," Mrs. Deline said impatiently.
+"We'll just leave it on the table."
+
+"Oh, the rangers wouldn't like to have us leave food here," Penny
+protested. "It will only take a minute to clean up everything."
+
+Disregarding Mrs. Deline's order, she began to repack the remains of the
+lunch.
+
+"But I don't wish to carry the basket all the way to the hotel!"
+
+"Louise and I will help you."
+
+Tossing her head, Mrs. Deline walked out of the cabin, allowing the door
+to slam behind her. Louise and Penny finished packing the lunch and
+hastened down the trail in pursuit.
+
+"Maybe we shouldn't cross her so," Louise whispered uneasily. "I think
+she intended to meet someone here!"
+
+"I'm sure of it," agreed Penny. "We spiked her little plan. I have an
+idea who she intended to meet too!"
+
+"Who?"
+
+Penny could not answer, for by this time she and Louise were practically
+at Mrs. Deline's heels. The widow was walking as fast as she could.
+
+"You'll have to keep the basket," she told the girls irritably. "I'm sure
+I'll never carry it back to the hotel."
+
+All the way to the Parker camp Mrs. Deline ignored Penny and Louise. And
+as they bade her goodbye, she barely responded.
+
+"Can't we drive you down to the hotel in the car?" Penny offered, feeling
+slightly ashamed of her actions.
+
+"Thank you, no," the widow answered icily. "You've done quite enough for
+one day." She vanished down the darkening road.
+
+After Mrs. Deline was beyond view, the girls retraced their way to the
+spring for the water bucket. As they approached, they thought for a
+moment that they heard retreating footsteps. The realization that they
+were alone in the woods, made them a bit nervous. Hurriedly they
+recovered the bucket and carried it to camp.
+
+"Now tell me what you think, Penny!" Louise commanded when they were
+inside the tent.
+
+"Why, it's clear as crystal." Penny struck a match to the wick of the
+gasoline lantern and hung it on a hook of the tent pole. "Mrs. Deline
+went to the cabin intending to meet someone. She carried extra food, a
+blanket, and if I'm not mistaken, clothing for a man."
+
+"You thought she signaled from the window?"
+
+"I'm sure she did, Lou. She warned the person, whoever he was, not to
+approach. She hoped by leaving the basket behind to get it into his hands
+after we'd gone."
+
+"You thwarted her in that."
+
+"We did together," Penny chuckled. Her face suddenly became sober.
+"Lou--"
+
+"Yes?"
+
+"It just occurred to me! Maybe the man she intended to meet was the same
+fellow who stole food from our camp."
+
+"That's possible. But why should Mrs. Deline be interested in a common
+tramp?"
+
+"How do we know that fellow was a tramp?" Penny speculated. "Jerry told
+us about a young soldier that had escaped from a Canadian prison camp.
+Mrs. Deline may be trying to help him by supplying food and heavy
+clothing!"
+
+"As usual, Penny, aren't you leaping to hasty conclusions?"
+
+"Maybe I am, but everything fits in beautifully. I've thought from the
+first that Mrs. Deline was nothing less than a spy or an international
+crook."
+
+"You've aired that theory before," Louise said, stretching out on the
+cot. "Wonder when your father will get here?"
+
+"I wish he would come," Penny replied, glancing anxiously toward the
+road. "At least I have one consolation."
+
+"What's that?"
+
+"I know he's not with Mrs. Deline. Oh, Lou, think how horrible it would
+be to have a spy for a stepmother!"
+
+"It would be something different anyhow," Louise chuckled. "Want to
+listen to the radio awhile?"
+
+"Okay," Penny agreed, "maybe we can tune in that outlaw station. It's
+about time for the regular nightly broadcast."
+
+Closing themselves into the car, the girls tried without success to get
+the outlaw shortwave station. Tuning instead to a dance orchestra, they
+discussed the day's happenings and made elaborate plans for the morrow.
+
+"I'm really going to work," Penny announced grimly. "No Mrs. Deline ever
+will outwit me! Our first job must be to find that package she buried in
+the sand."
+
+"And what of the person hiding in the woods?"
+
+"The rangers ought to take over that part." Penny peered out through the
+car window at the dark woods which hemmed in the camp. "Somehow," she
+admitted, "I don't like the idea of being here at night. I'm not exactly
+afraid, but--"
+
+"Listen!" Louise ordered sharply, "Someone's coming!"
+
+Penny snapped off the radio. Tensely, the girls watched the road. The
+next instant they relaxed, for it was Mr. Parker who trudged wearily up
+the slope. Seeing Penny and Louise in the car, he came over to apologize
+for being so late.
+
+"I've been with Jerry for the past two hours," he explained. "Time went
+faster than I realized."
+
+"Any news?" Penny asked eagerly.
+
+"Not about the radio station if that's what you mean. The fellow got away
+with his portable outfit slick as a whistle."
+
+"The authorities have no idea who the man is, Dad?"
+
+"Not the slightest. So far they've not been able to break the code he
+uses either. But in time they'll get him."
+
+Having gleaned what information they could from Mr. Parker, the girls
+related their own adventure. As they fully expected, he made light of the
+episode at the cabin.
+
+"Why should Mrs. Deline expect to meet anyone there?" he argued. "Penny,
+I'm afraid you don't understand her and misinterpret her actions."
+
+"I don't understand her, that's certain."
+
+"As to a man loitering about the camp," Mr. Parker resumed, "I've been
+worried about that ever since food was stolen. As I must be gone so much
+of the time, why wouldn't it be better for us to move to the hotel?"
+
+Penny stiffened for an argument, and then suddenly changed her mind.
+
+"All right, Dad," she astonished him by saying, "as far as I'm concerned,
+we can move tomorrow. I've had enough of the lonesome life."
+
+"Why, that's fine!" Mr. Parker said heartily. "Splendid!"
+
+After he had moved on, to sit for awhile by the dying embers of the fire,
+Louise remarked to Penny that explanations were in order.
+
+"How come you're ready to desert the rough and rugged life?" she
+demanded. "At first you were dead set against moving into the hotel."
+
+Penny carefully raised the car window so that her father would not
+overhear.
+
+"I believe in fighting the Enemy on his own territory," she explained
+elaborately. "Mrs. Deline will bear watching. I intend to devote all my
+waking hours to the cause."
+
+"So Jerry has nothing to do with it?"
+
+"Jerry?"
+
+"You wouldn't want to move to the hotel so you'd see more of him?"
+
+"What an idea!" Penny scoffed. "Whoever thought of such a thing!"
+
+"You did or I'm no mind reader."
+
+"Well, it may have crossed my mind," Penny acknowledged with a giggle.
+"In fact, I can see quite a few advantages to hotel life. With luck we'll
+yet make something of this vacation!"
+
+
+
+
+ CHAPTER
+ 17
+ _VISITORS NOT PERMITTED_
+
+
+Penny stood before the mirror in the hotel room and struggled to coax a
+little curl into her damp hair. She and Louise had spent two hours
+splashing in the surf that morning. The salt water had tightened their
+skins and produced discouraging results with their tresses.
+
+"This place does have it over a forest camp," Penny said, gazing about
+the comfortably furnished room she shared with Louise. Her father's room
+was three doors down the hall. "A shower bath, no meals to cook, no
+dishes to wash, and the sea at one's elbow."
+
+"I like it better," replied Louise. She had curled up kitten fashion on
+the bed and was making deep inroads into a box of chocolates. "So far
+though, we've not done much fancy sleuthing."
+
+"We've only been here a few hours. Where do you suppose Mrs. Deline keeps
+herself?"
+
+"In her room no doubt. Why do you worry about her so much, Penny?"
+
+Penny twisted a few ringlets over her finger and abandoned the project as
+hopeless. "Lou, you know all the prize answers without asking me," she
+said. "I've told you a dozen times why I distrust that woman."
+
+"Doesn't it all simmer down to one thing? You're jealous as a green-eyed
+cat!"
+
+"Maybe I do dislike her," Penny grinned. "On second thought, I'm sure of
+it! But facts are facts and have nothing to do with my personal feelings.
+In the first place, didn't she get Dad to bring her with us to Sunset
+Beach?"
+
+"But what does that prove? She has no car of her own and the trains are
+so crowded."
+
+"I think she knew that Dad was coming here to try to dig up a story about
+the outlaw radio station," Penny went on, unruffled. "She's probably
+pumped him of information."
+
+"Your father knows how to look after himself."
+
+"That's what _he_ thinks!" Penny muttered. "I wouldn't place any wagers
+on it myself. Why, he's been as blind as a bat."
+
+"I'm afraid you see enough for two or three people," Louise chuckled.
+
+"I told you, didn't I, how that vampire tried to steal our car while we
+were on our way here?"
+
+"Two or three times, darling."
+
+"Well, it would bear repeating. I think she intended to meet someone that
+night--perhaps the same person who was hiding in the woods!"
+
+Louise, methodically eating chocolates, mulled over the possibility.
+
+"Jerry told us that an escaped flier from a Canadian prison camp may be
+hiding somewhere near here," Penny resumed, wandering to the window.
+"Perhaps Mrs. Deline is trying to help him!"
+
+"You have a new theory every minute," Louise yawned. "Why not think up
+one and stick to it?"
+
+Penny did not answer for at that moment she observed Jerry Livingston
+leaving the veranda of the hotel.
+
+"Come on, Lou!" she cried, jerking her chum off the bed. "I want to see
+Jerry before he escapes!"
+
+"Talk about Mrs. Deline pursuing your defenseless father!" Louise
+protested as she was pulled down the hall to the elevator. "Her tactics
+at least are more subtle than yours!"
+
+"This is different," Penny retorted shamelessly. "Jerry and I are old
+friends."
+
+Swinging through the revolving doors of the hotel, the girls raced after
+Jerry. Breathless from running, they finally overtook him far down the
+boardwalk.
+
+"Why, hello," he greeted them with a broad smile. "I hear you've moved
+into the hotel."
+
+"Lock, stock and barrel," Penny laughed. "We want to be in the thick of
+things. Any news about the radio station?"
+
+"Nothing I can report, I'm on my way now to Intercept Headquarters."
+
+"Did you see Dad this morning?"
+
+"Only for a few minutes. He's doing a little special work for me."
+
+"At least I'm glad it's for you and not Mrs. Deline," Penny said stiffly.
+"Jerry, there are some things you should know about that woman."
+
+"Suppose you unburden your heart," Jerry invited, seating himself on a
+sand dune. "I have about ten minutes to listen."
+
+"Don't encourage her," sighed Louise. "She's slightly cracked on the
+subject, you know."
+
+"Nevertheless, Penny has ideas at times," Jerry paid her tribute.
+"Shoot!"
+
+Talking like a whirlwind, Penny delved deeply into the subject of Mrs.
+Deline. She repeated how the widow had buried a package in the sand, but
+it was not until the episode of the cabin was described that Jerry really
+seemed interested.
+
+"Penny, at first I didn't take your Mrs. Deline talk very seriously," he
+admitted. "Perhaps you have something after all!"
+
+"I'm sure of it, Jerry!"
+
+"Have you reported to the park rangers?"
+
+"Dad may have seen them, I'm not sure. We left camp in a big rush."
+
+"Then I'll take care of that, Penny. We'll have the park searched again
+and try to find that fellow!"
+
+"Then you do believe he's the escaped flier!" Penny exclaimed.
+
+"Probably not," was Jerry's discouraging reply. "Nevertheless, we can't
+afford to overlook any possibility."
+
+"What about the package in the sand?"
+
+"You remember where it was buried?"
+
+"Approximately."
+
+"I'll not have time to go with you now," Jerry said, looking at his wrist
+watch.
+
+"Louise and I haven't much to do this morning. We'll be glad to search."
+
+"Go ahead," Jerry urged. "If you fail then I can take over. The important
+thing is not to tip off your hand. Don't let anyone suspect what you're
+about."
+
+Penny and Louise nodded soberly. They felt rather important to have been
+assigned a definite task.
+
+"Report to me as soon as you find that package," Jerry urged as he
+started on. "It may contain something of vital importance. It may not.
+We'll withhold judgment until we have the facts."
+
+Left to themselves, the girls lost not a moment in hastening to the
+section of beach where Mrs. Deline had been seen to bury the package.
+
+"Now just where was it?" Penny asked, gazing about the deserted dunes.
+"What became of our marker?"
+
+"We left a stick to show the exact spot."
+
+"Not a sign of it now. What wretched luck!"
+
+Though the girls knew the general locality where the package had been
+buried, all of the dunes looked discouragingly alike. Not a footprint
+remained to guide them.
+
+"I'll bet a cent Mrs. Deline came back here and removed that stick!"
+Penny declared. "Maybe she dug up the package too!"
+
+"Anyone could have taken the stick. Why do you think she did it?"
+
+"Because she watched us digging for the package. Well, let's look for it
+anyhow."
+
+With none too much enthusiasm, the girls set to work. The tide was much
+lower than upon their last visit and the shoreline did not look the same.
+Nor could they agree within forty feet of the right place to dig.
+
+"You try one dune, and I'll work on another," Penny offered as a
+compromise.
+
+An hour of unavailing work found the pair too discouraged to keep on
+digging.
+
+"If this is the right place, Mrs. Deline or someone has removed the
+package," Penny declared, sinking back on her heels.
+
+"We may as well give up," Louise added wearily.
+
+Penny slid down the dune and emptied sand from her shoes.
+
+"There should be an easy way to beat Mrs. Deline at her own little game,"
+she remarked thoughtfully. "For instance, why does she always wear that
+jade green charm?"
+
+"Because she likes it I'd imagine."
+
+"But wouldn't you think she'd take it off at night?"
+
+"Perhaps she does, Penny."
+
+"Not the night I was with her. I distinctly gained the impression that
+there was something about it she was afraid I'd see."
+
+"A message contained inside?"
+
+"That's been my theory from the first, Lou. Now if only we could lay our
+hands on the charm--"
+
+"Finding the package would be a lot easier. We can't waylay the woman and
+take the jade elephant by force. Or can we?"
+
+"No," Penny agreed reluctantly, "I don't think Dad would like that. And
+there's always the possibility I might be wrong."
+
+"The probability, you mean," corrected Louise.
+
+Penny retied her shoes and glanced toward the hotel. Far up the beach she
+saw Mrs. Deline, and the widow was walking slowly toward the sand dunes.
+
+"Duck!" Penny ordered, rolling over one of the high ridges. "We don't
+want her to see us here. She'll suspect what we've been up to."
+
+Louise crouched behind the dune with her chum, though she complained that
+she felt silly doing it. Apparently, Mrs. Deline had not seen the girls.
+She came steadily on.
+
+Drawing close, she peered directly at the dune where the girls had taken
+refuge. For a second they feared that she had seen them. But she passed
+on without another glance.
+
+"It looks to me as though she's on her way to the lighthouse again,"
+Penny remarked after Mrs. Deline was far down the beach. "Wonder why she
+goes there so often?"
+
+"I thought visitors weren't allowed."
+
+"According to the rules they're not."
+
+From behind the dune, the girls kept watch of the widow. Presently they
+saw her climb the steps of the lighthouse and disappear into the
+interior.
+
+"Well, that settles it!" Penny exclaimed indignantly.
+
+"Settles what?" Louise straightened up, brushing sand from her skirt.
+
+"If Mrs. Deline can get into that lighthouse, so can I. We'll make an
+issue of it!"
+
+"Not today," said Louise dubiously.
+
+"Right now!" Penny corrected, starting down the beach. "That lighthouse
+is government property, and as citizens we have certain rights. Let's
+assert them and see what happens!"
+
+
+
+
+ CHAPTER
+ 18
+ _INSIDE THE LIGHTHOUSE_
+
+
+Unchallenged, Penny and Louise reached the base of the lighthouse. But as
+they slowly climbed the iron stairs, their courage fast slipped away.
+
+"What will we say to the keeper?" Louise faltered. "I've even forgotten
+his name."
+
+"I haven't," said Penny. "It's Jim McCoy. If Mrs. Deline is allowed
+inside the tower, shouldn't we have the same privileges?"
+
+"She's a personal friend."
+
+"That should make no difference," Penny argued. "This is government
+property."
+
+"Let's not do it," Louise pleaded, holding back.
+
+Having proceeded so far. Penny was in no mood to retreat. Quickly, lest
+she too lose her courage, she rapped hard on the tower door.
+
+Minutes elapsed. Then the heavy oak door swung back and Jim McCoy, the
+burly keeper, peered out at the girls. His bushy brows drew together in
+an angry scowl.
+
+"You here again!" he exclaimed.
+
+"Yes," said Penny, making the word crisp and firm.
+
+"I'll have to report you if you keep pestering me," the keeper scolded.
+"How many times have I told you no visitors are allowed?"
+
+"But you don't treat everyone the same!" Penny remonstrated. "Mrs. Deline
+just came here."
+
+"Mrs. Deline? Who's she?"
+
+"Why, a woman who stays at the hotel. She came through this door not five
+minutes ago!"
+
+"You must have imagined it. I've had no visitors."
+
+Penny's silence said more plainly than words that she did not believe the
+keeper.
+
+"So you think I'm lying, eh?" he demanded unpleasantly. "Okay, come in
+and see for yourselves. I'm breaking a rule to invite you into the tower,
+but maybe then you'll be satisfied and quite bothering me. We have work
+to do here, you know."
+
+The keeper stepped aside so that the girls might enter.
+
+"My living quarters," he said curtly. "You see, I have no visitors."
+
+Decidedly ill at ease, the girls gazed about the little circular room.
+The walls were lined with built-in cupboards. Nearly all of the furniture
+had been made with a view to conserving space. As Mr. McCoy had said,
+there were no visitors--no evidence that Mrs. Deline ever had been there.
+
+"Are you satisfied?" the keeper demanded unpleasantly.
+
+"But we were sure Mrs. Deline came here," Penny stammered.
+
+"There's been no one today except early this morning when a government
+inspector paid me a visit."
+
+Penny did not believe the man but she deemed it wise to appear to do so.
+
+"I'm sorry," she apologized. "I guess we have made nuisances of
+ourselves."
+
+"That's all right," the keeper said in a less unfriendly tone. "Kids are
+kids. Now that you're here, look around a bit."
+
+"Oh, thank you," Louise replied gratefully. "I've always wanted to see
+the inside of a lighthouse."
+
+"I have some work to do," Mr. McCoy announced. "The light's not been
+operating right and I'm trying to get the mechanism adjusted. I'll be
+back."
+
+He went out, allowing the door to slam hard.
+
+The girls surveyed their surroundings with keen interest. On a table near
+the window there was a shortwave radio. A circular couch occupied another
+curving corner of the room.
+
+"What became of Mrs. Deline?" Penny whispered. "She certainly came here."
+
+"Of course she did! We saw her plain as day!"
+
+"She must be somewhere in the tower. Probably there's a room above this
+one."
+
+Penny tiptoed to the door and tried to open it. To her surprise and
+chagrin, it would not budge.
+
+"My Great Aunt!" she whispered. "We're locked in!"
+
+"Maybe the door's just stuck." Louise strode across the room to help
+Penny. Both of them tried without success to open it.
+
+"Let's shout and pound!" Louise suggested.
+
+"No, wait! I think we've been locked in here on purpose."
+
+"Oh, Penny!"
+
+"Now don't get nervous. The keeper's no fool. He'll have to let us out."
+
+"But why would he lock us in?"
+
+"Because he's provoked at us for one reason, Lou. Another, something's
+going on here that he doesn't want us to know about. He and Mrs. Deline
+may be having a tete-a-tete in the room above."
+
+"Then let's listen. Maybe we can overhear their conversation."
+
+Penny nodded and fell silent. Though the girls listened for a long while,
+no sound reached their ears.
+
+"This is a nice situation!" Louise fumed. "I think the door locked
+itself. We ought to shout for help."
+
+"Goose, a door doesn't lock itself."
+
+"This one might have a trick catch."
+
+"It was Mr. Jim McCoy who accomplished the trick," Penny said. "Listen!
+Someone's coming now."
+
+Plainly the girls could hear footsteps on the iron balcony outside the
+door. A moment later they were able to distinguish a murmur of men's
+voices. The footsteps moved on and a moment later they heard a door close
+overhead.
+
+"Another visitor!" Penny announced. "Did you hear what was said, Lou?"
+
+"Couldn't make out a word."
+
+"Nor could I. But that voice sounded familiar. I'm sure I've heard it
+somewhere."
+
+"I had the same feeling, Penny."
+
+The girls listened intently, hoping to overhear conversation on the floor
+above. However, the walls of the lighthouse were so thick that not a word
+reached them. Now and then they thought they heard Mrs. Deline's high
+pitched voice.
+
+"Louise, it's just come to me!" Penny whispered a moment later. "I
+believe Mr. McCoy's visitor may be George Emory!"
+
+"The voice did sound a little like his. But why would he come here?"
+
+"Maybe we've under-rated George Emory. Why, all this time he may have
+been trying to get information from us."
+
+"He did ask us quite a few questions, particularly about your father."
+
+"And he seemed to know a lot about that outlaw radio station, Lou. Maybe
+he tried to throw us off the track by suggesting that we watch old Jake
+Skagway."
+
+"We certainly fell for it, Penny."
+
+"We did, if you assume that George Emory is upstairs having a conference
+with Mrs. Deline and the lighthouse keeper. But we're not sure."
+
+"No, we're not, Penny. One easily can be mistaken in voices."
+
+Determined to hear more, Penny cautiously climbed up on the radio table,
+so that her head and ear were close to the ceiling.
+
+"Can you make out anything?" Louise whispered.
+
+Penny shook her head in disgust. After a few minutes she dropped lightly
+down from the table.
+
+"Walls are too thick," she announced. "I could hear three voices though.
+Two were men and the other, a woman."
+
+"Then Mrs. Deline must be here. The keeper lied about that part."
+
+Presently the girls heard footsteps again on the iron stairway. They
+moved to the window, hoping to see whomever was descending from the room
+above. However, the little round aperture was so situated that it gave a
+view of only one side of the Point. They could not see the stairway nor
+the stretch of beach leading to the hotel.
+
+"We're certainly learning a lot!" Louise said crossly. "I've had enough
+of this. Let's shout for help."
+
+"All right," Penny agreed. "We may as well find out whether or not we're
+prisoners."
+
+Crossing to the heavy oak door, she pounded hard on the panels. Almost at
+once the girls heard someone coming.
+
+"Don't let on what we suspect," Penny warned her companion.
+
+The next moment the door swung open to admit the keeper of the light.
+
+
+
+
+ CHAPTER
+ 19
+ _A LOCKED DOOR_
+
+
+"I was gone a little longer than I meant to be," Jim McCoy apologized as
+he came into the room. "Did I keep you waiting?"
+
+"We probably wouldn't have waited if you hadn't locked the door!" Louise
+said sharply.
+
+The keeper's eyebrows lifted and he looked slightly amused. "Locked in?"
+he echoed.
+
+"Yes, we couldn't get the door open."
+
+"Oh, it sticks sometimes. Been intending to fix it for several days. If
+you had pushed hard it would have opened."
+
+"We certainly pushed hard enough," Penny said dryly. She was more than
+ever certain that the lighthouse keeper had unlocked the door only a
+moment before entering. Clearly, he had meant to prevent Louise and her
+from seeing and hearing what went on in the room above.
+
+"Come along," the keeper invited. "I'll show you the tower."
+
+"No thank you," Penny replied coldly. "We've spent so much time here that
+we'll have to be getting back to the hotel."
+
+"As you like." The keeper shrugged, and looked relieved by the decision.
+
+Jim McCoy stepped away from the door, and the girls hastened down the
+iron stairway. No one was in sight on the beach. Whoever had visited the
+lighthouse during the time they were imprisoned, had disappeared.
+
+When they were well down the beach, Louise and Penny slackened their
+pace. Glancing back they saw that the keeper of the light still stood on
+the tiny iron balcony watching them.
+
+"That man gives me the creeps," Louise remarked. "Did you believe what he
+said about the door sticking?"
+
+"I did not," Penny returned with emphasis. "I think he locked us in on
+purpose, probably because he was expecting visitors and didn't want us to
+see too much."
+
+"As it turned out we didn't learn a thing."
+
+"We have no proof of anything," Penny admitted slowly. "Nevertheless,
+we're pretty sure Mrs. Deline visited the tower."
+
+"George Emory too."
+
+"That part is pure guess," Penny said, "so we don't dare consider it too
+seriously. Did you ever see Mrs. Deline with George Emory?"
+
+"Why, no. But then, we've not been at the hotel long."
+
+"Let's find Jerry or Dad," Penny said abruptly. "We ought to report to
+them."
+
+Returning to the hotel, the girls looked in vain for Mr. Parker. The
+publisher was not in his room nor anywhere in the lobby. Jerry apparently
+had not returned from Intercept Headquarters.
+
+"There's Mrs. Deline," Louise whispered, jerking her head toward a
+high-backed chair not far from the elevator.
+
+The widow was reading a newspaper. If she saw the girls she paid no
+attention to them.
+
+"Let's talk to her and see what we can learn," Louise suggested.
+
+Penny had another thought. "No," she vetoed the suggestion. "Mrs. Deline
+would be more likely to learn things from us. That woman is clever."
+
+Just then Mrs. Deline arose, picked up her purse, and went out the front
+door of the hotel. On their way to the elevator. Penny and Louise noticed
+that the woman carelessly had left a handkerchief and her room key lying
+on the chair.
+
+"I'll turn them in at the desk," Louise said, picking up the articles.
+
+"Wait, Lou!"
+
+Louise glanced at her chum in surprise.
+
+"I have an idea!" Penny revealed, lowering her voice. "Are you game to
+try something risky?"
+
+"Well, I don't know."
+
+"This chance is tailor-made for us!" Penny went on. "Mrs. Deline simply
+handed her room key over to us. Let's use our opportunity."
+
+"Enter her room?" Louise asked, shocked.
+
+"Why not? FBI agents think nothing of examining the belongings of a
+suspected person."
+
+"But we're not FBI agents, Penny. I don't want to do it without asking
+Jerry."
+
+"By that time it will be too late. It's now or never."
+
+"Mrs. Deline might catch us in the act."
+
+"That's a chance we'll have to take." Penny, in possession of the room
+key, walked to the front door of the hotel. She was reassured to see that
+Mrs. Deline had seated herself on a bench some distance from the veranda.
+
+"The coast's clear," Penny reported, coming back to Louise. "What do you
+say?"
+
+"Well, I suppose so," Louise consented nervously.
+
+An elevator shot the girls up to the fourth floor. To locate Mrs.
+Deline's room required but a moment, and the halls fortunately were
+deserted. Penny fitted the key into the lock and pushed open the door.
+
+"We'll have to work fast," she said, closing it behind them again.
+
+The room was in perfect order. Only a few toilet articles had been set
+out on the dresser. Mrs. Deline's suitcase was only half unpacked.
+
+"It looks to me as if the widow is holding herself ready to fly at a
+moment's notice," Penny commented. "Otherwise, why didn't she unpack
+everything?"
+
+"What do you expect to find here?" Louise asked nervously. "Let's get it
+over with fast, Penny."
+
+"Start with the bureau drawers," Penny instructed. "Search for any
+papers, letters or the sort. I'll go through the suitcase."
+
+Carefully the girls began examining Mrs. Deline's personal belongings.
+Almost at once Louise reported that the bureau contained nothing of
+interest. Penny, however, had more luck. She came upon a pearl-handled
+revolver buried beneath a pile of silk underclothing.
+
+"Jeepers!" she whispered, touching the weapon gingerly. "Now will you
+believe me when I say that the widow isn't the sweet little girl she'd
+have us believe!"
+
+Louise's eyes had opened wide at sight of the revolver.
+
+"And here's that white suit she wore!" Penny cried, lifting out a folded
+garment from the suitcase. "Look, Lou!"
+
+From the skirt of the suit had been cut a neat, square hole.
+
+"Well, of all things!" Louise exclaimed. "What's the meaning of that?"
+
+"Mrs. Deline wrote something on the skirt--don't you remember? Probably
+she used a pen with invisible ink."
+
+"But why on her skirt, Penny?"
+
+"She'd just been to the lighthouse. Perhaps she learned something there
+and she wanted to write it down before she forgot. Possibly she didn't
+have any paper. Then when she got back here, she either destroyed the
+message, or sent it to someone."
+
+"Well, I don't know," Louise said doubtfully. "It's all so fantastic. I
+wouldn't believe a bit of it except for this revolver. Having it doesn't
+look so good."
+
+"And don't forget the green elephant charm," Penny reminded her. "I wish
+we could find it here."
+
+"Not a chance. Mrs. Deline always wears it around her neck. She had it on
+today. I noticed."
+
+Time fast was elapsing and the girls were worried lest someone discover
+them in the room. Hastily they replaced everything as they had found it,
+and relocking the door, stepped out into the hall.
+
+"What's our next move?" Louise asked as they buzzed for a down-going
+elevator.
+
+"To tell Jerry and Dad, of course. But before that, there's one thing I
+wish we could do, Lou. It would give everything we have to report a more
+substantial basis."
+
+"What's that, Penny?"
+
+"Why don't we get our hands on the jade green elephant? I've a hunch that
+it contains something important--perhaps evidence that would crack the
+case wide open."
+
+"And just how do you propose that we acquire the charm?" Louise asked
+sarcastically. "Are we to waylay Mrs. Deline and take it by force?"
+
+"Afraid that wouldn't do."
+
+"There's no other way to get it. Mrs. Deline wears that charm as if it
+were her skin. I've never seen her without it."
+
+The elevator was coming down so Penny spoke hurriedly.
+
+"There is a way," she said softly, "if only it will work. Think we could
+get Mrs. Deline to go bathing in the surf with us?"
+
+"And ruin that lovely hair-do? Don't be silly."
+
+"All the same, it's worth trying," Penny urged. "Let's go to our room now
+and get our bathing suits."
+
+"I don't see any point in it."
+
+"You will," Penny laughed, entering the elevator. "If my little plan
+works we'll have keen sport and maybe do our country a good turn!"
+
+
+
+
+ CHAPTER
+ 20
+ _NYMPHS OF THE SEA_
+
+
+"How you expect to get Mrs. Deline to go swimming with us is beyond me!"
+Louise opined as she and Penny left the hotel, their bathing suits
+swinging over their arms. "It's none too warm today. She dislikes us both
+intensely. Furthermore, she never swims."
+
+"Any other reasons?" Penny asked cheerfully.
+
+"That should be enough."
+
+"Just wait and watch," Penny chuckled. "I just hope she doesn't suspect
+we've been prowling in her room. If she got wise to that she'd report us
+to the hotel management."
+
+Before leaving the hotel the girls had taken care to drop the room key in
+the chair where Mrs. Deline had left it. They were confident that no one
+had seen them take the key or enter the room.
+
+The widow remained as the girls last had seen her. She was sitting on a
+bench facing the sea, her gaze fixed on the deep blue line of the
+horizon. As the girls passed beside her, she looked up, frowning
+slightly.
+
+"We're on our way to the bath house," said Penny, her tone implying that
+the matter was one of great importance.
+
+"Really?" Mrs. Deline's voice barely was polite.
+
+"Wouldn't you like to come with us?" Louise invited cordially.
+
+The invitation took Mrs. Deline by surprise. "No, thank you," she
+declined. "I can't swim."
+
+"We'll teach you," offered Penny.
+
+"You're too kind. I don't care for the water. I particularly detest cold
+water."
+
+"The air is warming up," Penny tried to encourage her. "Why not try it
+with us?"
+
+"Nothing could induce me."
+
+Louise nodded grimly, as much as to say that she had known how it would
+be. Penny would not give up. She decided to adopt drastic measures.
+
+"No, I didn't suppose you would go into the water," she said. "You're
+probably afraid you'll get salt water on that lovely skin of yours, or
+muss up your hair."
+
+"Oh!" gasped Mrs. Deline. "The very idea!"
+
+"Isn't that the reason?" Penny pursued ruthlessly. "You have to protect
+your beauty?"
+
+"No, it's not the reason!" Mrs. Deline snapped. "If I had a bathing suit,
+I'd show you!"
+
+"You can use mine," Penny said promptly. "Louise has an extra one she'll
+let me have."
+
+Mrs. Deline looked trapped and angry. She sprang to her feet.
+
+"All right, I'll go swimming!" she announced. "If I catch pneumonia I
+suppose you'll be satisfied!"
+
+"Oh, you'll love the water once you're in," Penny said sweetly. "The bath
+house is this way."
+
+Mrs. Deline spent so long getting into the borrowed suit that the girls
+began to fear she had outwitted them. But just as they were ready to give
+up, the woman came out of the dressing room. Penny's suit was a size too
+small for her so that she looked as if she had been poured into it. Her
+legs were skinny, her hips bulged. She still wore the elephant charm.
+
+"Don't I wish Dad could see her now!" Penny muttered. "What a
+disillusionment!"
+
+Ignoring the girls, Mrs. Deline walked stiffly toward the surf. A wave
+rolled in, wetting her to the knees. Mrs. Deline shrieked and backed
+away.
+
+"It's freezing!" she complained.
+
+"You have to get wet all at once," Penny instructed kindly. "This way."
+
+She seized Mrs. Deline's hand and pulled her toward the deeper water.
+
+"Let me go!" Mrs. Deline protested, trying to shake free. "Stop it!"
+
+Penny held fast to her hand. A big roller broke over their heads. Mrs.
+Deline sputtered and choked and struggled.
+
+"Oh, this is dreadful!" she whimpered.
+
+"You have to watch for the waves and jump just as they strike you," Penny
+laughed. "Now!"
+
+She leaped, but the widow mistimed the roller. It struck her a resounding
+whack on her shoulders and head.
+
+"Oh! Oh!" she moaned.
+
+"Here comes another!" warned Louise. "A big one too!"
+
+Mrs. Deline broke away from Penny. She started to run for shore. The big
+roller overtook her, sweeping her from her feet.
+
+This was the opportunity that Penny awaited. Pretending that she too had
+lost her balance, she allowed the tide to carry her straight into Mrs.
+Deline. For an instant they both were beneath the surface of the water.
+
+Penny worked fast. Clutching Mrs. Deline as if in terror, she yanked hard
+at the slender chain that held the green elephant charm. It snapped and
+the jade piece came off into her hands. Deftly she thrust the charm into
+the front of her bathing suit. Then she popped up above the water,
+winking at Louise.
+
+Mrs. Deline scrambled to her feet, clutching at the broken chain.
+
+"See what you've done!" she accused Penny. "You pulled it apart. My
+beautiful charm has fallen into the water!"
+
+"Let me help you look for it," Louise offered, darting forward.
+
+As the pair were groping about on the sandy floor, another wave rolled
+in. Penny neglected to warn Mrs. Deline. It struck her from behind,
+toppling her over on her face. Her cap slipped awry and she swallowed
+salt water.
+
+"Oh, I can't stand any more of this!" she spluttered. "It was cruel of
+you to get me to come into the surf! Now I've lost my charm, and it was
+all your fault, Penny Parker."
+
+"I'll buy you another ornament," the girl offered. Seeing Mrs. Deline's
+distress she felt a bit ashamed of herself.
+
+"Another ornament!" the widow mocked. "I don't want another! I want the
+one I've lost. It's of vital importance to me to keep it."
+
+Mrs. Deline made another futile search for the charm.
+
+"It's been washed away," she cried. "I'll never find it now!"
+
+Glaring furiously at Penny, she turned and fled to the bath house.
+
+"Did she really lose the charm?" Louise demanded the moment the girls
+were alone. "Or did you get it, Penny?"
+
+Penny answered by producing the green elephant charm from the front of
+her bathing suit where she had hidden it.
+
+"Easy as taking candy from a babe," she chuckled. "My, but was she
+hopping mad!"
+
+"You may not be laughing if your father hears about this," Louise warned.
+"He's apt to look at matters from a different angle than we do."
+
+Penny skipped through the shallow water and sat down on the beach well
+beyond the reach of the waves. Louise flopped beside her. Eagerly they
+examined the jade green trinket.
+
+"Looks like any ordinary charm to me," Louise remarked. "No special
+carving."
+
+"It should open," Penny said. "The first night when Mrs. Deline and I
+shared a room, I was sure I saw her close it."
+
+Louise turned the charm over and pried at it with a hairpin.
+
+"It does have a back lid!" she exclaimed excitedly. "Penny, I think it's
+going to open!"
+
+"I'll say magic words while you work," Penny laughed. "Furthermore, I'll
+keep watch of the bath house. We don't want Mrs. Deline to pop out here
+and see us."
+
+Louise pried again at the lid of the charm. It gave suddenly.
+
+Inside the tiny cavity was a folded piece of paper. While Louise stared
+in delighted awe, Penny gained possession. With nervous haste she
+unfolded the paper. She gazed at it a moment and her face fell.
+
+"Why, I can't make anything of the writing!" she declared in
+disappointment. "The words don't make sense."
+
+"Just a mess of letters," Louise agreed, peering over her shoulder.
+
+The girls were decidedly let-down for they had gone to much trouble and
+risk to obtain the jade ornament. But Penny's disappointment did not last
+long. As she stared at the paper, its significance dawned upon her.
+
+"Why, this is important, Lou!" she cried. "Maybe we've stumbled into
+something big!"
+
+"How do you mean?"
+
+"Don't you see?" Penny demanded triumphantly. "The letters, of this
+message must comprise a secret code! If only we can break it down we may
+learn all we need to know about Mrs. Deline and her strange friends!"
+
+
+
+
+ CHAPTER
+ 21
+ _THE CARDBOARD BOX_
+
+
+While Penny and Louise were puzzling over the strange writing found
+inside the jade charm, Mrs. Deline appeared in the doorway of the bath
+house. Barely in time to escape detection, the girls hid the tiny
+elephant and the paper in the sand.
+
+Mrs. Deline crossed the beach to speak to the girls. Her hair was damp
+and stringy, her face pinched and blue from cold.
+
+"Here's your suit!" she snapped, slapping the wet garment into the sand
+at Penny's feet. "I hope you enjoyed the swim! I'm sure I didn't."
+
+Turning her back, the widow marched to the hotel.
+
+The moment Mrs. Deline had disappeared into the white brick building,
+Penny dug the jade elephant and paper from the sand.
+
+"Let's get dressed," she urged Louise. "We've no time to waste."
+
+So thrilled were the girls over what they had accomplished that they
+could talk of nothing else. Penny felt that by obtaining the jade
+elephant she had proven her case.
+
+"You thought I was only jealous of Mrs. Deline," she told Louise
+triumphantly as they dressed in adjoining booths. "Now what do you say?"
+
+"That you're a genius!" Louise praised. "Mrs. Deline certainly is mixed
+up in some shady business."
+
+Once dressed, the girls wrapped the jade elephant in a handkerchief and
+carried it to the hotel. Jerry was nowhere to be found, and a bellboy
+told Penny that her father had gone for a walk.
+
+"Perhaps we can work the message out ourselves," Penny suggested
+hopefully. "Let's try."
+
+In their hotel room, the girls spent an hour attempting to decipher the
+strange jargon of letters appearing on the paper. At the end of that
+time. Penny tossed aside her pencil in disgust.
+
+"This is a job for an expert," she declared. "I certainly don't classify
+as one."
+
+The telephone jingled. Penny answered it and was delighted to hear
+Jerry's familiar voice. He was down in the lobby and had been told that
+the girls wished to see him.
+
+"We certainly do!" Penny answered gaily. "Hold everything! We'll be with
+you in a jiffy."
+
+The elevator being entirely too slow, the girls raced down the stairs.
+Breathlessly they started to tell Jerry what they had learned.
+
+"Not here!" he said quickly. "Let's go outside where we won't be
+overheard."
+
+Once out in the open with no one close by, Jerry lent an attentive ear to
+Penny's tale of their afternoon adventure. He did not have much to say in
+return, but he studied the jade green elephant and the paper with deep
+interest.
+
+"You don't think it's anything?" Penny asked in disappointment.
+
+"On the contrary, it may be something of very great importance," he
+returned soberly. "I'll take this to Headquarters. We have an expert on
+codes who should be able to break it in a short while."
+
+The girls hoped that Jerry would invite them to accompany him, but he did
+not do so. Instead he said:
+
+"Penny, you were telling me that Mrs. Deline had buried a package in the
+sand. Any luck in finding it?"
+
+"Not a bit."
+
+"You don't think that she went back there and dug it up herself?"
+
+"We didn't see any footprints."
+
+"How did you mark the place?"
+
+"By a stick that someone removed."
+
+"Not a very reliable way to take observations," Jerry remarked. "Ever try
+the clock system?"
+
+The girls looked blank.
+
+"For example," Jerry illustrated, "imagine that the landscape is like the
+face of a clock. Now what do you see on the hour of two?"
+
+"I don't get it," Louise complained.
+
+"Oh, I do!" laughed Penny. "A big tree!"
+
+"That's right," agreed Jerry. "And at the hour of six?"
+
+"Why, a signboard!" chuckled Penny. "At the hour of seven there's a big
+sand dune!"
+
+"If you picture things in your mind as if they're on the face of a clock
+it's much easier to remember and keep them in proper proportion. Now,
+using that same system can you recall anything more about the place where
+Mrs. Deline buried the package?"
+
+"Not very much," Penny admitted. "I didn't take notations at the time."
+
+"Speaking of signboards, I remember one," Louise said thoughtfully. "It
+was a long distance back from the beach, slightly to the right. A
+cigarette advertisement."
+
+"That's right!" agreed Penny.
+
+"Perhaps that will help some," Jerry said. "We'll have to find the
+package."
+
+"Then you believe Mrs. Deline is an Enemy Agent?" Penny asked eagerly.
+
+"I've thought so for quite a while now," Jerry admitted. "I didn't say it
+for fear of building up your hopes. Anyhow, we've got to work quietly in
+this business."
+
+"Poor Dad," Penny murmured, "I'm afraid it will break him up to learn the
+truth. Do you say I should tell him right away, Jerry?"
+
+"Why not?" Jerry demanded, his eyes amused. "Your father may have a few
+things to break to you too, Penny."
+
+"Meaning what?"
+
+"I'll let your father do his own talking," Jerry said, getting up from
+the hotel bench. "Have to go now."
+
+"Wait!" Penny pleaded. "You've not told us anything. Do you think Mrs.
+Deline has been aiding that flier who escaped from a Canadian prison
+camp?"
+
+Jerry deliberately let the question pass. "Listen!" he said urgently. "I
+may not see you girls again until after dinner. Want to help me tonight?"
+
+"Doing what?" Penny asked.
+
+"I want you to lead me to the place where Mrs. Deline buried that
+package."
+
+"We'll do our best."
+
+"Then if I don't see you earlier, meet me here at nine o'clock. It should
+be dark by that time."
+
+"We'll be here," Penny promised, her eyes glowing.
+
+At dinner that night the girls told Mr. Parker of their appointment to
+meet Jerry. Penny would have explained about the package, but before she
+could do so, Mrs. Deline joined the group. Mr. Parker immediately invited
+her to dine with them. To the annoyance of Penny and Louise she accepted
+with alacrity.
+
+The girls fully expected that Mrs. Deline would make some reference to
+the incident of the afternoon. Instead she avoided the subject, talking
+of her experiences in China and the Orient. Despite their prejudice,
+Penny and Louise were compelled in all honesty to acknowledge to
+themselves that the widow was a brilliant, entertaining
+conversationalist.
+
+Over the coffee cups Mrs. Deline spoke casually of a play which was
+showing at the local theatre. Before Penny could say a word, Mr. Parker
+had suggested that he buy tickets for the night's performance.
+
+"I'd love to go," Mrs. Deline accepted instantly.
+
+"Good!" Mr. Parker, approved. "I'll get four tickets."
+
+"Two," Penny corrected grimly. "Louise and I already have an
+appointment."
+
+"That's so," Mr. Parker recalled belatedly.
+
+Mrs. Deline looked so pleased that Penny was sorely tempted to abandon
+the meeting with Jerry. Only the realization that the task ahead was
+vitally important, kept her silent.
+
+At eight o'clock Mr. Parker and Mrs. Deline left the hotel for the
+theatre. With an hour to kill, Penny and Louise were very restless. They
+read the evening paper and watched the clock.
+
+"Here's an interesting news item," Penny remarked, indicating a brief
+story on an inner page of the paper. "It says an enemy submarine was
+sighted not many miles from here--just off the coast."
+
+"Did they get it?" Louise inquired absently.
+
+"I guess not. The story doesn't say, except that the air patrol dropped
+bombs."
+
+"Wonder what a single sub was doing so close here?" Louise speculated.
+"Oh, well, we've nothing to fear."
+
+A clock chimed the hour of nine. On the first stroke, the girls arose and
+hastened to keep their appointment with Jerry. The night was closing in
+dark. Along the shore no lights were showing for the dim-out was rigidly
+enforced at Sunset Beach.
+
+"Where's Jerry?" Penny asked as they reached the bench where they had
+promised to meet him. "Hope he didn't forget."
+
+Ten minutes elapsed. Penny was examining the luminous dial of her wrist
+watch when someone came striding down the gravel path.
+
+"Hello," Jerry greeted the girls. "Sorry to have kept you waiting. All
+set for adventure?"
+
+"Lead on!" Penny laughed.
+
+Taking each of them by an elbow, Jerry guided the girls down the deserted
+beach. Twice they passed guards who merely stared and allowed them to
+pass unchallenged.
+
+"Any news about that code?" Penny questioned as they walked along.
+
+"It's a tough one to break," Jerry replied briefly. "Experts have been
+trying to take it apart ever since I left you girls this afternoon."
+
+"Then it really is something?" Penny asked, scarcely daring to hope.
+
+"It certainly is," Jerry replied heartily. "We're pretty sure now that
+Mrs. Deline is mixed up in a bad business. But we can't act until we know
+absolutely."
+
+"This will be a horrible shock to Dad," Penny remarked. "He's at the
+theatre with Mrs. Deline now."
+
+"At least she's out of the way, so there's no chance she'll see us at
+work," Jerry commented. "Think you can find the place to dig?"
+
+Penny had marked it well in her mind, but at night everything looked
+different. After some uncertainty, the girls agreed upon the dune where
+the package had been buried.
+
+"With the tide low we'll have plenty of time," Jerry said. "Well, let's
+go! Was the package buried deep?"
+
+"Not more than a foot," Penny supplied.
+
+"Then if it's here, we'll find it. Let's block this area off and cover it
+systematically."
+
+For an hour the trio toiled. Twice one of the beach guards passed by and
+Penny was surprised that he paid no heed to what they were doing.
+
+"Orders!" Jerry chuckled. "You didn't think we could come out here and
+prowl around without questions being asked? The guard was tipped off.
+He'll help us by whistling if anyone comes this way."
+
+Louise, who had been industriously digging, gave a low cry.
+
+"Find something?" Jerry demanded.
+
+"I'm not sure. I think so."
+
+The next instant Louise lifted a small package from its sand tomb. Before
+Jerry could warn her, she had torn apart the pasteboard cover.
+
+"Why, it contains pencils!" she exclaimed in disgust. "Pencils!"
+
+Jerry leaped to her side. One glance and he took the box from her.
+
+"Those objects may look like pencils," he drawled. "But take it from me,
+they're a bit more deadly."
+
+Penny had moved close. She and Louise stared in awe at the collection.
+
+"Bombs," Jerry explained briefly. "One of these little pencils contains
+enough explosive to blow us all to Kingdom Come!"
+
+
+
+
+ CHAPTER
+ 22
+ _UNFINISHED BUSINESS_
+
+
+The cardboard box contained in addition to the pencil bombs a shiny knife
+and several grooved, pear-shaped objects.
+
+"What are those?" Louise asked curiously. "They look like hand grenades."
+
+"That's what they are," said Jerry, lifting one from the box. "It's a
+mighty useful weapon for close fighting. A strong man can throw a grenade
+twenty-five to thirty-five yards and it does damage over a large area."
+
+Penny gingerly inspected one of the grenades.
+
+"It won't bite you," Jerry laughed. "Nor will it explode in your hand.
+When you're ready to throw a grenade you hold it with the lever under
+your fingers. Just before you toss it, pull the pin."
+
+"Isn't it apt to explode while you're holding it?" Penny asked dubiously.
+
+"Not while the lever is held. When the grenade leaves the hand, the lever
+flies off. Then the fuse ignites and in about seven seconds you have your
+explosion."
+
+"Nice little gadgets," Penny said. She replaced the grenade in its box
+and ran a finger over the sharp edge of the steel-bladed knife.
+
+"Mrs. Deline evidently planted these weapons here for someone else to
+use," Jerry remarked. "We'll put them back just as they were."
+
+"Put them back!" Penny echoed. "Why, Jerry, wouldn't that be playing
+right into their hands? Shouldn't we destroy these things?"
+
+"No, it's much wiser to have the place watched."
+
+Light dawned upon Penny. "Oh, I see!" she exclaimed. "In that way you
+hope to learn Mrs. Deline's accomplices!"
+
+"Exactly."
+
+Jerry replaced everything in the box which he carefully buried in the
+sand. Then he obliterated all freshly made footmarks.
+
+"It may be necessary to watch this place for days," he said thoughtfully.
+
+"And what of Mrs. Deline?" Penny asked. "Will she be allowed complete
+freedom?"
+
+"That's for my superiors to decide. It seems to me, though, that more is
+to be gained by allowing her to remain at liberty than by arresting her."
+
+"I'm all for jail myself," said Penny.
+
+"Just be patient," Jerry smiled. "And whatever you do, don't drop a hint
+to Mrs. Deline of what we suspect."
+
+"She knows I dislike her."
+
+"That's all right, but don't let her guess that you consider her guilty
+of anything more serious than making a play for your father."
+
+"What about Dad? Shouldn't I warn him?"
+
+"Let me take care of that part," Jerry smiled.
+
+"All right," Penny agreed reluctantly. "Just be sure that you don't muff
+it. Remember, you're playing with my future!"
+
+Jerry finished smoothing out the footprints in the sand and then escorted
+the girls to the hotel.
+
+"I must report to Headquarters without delay," he said, pausing at the
+hotel entrance. "Don't worry about the package. We'll have the place
+watched every minute."
+
+After Jerry had gone, Penny and Louise entered the hotel.
+
+"Is my father here yet?" Penny asked the desk clerk.
+
+"No, Miss. And there's a message for him. As soon as he comes in he's to
+call Major Gregg."
+
+Penny repeated the name thoughtfully. "That's a new one on me," she
+remarked. "Dad seems to have friends I know nothing about."
+
+"Oh, the Major comes to the hotel frequently," the clerk returned,
+smiling. "He and your father are well acquainted."
+
+As the girls crossed the lobby to a drinking fountain, Louise said
+teasingly:
+
+"I'm afraid you've lost track of your father lately, Penny. You've been
+so upset about Mrs. Deline that you've scarcely noticed anything or
+anyone else."
+
+"Dad's been holding out on me, that's evident. Wonder what he's to call
+Major Gregg about?"
+
+"Why not wait up and see?"
+
+"Not a bad idea," Penny approved instantly. "He and Mrs. Deline should be
+getting in anytime now."
+
+"I'm not waiting up," announced Louise with a sleepy yawn. "In fact, I'm
+on my way to bed this minute."
+
+To prove her words she started for the elevator. Penny debated whether or
+not to follow and finally decided to remain in the lobby.
+
+An hour elapsed. Penny was half asleep by the time Mrs. Deline and Mr.
+Parker entered the hotel together. They were chatting animatedly and
+would not have seen her had she not scrambled from the wing chair.
+
+Seeing Penny, Mrs. Deline quickly bade Mr. Parker good night and vanished
+into an elevator.
+
+"You shouldn't have waited up," Mr. Parker chided his daughter. "Why,
+it's nearly midnight."
+
+"There's an important message for you, Dad. You're to call Major Gregg."
+
+Mr. Parker looked disconcerted. "How long ago did that call come, Penny?"
+
+"About an hour ago. Or that's when I learned of it."
+
+Mr. Parker went quickly to a telephone booth and was gone for some time.
+When he returned his face was animated.
+
+"Good news?" Penny asked eagerly.
+
+"Not exactly," Mr. Parker replied, sliding into a chair beside her and
+dropping his voice. "A message from Interceptor Headquarters. Monitoring
+machines have traced the outlaw radio station again. The broadcast
+finished about an hour ago."
+
+"And where was the station located this time, Dad?"
+
+"Seemingly at or near the lighthouse."
+
+"The lighthouse!" Penny exclaimed. She was so startled that her voice
+rose to a high pitch, attracting the attention of a passing bellboy.
+
+"Not so loud, Penny," her father warned. "The strange thing was that the
+broadcast seemed to come from a cave, the same as before, although the
+monitoring machines charted it as being close to the lighthouse."
+
+"The only one I know about near the Point is Crystal Cave," Penny said
+thoughtfully. "Dad, maybe the broadcast did come from the lighthouse!"
+
+"That's government property. Penny, and the man in charge is beyond
+suspicion. Furthermore, the deep, echo effect couldn't come from anywhere
+except a cave."
+
+"Unless it were a sound effect, Dad."
+
+"What's that?" Mr. Parker asked, startled. "I don't get you, Penny."
+
+"I mean, maybe the cave set-up is just a sound effect and nothing more.
+Only the other night I heard one in a radio play and it sounded as if the
+actors really were in a cave. Isn't it done by an echo chamber or
+something of the sort?"
+
+"That would be possible," Mr. Parker agreed. "At Interceptor Headquarters
+it was assumed that a mistake had been made in charting the location of
+the station."
+
+"Then the lighthouse hasn't been investigated?"
+
+"Not to my knowledge."
+
+"Well, it should be!" Penny exclaimed. "Louise and I were there today and
+we saw--"
+
+"Yes?" Mr. Parker questioned as she suddenly broke off.
+
+"We saw a lot that didn't look right," Penny finished, deciding not to
+bring Mrs. Deline's name into the discussion. "Mr. McCoy had visitors and
+while they were there he kept us locked up."
+
+"My word! Why didn't you report to the police?"
+
+"Well, we weren't entirely sure," Penny said lamely. "The door just
+closed and locked, and Mr. McCoy let on that it had a trick latch. Then
+he released us, but not until after the visitors had gone."
+
+"Did you see the persons?"
+
+"No, we only heard their voices. We weren't able to overhear any of the
+conversation."
+
+Without explaining what he intended to do, Mr. Parker again closed
+himself into a telephone booth. Not until he returned did he tell Penny
+that he had called Interceptor Headquarters and that Army men had been
+sent to the lighthouse to make a thorough check-up.
+
+"Now it's late," he said briskly, "and you're overdue for bed, Penny.
+Better fly up."
+
+"Aren't you coming?"
+
+"Not just now. I have a little unfinished business."
+
+Penny hesitated, unwilling to go to bed when she sensed adventure in the
+offing. As she groped in her mind for an excuse to remain, the doors at
+the front entrance to the hotel began to spin. Jerry came hurrying into
+the lobby. Seeing Penny and her father he made a straight line for them.
+
+"The code's been broken!" he announced, addressing Penny.
+
+"What did they learn, Jerry?" she asked eagerly.
+
+"It's just as you thought, Penny." Jerry dropped his bombshell. "Mrs.
+Deline definitely is an Enemy Agent. Apparently she was sent to Sunset
+Beach to aid that escaped prisoner I told you about!"
+
+
+
+
+ CHAPTER
+ 23
+ _NIGHT ADVENTURE_
+
+
+As Jerry made the startling announcement, Penny glanced anxiously at her
+father. In the excitement of the moment she had not thought how much of a
+shock it might be to him to learn that Mrs. Deline was an agent employed
+by a foreign country. To her astonishment, he looked neither surprised
+nor dismayed.
+
+"So you have the proof, Jerry!" Mr. Parker exclaimed. "That's fine! But
+what's all this about a code? How did you stumble onto it?"
+
+"No time for details now," Jerry answered tersely. "Penny turned the
+trick--she and Louise saw Mrs. Deline bury a package in the sand."
+
+"And Mrs. Deline brought that package from the lighthouse," Penny
+interposed eagerly. "Mr. McCoy must have given it to her."
+
+"What's the plan of action?" Mr. Parker demanded. "Army men already have
+gone to the lighthouse to search that place thoroughly."
+
+"Our job is to keep watch of the dune where the package was buried.
+Naturally we have no way of knowing what time anyone will show up there.
+It may be an all night wait."
+
+"I'll be with you in a minute," Mr. Parker declared. "Just as soon as I
+get an overcoat."
+
+He started toward the elevator, then came back to the group.
+
+"What about Mrs. Deline?" he asked. "She's here in the hotel. Went to her
+room only a few minutes ago."
+
+"She'll be placed under arrest," Jerry said. "Better call her on the
+telephone and get her down here. Don't let her suspect that you think
+anything is wrong."
+
+Mr. Parker vanished into the nearest telephone booth.
+
+"I can't understand it," Penny murmured to Jerry. "I was sure Dad was
+head over heels in love with Mrs. Deline. Why, it didn't even seem to
+ruffle him when he learned the truth about her."
+
+Jerry grinned. "Maybe," he drawled, "that was because he knew all the
+time."
+
+Penny was dumbfounded. "You mean--" she stammered, "You mean that Dad's
+been acting a part? Pretending to admire Mrs. Deline while actually he
+didn't?"
+
+"Something like that. You see, your Dad became interested in the outlaw
+radio station and the men who operate it. By making inquiries before he
+left Riverview, he obtained information that made him think Mrs. Deline
+might be involved in some way. He knew she never had been in China but
+spent many years in Japan. He learned also that instead of being a
+newspaper correspondent, she had carried on secret work for various
+governments."
+
+"Dad knew all that! And he never let on to me!"
+
+"He couldn't very well, Penny. If you had guessed the truth, you'd have
+given it away by your manner--no matter how much you tried to act
+natural."
+
+"What a little nit-wit I've been!"
+
+"You have not," Jerry denied warmly. "Anyone else would have acted the
+same. Without knowing it, you helped your father a lot. You turned up
+evidence he never could have obtained alone."
+
+"Where do you fit into the picture, Jerry? Did Dad send for you?"
+
+"You don't send for anyone in the Army," Jerry explained, grinning. "By
+pure luck I was assigned here on a special mission. Your father learned I
+was coming, so we united forces."
+
+"Then you've both known from the first about Mrs. Deline?"
+
+"We've had a dark brown suspicion, Penny. But no proof until tonight."
+
+Penny drew a deep breath. Before she could ask another question, her
+father came hurrying down the hotel corridor.
+
+"Mrs. Deline's not in her room!" he reported. "She doesn't answer."
+
+"She went upstairs only a few minutes ago," Penny recalled.
+
+"Yes, she did, but she's not there now."
+
+"Maybe she's asleep," Jerry said, "and failed to hear the 'phone. We'll
+have to check."
+
+Without explaining why the matter was urgent, Mr. Parker arranged with
+the desk clerk to have one of the hotel maids go to Mrs. Deline's room.
+While the trio waited in the upstairs corridor, the woman rapped several
+times on the bedroom door, and failing to get a response, unlocked it
+with her master key.
+
+"Mrs. Deline!" she called, softly at first, then in a louder voice.
+
+There was no answer.
+
+The maid then snapped on the light. "Why, there's no one here!" she
+cried. "The bed's not been slept in!"
+
+"That's what I was afraid of," muttered Mr. Parker.
+
+With Jerry and Penny, he entered the bedroom. Everything was in perfect
+order. However, Mrs. Deline's suitcase was gone and all her belongings
+had been removed from the closet.
+
+"She's skipped without paying her room rent!" the maid exclaimed. "I'll
+call the manager!"
+
+Penny was peering into the waste paper basket beside the desk.
+
+"Look!" she drew the attention of her father and Jerry. "Burned letters
+and papers!"
+
+Digging into the basket, she brought up several charred sheets of paper.
+They were unreadable and crumpled in her hand.
+
+"This was a bad break for us--Mrs. Deline getting away!" Jerry exclaimed
+in disgust. "Evidently her work at Sunset Beach is finished. She's moving
+on to another pasture."
+
+"But she can't be far away," Penny reasoned. "After all, we know when she
+came to her room."
+
+"There still may be a chance to nab her," Mr. Parker said. "We'll notify
+the police to guard all the roads and the airport. I'll report to Major
+Gregg too."
+
+Without awaiting the arrival of the hotel manager, the trio hastened to
+the lobby. There Jerry and Mr. Parker made several telephone calls.
+
+"Now let's be on our way up the beach," Jerry urged anxiously. "We've
+killed too much time as it is."
+
+Penny half expected that her father would refuse permission for her to go
+along. To her delight he merely said:
+
+"I suppose there's no keeping you here, Penny. Well, come with us. I
+guess you've earned the right by your good work."
+
+It was a dark night, warm but misty. No lights were showing outside the
+hotel, though far up the beach the powerful lighthouse beacon cut swathes
+across the black sea.
+
+"What's the plan?" Mr. Parker asked Jerry.
+
+"The entire coast for fifty miles is being watched. I thought just on a
+chance we might keep vigil at the place where Mrs. Deline buried the
+package of explosives. Someone may show up there. On the other hand,
+Penny tipped off the fact that she knew where the bundle was buried."
+
+"Mrs. Deline watched Louise and me through a spy glass," Penny recalled
+ruefully. "She knew we didn't find the package though."
+
+"That's our assignment anyhow," Jerry said. "To keep watch of that
+particular place until relieved by Army men."
+
+The Parker car was on the hotel lot close by. Getting it, the trio took
+the beach road but stopped some distance from the lighthouse. Not wishing
+the car to attract the attention of any passer-by, it was left parked on
+a private driveway. Jerry, Penny and her father then crossed the dunes
+afoot and proceeded up the beach until they came to their station.
+
+"Think this is the place?" Penny asked skeptically.
+
+"I know it is," Jerry replied. "Remember what I told you about taking
+observations? Let's see if the package is still here?"
+
+He began digging in one of the dunes. Almost at once he came upon the box
+of explosives.
+
+"Exactly as we left it," he reported, replacing the sand. "No one's been
+here."
+
+"I doubt anyone will come," Mr. Parker commented. "Probably afraid."
+
+High overhead and out of sight, Penny heard the drone of planes on
+coastal patrol. She stared up into the dark sky and then toward the sea.
+The tide was coming in and long rolling waves washed the beach, dashed
+themselves on the shoreline and retreated.
+
+"We'll have to get down out of sight," Jerry warned. "Mustn't be seen
+from the road or the ocean either one."
+
+"How about this spot?" Mr. Parker suggested, pointing to a hollow between
+two giant dunes.
+
+The place seemed exactly right, so the trio flattened themselves on the
+sand. Jerry looked at the luminous dial of his watch.
+
+"One fifteen," he announced. "No sign of activity."
+
+"And no sign of any soldiers," Mr. Parker added. "I hope that whoever is
+to take over here shows up before long."
+
+"I don't," Penny said, snuggling close between her father and Jerry. "I'm
+having fun!"
+
+"If anything should develop, it's apt to be serious business," Jerry
+warned. "I'm inclined to think that we tipped our hand and nothing will
+happen."
+
+An hour elapsed. During that time there was no sound save the roar of the
+restless sea. The warm sand made a comfortable couch, and despite her
+best intentions, Penny caught herself dozing. She had all she could do to
+keep awake.
+
+"What time is it now?" she presently asked.
+
+"Two thirty-five," Jerry answered. "It doesn't look as if there's to be
+any activity, but then the night's young."
+
+"The night may be, but I'm not," Mr. Parker grumbled, shifting into a
+more comfortable position. "Wonder when our relief is to show up?"
+
+"Must be some mix up on orders. We're probably stuck here for the night."
+
+"In that case, Penny should return to the hotel."
+
+"Oh, no. Dad! Anyway, if I left now I might attract the attention of
+anyone watching this place."
+
+"You thought that one up!" her father chuckled. "Except for ourselves,
+there's no person within a quarter of a mile of this place."
+
+"You're wrong about that," murmured Jerry, stiffening to alert attention.
+
+"What's up, Jerry?" Mr. Parker said quickly. "You act as if you were
+seeing things!"
+
+"I am, Chief! Look to the right--between us and the lighthouse!"
+
+Mr. Parker and Penny gazed intently in the direction indicated.
+
+"Can't see a thing," Mr. Parker whispered. "Your eyes must be tricking
+you, Jerry."
+
+"Wait just a minute."
+
+Even as Jerry spoke, a shadowy figure emerged from the mists. The man
+came swiftly down the beach, making no sound as he walked. When he was
+very close, the revolving beacon of the lighthouse singled him out for a
+fleeting instant. Brief as was the moment of illumination, Penny
+recognized the man.
+
+"George Emory!" she whispered tensely. "What's he doing here?"
+
+
+
+
+ CHAPTER
+ 24
+ _OUT OF THE SEA_
+
+
+The answer to Penny's whispered question soon became obvious. George
+Emory looked carefully about the windswept beach. The three tense
+watchers thought that he might approach the dune where they lay hidden,
+but he did not.
+
+Instead, the man paused while several yards away and gazed toward the
+sea. A moment he stood thus, silhouetted against the sky. Then using a
+glowing flashlight, he began making wide sweeps with his arm.
+
+"A signal!" Jerry whispered. "He's trying to attract the attention of a
+boat out at sea!"
+
+"Shall we go for him?" asked Mr. Parker.
+
+"Wait!" Jerry advised. "He's not the only one we're after. We're stalking
+bigger game."
+
+At intervals for the next fifteen minutes, George Emory repeated the
+flashlight signals. Then he turned off the light and waited.
+
+Anxiously, Jerry, Penny and Mr. Parker kept their faces turned to the
+sea. They sensed that the hour of action was at hand, and it worried them
+that Army men had failed to arrive.
+
+"Look, Dad!" Penny suddenly whispered. She had glimpsed far from shore a
+long shadowy object which easily could be a boat. No lights were showing
+nor had she heard any sound.
+
+"I don't see a thing," Mr. Parker whispered back. "Yes! Now I do! Jove!
+It looks like a submarine that's surfaced. I can make out the conning
+tower!"
+
+"But why would it dare come here?" Penny speculated. "Won't it be
+detected by the patrol planes?"
+
+"Tonight's a bad night," Jerry pointed out. "Besides, the shore is so
+indented at this point of coast that perfect protection is almost
+impossible. They're sending a boat, that's sure!"
+
+A small craft had been launched from the wave-washed deck of the
+submarine. Manned by two men who rowed with muffled oars, it slowly
+approached the shore. When it was very close the watchers behind the sand
+dune saw by its grotesque sausage shape that it was a large, rubber boat.
+Like a gray ghost it slid over the water.
+
+Mr. Parker gripped Penny's hand in an encouraging squeeze.
+
+"Wish you were safe at the hotel," he whispered. "I was a fool to let you
+come."
+
+Penny's heart pounded but she shook her head vigorously. Not for anything
+would she have missed the adventure. However, she was cool headed enough
+to realize that the situation was not shaping up well for her father and
+Jerry.
+
+There were two men visible in the rubber boat, unquestionably armed. Then
+George Emory must be reckoned with and the arrival of others might be
+expected at any moment. Jerry carried a revolver but her father had no
+weapon. Already it was too late for any member of the trio to safely go
+for help.
+
+"That sub may intend to land Secret Agents here," Jerry speculated. "But
+from the code message we deciphered, it's more likely they plan to take
+aboard one or more passengers."
+
+"Perhaps that escaped flier," Penny supplied.
+
+"He's a valuable man to them. Well worth the risk they're taking to try
+to rescue him."
+
+"If passengers are to go aboard, where are they?" Penny whispered.
+"There's no one here but George Emory."
+
+"We must wait and watch. We'll soon see enough or I miss my guess."
+
+The rubber boat had reached the surf and was being churned by the waves.
+Two men in full military uniform, leaped out and guided the boat to the
+beach. George Emory waded out to meet them. Shaking the hand of each, he
+spoke rapidly in German. Though Mr. Parker understood the language, he
+was unable to catch a word.
+
+Tensely, the trio waited and watched. At any moment they feared that the
+men from the submarine might seek the cache of explosives hidden not far
+away. Soberly Jerry and Mr. Parker considered trying to reach the box in
+the sand. To do so they must cross an open, unprotected span of beach
+with every likelihood of being seen.
+
+"Let's wait and see what happens," Mr. Parker advised. "We shouldn't risk
+calling attention to ourselves."
+
+George Emory and his two companions obviously were awaiting someone.
+Nervously they paced the beach. Several times Mr. Emory looked at his
+watch. Then from far down the road came the sound of a car traveling at
+high speed. Tires screamed in protest as the auto came to a sudden halt
+on the paved road back from the beach.
+
+"That's why they've waited!" Jerry whispered.
+
+Barely a minute elapsed before two figures were seen coming swiftly from
+the direction of the road. A man and a woman crawled through the bushes,
+under the fence, and walked hurriedly across deep sand to the beach.
+
+"Mrs. Deline!" Penny identified the woman. "The man with her is the same
+fellow who stole food from our camp!"
+
+"I'd know his face from photographs I've seen," contributed Jerry. "He's
+Oscar Kleinbrock, escaped German prisoner. The man I was sent here to
+trace!"
+
+Mrs. Deline and her companion reached the group of men who awaited them.
+
+"You are five minutes late," George Emory reproved.
+
+"Can we help it?" Mrs. Deline snapped. "We're lucky to be here at all. Do
+you know that the road is being watched?"
+
+"By whom?"
+
+"Army men. We were nearly stopped but were able to turn off into the
+thicket and wait."
+
+"Then there's no time to waste in talk," George Emory said curtly.
+Turning, he spoke to the German flier in his own language.
+
+"He's telling him to get aboard the rubber boat," Mr. Parker interpreted
+tensely. "Now they're saying goodbye to Emory and Mrs. Deline."
+
+"Somehow we must hold them all here!" Jerry whispered grimly.
+
+"It's two against five. And they're armed."
+
+Mr. Parker and Jerry looked at each other, fully realizing how slim was
+their chance of success. They were not thinking of themselves but of
+Penny and what could happen to her if they failed. Mr. Parker touched her
+arm.
+
+"Penny," he whispered. "Slip away in the darkness and make a dash for the
+hotel. Jerry and I will try to hold them until help comes. Just keep low
+as you run or those fiends may take a pot-shot at you." Penny would not
+desert her father and Jerry. Stubbornly, she shook her head.
+
+"We want to know that you are safe," Jerry urged. "Please go while you
+still have a chance. You can help us most by bringing help."
+
+Penny's determination to remain, weakened. Yet reason told her she never
+could reach the hotel and return with help in time to do any good. It
+dawned upon her that Jerry was only saying what he did to get her safely
+away.
+
+"If only we had the box of explosives!" she whispered. "With it we might
+have a chance against those men!"
+
+"It's too late to dig up the box now," said Jerry. "We probably couldn't
+find it without a light. And the noise we'd make--"
+
+"Let me try," Penny interrupted.
+
+"All right, see if you can get your hands on the box," her father agreed
+suddenly. "Slip back of the dune, and then circle. Don't try to cross the
+beach. Be careful! Remember the least sound will bring a hail of
+bullets."
+
+Penny nodded and slipped away into the darkness, crawling on hands and
+knees. Barely had she left the shelter of the big sand dune than she
+heard two shots fired in quick succession.
+
+"Those came from Jerry's revolver!" she thought. "Oh, it was a trick to
+get me safely away! Now he and Dad are in for fireworks!"
+
+Raising her head above the protecting sand dune, Penny saw why Jerry had
+fired. The rubber boat was being launched. To delay the attack would mean
+that the entire party might escape.
+
+"They'll all get away!" Penny thought in dismay. "How can Jerry and Dad
+hold them single handed?"
+
+George Emory returned Jerry's fire with deadly aim. The bullets bit into
+the dune, throwing up little geysers of sand.
+
+"Launch the boat!" he shouted savagely to the men from the submarine.
+"Get away while you can! Be quick!"
+
+Jerry and Mr. Parker were determined that the party should not escape. As
+the men sought to launch the rubber boat, they made a concerted rush for
+the German flier who was to be taken aboard the waiting submarine. Caught
+by surprise, he went down beneath their blows.
+
+Fearful of hitting his own man, George Emory dared not fire again.
+Instead, he and the crewmen of the submarine fell upon Jerry and Mr.
+Parker. In the melee, one person could not be distinguished from another.
+
+"Fools! Fools!" cried Mrs. Deline as she watched the fierce, uneven
+struggle. "There is no time to be lost!"
+
+Jerry and Mr. Parker were putting up the fight of their lives, but they
+were no match for four able bodied, trained men. Penny, desperate with
+anxiety, saw that the struggle could end only in one way--disaster for
+Jerry and her father.
+
+"If I had that box of explosives maybe I could help them!" flashed
+through her mind.
+
+Rolling over a dune, she ran to the place near the fence where she
+thought the cache was buried. Frantically she clawed and dug at the sand.
+She could not find the box.
+
+"It must be here!" she told herself desperately. "Or was it hidden in the
+next dune?"
+
+She tried another place slightly to the right. As she dug, she heard a
+sound behind her. Turning swiftly, she saw Mrs. Deline starting across
+the beach toward her.
+
+"Oh, no, you don't!" the woman shouted.
+
+Penny's hand encountered something hard and firm. The box of explosives!
+Digging wildly, she lifted it from the bed of sand and sprang to her
+feet. Her fingers closed upon one of the hand grenades.
+
+"Get back!" she ordered Mrs. Deline, balancing herself as if to throw.
+
+The woman stopped short, then retreated a few steps. But only for a
+moment was she frightened.
+
+"Why, you infant, you couldn't throw a grenade!" she jeered. "You don't
+know how. Besides, you haven't the nerve!"
+
+"Get back!" Penny ordered again. "I warn you."
+
+Mrs. Deline laughed scornfully and came on.
+
+Even the thought of throwing a hand grenade terrified Penny. She knew
+that she could not deliberately harm Mrs. Deline or even the men who were
+mercilessly beating her father and Jerry. Yet she had to do something.
+
+"Maybe I can destroy the rubber boat!" she thought. "It's far enough away
+so that no one should be hurt by the explosion."
+
+Whirling away from Mrs. Deline, Penny faced the sea. Fixing her eyes on
+her target, the rubber boat at the water's edge, she hurled the grenade.
+
+"Idiot!" cried Mrs. Deline, flinging herself flat on the sand to protect
+her face from flying fragments.
+
+Penny did likewise. The grenade dropped with a thud on the sand beside
+the rubber boat. Her aim had been perfect. But there was no explosion.
+Belatedly, Penny realized that she had forgotten to pull the safety pin.
+
+Mrs. Deline kept her face buried beneath her arms and did not yet know
+what had happened. Sick with the knowledge that she had failed, Penny was
+desperate. Her father and Jerry were being cruelly beaten by their
+opponents. In another minute they would be overpowered and the Germans
+would escape to the waiting submarine.
+
+"I can't let them get away!" Penny whispered. "I must do something!"
+
+Remembering the pencil bombs, she groped in the cardboard box for them.
+They were not there. Instead, her fingers closed upon the sharp bladed
+knife.
+
+"I'll slash the rubber boat!" she thought. "I'll try to make a hole in
+it!"
+
+Before Mrs. Deline realized what the girl was about, Penny darted down
+the beach. The men from the submarine did not see her. Reaching the
+rubber boat, she leaped into it. Working with desperate haste, she jabbed
+the knife through the bottom. The material was tough and it took all of
+her strength to make a long jagged gash. Water seeped in, slowly at
+first, then faster.
+
+"I've done it!" Penny thought jubilantly. "I've done it!"
+
+Her triumph was fleeting. The next instant the girl was struck a hard
+stunning blow from behind. As she collapsed in a limp little heap on the
+sand, she dimly saw the cruel, angry face of Mrs. Deline. Then all went
+black and she knew no more.
+
+
+
+
+ CHAPTER
+ 25
+ _A SCOOP FOR UNCLE SAM_
+
+
+Penny opened her eyes and wondered where she was. For a moment she could
+remember nothing of what had transpired. Gradually, she realized that she
+was lying down, her head pillowed in someone's lap. She seemed to be in a
+fast-moving motor boat for she could hear the wash of waves against the
+craft. In panic she decided that she must be a prisoner enroute to the
+German submarine. She struggled to sit up.
+
+"Easy there, partner," said a soothing voice.
+
+Penny twisted sideways to look at the speaker. "Jerry!" she whispered.
+
+"You're all right," he said, pressing her gently back. "We'll get you to
+a doctor in a few minutes."
+
+"A doctor, my eye!" Penny protested with spirit.
+
+"That was a nasty blow Mrs. Deline gave you on the head," contributed
+another voice.
+
+Penny turned again and saw her father. His shirt was half torn off and
+there was a long gash on his cheek.
+
+"Dad, you're hurt!"
+
+"Nothing but a few scratches, Penny. Jerry took worse punishment than I
+did. But you should see the other fellows!"
+
+"What happened?" Penny asked. "Where am I anyhow?"
+
+"In a patrol boat bound for the hotel."
+
+"But what happened on the beach? The last I remember was when I tried to
+slash the rubber boat."
+
+"You not only tried, you did!" chuckled Jerry. "Mrs. Deline struck you on
+the head with something--maybe a rock--and you went down for the count.
+About that time, some of the Army boys arrived. Mrs. Deline and her crowd
+tried to make a get-away, but the boat couldn't be launched."
+
+"Then what happened?" Penny demanded as Jerry paused for breath.
+
+"The two members of the sub crew tried to swim. They were picked up by a
+patrol boat that had been drawn to the locality by the gun fire."
+
+"And Mrs. Deline?"
+
+"She and her pal Emory, together with the escaped flier, struck off
+across the sand dunes."
+
+"They didn't get away?"
+
+"Not on your life. They reached the road and there found a nice reception
+awaiting them! Right now the three are lodged at Headquarters."
+
+Penny took a deep breath. Her head was throbbing but she scarcely felt
+the pain.
+
+"What about Jim McCoy at the lighthouse?" she inquired.
+
+"He was taken into custody earlier in the evening. A portable
+broadcasting outfit was found on the premises."
+
+"Then Mr. McCoy really was the man responsible for those mysterious
+broadcasts--the Voice from the Cave?"
+
+"No doubt he had helpers," Mr. Parker contributed. "We expect to track
+down most of the ring now that the leaders have been captured. At any
+rate, we've put an end to the broadcasts. Your other theory was right
+too, Penny."
+
+"What theory, Dad?"
+
+"That the cave effect was produced by an echo chamber."
+
+"Then no broadcast ever originated in a cave?"
+
+"Probably not. We know McCoy shifted locations frequently. Tonight was
+the first time he ever dared broadcast from the lighthouse."
+
+"And what of the old beachcomber, Jake Skagway?"
+
+"Just a beachcomber," Jerry answered. "He had no connection with Emory or
+Mrs. Deline."
+
+Penny lay perfectly still for a few minutes, gazing up at the dark sky. A
+few stars pricked the black canopy above her, and now and then a quarter
+moon peeped from behind a cloud screen.
+
+"How did I get aboard this boat?" she presently inquired.
+
+"Another patrol boat came by," Jerry explained. "In fact, after all the
+fireworks, just about everyone in Sunset Beach arrived on the scene. We
+wanted to get you to a doctor so we took the first transportation that
+offered."
+
+"Almost there now too," added Mr. Parker.
+
+Penny sat up. The shore was dark but she could dimly see the dark Crystal
+Inn hotel.
+
+"I don't need a doctor," she laughed. "I'm feeling better every minute.
+My, won't Louise be green with envy when she learns what she missed!"
+
+"I'd say she was lucky," Mr. Parker corrected. "Penny, you don't seem to
+realize what a narrow escape we all had."
+
+"That's right," added Jerry, "those men were desperate, and they'd have
+stopped at nothing. I guess we owe our lives to you, Penny."
+
+Penny loved the praise. Nevertheless, she replied with a show of modesty:
+
+"Oh, I didn't do a thing, Jerry. As a matter of record, I nearly messed
+up the show. When I threw that hand grenade I forgot to pull the safety
+pin."
+
+"I'm glad you did," chuckled Jerry. "If it had exploded, we might not be
+here now."
+
+Penny sat very still, thinking over what had happened. Events were a bit
+hazy in her mind and many questions remained unanswered.
+
+"The submarine?" she asked after a moment.
+
+"Sunk," Jerry replied. "One of our patrol planes scored a direct hit."
+
+"I guess that brings me up to date," Penny sighed, "There's only one
+thing that bothers me."
+
+"What's that?" inquired her father.
+
+"Did you know who Mrs. Deline was when you invited her to come with us to
+Sunset Beach?"
+
+"No, but I had a healthy suspicion that she might be working against our
+country, Penny. I first met Mrs. Deline at the Club. However, she was
+rather transparent in making a play for my attention. In checking up I
+discovered that she never had been in China and never had written a
+newspaper story in her life. When she practically invited herself to ride
+with us to Sunset Beach, I thought I'd try to find out more about her
+little game."
+
+"I acted so silly about everything," Penny acknowledged, deeply ashamed.
+"I'm sorry, Dad."
+
+"You needn't be, Penny. At times you were rude to Mrs. Deline which was
+wrong. But your actions served a good purpose by keeping the woman so
+diverted that she never was on her guard."
+
+Shore was very close. As the powerful engines of the motor boat became
+muted, Penny said wistfully:
+
+"Now that your work is done here, Jerry, I suppose you'll be winging off
+to some far corner of the country."
+
+"Not for a few days at least," he reassured her. "I'm expecting a
+furlough and I'll spend it right here at Sunset Beach. We'll cram those
+days full of fun, Penny. We'll swim and golf and dance. We'll make every
+minute count."
+
+The boat grated gently against the dock and a sailor leaped out to make
+the craft fast. Mr. Parker and Jerry helped Penny ashore. Though she
+tried to stand steady upon her feet, the boards rocked beneath her.
+
+"Hook on," invited Jerry, offering an arm.
+
+Mr. Parker supported her on the other side, and thus they walked slowly
+toward the hotel.
+
+"The Three Musketeers!" chuckled the editor. "'One for all, and all for
+one.'"
+
+"We do make a trio," agreed Penny. "Tonight it seems just as it did when
+we were together in Riverview working on a big news story. There's one
+difference though."
+
+"What's that?" asked Jerry.
+
+"Tonight we were actors in a little drama that should be page one on any
+newspaper. Yet neither of you news hawks so much as spoke of trying to
+get a scoop for the _Riverview Star_."
+
+"Good reason," rumbled Mr. Parker. "The story of what happened tonight
+may never be published."
+
+"I understand, Dad. If the news were printed now it might give valuable
+information to the enemy."
+
+Penny paused to catch her breath. With Jerry and her father still
+supporting her, she turned to face the restless sea. The patrol boat had
+slipped away into the darkness. Far up shore, unmindful that her
+faithless master had gone, the bright beacon from the lighthouse swept
+the water at regular intervals. Nothing seemed changed.
+
+"Curtain going down on one of the best adventures of my life," Penny said
+softly. "Who cares that the _Riverview Star_ missed the story? Why, this
+was an A-1 scoop for Uncle Sam!"
+
+
+
+
+ Transcriber's Notes
+
+
+--Replaced the list of books in the series by the complete list, as in
+ the final book, "The Cry at Midnight".
+
+--Silently corrected a handful of palpable typos.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be

+International donations are gratefully accepted, but we cannot make

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
