Footprints Under the Window

by Franklin W. Dixon

  He cried out angrily, “Give me that shell! It’s mine!”

  To everyone’s astonishment, he snatched the shell from Callie’s grasp!

  CHAPTER X

  Discreet Intruder

  “IT’S my shell—I found it!” Callie protested. But at the unkempt stranger’s savage expression, she stepped back in fright.

  “She did find it,” Joe asserted firmly. “What’s the big idea, mister?”

  The man’s eyes gleamed suspiciously at the teen-agers. Gripping the shell tightly, he started down the slope.

  Frank blocked his path.

  “Just a minute,” he said evenly. “What right do you have to this shell? Who are you?”

  “I’m called Sandy,” the man said sullenly. He jammed the object into his pocket. “I found this shell earlier and put it here.”

  “That’s not likely,” Frank disagreed, pointing toward the incline. “Those footprints up there are too big to be yours. Besides, why would you have left the shell here?”

  As the others stepped closer, the man shifted uneasily, as if groping for an excuse.

  “Please,” Iola spoke up, “my friend Callie and I collect shells. There are lots of other pretty ones left on the beach.”

  Sandy shook his head stiffly. “No. I must take this to Mr.—” He broke off, then continued, “You see, I sell shells to get enough money so I can eat. It’s my only job.”

  So sudden was his change of manner that Callie relented. “All right, you may keep the shell.”

  She had scarcely finished speaking when the man marched quickly away. He soon disappeared around a bend in the beach.

  “You shouldn’t have given it to him, Call” Chet insisted. “He as much as admitted he was lying!”

  Callie sighed. “Well, he’s evidently very poor, and needs the shell more than I do. Maybe we can find another!”

  Both Frank and Joe were studying the circle of footprints. “They’re damp,” Frank observed. “What strikes me is the perfect pattern, as if to mark where that shell was.”

  Joe then noticed a jumbled series of prints leading toward the water. The brothers followed the trail down the slope. Here they diverged into two distinct sets of tracks—one coming and one going. Both ended at the water’s edge.

  “Let’s separate and see if there are more prints along the beach,” Frank suggested.

  The Hardys combed the surf in opposite directions. When they rejoined the others later, neither boy had spotted any further trace of footprints.

  “Whoever made the prints must have either swum a long distance,” Joe said, “or come ashore from a boat.”

  Chet glanced at the Hardys. “I’ll bet you two have some theory cooking,” he said.

  Frank nodded. “That beachcomber’s fishy story, these footprints—I’ll bet something important was inside that shell.”

  “A message?” Callie asked.

  “It’s a good guess,” Frank replied.

  Secretly he and Joe were wondering if the mysterious prints and shell had a connection with the Footprints plot! “Wild hunch,” Frank told himself. “But I’d like to know who’s buying that shell.”

  For the next hour the young people hunted shells, but found none like the beachcomber had taken. Frank and Joe scanned the area in vain for any further sign of the stranger.

  Suddenly Chet shouted, beckoning to the others. “Storm’s coming up fast!”

  The sky was rapidly filling with black clouds. Rumbles of thunder could be heard. Iola gathered the collection of shells into a large kerchief. By this time drops of rain had become a downpour.

  The girls and boys dashed to the car and clambered in. Torrents of rain drummed on the steaming roof as they rode homeward. Joe reminded Chet of his optimistic weather forecast.

  Chet, in back with Joe and Iola, asked innocently, “So what am I, a barometer?”

  After dropping Chet and the girls off, the Hardys stopped at the immigration office to inquire about Gomez. No trace of him or of the three thugs had been found.

  “We’ve been turning this town upside down,” Scott told them. “If the gang hasn’t left Bayport, it has certainly found good hideouts.”

  Back home, the Hardys determined to return to Barren Sands and watch for another possible “pickup” by the beachcomber.

  After supper an urgent phone call came from Mr. Morton. The realtor asked the brothers to hurry to the Voyager Travel Bureau. Frank and Joe lost no time in driving downtown.

  Mr. Morton quickly let them into the street-level office. He looked worried.

  “Frank and Joe! Glad to see you! Somebody has broken in here again!”

  “When did you find out?” Frank asked.

  “Just before I called you. We’d closed up, but I came back for some papers. I was just in time to spot a stocky, flat-nosed man dropping out the back window. I couldn’t catch him.”

  Joe whistled at the description. “Frank! Sounds like the fellow we chased at Micro-Eye—and tangled with in the boathouse!”

  Frank asked what had been taken. Mr. Morton led them into the back office, switched on a light, and looked around, perplexed.

  “That’s just it—nothing. Same as before.” The police, he added, had found no fingerprints.

  “Was anything disturbed tonight?” Frank asked.

  “Yes.” Mr. Morton pointed to a thin sheaf of papers on top of a desk. “Records of our travel customers this week. I found the papers flipped over when I returned from chasing the intruder.”

  Frank sat down and studied the booking list. It included destinations, tour plans, prices, and means of travel. Most of the clients were Bayport residents.

  “What use could these be to an outsider?” Joe wondered, peering over his brother’s shoulder.

  Mr. Morton sank wearly into a chair. “I can’t imagine. That’s why I called you boys.”

  Frank continued reading the list. Suddenly he pointed to an entry near the bottom:

  Mr. Raymond Martin. Cayenne. Jetliner.

  “Hmm.” Joe’s eyes narrowed. “It’s the only South American destination listed for tonight!”

  “Do you think this is significant?” Mr. Morton asked quickly.

  “Possibly,” Frank replied. He asked Chet’s father about Mr. Martin.

  “I don’t know him personally. I believe the arrangements were made by phone.” Mr. Morton sighed. “The Oak Hollow trouble and now this!”

  “It’s a puzzle,” Frank agreed. “I have an idea, but I’m going to let it simmer until we do some legwork.” He asked Mr. Morton to notify Micro-Eye Industries of the prowler he had seen.

  “Sure will. Thanks for your help, boys.”

  Outside, Joe started to ask Frank about his idea, but his brother rushed him into the car. “I’ll tell you on the way to the airport.”

  “The airport!”

  Frank slipped behind the wheel and headed west. “Raymond Martin,” he explained, “is scheduled to leave by plane tonight. We might be in time to get a look at him.”

  Joe snapped his fingers. “You figure the intruder was after something in particular—like Mr. Martin’s name?”

  “Right—and that could be an alias.”

  Frank recalled the luggage thefts Jack Wayne was to investigate. “This plane stops over in Cayenne. Martin could either be slated as a possible victim of the thieves—or in league with the spy ring!”

  The Hardys parked near the main terminal at Bayport Airport. Inside the spacious building, they quickly found the passenger gate for Flight 54.

  “Martin should come through here,” Frank whispered, checking his watch. “The plane takes off in ten minutes.”

  Frank asked the gate attendant if a Mr. Martin had yet boarded the plane. The man shook his head. “I doubt it. Nobody by that name has shown me a boarding pass. But he’d better hurry—plane’s readying for take-off.”

  The attendant agreed to nod to the Hardys if Martin appeared. Frank and Joe went to stand inconspicuously against a baggage locker
nearby and watched boarding passengers file through the gate. Beyond a steel-laced glass wall, landing planes blinked like huge fireflies.

  Both boys felt tense. Would they recognize Raymond Martin? Was he an ordinary traveler, or could his name be an alias for Gomez or any of the other elusive suspects?

  Five minutes passed. The jets of the silver Brazil-bound liner screamed to life.

  “No, you haven’t missed him,” the attendant assured the Hardys. “Mr. Martin’s the only passenger not aboard.”

  “It looks as if he’s not going to show,” Joe concluded, disappointed.

  “Maybe he spotted us here,” Frank said. “Quick! Let’s pretend to leave.”

  The boys hurried off through the crowd. Joe turned his head casually. The next second he grabbed Frank’s arm. “Look!”

  A middle-aged, well-dressed man was rushing toward the Flight 54 gate, trailing a white raincoat from his arm.

  “Wait!” he shouted. “Hold the plane!”

  The Hardys were close enough to see that the man’s face was completely unfamiliar. As the passenger darted through the gate, his coat hem caught on the end of the metal railing. The man snatched the coat free, but a large piece of lining was torn off and dropped to the floor.

  The man did not stop. He ran to the landing ramp and climbed into the jetliner. A minute later the huge craft taxied off and soon rose into the night sky. Frank and Joe stood at the gate staring in chagrin after the plane.

  “That was Mr. Martin, all right,” the attendant affirmed. “Too bad you boys didn’t get a chance to visit with him.”

  Frank retrieved the piece of bright plaid lining, and the brothers walked back across the terminal. “Well, I guess I led us on a wild-goose chase,” Frank apologized.

  But as he examined the torn material, he noticed a glossy, black edge protruding from a ripped seam.

  “Joe, look at this!”

  Frank pulled at the edge. A small roll of celluloid fell to the floor!

  CHAPTER XI

  A Secret Revealed

  FRANK stooped and picked up the celluloid coil from the floor of the air terminal.

  “Joe, it’s film!”

  The Hardy boys examined the torn patch from the stranger’s raincoat. A tiny pocket, now ripped, was visible in the plaid lining.

  “Pretty clever,” Joe murmured. “The film must have been sewn in to avoid detection.”

  “Something tells me we’d better take a good look at this film,” said Frank.

  The brothers hastened to a quiet corner of the terminal. Frank unfurled the strip of small film and held it up to the overhead lighting.

  “What does it show?” Joe asked excitedly.

  “It’s hard to make out.” Frank squinted up at the tiny frames. “Machinery of some sort—maybe a factory interior—wait! Jumping crickets, look at this!”

  Joe grabbed the bottom of the strip and inspected the frame near his brother’s thumb. It was an outdoor view showing a high, steel fence and two uniformed figures. Joe gasped.

  “The Micro-Eye plant!”

  “You bet it is—and taken from inside the fence!”

  Half-incredulous, the Hardys scrutinized the film’s other frames—close-ups of the complex and labeled diagrams.

  “Blueprints!” Joe whispered as Frank quickly wrapped the spool in the scrap of raincoat.

  The boys had no doubt of the importance of what they had come upon: chilling evidence of espionage at Bayport’s top-secret project!

  “But if Raymond Martin is a spy,” Joe wondered, “why didn’t he stop to pick up the torn piece?”

  “He may not have realized it contained the film. Come on! We’re going to get this to Mr. Dykeman pronto!”

  Frank and Joe surveyed the terminal. Satisfied that nobody had been watching them, they walked to an outside telephone booth where Frank contacted Roy Dykeman.

  He urgently related what had happened, but, as a precaution, omitted precise details of the film. The intelligence agent reacted immediately.

  “Stay right where you are,” he directed tersely.

  Minutes later, the Hardys were greeted by two plainclothesmen, who quickly identified themselves with credentials as Miller and Kyle. The boys followed the men out to the parking lot.

  Inside the agents’ sedan, the boys related what had happened. The men rapidly jotted down notes. When Frank turned over the film, both agents were impressed.

  “Great going, boys! Too bad Martin slipped by, but he’ll be watched when he lands. This evidence could shed light on the Footprints plot. Be careful! We’ll be in touch.”

  The sedan roared off, and the Hardys went to their car. Back home, Joe checked the Bayport telephone directory. A Raymond Martin was listed at a residential address. The brothers took turns dialing the number at intervals, but there was no answer. They found that Mr. Hardy’s criminal files had no record of the suspect.

  The brothers tumbled into bed, but neither fell asleep immediately. Speculations raced through their minds. Who was the mysterious Mr. Martin, now airborne to South America?

  The next morning after breakfast the Hardys had a phone call from Mr. Dykeman. He asked them to come at once to the photographic plant.

  Excitedly Frank and Joe dashed outside to their car and in twenty minutes drew up at the Micro-Eye gate. Agent Kyle, to whom they had given the film, looked in their window, then nodded to the guards.

  “Mr. Dykeman’s expecting these boys,” he said.

  The Hardys were waved through. They parked in the employees’ lot and were escorted by a guard to a second-floor office adjoining the main plant.

  Mr. Dykeman, looking tired, rose from his desk in the small, map-lined room. His expression was grave as Frank and Joe took seats.

  “What you two came upon at the airport last night is a major breakthrough for us,” the agent said. “But it’s also given us cause for serious concern.”

  “Then that film was taken by a spy?” Frank asked.

  “No question about it. This is proof of an internal security leak at Micro-Eye.”

  Joe told of the boys’ futile efforts to phone Raymond Martin’s home.

  Dykeman smiled. “It seems he is a highly respected insurance executive who was recently transferred to Bayport. He has no family.”

  “So he probably isn’t knowingly involved in the film business?” Frank queried.

  “We believe that’s the case,” replied Dykeman. “He is going to Cayenne supposedly on business. Of course, Martin could be a courier for the espionage ring in Bayport, told to wear the raincoat but not why.”

  “Which would mean,” Joe put in, “that the film was meant to be picked up in Cayenne.”

  “Yes.” Dykeman went on, “We’ve wired our people there to watch for Martin, and also, for anyone who tries to get his coat. We’re hoping the spies won’t learn of our recovering the film until after Martin’s arrival.”

  The Hardys were also told that no trace of Gomez or the other three men had as yet been uncovered. The intelligence officer walked to the window and looked across at a long brick building. He turned and smiled at the boys.

  “I imagine you’re curious about the nature of the Micro-Eye project.”

  Joe and his brother exchanged glances. “I guess we’d have to admit that!” Frank grinned.

  The agent nodded. “We’ve already had you cleared. You have a right to know the basics of the project, considering your involvement and cooperation in the Footprints case. And because your own lives stand in considerable danger.”

  Frank and Joe waited tensely.

  “In simple terms,” Dykeman continued, “Micro-Eye is building a powerful satellite camera.”

  The boys leaned forward, their interest doubly aroused. “How powerful?” Joe inquired.

  “One so strong in range and definition it will be capable of telescoping terrain from the highest altitudes. Even”—he chuckled—“a baby’s footprints on a gravel path.”

  “Wow!” Joe repress
ed a whistle. “A camera like that would have terrific military value! No wonder spies are after it.”

  Mr. Dykeman explained that after secret project drawings were found missing, the satellite camera’s completion had been delayed by “decoy” work undertaken at the plant.

  Dykeman held up the familiar spool of film. “Fortunately, whoever took these pictures fell for some phony blueprints. But we cannot delay the project any more. The government is pressing us.”

  Frank spoke up thoughtfully. “Since the code name of this spy ring is Footprints, maybe there is a link with the Huella Islands.”

  “Huella,” Joe repeated, then snapped his fingers. “You’re right. Huella is Spanish for ‘footprint’!”

  Mr. Dykeman and the boys studied a detailed map of South America. Like jagged footprints, the small Huella island group extended north off French Guiana.

  Since the dictator there is unfriendly to the United States, he may well be a party to the plot,” Joe suggested.

  “Perhaps,” Dykeman agreed. “We’ve discovered that there is great dissatisfaction among the people, even though Posada did away with the infamous prison colony on the island as a concession to them.”

  “Have you any idea who took the pictures?” Frank asked Mr. Dykeman.

  The agent motioned the Hardys to accompany him. He led them downstairs and across the yard some distance from the building.

  “To answer your question, Frank,” he said in a low tone, “we’re turning this place upside down for clues. There are several hundred employees, including engineers and technicians. We’re running a check on everyone. So far, no suspects. The outside concessions for food and laundry service are kept to restricted areas, and there are constant spot checks at the gate.”

  “How about the guards?” Joe inquired.

  “Thoroughly screened, and all trustworthy,” the agent declared. He added that the men’s posts were frequently shifted as a double check.

  “You think we could have a look around?” Frank asked, glancing over at the main plant.

  “I was just about to suggest that.” Mr. Dykeman fastened visitors’ badges to the boys’ lapels.

  “These will allow you the run of the place,” he said, smiling. “Stop back at my office if you come up with any hunches!”
