Their key agent in America was the man who had posed over the phone as Lester Morris and masterminded the other attempts to kidnap Tom. He had also taken the amulet bracelet from Ames's jacket in a restaurant. Mirov himself had been given the bracelet after his jail break. Pulling back the sleeve of his frogman suit, he displayed it with a momentary smirk of pride. "I even got inside the grounds of Swift Enterprises and stole a plane that same night," Mirov boasted. Tom was startled. "How did you manage that?" "Very simple. I thumbed a ride with one of your trusted workers on the late shift and showed him the amulet to identify myself as a Swift employee. The guard at the gate was fooled the same way." Tom nodded thoughtfully. "They were instructed to look for a man trying to sneak past alone. Seeing you in the same car with a known employee, he probably assumed you were all right." Mirov was allowed to change into dry clothes, then his hands were bound behind his back. When the water cleared, Tom and Bud ventured outside again. First they headed for Bud's jetmarine to reassure his crew. Here they learned that the mystery submarine had vanished. "Good riddance!" Bud exclaimed jubilantly. "They probably didn't even realize you had found the missile!" "_Had found_ is right--past tense," Tom said wryly. "It's no doubt buried again. But at least we have the right spot." They emerged from the jetmarine and headed back toward the site. As they glided astern of the _Sea Hound_, Tom uttered a cry over his suit mike. "_Bud! There it is!_" Both boys darted ahead at increased speed, and Tom played his flashlight beam over the precious treasure. Instead of burying the missile deeper, the grenade explosion had uncovered the entire nose cone and part of the section behind it! "Sizzlin' squids! What a break!" Bud whooped. The boys jetted back to the _Sea Hound_ to announce the good news. Zimby and two other crewmen were dispatched in hydrolungs to inform the other ships. Tom requested them to remain submerged and guard the site. Twenty minutes later the _Sea Hound_ was zooming up to the surface. Tom hoisted the craft's aerial and radioed word to his father, who was overjoyed. Mr. Swift, in turn, had news--that the rebels' key man and Len Unger had been seized by the FBI. Tom's next call was to Admiral Walter. "Tom, this is wonderful news!" the admiral exclaimed. "I'll have our Navy ships routed back there immediately--and I intend to fly out myself as soon as I can board a plane!" As Tom waited for the task force to arrive, his thoughts turned to new inventions to tackle. But he could not anticipate what would happen to him in his _Triphibian Atomicar_. Within hours, the task force arrived at the site and recovery operations got under way. The missile was hoisted to the surface by cables attached to submarines, then hauled aboard the tender. Tom himself supervised the job of extracting the sealed data section.
