Just then Tom's keen eyes spotted a slip of paper tucked among the guns. He pulled it out. His heart gave a leap of excitement as he saw two words written on the paper--_Samson Narko!_ Hiding his amazement, Tom read the name aloud and added casually, "What's this? The make of one of the guns?" "Uh, yeah--that's right," the man replied. Without comment, Tom climbed out of the subcellar. As he bent down to drop the trap door, Tom flashed the officer a signal. Instantly the trooper grabbed Latty. "Hey! Why the rough stuff?" the prisoner exclaimed. Then, as he realized the officer was about to handcuff him, the man's face turned pasty white. He pulled free from the trooper's grasp and bolted toward the stairway. His nephew stood as if paralyzed at the sudden turn of events. [Illustration (Tom finds Latty's store of weapons)] Latty's attempt at flight was hopeless. Tom quickly brought him down with a flying tackle. Later, after Latty had been manacled, Tom helped him up. "In case you don't know it," the young inventory said coldly, "your friend Narko is in jail, so you may as well talk. What's the pitch?" Latty was trembling and still pale. "I--I d-didn't know there'd be any trouble with the cops or I'd never have done it," he quavered. "Narko offered me some dough to hide the guns. I needed money, so I took him up. That's all there was to it." "How long have you known this Narko?" Tom asked. "I met him a few days ago in a restaurant. Believe me, I'd never laid eyes on him before. And I wish I never had!" Latty added bitterly. The man's story had a ring of truth. "All right, Officer, let's take him in," Tom said. To the still-astounded Fred, he added, "We're sorry about this." Two hours later Tom and Bud sat in Chief Slater's office at Shopton police headquarters. Captain Rock and the Shopton fire chief were also on hand. "We've had troopers, detectives, and fire inspectors swarming all over Latty's place," Captain Rock reported. "They examined his house, the garage, two sheds out back, and every inch of the grounds. But there's no indication of any place where a bomb might have been planted to cause an underground explosion in Shopton." The fire chief nodded confirmation. "So that clue peters out," he said. With the waning of daylight, the other groups had finally abandoned their search of the Shopton area without turning up any information. "I'll notify the FBI immediately," Chief Slater said. Nevertheless, he promised that his men would continue their efforts the next day. "Even if we find nothing more, that arms cache was worth all the trouble," Slater added. "The country owes you a vote of thanks, Tom. A bunch of enemy agents could have hurt a lot of people with an arsenal like that!" "That's for sure," Captain Rock agreed. "It was a good day's haul, Tom."
