That was a tip-off. Watkins momentarily forgot his great loss. "They left, and in a minute, we were asleep. They must have pumped some sort of gas into the lab. Sleep gas." "Is there such a thing?" asked Cal. "An anesthetic vapor that would permeate such a large place so quickly?" "Is there such a thing as a four dimensional maze?" asked Adam shortly. Watkins grinned. He wasn't the only one who needed his morning coffee. Then he thought of his briefcase again. He tried to push the moving wall to one side; no go. He got mad again. "It's no good to them," he said. "What do they want with it?" "It couldn't have been so important that--" began Full. "Important?" Watkins was yelling now, and although he disliked raising his voice and making scenes, he did it now, with furious pleasure. "Cal, you never saw anything more important in your life than that case, and I don't care how many blue-ribboned cows you've gaped at!" "What was in it?" asked Villa. "Money, goddammit, money!" It didn't matter if his secret came out now. In this insane place, God knew where, the cautious habits of half a lifetime slid away. "The best haul I'd made this year. The contents of the safe of Roscoe & Bates, that's what was in it! Better than twenty-two thousand in good, green cash!" "The contents of a safe?" Calvin Full frowned. "You mean you were a messenger, taking it somewhere, and got on that roller coaster with--" Adam Pierce laughed abruptly. "No, he wasn't a messenger," he said. "He wasn't any messenger. He's a safe-cracker. Mr. Watkins, what good do you think it'd do you in here?" "We'll get back." "You're a safe-cracker?" asked Mrs. Full, her pale face lengthening with horror, disgust, and fear. "A criminal?" "In a manner of speaking, ma'am," said Tom Watkins, "I am." "I'll be hanged," said Summersby. "And you accused me of stealing your loot. I ought to butter you all over the wall." "You try it, you overgrown galoot. I didn't do a hitch in the Philippines for nothing." Watkins smoothed back his hair, which was dangling into his eyes. "Sure, I'm a safe man. Don't worry, Mrs. Full, that doesn't mean I'm a thug." She looked scared. "That's right," said Adam, still chuckling. "This boy's the aristocracy of crime. You don't have to worry about your purse. He only plays around with big stuff." Tom flipped him a grin. "I'll bet you even know why I was on the coaster." "Sure. You were hiding out." "That's it. If I kept out of sight till dark I was okay. They were out for me, because my touch is known; but who'd think of checking an amusement park?" He turned as Cal made a noise in his throat. The Vermonter was a study in outraged sensibilities. "You--you swine," he said, a typical Victorian hero facing the mustache-twisting villain. "You stole that money--" "My morals and your morals, Cal," said Watkins as genially as he could, "are probably divergent, but it doesn't make a whale of a difference now, does it?"
