Dzhackoon nodded. "For a moment, it appeared you were disinclined to stop. I'm glad you decided to be reasonable." help to you." "Help how? If you've got ideas of bilking me...." The red eyes bored "Damned busybodies! Sensation-mongers! If it wasn't for the press, I'd have no concern for my paintings today!" "By the saints, he's right," Kelly exclaimed. "Maybe we ought to have a man in that vault." "Another idiotic scheme to waste my money," Snithian snapped. "I've made you responsible for security here, Kelly! Let's have no more "Never mind that," Kelly said, escorting Dan along the corridor. He Dan looked around at the gray walls, with shelves stacked to the low liverwurst, cheese and beer. He opened a loaf of bread, built up a well-filled sandwich, keyed open a can of beer. It wasn't fancy, but it would do. Phase one of the plan had gone off without a hitch. Basically, his idea was simple. Art collections had been disappearing from closely guarded galleries and homes all over the world. It was obvious that no one could enter a locked vault, remove a stack of large who hadn't entered in the usual way. Theory failed at that point that left the experimental method. The such a target, the thieves were bound to show up. If Dan sat in the vault—day and night—waiting—he would see for himself how they operated. He finished his sandwich, went to the shelves and pulled down one of the brown-paper bundles. Loosening the string binding the package, he slid a painting into view. It was a gaily colored view of an open-air at a table. He seemed to remember reading something about it in a magazine. It was a cheerful scene Dan liked it. Still, it hardly of the filaments died, leaving only a faint illumination from the night-light over the door. When the thieves arrived, it might give him a momentary advantage if his eyes were adjusted to the dark. He groped his way to the bunk. So far, so good, he reflected, stretching out. When they showed up, he'd have to handle everything just right. If he scared them off there'd be no second chance. He would have lost his crack at—whatever his discovery might mean to him. But he was ready. Let them come. Eight hours, three sandwiches and six beers later, Dan roused suddenly from a light doze and sat up on the cot. Between him and the crowded was dry. This was the moment he'd been planning for, but now that it was here— Never mind. He took a deep breath, ran over the speeches he had prepared for the occasion: Greeting, visitors from the Future.... No good it lacked spontaneity. The men were rising, their backs to Dan, stepping out of the skeletal frame. In the dim light it now looked ordinary enough: Two men in gray coveralls, one slender and table, twiddled a knob. A warm light sprang up. The visitors looked at the stacked shelves. "Looks like the old boy's been doing all right," the shorter man said. in the cage, stopped dead as he caught sight of Dan. The painting "Paintings? Look, it was all a mistake. Like, we figured this was the gent's room—" than the likes of you to out-fox an old-timer like Eddie Kelly." "Perhaps you were right, Manny," Fiorello said. "Complications are arising. We'd best depart with all deliberate haste." He edged toward the cage. The balding man snatched suddenly for the gun. Dan wrestled with him. Kelly capered before the cage, fluorescing in the blue-violet. Dan swallowed hard and nudged a second lever. The cage sank like an elevator into the floor, vivid blue washing up its sides. Hastily he reversed the control. Operating a time machine was tricky business. One little slip, and the Slane molecules would be squeezing in among brick and mortar particles.... But this was no time to be cautious. Things hadn't turned out just the way he'd planned, but after all, this was what he'd wanted—in a way. The time machine was his to command. And if he gave up now and crawled of the past decade on him. It couldn't be too hard. He'd take it slowly, figure out the controls.... Dan took a deep breath and tried another lever. The cage rose gently, much as a minute into the past or future. He looked over the controls. There should be one labeled "Forward" something thrown together hastily from common materials. Still, it worked. So far he had only found the controls for maneuvering in the usual three dimensions, but the time switch was bound to be here somewhere.... another second she would see him, and give the alarm—and Dan needed a few moments of peace and quiet in which to figure out the controls. out on the terrace, lit a cigarette, paused, started to turn his face up— With a sudden lurch that threw Dan against the steel bars, the Dan sank to the floor of the cage, breathing hard. There was a loud With a lunge, Dan scrambled out of the cage. He stood looking around at "The carrier returns here automatically when the charge drops below a critical value," the voice said. "A necessary measure to discourage "I just wanted—I mean, after I figured out—that is, the police ... I went for help," Dan finished lamely. "Help? Out of the picture, unfortunately. One must maintain one's to catch a brown eye upon him. Only one. The other seemed to be busily at work studying the ceiling. "I hope," the voice said, "that you ain't harboring no reactionary "That reminds me," Dan said. "I have to be running along now." He sidled toward the door. "I pride myself on my command of the local idiom, yet I confess the implied concept snows me." The nine-fingered hands folded on the desk. The brown eyes blinked in agitated alternation. "Apparently I've loused up my investigation of the local cultural background. I had no idea you were capable of that sort of thing." The immense head leaned back, the wide mouth opening and closing rapidly. "And to think I've been spinning my wheels collecting primitive 2-D art!" much too far to jump. Maybe he could reach the machine and try a getaway— "I hope you're not thinking of leaving suddenly," the beachball said, smoothly toward the flat roof Dan indicated. "Better let me take over now," Dan suggested. "I want to be sure to get us to the right place." grew even fainter. "Best we remain unnoticed," he explained. The cage descended steadily. Dan peered out, searching for identifying landmarks. He leveled off at the second floor, cruised along a barely visible corridor. Blote's eyes rolled, studying the small chambers III Dan slumped back against the seat with a sigh. Now that he was in the clear, he would have to decide on his next move—fast. There was no telling what other resources Blote might have. He would have to hide landscape of trees and houses. Dan covered his ears against the The noise seemed to lessen, descending the scale. Dan slowed, brought Dan stepped from the carrier and looked around. Whatever the noise hadn't it gone into action earlier? Dan took a deep breath. Sound or no sound, he would have to get back into the carrier and transfer it to a secluded spot where he could study it at leisure. He stepped back in, reached for the controls— There was a sudden chill in the air. The bright surface of the dials like a flashbulb exploding. Dan stared from the seat at an iridescent rectangle
