Phil gazed reflectively at the row of unfamiliar instruments covering half the table beside her. The "camera" which had taken an imprint of the Geest gun in Aunt Beulah's living room went with that equipment and had become an interior section of the largest of the instruments. "What do you call it?" he asked.

Celia looked irritated. Jackson laughed, said, "Why not tell him? Phil's feeling like we do—this is the last chance to look everything over, make sure nobody's slipped up, that nothing can go wrong. Right, Phil?"

Phil nodded. "Something like that."

Celia chewed her lip. "All right," she said. "It doesn't matter, I suppose—compared with the other." She tapped one of the instruments. "The set's called a duplicator. This one's around sixty years old. They're classified as a forgery device, and it's decidedly illegal for a private person to build one, own one, or use one."

"Why that?"

"Because forgery is ordinarily all they're good for. Frank was one of the best of the boys in that line before he found he'd been put on an outtransfer list."

Phil frowned. "But if it can duplicate any manufactured object—"

"It can. At an average expense around fifty times higher than it would take to make an ordinary reproduction without it. A duplicator's no use unless you want a reproduction that's absolutely indistinguishable from the model."

"I see." Phil was silent a moment. "After sixty years—"

"Don't worry, Phil," Jackson said. "It's in perfect working condition. We checked that on a number of samples."
