Malone tried to stop himself from beaming, but he couldn't. "Well, chief," he began, "I--"

"Vanishing boys," Burris muttered. "What are you going to do with them, Malone?"

"I was hoping you might have some kind of suggestion," Malone said.

"Me?"

"Well," Malone said, "I suppose I'll figure it out--when I catch them.

But I did want something from you, chief."

"Anything, Malone," Burris said. "Anything at all."

"I want you to get hold of Dr. O'Connor, out at Yucca Flats, if you can.

He's the best psionics man Westinghouse has right now, and I might need him."

"If you say so," Burris said doubtfully.

"Well," Malone said, "these kids are teleports. And maybe there's some way to stop a teleport. Give him a good, hard kick in the psi, for instance."

"In the what?"

"Never mind," Malone said savagely. "But if I'm going to get any information on what makes teleports tick, I'm going to have to get it from Dr. O'Connor--right?"

"Right," Burris said.

"So get in touch with Dr. O'Connor," Malone said.

"I'll have him call you," Burris said. "Meanwhile ... well, meanwhile just carry on, Malone. I've got every confidence in you."

"Thanks," Malone growled.

"If anybody can crack a case like this," Burris said, "it's you."

"I suppose it had better be," Malone said, and rang off.

Then he started to think. The notebook wasn't in his pockets. He checked every one, even the jacket pocket where he usually kept a handkerchief and nothing else. It wasn't anywhere on his person.

Had he left it in his room?

He thought about that for several minutes, and finally decided that he hadn't. He hadn't taken it out of his pocket, for one thing, and if it had fallen to the ground he couldn't have helped seeing it. Of course, he'd put his wallet, keys, change and other such items on the dresser, and then replaced them in his pockets when morning had come--but he could remember how they'd looked on the dresser.

The notebook hadn't been there among them.

Now that he came to think of it, when had he seen the notebook last?

He'd shown it to Lieutenant Lynch during the afternoon, and then he'd put it back in his pocket, and he hadn't looked for it again.

So it had to be somewhere in one of the bars he'd visited, or at the theater where he and Dorothy had seen "The Hot Seat."

Proud of himself for this careful and complete job of deduction, he strolled out and, giving Boyd and the Agent-in-Charge one small smile each, to remember him by, he went into the sunlight trying to decide which place to check first. He settled on the theater because it was most probable: after all, people were always losing things in theaters.

Besides, if he started at the theater, and found the notebook there, he could then go on to a bar to celebrate. If he found the notebook in a bar, he didn't much relish the idea of going on to an empty theater in the middle of the afternoon to celebrate getting the book back.

Shaking his head over this flimsy structure of logic, he headed down to "The Hot Seat." He banged on the lobby doors for a while without any good result, and finally leaned against one of the side doors, which opened. Malone fell through, recovered his balance and found himself facing an old, bewhiskered man with a dustpan, a broom and a surprised expression.

"I'm looking for a notebook," Malone said.

"Try a stationery store, youngster," the old man said. "I thought I'd heard 'em all, but--"

"No," Malone said. "You don't understand."

"I don't have to understand," the old man said. "That's what's so restful about this here job. I just got to sweep up. I don't have to understand nothing. Good-by."

"I'm looking for a notebook I lost here last night," Malone said desperately.

"Oh," the old man said. "Lost and Found. That's different. You come with me."

The old man led Malone in silence to a cave deep in the bowels of the theater, where he went behind a little desk, took up a pencil as if it were a club, held it poised over a sheet of grimy paper, and said: "Name?"

Malone said: "I just want to find a notebook."

"Got to give me your name, youngster," the old man said solemnly. "It's the rules here. After all."

Malone sighed: "Kenneth Malone," he said. "And my address is--"

The old man, fiercely scribbling, looked up. "Wait a minute, can't you?"

he said. "I ain't through 'Kenneth' yet." He wrote on, and finally said: "Address?"

"Statler Hilton Hotel," Malone said.

"In Manhattan?" the old man said.

"That's right," Malone said wearily.

"Ah," the old man said. "Tourist, ain't you? Tourists is always losing things. Once it was a big dog. Don't know yet how a dog got into this here theater. Had to feed it for four days before somebody showed up to claim it. Fierce-looking animal. Part bloodhound, part water spaniel."

Fascinated in spite of himself, Malone said: "That's impossible."

"Nothing's impossible," the old man said. "Work for a theater long enough and you find that out. Part bloodhound, I said, and part water spaniel. Should have seen that dog before you start talking about impossibilities. What a strange-looking beast. And then there was the time--"

"About the notebook," Malone said.

"Notebook?" the old man said.

"I lost a notebook," Malone said. "I was hoping that--"

"Description?" the old man said, and poised his pencil again.

Malone heaved a great sigh. "Black plastic," he said. "About so big." He made motions with his hands. "No names or initials on it. But the first page had my name written on it, along with Lieutenant Peter Lynch."
