"You mean it's impossible?"

"Yes!"

"That's just what I've been saying all along," Janice said triumphantly.

"Oh, stop that," Bob said. "I wish I could figure this out. No matter what country the ferra is from, it's bound to have an effect on the future. We can't have a paradox."

"Why not?" Janice asked, but at that moment the ferra appeared.

"The king has agreed," the ferra said. "Will this pay for what I've taken?" He held out a small sack.

Spilling out the sack, Bob found that it contained about two dozen large rubies, emeralds and diamonds.

"We can't take it," Bob said. "We can't do business with you."

"Don't be superst.i.tious!" Janice shouted, seeing their marriage begin to evaporate again.

"Why not?" the ferra asked.

"We can't introduce modern things into the past," Bob said. "It'll change the present This world may vanish or something."

"Oh, don't worry about that," the ferra said. "I guarantee nothing will happen."

"But why? I mean, if you introduced a washer in ancient Rome-"

"Unfortunately," the ferra said, "King Alerian's kingdom has no future."

"Would you explain that?"

"Sure." The ferra sat down on the air. "In three years King Alerian and his country will be completely and irrevocably destroyed by forces of nature. Not a person will be saved. Not even a piece of pottery."

"Fine," Janice said, holding a ruby to the light. "We'd better unload while he's still in business."

"I guess that takes care of that," Bob said. Their business was saved, and their marriage was in the immediate future. "How about you?" he asked the ferra.

"Well, I've done rather well on this job," the ferra said. "I think I'll apply for a foreign transfer. I hear there are some wonderful opportunities in Arabian sorcery."

He ran a hand complacently over his blond crew cut "I'll be seeing you," he said, and started to disappear.

"Just a minute," Bob said. "Would you mind telling me what country you're from? And what country King Alerian is from?"

"Oh, sure," the ferra said, only his head still visible. "I thought you knew. Ferras are the demons of Atlantis."

And he disappeared.

WARM.

Anders lay on his bed, fully dressed except for his shoes and black bow tie, contemplating, with a certain uneasiness, the evening before him. In twenty minutes he would pick up Judy at her apartment, and that was the uneasy part of it.

He had realized, only seconds ago, that he was in love with her.

Well, he'd tell her. The evening would be memorable. He would propose, there would be kisses, and the seal of acceptance would, figuratively speaking, be stamped across his forehead.

Not too pleasant an outlook, he decided. It really would be much more comfortable not to be in love. What had done it? A look, a touch, a thought? It didn't take much, he knew, and stretched his arms for a thorough yawn.

"Help me!" a voice said.

His muscles spasmed, cutting off the yawn in mid-moment. He sat upright on the bed, then grinned and lay back again.

"You must help me!" the voice insisted.

Anders sat up, reached for a polished shoe and fitted it on, giving his full attention to the tying of the laces.

"Can you hear me?" the voice asked. "You can, can't you?"

That did it "Yes, I can hear you," Anders said, still in a high good humor. "Don't tell me you're my guilty subconscious, attacking me for a childhood trauma I never bothered to resolve. I suppose you want me to join a monastery."

"I don't know what you're talking about," the voice said. "I'm no one's subconscious. I'm me. Will you help me?"

Anders believed in voices as much as anyone; that is, he didn't believe in them at all, until he heard them. Swiftly he cataloged the possibilities. Schizophrenia was the best answer, of course, and one in which his colleagues would concur. But Anders had a lamentable confidence in his own sanity. In which case- "Who are you?" he asked.

"I don't know," the voice answered.

Anders realized that the voice was speaking within his own mind. Very suspicious.

"You don't know who you are," Anders stated. "Very well. Where are you?"

"I don't know that, either." The voice paused, then went on. "Look, I know how ridiculous this must sound. Believe me, I'm in some sort of limbo. I don't know how I got here or who I am, but I want desperately to get out. Will you help me?"

Still fighting the idea of a voice speaking within his head, Anders knew that his next decision was vital. He had to accept-or reject-his own sanity.

"All right," Anders said, lacing the other shoe. "I'll grant that you're a person in trouble, and that you're in some sort of telepathic contact with me. Is there anything else you can tell me?"

"I'm afraid not," the voice said, with infinite sadness. "You'll have to find out for yourself."

"Can you contact anyone else?"

"No."

"Then how can you talk with me?"

"I don't know."

Anders walked to his bureau mirror and adjusted his black bow tie, whistling softly under his breath. Having just discovered that he was in love, he wasn't going to let a little thing like a voice in his mind disturb him.

"I really don't see how I can be of any help," Anders said, brushing a bit of lint from his jacket. "You don't know where you are, and there don't seem to be any distinguishing landmarks. How am I to find you?" He turned and looked around the room to see if he had forgotten anything.

"I'll know when you're close," the voice said. "You were warm just then."

"Just then?" All he had done was look around the room. He did so again, turning his head slowly. Then it happened.

The room, from one angle, looked different. It was suddenly a mixture of muddled colors, instead of the carefully blended pastel shades he had selected. The lines of wall, floor, and ceiling were strangely off proportion, zigzag, unrelated.

Then everything went back to normal.

"You were very warm," the voice said.

Anders resisted the urge to scratch his head, for fear of disarranging his carefully combed hair. What he had seen wasn't so strange. Everyone sees one or two things in his life that make him doubt his normality, doubt sanity, doubt his very existence. For a moment the orderly Universe is disarranged and the fabric of belief is ripped.

But the moment pa.s.ses.

Anders remembered once, as a boy, awakening in his room in the middle of the night. How strange everything had looked! Chairs, table, all out of proportion, swollen in the dark. The ceiling pressing down, as in a dream.

But that also had pa.s.sed.

"Well, old man," he said, "if I get warm again, tell me."

"I will," the voice in his head whispered. "I'm sure you'll find me."

"I'm glad you're so sure," Anders said gaily, switched off the lights and left.

Lovely and smiling, Judy greeted him at the door. Looking at her, Anders sensed her knowledge of the moment. Had she felt the change in him, or predicted it? Or was love making him grin like an idiot?

"Would you like a before-party drink?" she asked.

He nodded, and she led him across the room, to the improbable green-and-yellow couch. Sitting down, Anders decided he would tell her when she came back with the drink. No use in putting off the fatal moment. A lemming in love, he told himself.

"You're getting warm again," the voice said.

He had almost forgotten his invisible friend. Or fiend, as the case could well be. What would Judy say if she knew he was hearing voices? Little things like that, he reminded himself, often break up the best of romances.

"Here," she said, handing him a drink.

Still smiling, he noticed. The number two smile-to a prospective suitor, provocative and understanding. It had been preceded, in their relationship, by the number one nice-girl smile, the don't-misunderstand-me smile, to be worn on all occasions, until the correct words have been mumbled.

"That's right," the voice said. "It's in how you look at things."

Look at what? Anders glanced at Judy, annoyed at his thoughts. If he was going to play the lover, let him play it. Even through the astigmatic haze of love, he was able to appreciate her blue-gray eyes, her fine skin (if one overlooked a tiny blemish on the left temple), her lips, slightly reshaped by lipstick.

"How did your cla.s.ses go today?" she asked.

Well, of course she'd ask that, Anders thought. Love is marking time.

"All right," he said. "Teaching psychology to young apes."

"Oh, come now!"

"Warmer," the voice said.

What's the matter with me, Anders wondered. She really is a lovely girl. The gestalt that is Judy, a pattern of thoughts, expressions, movements, making up the girl I- I what?

Love?

Anders shifted his long body uncertainly on the couch. He didn't quite understand how this train of thought had begun. It annoyed him. The a.n.a.lytical young instructor was better off in the cla.s.sroom. Couldn't science wait until 9:10 in the morning?

"I was thinking about you today," Judy said, and Anders knew that she had sensed the change in his mood.

"Do you see?" the voice asked him. "You're getting much better at it."

"I don't see anything," Anders thought, but the voice was right. It was as though he had a clear line of inspection into Judy's mind. Her feelings were nakedly apparent to him, as meaningless as his room had been in that flash of undistorted thought "I really was thinking about you," she repeated.

"Now look," the voice said.

Anders, watching the expressions on Judy's face, felt the strangeness descend on him. He was back in the nightmare perception of that moment in his room. This time it was as though he were watching a machine in the laboratory. The object of this operation was the evocation and preservation of a particular mood. The machine goes through a searching process, invoking trains of ideas to achieve the desired end.

"Oh, were you?" he asked, amazed at his new perspective.

"Yes...I wondered what you were doing at noon," the reactive machine opposite him on the couch said, expanding its shapely chest slightly.

"Good," the voice said, commending him for his perception.

"Dreaming of you, of course," he said to the flesh-clad skeleton behind the total gestalt Judy. The flesh machine rearranged its limbs, widened its mouth to denote pleasure. The mechanism searched through a complex of fears, hopes, worries, through half-remembrances of a.n.a.logous situations, a.n.a.logous solutions.

And this was what he loved. Anders saw too clearly and hated himself for seeing. Through his new nightmare perception, the absurdity of the entire room struck him.

"Were you really?" the articulating skeleton asked him.

"You're coming closer," the voice whispered.

To what7 The personality? There was no such thing. There was no true cohesion, no depth, nothing except a web of surface reactions, stretched across automatic visceral movements.

He was coming closer to the truth.

"Sure," he said sourly.

The machine stirred, searching for a response.

Anders felt a quick tremor of fear at the sheer alien quality of his viewpoint. His sense of formalism had been sloughed off, his agreed-upon reactions bypa.s.sed. What would be revealed next?

He was seeing clearly, he realized, as perhaps no man had ever seen before. It was an oddly exhilarating thought.

But could he still return to normality?

"Can I get you a drink?" the reaction machine asked.

At that moment Anders was as thoroughly out of love as a man could be. Viewing one's intended as a depersonalized, s.e.xless piece of machinery is not especially conducive to love. But it is quite stimulating, intellectually.

Anders didn't want normality. A curtain was being raised and he wanted to see behind it. What was it some Russian scientist-Ouspensky, wasn't it-had said?
