“Don’t talk, Mr. Chip,” the doctor said, listening to his stethoscope. He then rolled up Joe’s sleeve and began winding inflatable rubber fabric around his arm in preparation for the blood-pressure test.

“How’s my heart?” Joe asked.

“Appears normal,” the doctor said. “Although slightly fast.”

“See?” Joe said to Don Denny. “I’ve recovered.”

Denny said, “The others are dying, Joe.”

Half sitting up, Joe said, “All of them?”

“Everyone that’s left.” He held the can but did not use it.

“Pat, too?” Joe asked.

“When I got out of the elevator on the second floor here I found her. It had just begun to hit her. She seemed terribly surprised; apparently, she couldn’t believe it.” He set the can down again. “I guess she thought she was doing it. With her talent.”

Joe said, “That’s right; that’s what she thought. Why won’t you use the Ubik?”

“Hell, Joe, we’re going to die. You know it, and I know it.” He removed his horn-rimmed glasses and rubbed his eyes. “After I saw Pat’s condition I went into the other rooms, and that’s when I saw the rest of them. Of us. That’s why we took so long getting here; I had Dr. Taylor examine them. I couldn’t believe they’d dwindle away so fast. The acceleration has been so goddam great. In just the last hour—”

“Use the Ubik,” Joe said. “Or I’ll use it on you.”

Don Denny again picked up the can, again shook it, pointed the nozzle toward himself. “All right,” he said. “If that’s what you want. There really isn’t any reason not to. This is the end, isn’t it? I mean, they’re all dead; only you and I are left, and the Ubik is going to wear off you in a few hours. And you won’t be able to get any more. Which will leave me.” His decision made, Denny depressed the button of the spray can; the shimmering, palpitating vapor, filled with particles of metallic light that danced nimbly, formed at once around him. Don Denny disappeared, concealed by the nimbus of radiant, ergic excitement.

Pausing in his task of reading Joe’s blood pressure, Dr. Taylor twisted his head to see. Both he and Joe watched as the vapor now condensed; puddles of it glistened on the carpet, and down the wall behind Denny it drizzled in bright streaks.

The cloud concealing Denny evaporated.

The person standing there, in the center of the vaporizing stain of Ubik that had saturated the worn and dingy carpet, was not Don Denny.

An adolescent boy, mawkishly slender, with irregular black-button eyes beneath tangled brows. He wore an anachronistic costume: white drip-dry shirt, jeans and laceless leather slippers. Clothes from the middle of the century. On his elongated face Joe saw a smile, but it was a misshapen smile, a thwarted crease that became now almost a jeering leer. No two features matched: His ears had too many convolutions in them to fit with his chitinous eyes. His straight hair contradicted the interwoven, curly bristles of his brows. And his nose, Joe thought, too thin, too sharp, far too long. Even his chin failed to harmonize with the balance of his face; it had a deep chisel mark in it, a cleft obviously penetrating far up into the bone, Joe thought, as if at that point the manufacturer of this creature struck it a blow aimed at obliterating it. But the physical material, the base substance, had been too dense; the boy had not fractured and split apart. He existed in defiance of even the force that had constructed him; he jeered at everything else and it, too.

“Who are you?” Joe said.

The boy’s fingers writhed, a twitch protecting him evidently from a stammer. “Sometimes I call myself Matt, and sometimes Bill,” he said. “But mostly I’m Jory. That’s my real name—Jory.” Gray, shabby teeth showed as he spoke. And a grubby tongue.

After an interval Joe said, “Where’s Denny? He never came into this room, did he?” Dead, he thought, with the others.

“I ate Denny a long time ago,” the boy Jory said. “Right at the beginning, before they came here from New York. First I ate Wendy Wright. Denny came second.”

Joe said, “How do you mean ‘ate’?” Literally? he wondered, his flesh undulating with aversion; the gross physical motion rolled through him, engulfing him, as if his body wanted to shrink away. However, he managed more or less to conceal it.

“I did what I do,” Jory said. “It’s hard to explain, but I’ve been doing it a long time to lots of half-life people. I eat their life, what remains of it. There’s very little in each person, so I need a lot of them. I used to wait until they had been in half-life awhile, but now I have to have them immediately. If I’m going to be able to live myself. If you come close to me and listen—I’ll hold my mouth open—you can hear their voices. Not all of them, but anyhow the last ones I ate. The ones you know.” With his fingernail he picked at an upper incisor, his head tilted on one side as he regarded Joe, evidently waiting to hear his reaction. “Don’t you have anything to say?” he said.

“It was you who started me dying, down there in the lobby.”

“Me and not Pat. I ate her out in the hall by the elevator, and then I ate the others. I thought you were dead.” He rotated the can of Ubik, which he still held. “I can’t figure this out. What’s in it, and where does Runciter get it?” He scowled. “But Runciter can’t be doing it; you’re right. He’s on the outside. This originates from within our environment. It has to, because nothing can come in from outside except words.”

Joe said, “So there’s nothing you can do to me. You can’t eat me because of the Ubik.”

“I can’t eat you for a while. But the Ubik will wear off.”

“You don’t know that; you don’t even know what it is or where it comes from.” I wonder if I can kill you, he thought. The boy Jory seemed delicate. This is the thing that got Wendy, he said to himself. I’m seeing it face to face, as I knew I eventually would. Wendy, Al, the real Don Denny—all the rest of them. It even ate Runciter’s corpse as it lay in the casket at the mortuary; there must have been a flicker of residual protophasic activity in or near it, or something, anyhow, which attracted him.

The doctor said, “Mr. Chip, I didn’t have a chance to finish taking your blood pressure. Please lie back down.”

Joe stared at him, then said, “Didn’t he see you change, Jory? Hasn’t he heard what you’ve been saying?”

“Dr. Taylor is a product of my mind,” Jory said. “Like every other fixture in this pseudo world.”

“I don’t believe it,” Joe said. To the doctor he said, “You heard what he’s been saying, didn’t you?”

With a hollow whistling pop the doctor disappeared.

“See?” Jory said, pleased.

“What are you going to do when I’m killed off?” Joe asked the boy. “Will you keep on maintaining this 1939 world, this pseudo world, as you call it?”

“Of course not. There’d be no reason to.”

“Then it’s all for me, just for me. This entire world.”

Jory said, “It’s not very large. One hotel in Des Moines. And a street outside the window with a few people and cars. And maybe a couple of other buildings thrown in: stores across the street for you to look at when you happen to see out.”

“So you’re not maintaining any New York or Zurich or—”

“Why should I? No one’s there. Wherever you and the others of the group went, I constructed a tangible reality corresponding to their minimal expectations. When you flew here from New York I created hundreds of miles of countryside, town after town—I found that very exhausting. I had to eat a great deal to make up for that. In fact, that’s the reason I had to finish off the others so soon after you got here. I needed to replenish myself.”

Joe said, “Why 1939? Why not our own contemporary world, 1992?”

“The effort; I can’t keep objects from regressing. Doing it all alone, it was too much for me. I created 1992 at first, but then things began to break down. The coins, the cream, the cigarettes—all those phenomena that you noticed. And then Runciter kept breaking through from outside; that made it even harder for me. Actually, it would have been better if he hadn’t interfered.” Jory grinned slyly. “But I didn’t worry about the reversion. I knew you’d figure it was Pat Conley. It would seem like her talent because it’s sort of like what her talent does. I thought maybe the rest of you would kill her. I would enjoy that.” His grin increased.
