"Over," he said, feeling glum. He had spent everything he had. A vacuum had consumed his worth. But the Plasma was the court of last appeal in matters of problem-solving. WHAT SHOULD I DO? he had asked the Plasma. In five days he would have the answer.

During the next five days, Rybus became considerably weaker. She still fixed her own meals, however, although she seemed to eat the same thing over and over again: a dish of high-protein macaroni with grated cheese sprinkled over it. One day he found her wearing dark glasses. She did not want him to see her eyes.

"My bad eye has gone berserk," she said dispassionately. "Rolled up in my head like a window shade." Spilled capsules and tablets lay everywhere around her on her bed. He picked up one of the half-empty bottles and saw that she was taking one of the most powerful analgesics available.

"M.E.D. is prescribing this for you?" he said, wondering, Is she in that much pain?

"I know somebody," Rybus said. "At a dome on IV. The food man brought it over to me."

"This stuff is addictive."

"I'm lucky to get it. I shouldn't really have it."

"I know you shouldn't."

"That goddam M.E.D." The vindictiveness of her tone was surprising. "It's like dealing with a lower life-form. By the time they get around to prescribing, and then getting the medication to you, Christ, you're an urn of ashes. I see no point in them prescribing for an urn of ashes." She put her hand up to her skull. "I'm sorry; I should keep my wig on when you're here."

"It doesn't matter," he said.

"Could you bring me some Coke? Coke settles my stomach."

From her refrigerator he took a liter bottle of cola and poured her a glass. He had to wash the glass first; there wasn't a clean one in the dome.

Propped up before her at the foot of her bed, she had her standard-issue TV set going. It gabbled away mindlessly, but no one was listening or watching. He realized that every time he came over she had it on, even in the middle of the night.

When he returned to his own dome, he felt a tremendous sense of relief, of an odious burden being lifted from him. Just to put physical distance between himself and her – that was a joy which raised his spirits. It's as if, he thought, when I'm with her I have what she has. We share the illness.

He did not feel like playing any Fox recordings so instead he put on the Mahler Second Symphony, The Resurrection. The only symphony scored for many pieces of rattan, he mused. A Ruthe, which looks like a small broom; they use it to play the bass drum. Too bad Mahler never saw a Morley wah-wah pedal, he thought, or he would have scored it into one of his longer symphonies.

Just as the chorus came in, his in-dome audio system shut down; an extrinsic override had silenced it.

"Transmission from Fomalhaut."

"Standing by."

"Use video, please. Ten seconds till start."

"Thank you," he said.

A readout appeared on his larger screen. It was the AI System, the plasma, replying a day early.

SUBJECT: RYBUS ROMMEY

ANALYSIS: THANATOUS

PROGRAM ADVICE: TOTAL AVOIDANCE ON YOUR PART

ETHICAL FACTOR: OBVIATED

**THANK YOU**

Blinking, McVane said reflexively, "Thank you." He had dealt with the Plasma only once before and he had forgotten how terse its responses were. The screen cleared; the transmission had ended.

He was not sure what "thanatous" meant, but he felt certain that it had something to do with death. It means she is dying, he pondered as he punched into the planet's reference bank and asked for a definition. It means that she is dying or may die or is close to death, all of which I know.

However, he was wrong. It meant producing death.

Producing, he thought. There is a great difference between death and producing death. No wonder the AI System had notified him that the ethical factor was obviated on his part.

She is a killer thing, he realized. Well, this is why is costs so much to consult the Plasma. You get – not a phony answer based on speculation – but an absolute response.

While he was thinking about it and trying to calm himself down, his telephone rang. Before he picked it up he knew who it was.

"Hi," Rybus said in a trembling voice.

"Hi," he said.

"Do you by any chance have any Celestial Seasonings Morning Thunder tea bags?"

"What?" he said.

"When I was over at your dome that time I fixed beef stroganoff for us, I thought I saw a canister of Celestial Seasonings -"

"No," he said. "I don't. I used them up."

"Are you all right?"

"I'm just tired," he said, and he thought, She said "us." She and I are an "us." When did that happen? he asked himself. I guess that's what the Plasma meant; it understood.

"Do you have any kind of tea?"

"No," he said. His in-dome audio system suddenly came back on, released from its pause mode now that the Fomalhaut transmission had ended. The choir was singing.

On the phone, Rybus giggled. "Fox is doing sound on sound? A whole chorus of a thousand -"

"This is Mahler," he said roughly.

"Do you think you could come over and keep me company?" Rybus asked. "I'm sort of at loose ends."

After a moment, he said, "Okay. There's something I want to talk to you about."

"I was reading this article in -"

"When I get there," he broke in, "we can talk. I'll see you in half an hour." He hung up the phone.

When he reached her dome, he found her propped up in bed, wearing her dark glasses and watching a soap opera on her TV. Nothing had changed since he had last visited her, except that the decaying food in the dishes and the fluids in the cups and glasses had become more dismaying.

"You should watch this," Rybus said, not looking up. "Okay; I'll fill you in. Becky is pregnant, but her boyfriend doesn't -"

"I brought you some tea." He set down four tea bags.

"Could you get me some crackers? There's a box on the shelf over the stove. I need to take a pill. It's easier for me to take medication with food than with water because when I was about three years old… you're not going to believe this. My father was teaching me to swim. We had a lot of money in those days; my father was a – well, he still is, although I don't hear from him very often. He hurt his back opening one of those sliding security gates at a condo cluster where…" Her voice trailed off; she had again become engrossed in her TV.

McVane cleared off a chair and seated himself.

"I was very depressed last night," Rybus said. "I almost called you. I was thinking about this friend of mine who's now – well, she's my age, but she's got a class 4-C rating in time-motion studies involving prism fluctuation rate or some damn thing. I hate her. At my age! Can you feature that?" She laughed.

"Have you weighed yourself lately?" he asked.

"What? Oh no. But my weight's okay. I can tell. You take a pinch of skin between your fingers, up near your shoulder, and I did that. I still have a fat layer."

"You look thin," he said. He put his hand on her forehead.

"Am I running a fever?"

"No," he said. He continued to hold his hand there, against her smooth damp skin, above her dark glasses. Above, he thought, the myelin sheath of nerve fibers which had developed the sclerotic patches which were killing her.

You will be better off, he said to himself, when she is dead.

Sympathetically, Rybus said, "Don't feel bad. I'll be okay. M.E.D. has cut my dosage of Vasculine. I only take it t.i.d. now – three times a day instead of four."

"You know all the medical terms," he said.

"I have to. They issued me a PDR. Want to look at it? It's around here somewhere. Look under those papers over there. I was writing letters to several old friends because while I was looking for something else I came across their addresses. I've been throwing things away. See?" She pointed and he saw sacks, paper sacks, of crumpled papers. "I wrote for five hours yesterday and then I started in today. That's why I wanted the tea; maybe you could fix me a cup. Put a whole lot of sugar in it and just a little milk."
