Doc had this solemn human by the throat when I caught up with him.

“Tonight,” Doc was saying in his old voice that was as crackled and important as parchment, “tonight Man will reach the Moon. The golden Moon and the silver ship, symbols of greed. Tonight is the night when this is to happen.”

“Sure,” the man agreed severely, prying a little worriedly at Doc’s arthritic fingers that were clamped on his collar. “No argument. Sure, up we go. But leave me go or, so help me, I’ll fetch you one in the teeth!”

I came alongside and carefully started to lever the old man loose, one finger at a time. It had to be done this way. I had learned that during all these weeks and months. His hands looked old and crippled, but I felt they were the strongest in the world. If a half dozen winos in Seattle hadn’t helped me get them loose, Doc and I would have been wanted for the murder of a North American Mountie.

It was easier this night and that made me afraid. Doc’s thin frame, layered with lumpy fat, was beginning to muscle-dance against my side. One of his times was coming on him. Then at last he was free of the greasy collar of the human.

“I hope you’ll forgive him, sir,” I said, not meeting the man’s eyes. “He’s my father and very old, as you can see.” I laughed inside at the absurd, easy lie. “Old events seem recent to him.”

The human nodded, Adam’s apple jerking in the angry neon twilight. “‘Memory Jump,’ you mean. All my great-grandfathers have it. But Great-great-grandmother Lupos, funny thing, is like a schoolgirl. Sharp, you know. I ... Say, the poor old guy looks sick. Want any help?”

I told the human no, thanks, and walked Doc toward the flophouse three doors down. I hoped we would make it. I didn’t know what would happen if we didn’t. Doc was liable to say something that might nova Sol, for all I knew.

Martians approaching the corner were sensing at Doc and me. They were just cheap tourists slumming down on Skid Row. I hated tourists and especially I hated Martian tourists because I especially hated Martians. They were aliens. They weren’t men like Doc and me.

Then I realized what was about to happen. It was foolish and awful and true. I was going to have one of mine at the same time Doc was having his. That was bad. It had happened a few times right after I first found him, but now it was worse. For some undefinable reason, I felt we kept getting closer each of the times.

I tried not to think about it and helped Doc through the fly-specked flophouse doors.

The tubercular clerk looked up from the gaudy comics sections of one of those little tabloids that have the funnies a week in advance.

“Fifteen cents a bed,” he said mechanically.

“We’ll use one bed,” I told him. “I’ll give you twenty cents.” I felt the round hard quarter in my pocket, sweaty hand against sticky lining.

“Fifteen cents a bed,” he played it back for me.

Doc was quivering against me, his legs boneless.

“We can always make it over to the mission,” I lied.

The clerk turned his upper lip as if he were going to spit. “Awright, since we ain’t full up. In advance.”

I placed the quarter on the desk.

“Give me a nickel.”

The clerk’s hand fell on the coin and slid it off into the unknown before I could move, what with holding up Doc.

“You’ve got your nerve,” he said at me with a fine mist of dew. “Had a quarter all along and yet you Martian me down to twenty cents.” He saw the look on my face. “I’ll give you a room for the two bits. That’s better’n a bed for twenty.”

I knew I was going to need that nickel. Desperately. I reached across the desk with my free hand and hauled the scrawny human up against the register hard. I’m not as strong in my hands as Doc, but I managed.

“Give me a nickel,” I said.

“What nickel?” His eyes were big, but they kept looking right at me. “You don’t have any nickel. You don’t have any quarter, not if I say so. Want I should call a cop and tell him you were flexing a muscle?”

I let go of him. He didn’t scare me, but Doc was beginning to mumble and that did scare me. I had to get him alone.

“Where’s the room?” I asked.

The room was six feet in all directions and the walls were five feet high. The other foot was finished in chicken wire. There was a wino singing on the left, a wino praying on the right, and the door didn’t have any lock on it. At last, Doc and I were alone.

I laid Doc out on the gray-brown cot and put his forearm over his face to shield it some from the glare of the light bulb. I swept off all the bedbugs in sight and stepped on them heavily.

Then I dropped down into the painted stool chair and let my burning eyes rest on the obscene wall drawings just to focus them. I was so dirty, I could feel the grime grinding together all over me. My shaggy scalp still smarted from the alcohol I had stolen from a convertible’s gas tank to get rid of Doc’s and my cooties. Lucky that I never needed to shave and that my face was so dirty, no one would even notice that I didn’t need to.

The cramp hit me and I folded out of the chair onto the littered, uncovered floor.

It stopped hurting, but I knew it would begin if I moved. I stared at a jagged cut-out nude curled against a lump of dust and lint, giving it an unreal distortion.

Doc began to mumble louder.

I knew I had to move.

I waited just a moment, savoring the painless peace. Then, finally, I moved.

I was bent double, but I got from the floor to the chair and found my notebook and orb-point in my hands. I found I couldn’t focus both my mind and my eyes through the electric flashes of agony, so I concentrated on Doc’s voice and trusted my hands would follow their habit pattern and construct the symbols for his words. They were suddenly distinguishable.

“Outsider... Thoth... Dyzan... Seven... Hsan... Beyond Six, Seven, Eight... Two boxes... Ralston... Richard Wentworth... Jimmy Christopher... Kent Allard... Ayem... Oh, are... see...”

His voice rose to a meaningless wail that stretched into non-existence. The pen slid across the scribbled face of the notebook and both dropped from my numb hands. But I knew. Somehow, inside me, I knew that these words were what I had been waiting for. They told everything I needed to know to become the most powerful man in the Solar Federation.

That wasn’t just an addict’s dream. I knew who Doc was. When I got to thinking it was just a dream and that I was dragging this old man around North America for nothing, I remembered who he was.

I remembered that he was somebody very important whose name and work I had once known, even if now I knew him only as Doc.

Pain was a pendulum within me, swinging from low throbbing bass to high screaming tenor. I had to get out and get some. But I didn’t have a nickel. Still, I had to get some.

I crawled to the door and raised myself by the knob, slick with greasy dirt. The door opened and shut--there was no lock. I shouldn’t leave Doc alone, but I had to.

He was starting to cry. He didn’t always do that.

I listened to him for a moment, then tested and tasted the craving that crawled through my veins. I got back inside somehow.

Doc was twisting on the cot, tears washing white streaks across his face. I shoved Doc’s face up against my chest. I held onto him and let him bellow. I soothed the lanks of soiled white hair back over his lumpy skull.

He shut up at last and I laid him down again and put his arm back across his face. (You can’t turn the light off and on in places like that. The old wiring will blow the bulb half the time.)

I don’t remember how I got out onto the street.

She was pink and clean and her platinum hair was pulled straight back, drawing her cheek-bones tighter, straightening her wide, appealing mouth, drawing her lean, athletic, feminine body erect. She was wearing a powder-blue dress that covered all of her breasts and hips and the upper half of her legs.

The most wonderful thing about her was her perfume. Then I realized it wasn’t perfume, only the scent of soap. Finally, I knew it wasn’t that. It was just healthy, fresh-scrubbed skin.

I went to her at the bus stop, forcing my legs not to stagger. Nobody would help a drunk. I don’t know why, but nobody will help you if they think you are blotto.

“Ma’am, could you help a man who’s not had work?” I kept my eyes down. I couldn’t look a human in the eye and ask for help. “Just a dime for a cup of coffee.” I knew where I could get it for three cents, maybe two and a half.

I felt her looking at me. She spoke in an educated voice, one she used, perhaps, as a teacher or supervising telephone operator. “Do you want it for coffee, or to apply, or a glass or hypo of something else?”

I cringed and whined. She would expect it of me. I suddenly realized that anybody as clean as she was had to be a tourist here. I hate tourists.

“Just coffee, ma’am.” She was younger than I was, so I didn’t have to call her that. “A little more for food, if you could spare it.”

I hadn’t eaten in a day and a half, but I didn’t care much.

“I’ll buy you a dinner,” she said carefully, “provided I can go with you and see for myself that you actually eat it.”

I felt my face flushing red. “You wouldn’t want to be seen with a bum like me, ma’am.”

“I’ll be seen with you if you really want to eat.”

It was certainly unfair and probably immoral. But I had no choice whatever.

“Okay,” I said, tasting bitterness over the craving.

The coffee was in a thick white cup before me on the counter. It was pale, grayish brown and steaming faintly. I picked it up in both hands to feel its warmth.

Out of the corner of my eye, I could see the woman sitting on the stool beside me. She had no right to intrude. This moment should be mine, but there she sat, marring it for me, a contemptible tourist.

I gulped down the thick, dark liquid brutally. It was all I could do. The cramp flowed out of my diaphragm. I took another swallow and was able to think straight again. A third swallow and I felt--good. Not abnormally stimulated, but strong, alert, poised on the brink of exhilaration.

That was what coffee did for me.

I was a caffeine addict.

Earth-norm humans sometimes have the addiction to a slight extent, but I knew that as a Centurian I had it infinitely worse. Caffeine affected my metabolism like a pure alkaloid. The immediate effects weren’t the same, but the need ran as deep.

I finished the cup. I didn’t order another because I wasn’t a pure sensualist. I just needed release. Sometimes, when I didn’t have the price of a cup, I would look around in alleys and find cola bottles with a few drops left in them. They have a little caffeine in them--not enough, never enough, but better than nothing.

“Now what do you want to eat?” the woman asked.

I didn’t look at her. She didn’t know. She thought I was a human--an Earth human. I was a man, of course, not an alien like a Martian. Earthmen ran the whole Solar Federation, but I was just as good as an Earthman. With my suntan and short mane, I could pass, couldn’t I? That proved it, didn’t it?

“Hamburger,” I said. “Well done.” I knew that would probably be all they had fit to eat at a place like this. It might be horse meat, but then I didn’t have the local prejudices.

I didn’t look at the woman. I couldn’t. But I kept remembering how clean she looked and I was aware of how clean she smelled. I was so dirty, so very dirty that I could never get clean if I bathed every hour for the rest of my life.

The hamburger was engulfed by five black-crowned, broken fingernails and raised to two rows of yellow ivory. I surrounded it like an ameba, almost in a single movement of my jaws.

Several other hamburgers followed the first. I lost count. I drank a glass of milk. I didn’t want to black out on coffee with Doc waiting for me.

“Could I have a few to take with me, miss?” I pleaded.

She smiled. I caught that out of the edge of my vision, but mostly I just felt it.

“That’s the first time you’ve called me anything but ‘ma’am’,” she said. “I’m not an old-maid schoolteacher, you know.”

That probably meant she was a schoolteacher, though. “No, miss,” I said.

“It’s Miss Casey--Vivian Casey,” she corrected. She was a schoolteacher, all right. No other girl would introduce herself as Miss Last Name. Then there was something in her voice...

“What’s your name?” she said to me.

I choked a little on a bite of stale bun.

I had a name, of course.

Everybody has a name, and I knew if I went off somewhere quiet and thought about it, mine would come to me. Meanwhile, I would tell the girl that my name was ... Kevin O’Malley. Abruptly I realized that that was my name.

“Kevin,” I told her. “John Kevin.”

“Mister Kevin,” she said, her words dancing with bright absurdity like waterhose mist on a summer afternoon, “I wonder if you could help me.”

“Happy to, miss,” I mumbled.

She pushed a white rectangle in front of me on the painted maroon bar. “What do you think of this?”

I looked at the piece of paper. It was a coupon from a magazine.

Dear Acolyte R. I. S.:

The world disoriented itself and I was on the floor of the somber diner and Miss Vivian Casey was out of sight and scent.

There was a five dollar bill tight in my fist. The counterman was trying to pull it out.

I looked up at his stubbled face. “I had half a dozen hamburgers, a cup of coffee and a glass of milk. I want four more ‘burgers to go and a pint of coffee. By your prices, that will be one sixty-five--if the lady didn’t pay you.”

“She didn’t,” he stammered. “Why do you think I was trying to get that bill out of your hand?”

I didn’t say anything, just got up off the floor. After the counterman put down my change, I spread out the five dollar bill on the vacant bar, smoothing it.

I scooped up my change and walked out the door. There was no one on the sidewalk, only in the doorways.

First I opened the door on an amber world, then an azure one. Neon light was coming from the chickenwire border of the room, from a window somewhere beyond. The wino on one side of the room was singing and the one on the other side was praying, same as before. Only they had changed around--prayer came from the left, song from the right.
