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.)
