“He thinks, um…,” I started and then trailed off. Deborah had no idea what I was, of course, and Harry had told me quite firmly to keep her in the dark. So how I could tell her about this without revealing anything was something of a problem. “He thinks the nurse is giving him too much morphine,” I finally said. “On purpose.”

“That's crazy,” Deb said. “She's a nurse.”

Harry looked at her but didn't say anything. And to be truthful, I couldn't think of anything to say to Deb's incredible naïveté either.

“What should I do?” I asked Harry.

Harry looked at me for a very long time. At first I thought his mind might have wandered away with the pain, but as I looked back at him I saw that Harry was very much present. His jaw was set so hard that I thought the bones might snap through his tender pale skin and his eyes were as clear and sharp as I had ever seen them, as much as when he had first given me his Harry solution to getting me squared away. “Stop her,” he said at last.

A very large thrill ran through me. Stop her? Was it possible? Could he mean-stop her? Until now Harry had helped me control my Dark Passenger, feeding him stray pets, hunting deer; one glorious time I had gone with him to catch a feral monkey that had been terrorizing a South Miami neighborhood. It had been so close, so almost human-but still not right, of course. And we had gone through all the theoretical steps of stalking, disposing of evidence, and so on. Harry knew that someday It would happen and he wanted me to be ready to do It right. He had always held me back from actually Doing It. But now-stop her? Could he mean it?

“I'll go talk to the doctor,” Deborah said. “He'll tell her to adjust your medicine.”

I opened my mouth to speak, but Harry squeezed my hand and nodded once, painfully. “Go,” he said, and Deborah looked at him for a moment before she turned away and went to find the doctor. When she was gone the room filled with a wild silence. I could think of nothing but what Harry had said: “Stop her.” And I couldn't think of any other way to interpret it, except that he was finally turning me loose, giving me permission to do the Real Thing at last. But I didn't dare ask him if that's what he had said for fear he would tell me he meant something else. And so I just stood there for the longest time, staring out the small window into a garden outside, where a splatter of red flowers surrounded a fountain. Time passed. My mouth got dry. “Dexter-” Harry said at last.

I didn't answer. Nothing I could think of seemed adequate. “It's like this,” Harry said, slowly and painfully, and my eyes jerked down to his. He gave me a strained half smile when he saw that I was with him at last. “I'll be gone soon,” Harry said. “I can't stop you from… being who you are.”

“Being what I am, Dad,” I said.

He waved it away with a feeble, brittle hand. “Sooner or later… you will-need-to do it to a person,” he said, and I felt my blood sing at the thought. “Somebody who… needs it…”

“Like the nurse,” I said with a thick tongue.

“Yes,” he says, closing his eyes for a long moment, and when he went on his voice had grown hazy with the pain. “She needs it, Dexter. That's-” He took a ragged breath. I could hear his tongue clacking as if his mouth was overdry. “She's deliberately-overdosing patients… killing them… killing them… on purpose… She's a killer, Dexter… A killer…”

I cleared my throat. I felt a little clumsy and light-headed, but after all this was a very important moment in a young man's life. “Do you want-” I said and stopped as my voice broke. “Is it all right if I… stop her, Dad?”

“Yes,” said Harry. “Stop her.”

For some reason I felt like I had to be absolutely certain. “You mean, you know. Like I've been doing? With, you know, the monkey?”

Harry's eyes were closed and he was clearly floating away on a rising tide of pain. He took a soft and uneven breath. “Stop… the nurse,” he said. “Like… the monkey…” His head arched back slightly, and he began to breathe faster but still very roughly.

Well.

There it was.

“Stop the nurse like the monkey.” It had a certain wild ring to it. But in my madly buzzing brain, everything was music. Harry was turning me loose. I had permission. We had talked about one day doing this, but he had held me back. Until now.

Now.

“We talked… about this,” Harry said, eyes still closed. “You know what to do…”

“I talked to the doctor,” Deborah said, hurrying into the room. “He'll come down and adjust the meds on the chart.”

“Good,” I said, feeling something rise up in me, from the base of my spine and out over the top of my head, an electric surge that jolted through me and covered me like a dark hood. “I'll go talk to the nurse.”

Deborah looked startled, perhaps at my tone. “Dexter-” she said.

I paused, fighting to control the savage glee I felt towering up inside me. “I don't want any misunderstanding,” I said. My voice sounded strange even to me. I pushed past Deborah before she could register my expression.

And in the hallway of that hospice, threading my way between stacks of clean, crisp, white linen, I felt the Dark Passenger become the new driver for the first time. Dexter became understated, almost invisible, the light-colored stripes on a sharp and transparent tiger. I blended in, almost impossible to see, but I was there and I was stalking, circling in the wind to find my prey. In that tremendous flash of freedom, on my way to do the Thing for the first time, sanctioned by almighty Harry, I receded, faded back into the scenery of my own dark self, while the other me crouched and growled. I would do It at last, do what I had been created to do.

And I did.

AND I HAD. SO LONG AGO, YET THE MEMORY STILL pulsed in me. Of course, I still had that first dry drop of blood on its slide. It was my first, and I could call up that memory any time by taking out my little slide and looking at it. I did, every so often. It had been a very special day for Dexter. Last Nurse had been First Playmate, and she had opened up so many wonderful doors for me. I had learned so much, found out so many new things.

But why was I remembering Last Nurse now? Why did this whole series of events seem to be whipping me back through time? I could not afford a fond remembrance of my first pair of long pants. I needed to explode into action, make large decisions, and begin important deeds. Instead of strolling sappily down memory lane, wallowing in sweet memories of my first blood slide.

Which, now that I thought of it, I had not collected from Jaworski. It was the kind of tiny, absurdly unimportant detail that turned strong men of action into fidgeting, whimpering neurotics. I needed that slide. Jaworski's death was useless without it. The whole idiotic episode was now worse than a stupid and impulsive foolishness; it was incomplete. I had no slide.

I shook my head, trying spastically to rattle two gray cells into the same synapse. I half wanted to take my boat for an early-morning spin. Perhaps the salt air would clear the stupidity from my skull. Or I could head south to Turkey Point and hope that the radiation might mutate me back into a rational creature. But instead, I made coffee. No slide, indeed. It cheapened the whole experience. Without the slide, I might as well have stayed home. Or almost, at any rate. There had been other rewards. I smiled fondly, recalling the mix of moonlight and muffled screams. Oh, what a madcap little monster I had been. An episode unlike any of my others. It was good to break out of dull routine from time to time. And there was Rita, of course, but I had no idea what to think about that, so I didn't. Instead I thought of the cool breeze flowing across the squirming little man who had liked to hurt children. It had almost been a happy time. But of course, in ten years the memory would fade, and without that slide I could not bring it back. I needed my souvenir. Well, we would see.
