When I discovered that Cody was the same way, I had promised myself that I would carry on the Harry Way, pass on what I had learned to the boy, raise him up in Dark Righteousness. But this was an entire galaxy of complications, explanations, and teachings. It had taken Harry nearly ten years to cram it all into me before he allowed me to play with anything more complicated than stray animals. I had not even started with Cody-and although it made me feel like I was trying to be a Jedi Master, I could not possibly start with him now. I knew that Cody must someday come to terms with being like me, and I truly meant to help him-but not tonight. Not with the moon calling so playfully just outside the window, pulling at me like a soft yellow freight train hitched to my brain.

"I'm not, uh-" I started to say, meaning to deny everything. But they looked up at me with such an endearing expression of cold certainty that I stopped. "No," I said at last. "He's much too young." They exchanged a quick glance, no more, but there was an entire conversation in it. "I told him you would say that," Astor said.

"You were right," I said. "But Dexter," she said, "you said you would show us stuff."

"I will," I said, feeling the shadowy fingers crawl slowly up my spine and prodding for control, urging me out the door, "but not now." "When?" Astor demanded.

I looked at the two of them and felt the oddest combination of wild impatience to be off and cutting mixed with an urge to wrap them both in a soft blanket and kill anything that came near them. And nibbling at the edges, just to round out the blend, a desire to smack their thick little heads together.

Was this fatherhood at last? The entire surface of my body was tingling with cold fire from my need to be gone, to begin, to do the mighty unmentionable, but instead I took a very deep breath and put on a neutral face. "This is a school night," I said, "and it is almost your bedtime."

They looked at me as if I had betrayed them, and I supposed I had by changing the rules and playing Daddy Dexter when they thought they were talking to Demon Dexter. Still, it was true enough. One really can't take small children along on a late-night evisceration and expect them to remember their ABCs the next day. It was hard enough for me to show up at work the morning after one of my little adventures, and I had the advantage of all the Cuban coffee I wanted. Besides, they really were much too young.

"Now you're just being a grown-up," Astor said with a withering ten-year-old sneer.
