Mr. Wolesky unlocked his door, lurched inside, and slammed the door after himself. The door lock clicked into place, and I heard Mr. Wolesky's television go on.

Diesel elbowed me aside, went into the hall, and retrieved his boots. "You know, you have a real attitude problem," he said.

"Attitude this," I told him, closing my door, locking him out of the apartment.

The bolt shot back, the lock tumbled, and Diesel opened the door, walked to the couch, and sat down to put his boots on.

Hard to pick an emotion here. Confused and astounded would be high on the list. Scared bonkers wasn't far behind. "How'd you do that?" I said, squeaky-voiced and breathless. "How'd you unlock my door?"

"I don't know. It's just one of those things we can do."

Goosebumps prickled on my forearms. "Now I'm really creeped out."

"Relax. I'm not going to hurt you. Hell, I'm supposed to make your life better." He gave a snort and another bark of laughter at that. "Yeah, right," he said.

Deep breath, Stephanie. Not a terrific time to hyperventilate. If I passed out from lack of oxygen God knows what would happen. Suppose he was from outer space, and he conducted an anal probe while I was unconscious? A shiver ripped through me. Yuk! "What are we looking at here?" I asked him. "Ghost? Vampire? Space alien?"

He slouched back onto the couch and zapped the television on. "You're in the ballpark."

I was at a loss. How do you get rid of someone who can unlock locks? You can't even have him arrested by the police. And even if I decided to call the police, what would I say? I have a sort-of-real guy in my apartment?

"Suppose I cuffed you and chained you to something. What then?"

He was channel surfing, concentrating on the television. "I could get loose."

"Suppose I shot you?"

"I'd be pissed off. And it's not smart to piss me off."

"But could I kill you? Could I hurt you?"

"What is this, twenty questions? I'm looking for a game here. What time is it, anyway? And where am I?"

"You're in Trenton, New Jersey. It's eight o'clock in the morning. And you didn't answer my question."

He flipped the television off. "Crud. Trenton. I should have guessed. Eight in the morning. I have a whole day to look forward to. Wonderful. And the answer to your question is... a qualified no. It wouldn't be easy to kill me, but I suppose if you put your mind to it you could come up with something."

I went to the kitchen and phoned my next-door neighbor, Mrs. Karwatt. "I was wondering if you could come over for just a second," I said. "There's something I'd like to show you." A moment later, I ushered Mrs. Karwatt into my living room. "What do you see?" I asked her. "Is there anyone sitting on my couch?"
