“I found where she lived. I kept ringing her bell. Nothing happened.”

“She sleeps late,” I said. “Works in a night spot.”

“I asked if I might run up to her apartment, and she said I could, that it was 309.

“I went up to the third floor in the elevator. As I started down the hall, a man came out of a room at the far end of the corridor. I don’t know — I think it was 309.”

“That’s probably why she didn’t answer the doorbell.”
