“I don’t see what you’re getting at.”

“If she hadn’t,” I said, “you’d have tried to find out why, wouldn’t you?”

“Naturally.”

I said, “The body was found in an apartment. The people in the adjoining apartment had been out from eight-fifty to nine-twenty. This made it very nice for you. You were able to narrow the crime down to a thirty-minute interval and start asking questions, accordingly. Well, if a woman had killed him, that would have been all right.”
