Killer in the Rain by Raymond Chandler

It was after five when I stopped opposite the apartment house on Randall Place. A few windows were lit up already and radios bleated discordantly on different programs. I rode the automatic elevator to the fourth floor. Apartment 405 was at the end of a long hall that was carpeted in green and paneled in ivory. A cool breeze blew through the hall from open doors to the fire escape.

There was a small ivory push button beside the door marked 405. I pushed it.
