Finger Man by Raymond Chandler

I got away from the Grand Jury a little after four, and then sneaked up the back stairs to Fenweather's office. Fenweather, the D. A., was a man with severe, chiseled features and the gray temples women love. He played with a pen on his desk and said: "I think they believed you. They might even indict Manny Tinnen for the Shannon kill this afternoon. If they do, then is the time you begin to watch your step."

I rolled a cigarette around in my fingers and finally put it in my mouth. "Don't put any men on me, Mr. Fenweather. I know the alleys in this town pretty well, and your men couldn't stay close enough to do me any good."
