Spanish Blood by Raymond Chandler

Pete Marcus, the big, sandy-haired dick, sat sidewise at a small littered desk in a bare office in which there were two such desks, faced to opposite walls. The other desk was neat and tidy, had a green blotter with an onyx pen set, a small brass calendar and an abalone shell for an ash tray.

A round straw cushion that looked something like a target was propped on end in a straight chair by the window. Pete Marcus had a handful of bank pens in his left hand and he was flipping them at the cushion, like a Mexican knife thrower. He was doing it absently, without much skill.
