What is the author's style in Trouble Is My Business by Raymond Chandler?

Raymond Chandler wrote Trouble is My Business in 1934. It is a collection of four stories that center around the skills and escapades of a private detective named Philip Marlowe. The stories are told in authentic time period, using phrases that were common then, but have since been updated or changed. These words and phrases include such gems as wren instead of girl; gargle to mean drink; bucket in place of jail; fireflies to describe pearls; shamus instead of private detective; and a prowl car instead of patrol car and more.
