What is the author's style in The High Window by Raymond Chandler?

A High Window is narrated by the main character, Philip Marlowe, a highly-observant man who has apparent disdain for many of the people he deals with through his profession. He is sarcastic and tough in his speech, always ready with a quick comment. Since his character provides most of the background narration and much of the dialogue, the novel assumes a tone that matches Marlowe's knowing, wise-guy persona.
