Raymond Chandler Quote

Undoubtedly the stories about them [hard-boiled detectives] had a fantastic element. Such things happened, but not so rapidly, nor to so close-knit a group of people, nor within so narrow a frame of logic. This was inevitable because the demand was for constant action; if you stopped to think you were lost. When in doubt, have a man come through a door with a gun in his hand.
