Moral Codes in The Maltese Falcon

“Spade emptied the unconscious man’s pockets one by one, working methodically, moving the lax body when necessary, making a pile of the pockets’ contents on the desk. When the last pocket had been turned out he returned to his own chair, rolled and lighted a cigarette, and began to examine his spoils. He examined them with grave unhurried thoroughness.”
