The Wednesday is Murder Mystery Book Group meets to discuss The Maltese Falcon by Dashiell Hammett. A treasure worth killing for. Sam Spade, a slightly shopworn private eye with his own solitary code of ethics. A perfumed grafter named Joel Cairo, a fat man named Gutman and Brigid O'Shaughnessy, a beautiful and treacherous woman. These are the ingredients of Dashiell Hammett's coolly glittering gem of detective fiction.
