Expanded and revised, this 30th-anniversary edition guides readers over the fog-shrouded hills stalked by Sam Spade, the Continental Op, and other legendary characters created by San Francisco's most famous mystery writer, Dashiell Hammett. Detailing locations of interest, including all of Hammett's known residences and the majority of settings from The Maltese Falcon, this guidebook contains maps, self-guided tours, and photographs of Hammett-related locations from both then and now. A new preface by Jo Hammett, the detective writer's daughter and Edgar Award–nominated writer, is also included.
