Josie O'Conner travels to San Francisco in 1951 to locate her gay brother, a private dick investigating a blackmail ring targeting lesbians and gay men. Jimmy's friends claim that just before he disappeared he became a rat, informing the cops on the bar community. Josie adopts Jimmy's trousers and wingtips, battling to clear his name, halt the blackmailers, and exact justice for the many queer corpses. Along the way she rubs shoulders with a sultry chanteuse running a dyke tavern called Pandora's Box, gets intimate with a red-headed madam operating a brothel from the Police Personnel Department, and conspires with the star of Finocchio's, a dive so disreputable it's off limits to servicemen - so every man in uniform pays a visit.

Blackmail, My Love is a murder mystery deeply steeped in San Francisco's queer history. Established academic and first-time novelist Katie Gilmartin's diverse set of characters negotiate the risks of same-sex desire in a tough time for queers. Humor leavens the grave subject matter. Set in such legendary locations as the Black Cat Cafe, the Fillmore, the Beat movement's North Beach, and the sexually complex Tenderloin, Blackmail, My Love is a singular, visually stunning neo-noir experience.
