Married playboy "Merry Perry" Merithew lies dead on the roof of a squalid tenement on Manhattan's Lower East Side. His money, watch, and jeweled tie-pin are missing and the body's right hand is closed tightly around a sheared-off clump of long copper-colored hair. But Merithew's life was one long string of cast-off redheads. Is his killer millionaire's daughter and would-be social reformer Muriel Schuyler? His ex-mistress, sweatshop seamstress-turned-model Maryla Sokalski? The eyelash-fluttering vamp Aphra Shaler? Bowery pockpocket and gang hanger-on "Red Ida" Ganley? Society blackmailer "Pet" Bettany? The answer may lie in an amethyst-headed hatpin found at the crime scene...or in the guilty conscience of the killer herself.
