November 1918. A socialist revolution is sweeping across Germany, wreaking havoc on war-torn Berlin. Amid the ruin of the city's slums, four women are found dead-all with identical scars on their backs. Detective Inspector Nikolai Hoffner and his assistant, Hans Fichte, are baffled by the killings, and when another body is discovered, the case takes an ominous and unexpected turn. The fifth victim is none other than Rosa Luxemburg-a leader of the suppressed socialist uprising. Now, the Polpo, political police, are interested in the murders, and the mystery of Rosa's death leads Hoffner into the heart of Weimar's political turmoil, where ideas can be fatal.A spellbinding historical thriller from the author of The Second Son and Shadow and Light, Rosa is "a ghostly noir that could have been conspired at by Raymond Chandler and André Malraux . . . astonishing" (John Leonard, Harper's Magazine).
