Three men have been murdered in a Sussex village, and Scotland Yard has been called in. It’s a baffling case. All the victims are soldiers who have made it home alive from the Great War, which ended two years ago, only to be garroted, with small ID disks left in their mouths. And shortly after Inspector Ian Rutledge arrives, there’s a fourth murder. The killer is vicious and clever, leaving behind few clues. As the stakes ratchet up, Rutledge is determined to find answers, even as he puts his job, his reputation, and even his life on the line.
