England, 1954. On a train to London, Fitzwilliam meets Miss Pinkerton, who tells him that a killer is on the loose in the sleepy English village of Wychwood under Ashe. The villagers believe the deaths are accidents, but Miss Pinkerton knows otherwise — and when she’s later found dead on her way to Scotland Yard, Fitzwilliam feels he must find the killer before they can strike again.
