An astonishing tip from a grateful ex-convict seems implausible --- but Inspector Ian Rutledge is intrigued and brings it to his superior at Scotland Yard. Alan Barrington, who has evaded capture for 10 years, is the suspect in an appalling murder during Black Ascot, the famous 1910 royal horserace honoring the late King Edward VII. His disappearance began a manhunt that consumed Britain for a decade. Now it appears that Barrington has returned to England, giving the Yard a last chance to retrieve its reputation and see justice done. Rutledge is put in charge of a quiet search under cover of a routine review of a cold case. But his sanity is suddenly brought into question by a shocking turn of events.
