It is winter 1372, York. A man has drowned in the River Ouse after a skirmish with boys from St Peter's School. It soon becomes clear that his death was not an accident - but why would a humble pilot on the river be killed for possessing a young boy's purse? Suspicion falls on Father Nicholas Ferriby - Vicar of Weston and master of a small grammar school - who has already offended many with his unpopular beliefs. But is he really a murderer? One-eyed spy, Owen Archer, Captain of Archbishop Thoresby's guard and noted for solving many crimes, is quickly brought to the scene by his adoptive son, Jasper. Clear that the pilot has been killed for more than a purse, an increasingly cantankerous Thoresby reluctantly agrees to let Owen investigate the man's murder. Torn between solving the crime and looking after his wife, Lucie, who is expecting their long-awaited third child, Owen is soon taken away from home. When another body is found in the river and Owen and Jasper get nearer to the truth, they find their own lives in jeopardy...--This text refers to the Hardcover edition.
