"The ninth entry in the acclaimed medieval mystery series. 1321 and Tiverton is preparing for the Feast of St. Giles. Philip Dyne is in the church of St. Peter's, claiming sanctuary for murder. He agrees to abjure the realm, and sets off as a penitent. Sir Baldwin and Simon arrive at Sir Hugh de Courtenay's castle at Tiverton, just as another body is found, that of Sir Gilbert of Carlisle, discovered near the decapitated body of Dyne. Sir Gilbert's horse and money are gone, but the coroner is keen to close the matter and declare that Dyne killed the knight and was then slain as an outlaw."@en
