This is nothing to do with the Oxford street, but a medieval whodunnit set in Tiverton in 1321, at the time of St Giles's feast. Philip Dyne has confessed to murder and claimed sanctuary in St Peter's Church. As Sir Baldwin Furnshill, Keeper of the King's Peace, and Bailiff Simon Puttock arrive at Lord Hugh de Courtenay's castle for the feast, another body is found Sir Gilbert of Carlisle, an important ambassador lying near the decapitated figure of Dyne. The coroner is satisfied that Dyne killed the knight and was then murdered; Dyne was an outlaw, so he doesn't merit the law's attention. But Sir Baldwin feels too many questions are left unanswered.
