Midsummer, 1145. The steward of Evesham Abbey is found dead at the bottom of a well pit. The Abbot, whose relationship with the lord Sheriff of Worcestershire is strained at best, dislikes needing external help with the unfortunate incident. However, he grudgingly receives the trio of Undersheriff Hugh Bradecote, Serjeant Catchpoll and Underserjeant Walkelin. As the sheriff's men probe who had more reason to want Walter the Steward dead, they discover that truth is in short supply. With the tensions between the Abbey and the local castle guard reaching boiling point, another killing will force the investigation down a dangerous path.
