Midsummer, 1145. Walter, 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 to call in help. However, as the death appears to have not been an accident, he grudgingly receives Undersheriff Hugh Bradecote, Serjeant Catchpoll and Underserjeant Walkelin. The trio know to step carefully with the contentious undercurrents at play. As the sheriff's men investigate the steward's death, 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.
