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, since foul play is suspected, he is relieved by the arrival of Undersheriff Hugh Bradecote, Serjeant Catchpoll and Underserjeant Walkelin. As the sheriff 's men investigate the steward's death, stepping carefully around contentious undercurrents, 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.
