The summer of 1273 is peaceful for most of England, except in the village of Tyndal, where Martin the cooper has been poisoned at the local inn. Martin had plenty of enemies; the killer could be anyone. Prioress Eleanor grieves for her friend, the newly bereaved Crowner Ralf, and offers what help she can. But when her own problems multiply, Eleanor has good reason to regret her kindness. Her new anchoress terrifies her servants and welcomes visitors to her window at night. One of those visitors is Brother Thomas, a man the prioress secretly loves and whose loyalty to her as head of Tyndal Priory is now suspect. Bodies multiply. Suspects disappear. No one likes the direction the evidence is pointing, but God's justice must be rendered-even for the forsaken soul.
