In the gentle Shrewsbury spring of 1140 the midnight matins at the Benedictine abbey suddenly reverberates with an unholy sound - a hunt in full cry. Pursued by a drunken mob, the quarry is running for its life. When the frantic creature bursts into the nave to claim sanctuary, Brother Cadfael finds himself fighting off armed townsmen to save a terrified young man.

Accused of robbery and murder is Liliwin, a wandering minstrel who performed at the wedding of the local goldsmith's son. But his supposed victim, the miserly craftsman, is still alive, although a strongbox lies empty.

Brother Cadfael believes that Liliwin is innocent, but finding the truth and the treasure before Liliwin's respite in sanctuary runs out may uncover a deadlier sin than thievery - a desperate love that nothing, not even the threat of hanging, can stop.
