Thomas atte Bridge, a man no one likes, is found hanging from a tree near Cowleys Corner. All assume he has taken his own life, but Master Hugh and Kate find evidence that this may not be so.

Many of the town had been harmed by Thomas, and Hugh is not eager to send one of them to the gallows. Then he discovers that the priest John Kellet, atte Bridge's partner in crime in A Corpse at St. Andrew's Chapel, was covertly in Bampton at the time atte Bridge died.

Master Hugh is convinced that Kellet has murdered atte Bridge--one rogue slaughtering another. He sets out for Exeter, where Kellet now works. But there he discovers that the priest is an emaciated skeleton of a man, who mourns the folly of his past life. Hugh must return to Bampton and discover which of his friends has murdered his enemy.
