In May 1195, a Jewish moneylender is suffocated and a biblical verse is left beside his body. Further victims—a sex worker, a corrupt priest and a burgess accused of abusing boys—are killed in ways that appear to punish their alleged sins.
Because the murderer can read Scripture and select texts for each death, John suspects someone educated within the Church. Exeter contains scores of clergy and many private grievances, so he must distinguish moral outrage from personal motive while preventing another carefully staged execution.
