A boy bishop is chosen in Lavenham, and in Mary Pettiman's assessment, 'Bishop o' Satan' is a fair description. Mark Fosser blackmails his neighbours with cheerful ecumenism, and when he turns up dead, the suspects might be considered to include most of the town census. Felica and Robin look into the matter for the sake of the innocent, and also uncover more about the unsavoury and inbred Fosser family than they might have liked. Warning: death of a child character and family violence.
