When a woman confesses to Father Will, one of the monk-constables at Maddleskirk Abbey, that she has committed murder, he can do nothing but absolve her from her sin. The Seal of Confession is absolute. He cannot discuss her crime, ask the identity of her victim, or share the responsibility of this information with anyone. His hands are tied. When a body is found in the nearby woodland, his moral dilemma grows. As the enquiry progresses and the clues confirm his fears that it is a murder case, Father Will must still not reveal his knowledge. Detective Chief Superintendent "Nabber" Napier and his team have a murder to solve, but monks sworn by oath to silence are hardly the ideal candidates for questioning...The search for the killer intensifies, and the team begin to uncover some disturbing facts. When the murder weapon is discovered, concealed in the Abbey, and the detectives learn of the mysterious disappearance - and violent past - of one of the Abbey's monks, the race is on to find the culprit before anybody else gets hurt. Questions need to be answered and confessions must be made.
