The dead body of an elderly man is found hidden in a sack at the Abbey, and Cadfael believes he was murdered. The principal suspects are a group of pilgrims, who include two known thieves. Cadfael locks them up, in a bid to draw out the killer.
Cadfael is the name given to the TV series of The Cadfael Chronicles adaptations produced by British television company ITV Central between 1994 and 1998. The series was broadcast on the ITV network in the UK, and starred Sir Derek Jacobi as the medieval detective.
