The potter's field - Ellis Peters

The year is 1143, and once again Brother Cadfael is forced to abandon the tranquility of his herb garden and use his knowledge of human nature to solve a murder- this time frighteningly close to home. When a newly ploughed field, recently given to the Abbey yields that body of a young woman, Cadfael is quickly thrown into a delicate situation. The field was once ownded by a local potter named Ruald, who deserted his beautiful wife to take monastic vows among the Benedictines. The woman was said to have gone away with a lover, but now it would appear otherwise. With the arrival of young Sulien Blount, a novice fleeing homeward from the civil war raging in East Anglia, the mysteries surrounding the corpse start to multiply.
