Brother Cadfael is the main fictional character in a series of historical murder mysteries written between 1977 and 1994 by the linguist-scholar Edith Pargeter under the name Ellis Peters. The character of Cadfael himself is a Welsh Benedictine monk living at the Abbey Church of Saint Peter and Saint Paul, in Shrewsbury, western England, in the first half of the 12th century. The stories are set between about 1135 and about 1145, during "The Anarchy", the destructive contest for the crown of England between King Stephen and his cousin Empress Maud. As a character, Cadfael "combines the curious mind of a scientist/pharmacist with a knight-errant". He entered monastic life in his forties after being both a soldier and a sailor; this worldly experience gives him an array of talents and skills useful in monastic life. He is a skilled observer of human nature, inquisitive by nature, energetic, a talented herbalist (work he learned in the Holy Land), and has an innate, although modern, sense of justice and fair-play. Abbots call upon him as a medical examiner, detective, doctor, and diplomat. His worldly knowledge, although useful, gets him in trouble with the more doctrinaire characters of the series, and the seeming contradiction between the secular and the spiritual worlds forms a central and continuing theme of the stories.
