Monk's Hood

Brother Cadfael is confounded when his own potion is used to kill his former love's new husband

Gervase Bonel is a guest of Shrewsbury Abbey of Saint Peter and Saint Paul when he suddenly takes ill. Luckily, the abbey boasts the services of the clever and kindly Brother Cadfael, a skilled herbalist. Cadfael hurries to the man's bedside, only to be confronted with two surprises: In Master Bonel's wife, the good monk recognizes Richildis, whom he loved before he took his vows—and Master Bonel has been fatally poisoned by monk's-hood oil from Cadfael's stores.

The sheriff is convinced that the murderer is Richildis's son, Edwin, who hated his stepfather. But Cadfael, guided in part by his concern for a woman to whom he was once betrothed, is certain of her son's innocence. Using his knowledge of both herbs and the human heart, Cadfael deciphers a deadly recipe for murder.

Ellis Peters is a pseudonym of Edith Mary Pargeter (1913–1995), a British author whose Chronicles of Brother Cadfael are credited with popularizing the historical mystery. Cadfael, a Welsh Benedictine monk living at Shrewsbury Abbey in the first half of the twelfth century, has been described as combining the curious mind of a scientist with the bravery of a knight-errant. The character has been adapted for television, and the books drew international attention to Shrewsbury and its history.

Pargeter won an Edgar Award in 1963 for Death and the Joyful Woman, and in 1993 she won the Cartier Diamond Dagger, an annual award given by the Crime Writers’ Association of Great Britain. She was appointed officer of the Order of the British Empire in 1994, and in 1999 the British Crime Writers’ Association established the Ellis Peters Historical Dagger award, later called the Ellis Peters Historical Award.
