Brother Cadfael discovers a murder amid the wreckage of Shrewsbury Castle in this mystery series featuring "a colorful and authentic medieval background" (Publishers Weekly). In the summer of 1138, war between King Stephen and the Empress Maud takes Brother Cadfael from the quiet world of his garden into a battlefield of passions, deceptions, and death. Not far from the safety of the abbey walls, Shrewsbury Castle falls, leaving its ninety-four defenders loyal to the empress to hang as traitors. With a heavy heart, Brother Cadfael agrees to bury the dead, only to make a grisly discovery: one extra victim that has been strangled, not hanged. This ingenious way to dispose of a corpse tells Brother Cadfael that the killer is both clever and ruthless. But one death among so many seems unimportant to all but the good Benedictine. He vows to find the truth behind disparate clues: a girl in boy's clothing, a missing treasure, and a single broken flower . . . the tiny bit of evidence that Cadfael believes can expose a murderer's black heart.

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.
