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.
