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.
