Murder in the twelfth century is no different from murder today. There is still a dead body, though this time with an arrow through the heart instead of a bullet. There is still a need to bury the dead, to comfort the living — and to catch the murderer. When Brother Cadfael comes to a village in the Welsh hills, he finds himself doing all three of those things. And there is nothing simple about this death. The murdered man's daughter needs Cadfael's help in more ways than one. There are questions about the arrow. And the burial is the strangest thing of all...

In the February of the year of our Lord 1141, men march home from war to Shrewsbury, but the captured Sheriff Gilbert Prestcote is not among them. Elis, a young Welsh prisoner, is, and he is delivered to the Abbey of Saint Peter and Saint Paul to begin a tale that will test Brother Cadfael's sense of justice... and his heart. By good fortune, it seems, the prisoner can be exchanged as Sheriff Prestcote's ransom. What none expects is that good-natured Elis will be struck down by Cupid's arrow. The sherrif's own daughter holds him in thrall, and she too, is blind with passion. Now regaining her father means losing her lover. But then the sheriff ailing and frail, is brought to the abbey's infirmary and murdered there. Suspicion falls on the prisoner, who only has his Welsh honour to gain Brother Cadfael's help. And Cadfael gives it, not knowing the truth will be a trial for his own soul.
