Another slice of medieval skullduggery from the surgeon-turned-sleuth Master Hugh, surgeon and bailiff, is asked to provide a sleeping potion for Sir Henry Burley, a friend and guest of Lord Gilbert at Bampton Castle. Sir Henry--with his current wife, a daughter by a first wife, two knights, two squires, and assorted servants--has outstayed his welcome at Bampton. The next morning, Sir Henry is found dead, eyes open, in his bed. Master Hugh, despite shrill accusations from the grieving widow, is asked by Lord Gilbert to determine the cause of death . . . which had nothing to do with the potion. The sixth tale following Hugh de Singleton, Rest Not in Peace is sure to find its place among fans of detective and medieval historical fiction.
