It is Summer in the Year of Our Lord 1139 when the grand festive event, St. Peter's Fair, is held in the town of Shrewsbury. The event brings pause to the ongoing civil war, as tradesman from across England and beyond arrive in the town for some much needed gaiety. That is, until the body of a wealthy trader is found in the River Severn. Was Thomas of Bristol the victim of murderous thieves? And if so, why were his valuables abandoned nearby? Brother Cadfael offers to help the merchant's lovely niece Emma. But while he is seaching for the killer, the man's wares are ransacked and two more men are murdered. Emma almost certainly knows more that she is telling, as others will soon realise. Cadfael desperately races to save the young girl, knowing that in a country at war with itself, betrayal can come from any direction, an even good intentions can kill.
