Master of souls - Peter Tremayne

On a storm-driven night, wreckers drive a merchant ship onto a rocky shore in Ireland. An abbess is slaughtered and six religieuse abducted. An ageing scholar is murdered in the Abbey of Ard Fhearta.

What is the link that connects these crimes? Who is the shadowy `master' spreading death and corruption across the land? Has the evil Uaman the Leper, Lord of the Passes, returned from the dead?

Sister Fidelma and her companion, Brother Eadulf, are asked to go to Ard Fhearta to examine the mystery. But the abbey stands in the territory of the U Fidgente, blood enemies of Fidelma and her brother, the King of Cashel. In this treacherous place, Fidelma and Eadulf find they have undertaken a most perilous journey.

Peter Tremayne is the fiction pseudonym of a well-known authority on the ancient Celts, who has utilised his knowledge of the Brehon law system and 7th-Century Irish society to create a new concept in detective fiction.
