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.
The Sister Fidelma novels are taking on almost cult proportions and are becoming ever more popular with each offering from the author, whose obvious knowledge of the times and subjects he writes about shines out like a beacon on the shore.
As Sister Fidelma and Brother Eadulf are preparing to leave the shores of England and return to Ireland, they receive a mysterious summons from a boyhood friend of Eadulf, Brother Botulf. He has requested their presence at a nearby Abbey. Eadul and Fidelma battle their way through a winter storm to reach the Abbey, but when they arrive they find that Botulf is dead, killed by an unknown person. Staggered by the murder of his boyhood friend Eadulf, with the help of Fidelma search for the truth, but it soon becomes apparent that the death of Botulf is not the only trouble facing the abbey.
