Arriving home from a pilgrim voyage, Sister Fidelma hears that her faithful Saxon companion, Brother Eadulf, is under sentence of death for murder. She hastens to the capital of Laigin, where he is being held, determined to appeal against the sentence. The crime took place at the abbey of Fearna where Fidelma clashes with the sinister Abbess Fainder. The evidence against Eadulf seems overwhelming - can he actually be guilty? Will Fidelma's emotional involvement blind her in her desperate search for the truth?

"The latest Sister Fidelma mystery is one of the best... an excellent mystery with rich helpings of evil and tension set within a culture struggling to keep its identity and laws in the face of pressure from the Roman Church. Peter Tremayne paints a believable picture of time and place with a set of lively and varied characters" - HISTORICAL NOVELS REVIEW

"Strong on historical whodunnit, as sharp as a sword and as colourful as any medieval manuscript" - NORTHERN ECHO
