The Devil's Seal

An Anglo-Saxon deputation arrives in Cashel to debate the new religious rules from Rome. The Abbot of Imleach leads the Irish delegation and among the Anglo-Saxon delegation is Brother Eadulf’s younger brother Egric. There is also an observer appointed from Rome - the Venerable Favorinus. The debate is acrimonious and local Abbess Dar Óma has to step in as a mediator. But that evening her body is discovered. The animosity between the two sides is heightened as the Chief Brehon Aillín accuses Egric of murder. The Venerable Favorinus counter claims that the murderer is Brother Madagan who is steward to Abbot of Imleach. Sister Fidelma is compelled to resolve the mystery as she is sure there is something more sinister behind the murder.
