The Devil's Seal

Ireland, AD 671. When a curious deputation of religieux arrive in Cashel, death follows close behind. Sister Fidelma and her companion, Eadulf, seem unable to stem the bloodshed.

Is one of the deputation responsible? What was the Venerable Verax, the scholar from Rome, hiding? Was there an evil secret behind the austere Bishop Arwald? Indeed, what was the real reason behind Eadulf's brother Egric's unexpected appearance at Cashel - could he be the culprit?

Victims and suspects combine to make a tangled skein of mystery more complex and bloody than Fidelma and Eadulf have ever faced.
