February AD 668 & Cashel is full of distinguished visitors. Under the old Irish custom Fidelma of Cashel & Eadulf of Seaxmund's Ham having been joined together for a year & a day are to be married. But on the eve of the ceremony the pious Abbot Ultan is found murdered in his chamber. Worse still
- one of the most distinguished guests the King of Connacht is seen fleeing from the scene & charged with the murder. He demands his right to appoint Fidelma in his defence. Fidelma soon discovers that Abbot Ultan is not the pious man he was thought to be -- indeed many of the guests have cause to hate him. It is a long weekend of suspicion fear & more death before Fidelma & Eadulf are able to reveal the truth behind Ultan's murder.
