Search - Act of Mercy (Sister Fidelma, Bk 8)

This is quite a series revolving around quite a culture. This one Fidelma solves aboard a ship

I really like this mystery series. If you like historical and/or Celtic stuff, you probably would, too.

Sister Fidelma sets out on a pilgrimage to the Holy Shrine of St. James in the late autumn of AD 666, her main goal being to reflect on her commitment to the religious life and her relationship with the Saxon monk, Eadulf, whom she has left behind. But duting the first night out, with the ship tossed about by a tempestuous sea, one of the pilgrims disappears, apparently washed overboard. The discovery of a blood-stained robe raises questions: was the pilgrim murdered and thrown into the sea? If so, why?
With the blessing of the captain, Fidelma has to focus all her abilities on solving the mystery. But death dogs the tiny band of pilgrims in the close confines of the ship, and Fidelma finds herself not only battling against the antagonism of her fellow pilgrims, but struggling to survive the turbulent elements of the storm-tossed sea. It is not until the Holy Shrine is almost reached - and time is running out - that the amazing truth is uncovered.
