The Subtle Serpent by Peter Tremayne

3.0

The fourth Sister Fidelma novel, The Subtle Serpent, opens with a double mystery. Fidelma is on her way to the religious community of The Salmon of the Three Wells, located within the kingdom of her brother King Colgu, to investigate the murder of an unknown woman - her body found naked, headless, in a well, clutching a simple cross. While en route, the ship she is travelling on encounters an abandoned Gaullish merchant ship. Her cargo holds are empty, there are signs of blood recently shed, and perhaps worst of all, in one of the cabins Fidelma finds a book she had given as a gift to her dear companion of earlier adventures, Brother Eadulf.

As Fidelma seeks to solve both mysteries, she becomes aware that there is something very strange going on in the abbey and the surrounding community. There is open conflict between the abbess, Draigen, and the local chief, Adnar. Draigen herself is both arrogant and ambitious, and seems at times to be trying to impede Fidelma’s investigation. The abbey itself seems subtly wrong to Fidelma - there are few older members, and one of them, Bronach, is treated with much disrespect, as is Bronach’s protegee, Berrach, a severely disabled sister. Two sisters are missing - overdue to return from an errand - and though the younger one’s physical description matches the body, the abbess insists it cannot be her. And there is something strange about the abbey itself - sometimes strange noises seem to issue from the earth below the abbey, which Draigen says are the result of tidal water filling caves that riddle the area.

Meanwhile, Ross has been investigating the abandoned ship, and has discovered that it was brought to shore nearby, by a party of Irish warriors of the clan Ui Fidgenti, who pit the crew to work in the local copper mines. The ship itself vanished overnight while the Ui Fidgenti celebrated.

Fidelma finds things to concern her at Asnar’s stronghold as well. Draigen’s former husband, Ferbal, a bitter misogynist, lives in the compound. Adnar has guests - Torcan, prince of Ui Fidgenti and his companions, and Olcan, son of the local overlord, both families with ambition and grudes against her brother. And everywhere, in the abbey, on the abandoned vessel, even on the books in the abbey, Fidelma finds traces of an unusual red clay, commonly found in copper mines.

Another satisfying mystery from Peter Tremayne, complex and rich in atmosphere, drawing on both Irish history and legend, and the history of the Irish and Roman churches and the conflicts between them. Fidelma must uncover the secrets of the community, and of politics and greed, to solve the mysteries, and then, perhaps most satisfying of all, she sets forth fir new adventures with Eadulf at her side.
