Blood on the Wind

Sister Fidelma Mysteries Book 37

By: Peter Tremayne

The thirty-seventh mystery in Peter Tremayne's long-standing and much-loved series, featuring 7th-century Irish super-sleuth Sister Fidelma.
AD 673.

Sister Fidelma and her husband Eadulf are journeying back from the Kingdom of the East Angles to Cashel when a violent storm wrecks their ship on the Isles of Sulis. Seeking shelter, they discover that Lowarn, the ruler of the islands, has been poisoned in an assassination attempt, but who is the culprit? And what are their motives? Lowarn's sister, Sirona, begs Fidelma to investigate the case, while Eadulf uses his medical skills to tend to the dying king.

Embroiled in a dark world of murder, suspicion and intolerance, Fidelma and Eadulf must discover if the islands are truly cursed by the Goddess Sulis, as the locals believe, or if warring monarchs from foreign lands are responsible for the islands' fate . . .
