Autumn, AD 672. While out walking, Abbot Brocc was shocked to encounter the sinister apparition of a young woman, cloaked entirely in grey, who foretold his impending death. Dismissing the soothsayer's words, Brocc nevertheless felt concerned enough to ask for Sister Fidelma's advice on the matter. But by the time Fidelma and her companions arrive at the remote abbey of Dair Inis, Brocc has been found dead in the abbey's sweat house - as the mysterious prophetess had predicted. Plunged into a world of uncertainty, where believers of the Old and New Faiths are violently opposed, Fidelma, Eadulf and Dego embark on a journey fraught with danger, in a puzzling and perilous quest for the truth behind Brocc's murder . . . Sister Fidelma returns in Prophet of Blood, the thirty-fifth Celtic mystery by Peter Tremayne, acclaimed author of Death of a Heretic, The House of Death, and The Shapeshifter's Lair. If you love Ellis Peters, you'll be gripped by Prophet of Blood and the whole Sister Fidelma series.
