Summoned by her brother, the king, when the body of a murdered noble is discovered near Cashel in 670 Ireland, Fidelma and her companion, Eadulf, follow clues linking the victim to an uprising under the leadership of a religious fanatic When a murdered corpse of an unknown young noble is discovered, Fidelma of Cashel is brought in to investigate, in Peter Tremayne's The Seventh TrumpetIreland, AD 670. When the body of a murdered young noble is discovered not far from Cashel, the King calls upon his sister, Fidelma, and her companion Eadulf to investigate. Fidelma, in addition to being the sister of the king, is a dailaigh-an advocate of the Brehon Law Courts-and has a particular talent for resolving the thorniest of mysteries. But this time, Fidelma and Eadulf have very little to work with-the only clue to the noble's identity is an emblem originating from the nearby kingdom of Laign. Could the murder be somehow related to the wave of violence erupting in the western lands of the kingdom? The turmoil there is being stirred up by an unknown fanatical figure who claims to have been summoned by "the seventh angel" to remove the "impure of faith." Fidelma and Eadulf, once again grappling with a tangled skein of murder and intrigue, must somehow learn what connects the dead noble, a murdered alcoholic priest, and an abbot who has turned his monastery into a military fortress. When it appears that things cannot get more complex, Fidelma herself is abducted, and Eadulf must rescue her before the mystery can be solved.
