Detective Kate Bowen is accustomed to dealing with difficult men as she leads Dublin's Surveillance and Intelligence Unit and in disastrous love life. But when her team discover ex-IRA stirrings and chatter of an alliance between a rogue group and a Paris-based militant Islamic cell, Kate unearths a tangled conspiracy hiding a vengeful Irish terrorist's plot. Her investigation leads into a warren of France's disenfranchised Muslim youth, a bombing at the BBC Proms, and sniping between intelligence agencies that threaten to derail the case. And Kate's boyfriend, the seductive Charlie, isn't what he seems either. Not by a long shot. A police procedural with a gritty female sleuth pitted against an international alliance of the world's worst terrorists, a pompous MI5 Section Chief seeking glory with innocents being tortured and slaughtered along the blood strewn way.
