Tomás Nevinson has left the secret service and returned to his old job working in the British Embassy in Madrid. Assumed dead by his wife Berta, Tomás attempts to resume his previous life and heal from his psychological wounds. But when he is contacted by his old boss, Bertram Tupra, Nevinson reluctantly becomes involved in a plan to locate and eliminate a woman believed to have helped orchestrate the 1987 Hipercor bombing. Detonated by the ETA, a Basque separatist group, the bomb killed 21 people and injured 45. Full of mesmerising intrigue, this novel offers a deep reflection into the moral dilemma of whether the killing of a presumed criminal can be justified.
