After Franco's victory, the young republican doctor Guillermo García is able to continue living in Madrid, thanks to a false identity organised for him by his best friend, a diplomat whose life Guillermo saved in 1937 and who in 1946 comes home on a secret and dangerous mission: to infiltrate the secret organisation led by Clara Stauffer in Madrid facilitating the escape of criminals from the Third Reich. While Guillermo allows himself to be recruited, a Spanish boxer who fought in the last defence of Berlin as a volunteer for the SS, struggles to get by in Germany, unaware that someone means to steal his identity to escape to Argentina. Thriller and spy novel, this is the author's paciest, most ambitious and most international story yet, one in which she draws on real events from WWII to create characters who share the fate of Spain and Argentina, and the start of the Cold War.
