MADRID, 1982. Comandante Leopoldo Guzman has decided it is time to disappear. Franco is in his grave and there's no place in the new order for the one-time head of the dead dictator's secret police. But first Guzman needs money. Luckily, blackmail has always come easily to him - after all, he knows where the bodies are. And so he should. He buried them. MADRID, 2010. Fifteen tangled corpses in a disused mine, three bound skeletons in a sealed cellar - a trail of dead that has led forensic investigator Ana Maria Galindez to one Comandante Leopoldo Guzman. Guzman himself disappeared decades ago but she fears his toxic legacy lives on. Her investigation has revealed a darkness at the heart of Spain, a conspiracy born amid the corruption and deprivation of Franco's dictatorship, a conspiracy that after decades in the shadows, is finally ready to bloom.
