Hijos de Caín. Un thriller de la Transición española

A fast-paced thriller set in the years of the Spanish Transition, showing its lesser-known aspects.
Through Pinacho and Carlota, two intelligence agents who meet up again in the course of an investigation, we are drawn into a story in which what begins as a simple pursuit becomes one of intrigue and murder with it's origins in the Transition years. And this past must be relived in order to solve the present-day murders.
A mole who infiltrates ETA, spies, an ETA commando, an anti-terrorist death squad survivor, army personnel involved in a coup... a highly combustible mix when you get too close.
The main characters discover that they each have a particular interest in part of the story. How much must be remembered and how much left forgotten. A team who that helps them decide when they have to go their separate ways.
