La química del odio

For Chief Inspector Ana Arén, the battle is far from over. Six months after surviving the case that nearly destroyed her, she returns to duty, fragile and demoralized. There is no gentle re-entry into her profession; on her first day back, she is assigned to a new homicide team and thrust into the center of a media firestorm. One of Spain's most famous and recognized women, the Duchess of Mediona, has been murdered, and the crime scene is a carefully constructed stage.

Now, Arén must navigate a labyrinth of secrets among the country's elite. Constantly questioned by a hostile superior and leading a team that does not yet trust her, she is in a race against time. The investigation forces her to confront not only the artifice of the crime but also the dark motivations that fuel extreme hatred. As the pressure mounts from all sides, Ana must determine what is real and what is performance before the past consumes the present entirely.
