The mayor of Barcelona is being blackmailed. A sex tape from her student days – one she never knew existed. The price: 300,000 euros and her immediate resignation.

A political chameleon who swept to power on a populist wave, she has her enemies. Nor can she trust those closest to her. Both her ex-husband and her deputy would profit from her fall.

Melchor Marín, living a quiet life in Terra Alta, is tempted back to Barcelona to work the case. But what seemed a simple matter has its roots in far more serious and disturbing crimes. With the mayor on the verge of capitulation, a shock revelation changes everything – not least the course of Melchor’s life.

At long last, his heart’s dark desire is in his grasp.
