The body of a young woman who died with a smile on her lips appears in a square in the Gothic quarter of Barcelona. Agent Elsa Giralt, questioned since her partner was quadriplegic in a gunfight, will have to solve it if she doesn’t want her career, and perhaps her life, to go down the drain. But what appears to be another crime will become something much more important and convoluted when Dragan Jelusic, the most wanted member of the most audacious jewellery-thieving gang on the planet, the Pink Panthers, enters the scene.
