INSPECTOR MONTALBANO 11 : THE WINGS OF THE SPHINX - Picador

Things are not going well for Inspector Salvo Montalbano. His long-distance relationship with Livia is on the rocks, he feels himself getting even older and he's growing tired of the violence in his job.

Then the dead body of a young woman is found. Her identity is at first unknown; a tattoo of a sphinx moth on her left shoulder links her with three other girls bearing the same mark. Victims of an underworld sex trade, these girls have been rescued by a Catholic charity organization. The problem is they can't help Montalbano with his enquiries. They are all missing?
