The Wings of the Sphinx

Things are not going well for Inspector 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... As his investigation progresses, it seems that not everyone wants Montalbano to discover what really lies behind the organisation's charitable facade.
