It is Holy Week in Seville and the heat is rising. A murderer is on the loose and visiting academic Maria Gutierrez can see something in his ways that the police are missing. But her insight does nothing to help her popularity in the force – and draws her to the attention of the killer.

The Angel Brothers, two controversial modern artists, are found dead in a killing that emulates a famous painting, and an old lady remembers the atrocities of the Civil War. Maria was supposed to be an observer to the police investigation. But her own past in the city soon puts her one step ahead of the cops... And in the killer's sights.
