Addison Mason had no enemies. Everyone loved him, yet he's been murdered. Marco is again teamed with Detective Alberto Flores of the Malaga police. They are tasked with investigating the death of Addison, the owner of a new cultural museum in the city. Addison is murdered on the museum's opening night, when a famous painting from the fifteenth century was to be unveiled. Marco and Flores must determine whether there is a link between the murder of the curator and the valuable, famous painting, which had been lost since the Spanish Civil War. The search for answers reaches Spain, the UK, and Morocco. The Chief of Police, the Mayor, and the town dignitaries of Vivirrambla are relying on the unlikely pair to solve the case, or both their careers could be on the line.
