Lisbon Noir (Season 1)

A Spanish diplomat falls from the top of the Aqueduct. The police investigate with the help of a Spanish inspector. It quickly becomes clear that there is a serial killer in Lisbon, inspired by the legendary "Aqueduct Killer" of the 19th century: Diego Alves. When the police seem close to solving the case, a twist reveals that the psychopath is still at large, this time driven by personal revenge.
