Kraken must navigate the "silence" of a community that protects its own secrets. He discovers that the killer is using the city’s own architecture—the way the wind whistles through the Old Quarter—to signal the next location. In a race against time, Kraken realizes the final "sacrifice" isn't a person, but the city's history itself. Atmosphere & Style

A slow-burn, "Nordic Noir" style thriller set in a warm, historic Spanish landscape.

Inspector Unai "Kraken" López de Ayala is a criminal profiler obsessed with the symmetry of the crimes. He is haunted by the fact that the man originally convicted for similar murders twenty years ago, a brilliant archaeologist named Tasio, is still behind bars.
