Puerto escondido

When Oliver, a young Londoner, inherits a colonial mansion on the coast of Cantabria, he imagines a peaceful escape from a recent loss. But during renovations, a horrifying discovery is made in the basement: the walled-up body of a baby, buried with an object that makes no sense for its time. This grim finding is only the beginning, as a series of violent murders begins to plague the serene coastal towns, each victim linked by baffling forensic evidence that defies easy explanation. The local Civil Guard is stumped, and Oliver finds himself drawn into the heart of a dangerous investigation.

The key to the present-day killings seems to lie in a dark tragedy from the past, a story of passion, ambition, and betrayal rooted in the Spanish Civil War. As Oliver and the investigators race against time to find the killer, they uncover a story that has remained hidden for decades. The tranquil beauty of the seaside setting conceals a terrible secret, and understanding the crimes of the past is the only way to stop the bloodshed that has erupted in the present.
