Mist & the Maiden [Russian]

A young man's corpse appears in a forest on the island of La Gomera. The case closes with the accusation of a local police officer who is exonerated in a later judgment. Three years later, Sergeant Bevilaqua and his assistant, Corporal Chamorro, are sent to the island to revive the investigation, accompanied by Corporal Anglada, who was the last person to see the young man alive.
