Two corpses in a row? On Sandhamn, this island holiday paradise? It is impossible to believe...And yet it is true. The body of a mainland stranger washed ashore, entangled in fishing nets; he disappeared several months ago. Looks like an accident. But then a naked woman was found beaten to death in the hotel - this is the cousin of the deceased, whom the police had recently questioned in Stockholm in connection with the death of her cousin. Having survived a family tragedy and barely escaped from a nightmarish depression, Inspector Thomas Andreasson must find a connection between two deaths - after all, it cannot but exist... Why did alien relatives arrive on the island one after another? And who did they disturb so much with their visit?
