On a hot July morning on Sweden-s idyllic vacation island of Sandhamn, a man takes his dog for a walk and makes a gruesome discovery: a body, tangled in fishing net, has washed ashore.
Police detective Thomas Andreasson is the first to arrive on the scene. Before long, he has identified the deceased as Krister Berggren, a bachelor from the mainland who has been missing for months. All signs point to an accident-until another brutalized corpse is found at the local bed-and-breakfast. But this time it is Berggren-s cousin, whom Thomas interviewed in Stockholm just days before.
As the island-s residents reel from the news, Thomas turns to his childhood friend, local lawyer Nora Linde. Together, they attempt to unravel the riddles left behind by these two mysterious outsiders-while trying to make sense of the difficult twists their own lives have taken since the shared summer days of their youth.
