The Water's Edge

"A married couple, Reinhardt and Kristine, are out for a Sunday walk when they discover the body of a boy and see the figure of a man limping away. They alert the police, but not before Reinhardt kneels down and takes photographs of the dead child with his cell phone. Inspectors Konrad and Jakob begin to make inquiries in the little town of Solberglia. But then another boy disappears, and an explanation seems more remote than ever. Meanwhile, their marriage starts to unravel as Reinhardt becomes obsessed with the tragic events and his own part in them"--Publisher's web site.
