Addictive Books

On a bleak lava field just outside Reykjavik stands the Gallows Rock -once a place of execution, now tourist attraction. Until this morning, when a man was found hanging from it. The nail embedded in his chest proves it wasn't suicide. When the police go to his flat, a further puzzle awaits: a four-year-old boy has been left there. He doesn't seem to have any link with the victim.
