A drowned young woman is discovered on an abandoned pleasure boat drifting by the Stockholm archipelago---strangely, her clothes are dry. The next day in Stockholm, a man turns up dead, hanging from a lamp hook inside his completely bare apartment---but how could he have hung himself with no furniture to climb upon? As Detective Inspector Joona Linna begins to piece together the two mysteries, he discovers that they are a mere prelude to a dizzying and dangerous course of events.
