Sleeping as much as you want, lazing in the sun, and eating until your stomach hurts – that's how summer vacations in Crete should be. But a private detective like Klooz is always on alert. And so it doesn't take long for him to get entangled in a case that brings him face to face with a mystery that seems unsolvable. Fish have disappeared from a fishing spot near the town. Did they leave? Or maybe not? Maybe it's not the fish's fault but the people's? To solve the mystery, Klooz will have to dive into the deep blue waters himself.
