In the water tank of a hotel in Los Angeles floats the body of a missing student. While on vacation, a man from Northern Germany suddenly feels pursued and disappears without a trace the next day. A mother takes her own life out of the blue and writes in her farewell letter that no one will find her little son Timothy - not even his own father. Three stories, three tragedies. But what has happened? The police are in the dark in all these cases. Julian Hannes recounts in "The World is Evil" 15 true, unsolved criminal cases from around the world that will keep young and perhaps even experienced crime fans awake at night. They are thrilling, mysterious, and above all, truly happened. The author researched the stories, followed their leads, and comments on them in his book in the same compelling manner.
