A royal death. A secret investigation. A case for Sherlock Holmes.
13th June 1886. Two dead bodies are dragged out of Lake Würm: a king — and his psychiatrist. Officially an accident, unofficially a mystery. What hardly anybody knew: Sherlock Holmes personally investigated the case. His findings remained under lock and key — until now.
