After a charity event in a posh hotel on Lake Zurich, the host of the evening is found murdered in his suite. Just a few days later, a top entrepreneur is found dead, tied to his rowing boat at the bottom of Lake Zurich. Both corpses have special features that point to a crime by the Ndragetha and put the Zurich police on high alert. When Dominic Mercier, one of the organizers of the charity event, receives a threatening letter, the investigation becomes a race against time. How can you protect Zurich's haute volée, which is obviously the focus of the attacks? What do the victims have in common? Is this all related to the charity convention? When Isabel Grandjean investigates the money dealings with a mafia sleuth, she uncovers a money laundering network with clear links between the charity funds and the mafia. Meanwhile, Tessa Ott is following a different lead. This leads via a boxing club to an orphanage, whose director is also murdered a little later. Here, too, there are special traces on the corpse, which Tessa is the first to understand. Tessa becomes more and more convinced that personal motives are behind the murders. She begins to research the dark web and embarks on a path in her research that is taking a heavy toll on her emotionally.
