After a charity event in a posh hotel on Lake Zurich, the evening's host is found murdered in his suite. Just a few days later, a top entrepreneur was found dead, tied to his rowing boat at the bottom of Lake Zurich. Both bodies have special features that point to a crime by Ndragetha and that put the Zurich police on high alert.

When Dominic Mercier, one of the organizers of the charity event, receives a threatening letter, the investigation turns into a race against time. When Isabel Grandjean examines the financial transactions with a mafia expert, she discovers a money laundering network that shows clear connections 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 short time later. Here, too, there are special traces on the corpse, which Tessa now knows how to interpret. Tessa is increasingly convinced that personal motives underlie the murders.

However, the fact that her careerist superior Wegenast, who is well connected and working on her promotion, wants to take advantage of the results of the investigation turns out to be a risky move in a political game...
