Мокрое дело водяного

Dasha Vasilieva and Colonel Degtyarev were invited to the anniversary by their good friend Fyodor Mukhin. The guests celebrated lavishly, eating, drinking, having fun, and enjoying a concert featuring stars of the world stage. Mukhin, a wealthy man, is not... at all stingy; he spends money easily. He is a good person, treating Elena, his wife Svetlana's sister, very well. He loves Nina, the daughter of his sister-in-law from her first unsuccessful marriage, and spares no expense for her or his daughter Katya. A happy, wealthy, and successful family. During the celebration, Svetlana starts feeling unwell. So unwell that she is quickly taken to the hospital. There it turns out that the woman was poisoned! And it is clearly someone from their circle. Fyodor categorically does not want to involve the police and asks Degtyarev, who now owns a detective agency, to find the criminal. Well, how can he manage without Dasha Vasilieva? And of course, Dasha will find the perpetrator, even if it means she has to turn into... an electrician!
