The lady did not hesitate to bring with her, under the guise of a family friend, the young actor Obodovsky, with whom she had a very clear relationship. This did not end well - the actress was killed right in the living room, shot from a revolver with a mother-of-pearl handle... The day before, Evgenia attended a party where the famous writer Ergolsky, at the request of those present, came up with how and why each of them could be killed. And someone took advantage of his plot in reality... None of the guests that evening had an obvious motive, and the investigation completely reached a dead end when its owner, the brilliant Baroness Amalia Korff, appeared at the “Water Lilies” estate and took up the investigation herself...
