Good Manners of the Nightingale Robber

Violinist Alla Fedina came to Max Wolf's detective agency. Barely hiding her anxiety, she admitted that she was very afraid for her life because someone was trying to poison her. It turns out that after Fedina's concert, a cake was handed to her backstage. The cleaner ended up tasting it and… instantly died. And here's what's interesting: the cake was handed by a young woman who introduced herself as the daughter of Vera Aramakina – a long-time fan and loyal admirer of Fedina. But why didn't Vera bring sweets to her idol herself? Because she recently passed away… The frightened violinist begs Max and Yevlampiya to find this girl. And to find out: did Aramakina even have a daughter?
