Tired Prince Ivan can turn into Serpent Gorynych. But private detective Podushkin won’t start breathing fire—even if a man named Bob Solnechnolaskovich appears and offers Ivan Pavlovich to advertise the firm “Podushkin-Odeyalkin.” Before the detective manages to get rid of the annoying visitor, neighbor Irene arrives and asks him to talk to the daughter of her acquaintances, Katya Voykova. The girl’s father recently died; nothing suspicious was found in the death of Alexey Voykov, but Ekaterina believes the businessman was murdered. Irene asks Podushkin to conduct an investigation “for show,” to calm the frantic daughter. Delicate Vanya couldn’t refuse, promising Katya he’ll find the killer of her father.
And it turns out her suspicions aren’t all that absurd. But the moment Podushkin finished this toughest investigation, Bob Solnechnolaskovich showed up again and turned all his neat conclusions into a pile of wreckage.
