About the book: year / There is less content here than in its predecessor, but it is there. Elena’s subordinates (“first group”) are participating in a new case, this time it no longer mentioned in passing. Sergius's great-grandfather, in the hope of returning his failed bride, turned to a detective for help. An uninvited guest has appeared in a district center that no one needs. Sergius, at his own peril and risk, watched a feature film about the events of the previous books. And of course, he again warns: the constant song parodies have tortured.
