Some mysteries are better left unsolved. Colonel Degteryaev, who immediately after retiring opened his detective agency, clearly begins to understand this phrase. Having hired an assistant Dasha Vasilyeva, he takes up the first case together with her. Recently, Zinaida Lvovna Komarova has been terrorized by an unknown woman on the phone, posing as her long-missing granddaughter Varya.
Of course, an inspired couple of heroes are ready to understand the situation, but what they managed to find out… In general, some mysteries really should remain unsolved.
