After the folder and client disappeared, someone ransacked Nadezhda's apartment. She turned to her friend and lawyer, Mark, for help. The next day, Nadezhda made a new acquaintance, the restaurateur Denis, and that night, burglars broke into the tailor's shop and killed the security guard, Vasily. From a casual acquaintance, an elderly woman named Ulyana, Nadezhda learned that in 1926, a young woman named Zosya Dombrovskaya had been murdered in the mansion where the tailor's shop was located.
