About Secrecy of the Investigation

Secrecy of the Investigation is a mystery and action & adventure TV series that premiered on Smotrim on September 1, 2000. It has 25 seasons and 430 episodes so far and is still airing new episodes. The latest episode, Season 25 Episode 16, aired on December 10, 2025.

In the center of the plot is a senior investigator named Masha Shvetsova and her male colleagues. The plot is the most vital, but, like in “Streets of Broken Lanterns,” it is seasoned with a fair amount of humor - otherwise, how can the audience (and the heroes) endure countless morgues, identifications and other “cute” charms of the investigative routine?
