### Secrets of Investigation 10 (2011)

District IC Investigative Committee of Russia headed by Nikolai Filonov (Senior Advisor of Justice) would long have turned into the organization for the collection of statistical crime related data, if not for Maria Shvetsova and her colleagues – experienced homicide detectives Vinokurov & Kurochkin. Maria is not afraid to take the initiative and, in spite of irritation of Vinokourov, she always prefers to go to the scene herself in order to interview witnesses and gather evidence. And often, it is only she whose watchful eye manages to catch the details that eventually lead to solving crimes. Without her participation of the strange death of the director of thriving "Autlink" would have been qualified as a simple accident. However demanding Shvetsova insists on forensic expertise and establishes the true cause of death of Nikanorov. Shvetsova used to always trust her sensitive intuition that helps her, even if the mere facts are not enough. Thus, having begun the investigation of the murder of the owner of the collection of antique coins Florinskaya – she pretty quickly discovers that the prime suspect, whose "candidacy" is insistently being suggested to her by the relatives and friends of the deceased, has actually nothing to do with this crime. Maria Shevtsova always tries to see into the case from different sides, and then the true motives of the murder come to the surface. In some cases, the work of the investigator comes to scrutinizing all evidence collected at the crime scene; and sometimes becomes a real puzzle. However, by restoring the true picture of the crime, Maria manages not only to find the culprits, but also to prevent a new crime. Meanwhile, Maria's boss Nikolai Filonov remains concerned solely with his own career growth. For the sake of promotion he is ready to pull the brakes on any "uncomfortable" case. A principled and stubborn nature of Shevtsova's may cause considerable inconveniences to such superior; so each case for Maria Sergeevna may be the last.
