The book by Pavel Pavlovich Kravchenko, a former investigator of the Department of Internal Affairs for Particularly Important Cases of the Crimean Region, will serve as an invaluable help for any person seeking answers to the basic questions of existence, the meaning of life, decency, morality and spirituality. It shows the selfless struggle of an individual for the ideals of morality and justice in society, not in words, but in deeds. The book once again demonstrates the possibility of defending one’s own point of view in the former Soviet Union, regardless of one’s position and place of work. The work consists of two parts. The first part is episodes of life lived (autobiography). The second part contains cases from investigative practice (essays and articles published in various media). The book is aimed at a wide range of readers.
