Tatiana Shakhmatova's action — packed novels are the only ones of their kind, because an expert philologist deals with the investigation of crimes in them with the help of his own original methodology. Reading between the lines, the ability to determine the personal characteristics of the author from the text, restoring the subtext and hidden information-this is the arsenal of a new type of detective. The word is not a sparrow, and a real philologist can identify the criminal by suffixes and commas, as Sherlock Holmes found the killer by tobacco ash.
