In essence, this story is about how a certain person was searching his bookshelf for something to read and in the end found a book, which turned out to be the source, from which it is possible to obtain absolutely any kind of information about absolutely any person. Meaning, information to the smallest particulars and details about what his or her qualities of personality are, how he or she lives, what he or she really wants to achieve, what he or she hides, and much more. And, it does not matter, if the subject is some person, who lived in the distant past or lives in the present or someone, who will live in the future. Since, as it turned out later on, this literary monument is nothing other than the catalog of human population. In other words, the encyclopedia of Homo Sapiens; in essence, the same as encyclopedias, reference books for specialists, which contain complete information about representatives of a particular subspecies of animals, plants, etc.

Although at some point, the course of this story turned banal: bad guys from security services, intelligence services, politics decided to not only use this source of knowledge for their dirty deeds, but also to appropriate it solely for their personal use. And, the way they tried to do this is also banal: by physically destroying the author of discovery of the Catalog of human population and all of his colleagues. However, the ending of this story makes it stand out from the category of ordinary spy stories.
