“You are suspected. Dangerous for you. Prove that the suspicions are groundless." The hero of the novel receives such a note, written on a quarter sheet of paper. And what do these words mean, what do they promise, what are they forcing him to do? He is completely law-abiding and does not violate the principles. True, he lives in a strange city, where everything is subject to the immutable rules of the secret and formidable service of sterility. A light veil of fantasy covers the narrative, in the center of which is the personal drama of the hero. His receipt of a ridiculous note at first looks like an unpleasant misunderstanding, but it divides his life into “before” and “after”. The further the novel progresses, the faster it goes – the author undoubtedly masters the techniques of detective storytelling. The novel is written with stylistic grace and metaphorical sophistication.
