Mystical-historical detective story. What is the gift of foreknowledge of death? Perhaps envious people will call you crazy, but a true detective will never neglect the details, and your words will help him solve the crime. Of course, the plot is not complete without adventures: wanderings along dangerous mountain paths and shootouts with mountaineers. The theme of Death and mysticism on the verge of reality, as well as an attempt to recreate the spirit of the era: the birth of the age of forensic science and secret investigation, the fashion for mystical phenomena, the conquest of the Caucasus. The chapter titles use phrases from the poem by Percy Bysshe Shelley (translation by V.V. Rogov)
