"Mystification" by Edgar Poe is a classic work of American literature, which is considered the first detective novel in world literature. The main character of this mysterious story, C. August Eppenain, tells about his impression of the ingenious disguise and subterfuge during the commission of the crime. But will he be able to guess the most systematic secret that is hidden behind this very complicated life? Will he be able to see through the deception that apparently makes him doubt and lose faith in his abilities? Only the intersection of gigantic forces, which have permeated the hero's life without honor, help to understand that only a combination of intelligence and intuition can save him from complete decline.
