Saint Petersburg, 1888. A famous writer—and, on top of that, a hardened skeptic—Nicolas Wright receives an unusual request. The head of the postal service tells him about a strange photo studio where he was recently photographed with the spirit of his late wife, and asks him to investigate: is there truly some mysticism involved, or is it all a vile deception? Now Nicholas will need all his skepticism to uncover the truth and not doubt his own beliefs along the path to solving the mystery of the mystic photographs.
