Welcome to the District of the Secret Lakes—a muddy gray place where gloomy calm reigns. Stay away from dark backstreets, because in them you can run into pale-faced fanatics whispering prayers to an unknown god, stray children, berry addicts, and elderly people maimed by mutation, covered with whitish fish scales. Junior detective of the Marvan Katan agency, Marvan Katan, is forced to take her mentor’s position in order to continue keeping order in the district. At first, nothing happens that would be worth paying attention to… Until destructive mass drunken brawls begin, setting off a chain of terrifying events. When the fire of aggression is finally put out, the public is shocked by the news: Igor Kongerman, one of the three heads of the Department, has been found dead. The man has no fingers on his hands, his tongue has been roughly torn from his mouth, and in place of his eyes there are two dark openings.
