Main Story[]
When Mr. Inference and Lady Truth walk into Castle Zinaida, the fate of everyone seems to be pushed forward by an unseen force. As the incomplete novel reveals itself before all the attendees of the funeral, their fate is rewritten just as the story unfolds. And Zinaida remains watching silently the entire time. Maybe she arranged everything from the very beginning: who is the protagonist and who is a prisoner of fate...
