About
In 2000, it was announced that Otsuichi would be writing a novel based on Part 4. The novel proved difficult to complete; in Kono Mystery ga Sugoi 2004, Otsuichi claimed to have written over 2000 pages, but had thrown them all out. Intent on writing a novel that lived up to the manga, it took him until 2007 to complete it.

The novel is about a normal day in Morioh, from the point of view of a new character (Takuma Hasumi). His stand is called The Book, has the appearance of a normal book, and possesses the power to record everything he sees or feels. Josuke and the rest of the Part IV heroes appear as antagonists.

Storyline
The story takes place in Morioh, in the year 2000. Three days before the end of winter break. Koichi and Rohan find a blood-stained cat outside a convenience store. They go searching for the cat's owner, and find a woman's strange-looking corpse inside the house. By using Heaven's Door, they find a clue: "a male student with red scratch marks under his arm." Over the span of 3 months, the curtain opens on this incident.
