Based on the hit novel, this series follows a chilling mystery about a house designed for murder—which is now a live-action movie! I’ve always had a fascination with the occult; you might even call it my specialty. I’ve been brought in as a consultant on many supernatural and strange mysteries. But nothing could have prepared me for this house. It seemed so ordinary at first, except for that one room. It had no doors, no windows, and was tucked away, leaving anyone to think it was just a wall. I knew that there was something more to it. It shouldn’t be there, it shouldn’t exist, and yet… Just what is this house, and what dark secrets does it hold?

WHAT LIES BENEATH The deeper I dig into the mystery of these strange houses, the more disturbing things get. Miyae-san’s theories about the Saitama House were plenty chilling on their own, but with Kurihara’s help, I’ve come to realize she’s only scratched the surface of its secrets—literally. Why did it have a secret basement? And was it really used—as Kurihara suspects—as a morgue? Also adapted into a horror film called The Floor Plan!

THE THIRD HOUSE Yuzuki is not who she claimed to be. I now know that her sister lived in the Tokyo house, but this murder mystery is far from solved. In fact, it’s only getting stranger and more disturbing. After Yuzuki tells Kurihara and me about the tragedy that occurred just a week before her sister’s disappearance, I realize there’s only one path forward—we must visit the house where her cousin was murdered.

DARK FAMILY SECRETS As Yuzuki and I investigate the Katabuchi family home, our unease grows. What dark secrets has her family been hiding? The mysteries deepen, but at least one has been solved: the identity of You-chan’s murderer. Yet that is only the beginning of the strange, disturbing truth...
