per 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!
