The House that Jack Built

The house's unsettling vibe really stuck with me, but I'm curious whether the author based it on a real place or crafted it purely from imagination.

Some characters' choices felt layered and sometimes unsettling. I wonder if the author intentionally kept their motives mysterious to enhance the suspense.

The shifts between past and present added depth, but also kept me guessing about what was real. Was this structure planned from the start or did it develop during writing?
