Het huis op de rots

The mysterious house adds so much atmosphere—I'm curious whether the author based it on a real place or envisioned it entirely.

The story had such a great build-up, but those middle parts felt a bit slower. Was that intentional to build suspense or just the flow of the story?

Their camaraderie felt genuine and a bit old-fashioned. I wonder what the authors wanted to emphasize about friendship at that age.
