The Mystery of the 99 Steps

I wonder what sparked the idea for this particular puzzle and how she decided to make it central to the plot. It feels like a clever detail that really drives the adventure.

The story balances mystery and action nicely, but I’m curious if others felt it was just the right speed or if some parts dragged for them.

Their teamwork seemed key to solving the puzzle. Do you think the story emphasizes friendship as much as the mystery itself?
