Room 13 and Other Ghost Stories

I read Room13 and Other Ghost Stories.

This book has some stories. Some stories are very interesting for me, but THE MAZE is not interesting.

I can't understand to read THE MAZE. People couldn't go out the maze. There are some creature in maze. Why are people go out in maze? Ledy Wardrop puts her handkerchief on a tree on the right-hand side of the path. After that she have come this way again. But her handkerchief is on the left-hand side. I couldn't understand this reason.

This story is very difficult to understand its contents.
