Book of Riddles

The Book of Riddles is a book found by Luigi in the Study of the mansion. One riddle can be read by Luigi. It describes how if one keeps away from a mystery, they should go back and look at it from a different point of view. This is a great way to help Luigi defeat Neville, as it is provides a hint to capturing him.

Riddle
"Mysteries appear wherever people turn... ...but turning away from them solves nothing. Instead of turning away, turn to the side and look at the mystery from a different view. A way will surely open."
