Stuck? Confused on where to go next? Here are some hints:

=I'm stuck on the first floor!
  There are two ways to get to the second floor, both of which you will have to find.
  One is a puzzle in the library. There will be a ladder up in a secret room.
  The other way up is in the Guest Room. Look very carefully!

=I can't find a way to the third floor!
  Check the 2nd floor Lobby very carefully.

=I have a basement key. Where is the basement?
  Backtrack back outside. There's a slot for the key near a small stone structure against the mansion.
