Hello and welcome!

This is my third map so far. It is a mansion of a wealthy man with many secrets. Use the Owner's Key (a redstone torch) to find the secret doors that lead into odd places and uncover all the mysteries. Find out what he was doing with his money and where he was getting it from.
The secrets will not be revealed by the images.
Hint: Place the redstone torch on floor tiles that don't match the surrounding ones.

(If you have any ideas on what should I do next, leave it in the comments!)
