"Nothing is more challenging, nothing less sentimental, than the invitation of spirit to become who we are and not who we think we ought to be."
Thomas Moore
If I stumbled(no pun intended) on one of these in my house, I would bail in a heartbeat. Because I've seen enough movies to know only disaster will follow. Either:
A)The guy who took the rap for the robbery will show up looking for the money he stashed there-soon to be followed by the rest of the gang who've been waiting for him to to just that.
B)Somebody got waxed in the secret room and their restless ghost has been waiting to be discovered so they can unleash their terrible vengeance.
