The third weird note --

"A flower is a joy when it thrives"

-- has a section that tells you to "Place a flower where she stands." Huh?

After you get into the crypt and Harper leaves --

How do I get Harper to leave?

-- take one of the flowers from the table under the stained glass window. Now you need to find a statue of a standing woman with at least one empty hand.

Go back out into the cemetery, and there she is, the one at the top of the stairs. Stand in front of her and place the flower in her hand --

-- and it drops out, and nothing else happens. Hmm. But wait, what was the second part of the message?

It says, "Away and back to earn her trust." So go back in the crypt, then come back out and look at the statue again.

It's very easy to miss, but if you stand on the path coming from the crypt and look at the base of the statue, you can just see a piece of paper that wasn't there before.

Still can't see it? Stand so that the statue is at the left of the screen and you're overlooking the cemetery, with Wade at the left and the gates at the middle right. Move the mouse slowly around the statue pedestal until it turns into a hand, and there it is.
