The first picture shows the entrance to the mansion. Nothing special there. Same with picture 2, which is one of the paintings in the parlor.
Picture 3 shows an odd pile of dirt, but it looks familiar -- and as it happens, it's a pile of dirt here under the porch. But how to dig it up?
In the tool room, there's a trowel hanging off of a pillar in the middle of the room. That'll do the trick.
How do I open the box under the dirt?
Picture 4 shows a coffin with an odd yellow design on the top. You'll find out more about this once you get into the crypt.
Picture 5 shows a close-up of the wine barrels in the cellar -- but there's something in the picture you didn't see before.
Like that handle. Wonder what would happen if you yanked on it?
Behind the Barrels
Picture 5 shows a picture of some sort on one of the pillars. After you get out of here, go look at the pillar (it's the one next to the porch swing) and see what you see.
Picture 6 is the odd stone with a T on it near the entrance, the one where you found the scavenger hunt page. But it looks very different than it did when you were there.
After you get out, go pull the weeds aside to find --
-- the Ruins, the burned-out shell of the building where Charlotte was killed. Gasp!
