***SPOILERS*** DO NOT READ IF YOU'D LIKE TO FIND THEM ON YOUR OWN!
1. Graveyard - Look at the stones leading back into the Mansion
2. Ballroom - Look on the little table in the corner near the chair.
3. Conservatory - The light coming in shining onto the piano
4. Mausoleum - (This is the toughest) I believe once again...look at the stones leading into the room (a shadow on one of the stones)
5. Library - Stone tile in floor and candles on table
6. Attic - One near arrow...and the other is on the crate across the room from the arrow (near the door)
7. Foyer - Stone tile
8. Portrait Chamber - Tile in floor
9. Seance Room - Pattern in corner of rug (near door to Portrait Chamber)
