Nancy Drew Guides:
I'm on that puzzle with the gravestone map on the back of that paper... I found the stones with the names on the paper and... What to do next?
So there is an answer! The whole map is super misleading, you're not looking for AW's grave, you're actually looking for a box with a cypher in it which is covered by the brush on the floor under I believe cromley (cromwell) can't remeber the actual name. Its the one that on the left side of the gate when you're facing the exit to the graveyard into the square! It's kind of set back a little bit. Hope that helps a bit more. Again, sadly the whole thing is kinda misleading like most of the puzzles/directions in this game (what little there are) on here.
