The marked location should take you down a lane with a sign for Menderhall cemetery, follow that rather long lane all the way to its end at the cemetery itself, as you pull into the graveyard you will see 2 raised concrete border rectangles in the center of this small graveyard, go to the one with two trees in it and a obilisk shaped grave marked Mosey. Look within the tree that is more to the north of the 2.
