Yes, the guide/directions are the arrows on the bottom right of the map - they're supposed to correspond to the graveyard path starting from the red arrow on the left which represents the entrance to the graveyard. So (from memory), entering at the red arrow, at the first junction take a left, then at the next take a right, then at the next a left, then head across the courtyard in the middle (possibly confusing), then take a right, then a left, then right, then a right. This probably is one of the weaker puzzles, I might need to think about altering it slightly in a patch - it can be brute forced but that's not necessarily a good thing.
