You are looking for a seven letter word.
Using A=1, B=2 etc, use this word to plot the coordinates of the virtual stage, and go there.
N 50° 48. (5th letter + 1st letter - 2nd letter - 6th letter) (7th letter - 5th letter + 1st letter) (4th letter - 5th letter - 1st letter)
W 000° 23. (4th letter - 7th letter) (2nd letter - 6th letter) (1st letter + 2nd letter)
When at the virtual stage (you should know if you've got it right! - things will make sense
and the play on words is intentional!), please make sure you are standing on the north side of the road and find the following information:
A = number of words on the roadsign in front of you
Then walk 15 paces to the west, and find a small metal rectangle laid in a larger concrete rectangle in the pavement.
B = single digit on the right hand side of the metal rectangle
C = number of letters in the name of the house directly behind you (north side of the road). It starts with a P.
Then walk another 15 paces to the west.
D = number of letters in the first word of the cottage (north side of the road).
Now plot the final coordinates, which are only a short walk away.
N 50° 48. (B+C-D) (B-A-A) (C-A)
W 000° 23. (D-B) (C-D) (D-A)
