On first turning on to Myddelton Passage it looks like a typical London road. Houses along one side stand opposite a brick wall, that, although old, looks rather plain.
It is not until you begin to walk along the path that you will notice etchings in the bricks. Random numbers, initials and letters can soon be seen. Although sporadic, at first, they begin to fill entire areas of the wall.
Could they be some form of code or something else, entirely?
