Many blocks in the town of Richmond-on-Thames are bisected by narrow footpaths just wide enough for two people to pass each other. I imagine they are medieval and therefore older than most of the buildings. Unless you know the town well it’s risky to take them, because some are dead ends and you have to double back, but I find them more intriguing and peculiar than the shopping streets; you never know who or what you will meet. This one took me through a pretty little churchyard, where I found a grumpy Dickensian sign. There was no bank to be seen.
