When I was trying to find a form for my book, I did wonder whether I could use something like "In search of the perfect walk." But I abandoned that idea because in the end I thought there was probably no such thing as a perfect walk, and even if there were it would be completely different for each individual person.
Even so, as I've publicized the book, people have been asking me what my favorite walk is, and whether I could recommend a walk for them to do, and I've done my best to come up with something intelligent, even while admitting that questions like that usually make my mind go completely blank.
Then I got a call from Martin Krasnik, a Danish journalist based in London. He wanted to interview me for his newspaper, but before he did that, could I recommend a good long walk he might do in London. While we talked on the phone I dug out a map, looked at it, and started making random suggestions. Yes, he might start in Oxford Street, say by the 100 Club
