The old ditty got it wrong: it should have been ‘Maybe it’s because I’m not a Londoner that I love London so’. The capital’s biggest fans, I tend to find, are those who weren’t born there, and Emily Chappell is yet another example. Originally from Wales, she has written more than just an engaging account of her work as a London cycle courier: she has chronicled the way in which the capital provides a home for those who don’t fit in elsewhere.
