If you haven’t visited, mine is a typical south-west English coastal town: Londoners escape here to live, old people remain here to die. It used to be a one-horse town, but the horse now lets his stable on Airbnb for £250 a night during holiday season – you know the kind of place. It has only a small residential population and everyone, but everyone, is connected somehow. Westmouth is not so much Six Degrees of Separation as Half an Inch from Incest.
