Simon Barnes opens with a presumably true idea, that we are all in search of our own versions of paradise — a special place presented here as the sacred ‘combe’ of the title, being a word with Celtic origins that describes a steep hollow or hidden valley. These paradises might be real or imagined, exist only in memory, or live in fiction like Narnia or Robin Hood’s forest; they can be unattainable, beyond reach, or ruined, like Eden.
