After London (1885), can be seen as an early example of "post-apocalyptic fiction": after some sudden and unspecified catastrophe has depopulated England, the countryside reverts to nature, and the few survivors to a quasi-medieval way of life. The book has two parts. The first, "The Relapse into Barbarism", is the account by some later historian of the fall of civilisation and its consequences, with a loving description of nature reclaiming England: fields becoming overrun by forest, domesticated animals running wild, roads and towns becoming overgrown, the hated London reverting to lake and poisonous swampland. The second part, "Wild England", is largely a straightforward adventure set many years later in the wild landscape and society (here too Jefferies was setting an example for the genre); but the opening section, despite some improbabilities, has been much admired for its rigour and compelling narrative. Critics dissatisfied with the second part often make an exception of chapters 22-4, which go beyond recreation of a medieval world to give a disturbing and surreal description of the site of the fallen city. Jefferies' interest in catastrophes predates After London: two short unpublished pieces from the 1870s describe social collapse after London is paralysed by freak winter conditions. In the better achieved of these, the narrator is a future historian piecing the story together from surviving accounts. The fantasy of the second part also has a predecessor in a short work, The Rise of Maximin, Emperor of the Occident, serialised in The New Monthly Magazine in 1876, in this case an adventure set in a remote and imaginary past. Although the society that Jefferies depicts after the fall of London is an unpleasant one, with oppressive petty tyrants at war with each other, and insecurity and injustice for the poor, it still served as an inspiration for William Morris's utopian News from Nowhere (1890). In a letter of 1885, he writes of his reaction to After London: "absurd hopes curled around my heart as I read it." Wikipedia
