‘As far as books are concerned, I find life no help at all. Books grow out of other books.’ So said the great Ivy Compton-Burnett, and her comment is at least partly pertinent in relation to Lloyd Jones’s luminous Mister Pip, trailing as it does clouds of Dickensian glory. Increasingly, there seems to be a sub-genre of novels that have their roots in other novels. Some of these are vile, like Emma Tennant’s vulgarly opportunist Pemberley Revisited: or Pride and Prejudice Continued (2005) and Emma in Love (1996), which traduce two great novels. Others work more evocatively, like Jean Rhys’s Wide Sargasso Sea (1966), a post-colonial reimagining of Jane Eyre from the point of view of the madwoman in the attic, or Peter Carey’s Jack Maggs (1997), which, with elliptic brilliance, re-situates Magwitch at the heart of the narrative of Great Expectations (1860–61).
