Browsing in a second-hand bookshop on Charing Cross Road in the spring of 2004, I came across a copy of History and the Early English Novel by Robert Mayer. I opened it up and loose papers tumbled out. Turning the book’s pages, I saw hundreds of annotations pencilled in the margins: shaky lines and ringed numbers and then, across the endleaves and inside back cover, a thick scrawl of largely illegible notes: page numbers, cross-references, summaries, words circled furiously or underlined – ‘21. Facts’; ‘135. Origins of novel’; ‘143-4. Cromwell, Defoe’. What looks like ‘48-9. Milton’s lust’ is probably ‘Milton’s hist[ory]’. The inside cover has an elegantly looping signature: ‘Christopher Hill/1997/7’. I put the loose papers back and handed over £15. Then I put the book on my bookshelf and forgot about it for nine years.
