Even if you've practically memorised the books, Wolf Hall still feels incomplete. Because it is. The third part of Mantel's trilogy, which details Cromwell's downfall, hasn't yet been published. Wolf Hall is a tragedy, but right now it concludes like a comedy (well, a comedy with a lot of beheading), which the second part acknowledges. 'There are no endings,' Cromwell says. 'They are all beginnings. This is one.' And gripping enough that I suspect nearly all of us will be back in these seats in a few years time, eager to see - 500-year-old spoiler alert - the bloody conclusion.
