Among the biggest surprises of this year’s Man Booker Prize longlist was the inclusion, for the first time in the prize’s 50-year history, of a “graphic novel”. Nick Drnaso’s Sabrina — a chillingly claustrophobic account of the aftermath of a murder in post-truth America — is undoubtedly a brilliant example of its form. But does a comic belong in contention for a fiction prize? I didn’t think so (and wrote as much in the FT). In this week’s Books Podcast the Man Booker Prize’s Literary Director, Gaby Wood, argues otherwise — and raises in the process the possibility that, one day, the Man Booker prize could be won by a book that doesn’t contain any words at all.
