Book published for capital's famously unfriendly travellers

Books of the year 2013: Sport

The memoir is the staple diet in sports publishing, and this has been a particularly full-on year for them. The more honest the better, of course, and there's none more so than Mike Tyson's Undisputed Truth: My Autobiography (Harpersport, £20). It's full of staggering stories: fighting high on coke and dope – which didn't stop him winning a fight in 38 seconds; wearing what he calls a "whizzer", or fake penis filled with clean urine, to foil the drug-testers; badly beating up fans who asked for autographs… Tyson is in full-on confessional mode and I can't recall a more self-excoriating autobiography, but it makes for grimly compelling reading.
