Paul Thomas, for example, writes crime novels as well as sports biographies; Quinn Berentson is a writer, documentary film-maker and photographer who has written the Quinn-tessential work on the New Zealand moa; Sarah O'Neil writes about gardening; Tim Wilson is a novelist and short story writer - and you would have seen him on the telly. That's just four of the nine.
