One of the things that Terry Pratchett has always done well is a large cast of characters. His stories generally have the key figures - Granny Weatherwax, Tiffany, Vimes - and a few secondary ones who are there throughout the narrative. But the Discworld is populated by a vast array of folks, and they are pretty much all interested in getting a share of page-time. In today’s essay, Tansy Rayner Roberts looks at Witches Abroad, and in particular examines the male supporting characters who help make the story work - even though, in some cases, they’re not actually on the page, and in most cases they don’t really get to talk. And two of them aren’t really men.
