author gallery function, which arrays portraits of the people who wrote the books in your library, in alphabetical order. This can throw up a few rather startling lookalikes – as distinct from lookunalikes – adjacent to each other. Who’da thunk that Anthony Beevor and Frédéric Beigbeder would be so similar; or Malcolm Bradbury and André Breton; Ian McEwan and Roger McGough? The only problem is that now I don’t want to split up these unlikely twins, which means I’ll probably never sample from the wells of Aphra Behn, Wallace Breem or Leslie McFarlane. Sorry.
