The Eyre Affair by Jasper Fforde

Hitchhikers Guide meets the Classics. This is this author’s first novel and it’s great – very clever, well-written, lots of word play, and thoroughly entertaining. Set in an altered version of London in 1985, literature is so important, there’s a division of the “police” that handles “literary crimes” (like forging Byronic verse), time-travel is common, and (some) people can move between the “real” world and the worlds in literature. The heroine is a “Literary Detective” chasing a bad guy who’s kidnapping characters out of literature. I’ve also read his second book Lost in a Good Book, and his third (can’t remember the title) but they weren’t as good.
