Edinburgh is UNESCO's first world city of literature. Everyone from Burns to Stevenson and Conan Doyle to Ian Rankin lived or wrote here, and a walk with a drink is the best way to find out about them. The Edinburgh Book Lovers' Tour takes you through the Old Town at night, weaving from pub to pub telling stories and reciting extracts. If you're a particular fan of just one grumpy detective, Rebus Tours will take you to the scenes of some of Britain's best-selling crime novels.
