Before the age of the gas lamp, the city at night was a different place, home to the lost, the vagrant and the noctiambulators. In this brilliant work of literary investigation, Matthew Beautmont shines a light on the dark perambulations of poets, novelists and thinkers from Shakespeare, the ecstatic strolls of William Blake, the feverish urges of opium addict De Quincey as well as the master night walker, Charles Dickens.
