Charles Dickens describes in Night Walks his time as an insomniac, when he decided to cure himself by walking through London in the small hours, and discovered homelessness, drunkenness and vice on the streets. This collection of essays shows Dickens as one of the greatest visionaries of the city in all its variety and cruelty.

GREAT IDEAS.

Throughout history, some books have changed the world. They have transformed the way we see ourselves

and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives

and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
