Book excerpt: The recent discovery that as a young man Charles Dickens lived only a few doors from a major London workhouse made headlines worldwide, and the campaign to save the workhouse from demolition caught the public imagination. Internationally, the media immediately grasped the idea that Oliver Twist's workhouse had been found, and made public the news that both the workhouse and Dickens's old home were still standing, near London's Telecom Tower. This book, by the historian who did the sleuthing behind these exciting new findings, presents the story for the first time, and shows that the two periods Dickens lived in that part of London - before and after his father's imprisonment in a debtors' prison - were profoundly important to his subsequent writing career.
