What is the Charles Dickens novel - barnaby?

You're likely thinking of "Barnaby Rudge: A Tale of the Riots of 'Eighty", a novel by Charles Dickens published in 1841.

The story follows the adventures of Barnaby Rudge, a young man with learning difficulties, and his loyal raven, Grip, against the backdrop of the Gordon Riots of 1780 in London.

It's not as famous as some of Dickens' other works like "A Tale of Two Cities" or "Oliver Twist," but it's still a compelling read with strong characters, social commentary, and a good dose of suspense.
