Reformed miser Ebenezer Scrooge has been voted the most popular Charles Dickens character, according to a poll held to mark the 200th anniversary of the author's birth.
Seven out of the top 10 characters chosen by Penguin readers were villains or some of Dickens' darker creations, with vengeful Miss Havisham from Great Expectations coming second.
The jackal-like Sydney Carton, the pick-pocketing Artful Dodger and his criminal ring-leader Fagin completed the top five.
Claire Tomalin, acclaimed Dickens biographer, said: "People love villains and Dickens' villains are so well-drawn. He filled them with such energy - they are more striking than his good characters.
"The thing about Scrooge is that he's a double-whammy - he's allowed to repent and become a good character but he is more interesting when he is being bad."
She added: "Scrooge's popularity is surprising, since his modern equivalent might be a banker.
"But Dickens excelled in creating villains, and always gave them more energy and brio than his good characters, so that we never forget them.
"Scrooge is a monster, a wicked employer and a heartless miser, but he is allowed to repent and see the error of his ways.
"So perhaps it's the contrast between his outrageous meanness and coldness and his cheery generosity and lavishness at the end that readers respond to."
The only three good guys chosen were David Copperfield's Betsey Trotwood, and Joe Gargery and Pip from Great Expectations.
A Penguin spokeswoman said: "With most of the top 10 characters appearing in either Great Expectations or Oliver Twist, it would suggest that these two novels have struck the greatest chord with the public, although Oliver himself came in at number 11."
Best-selling authors were also asked to choose their favourite.
Freya North opted for Uriah Heep, describing him as a "loathsome character who seeps from the pages like a noxious gas".
Daisy Goodwin picked "the anti-heroine of Bleak House", Lady Dedlock, while Adele Parks chose the "morally ambiguous" Nancy from Oliver Twist.
Tim Lott and Josephine Cox cited Pip and Oliver respectively.
Simon Winder, Penguin publishing director and Dickens expert, said: "Dickens was a master at creating character, particularly those with a dark side.
"How fitting then to mark his 200th birthday with a celebration of his finest creations."
