". . . Abraham Lincoln was known for his smarts and his kee-slapping humor. In 1842, that got him into a heap of trouble. When he clashed with James Shields, a political rival, Lincoln came up with a rascally plan. It was silly. It was clever. And it was a great big mistake! Shields challenged Lincoln to a duel! Lincoln would need his wit and a healthy dose of humility to save his career--and maybe even his life."--Provided by publisher.
