The Knight of Sainte-Hermine

The Knight of Sainte-Hermine (published in France in 2005 under the title Le Chevalier de Sainte-Hermine) is an unfinished historical novel by Alexandre Dumas. Believed to be Dumas' last major work, the novel was lost until the late twentieth century. The Dumas scholar Claude Schopp found an almost-complete copy in the form of a newspaper serial. While a number of Dumas' previously forgotten works have been found, at 900 pages, this novel is the largest and most complete.

The novel is a swashbuckling tale set during the rise of the Napoleonic Empire. A key scene features the Battle of Trafalgar, and the death of the British admiral Horatio Nelson. Translated into English, it was published in 2007 as The Last Cavalier, and has since been translated into other languages.
