According to The Kenyon Review blog:
... the lost Alexandre Dumas novel The Last Cavalier will be released by Pegasus in October, reports Publishers Weekly. The book was found in the National Library in Paris two years ago by Dumas expert Claude Schopp, who also added a conclusion to the unfinished novel. The book, published in France in 2005 as Le Chevalier de Sainte-Hermine, “gives a full account of the Battle of Trafalgar, which explains that the hero of the book was responsible for the death of Lord Nelson.” According to BBC News at the time, the novel “has been described as ‘indescribably brilliant’ by scholars.”
I wonder which scholars called it ‘indescribably brilliant’? I somehow can't imagine very many having the balls to call it ‘indescribably crap’!
