1815 for a mystery novel of fanciful aspects. For Richard Darvent is to hang for having killed Lord Orford in a duel, in a room which has disappeared, and, to earn fifty pounds for the actress he loves, he marries imperious Caroline Ross to insure the safety of her fortune. But he is reprieved when the defeat of Napoleon clears the way to his inheritance, and, as a peer, he repays Caroline for his humiliation and starts the long search for the truth of his innocence. Most superior.
