Elizabeth Thornton's "Scarlet Angel"
Got about 2/3 of the way through this, but finally set it aside. The main characters didn't really engage me, especially the hero, who was actually rather despicable in what he did to the heroine. Yes, his stepmother and sister had been killed partly as a result of the heroine's actions as a seven-year-old child, but two wrongs have never made a right. The description of the early 19'th century political manoeuvering by Charles Fox, William Pitt, the Prince Regent, Fouche, Talleyrand and the others didn't really have much of a connection to the story and wasn't very interesting anyway.
