Madeline Hunter, The Romantic: the taciturn, intelligent hero has a lifelong crush on the sweet, loyal heroine, who unfortunately married someone else years ago. Her husband, alas, turned out to be Evil. Now she's separated from her husband, but he wants her back to produce an heir. The hero, her solicitor, both wants to keep her safe and get her free so he can declare himself. This one would make a fun movie, I think. All sorts of dramatic confrontations and escapes and trials and such. I liked this one the best of this series.
