The Duke of Danger

When Lady Emmaline Townsend's husband is killed in a duel she vows revenge on his killer, Lionel Maitland, Marquess of Axbridge. However, less than a year later and faced with an arranged marriage to a lecherous man old enough to be her father Emmaline summons him back to London with a proposition, marry her as penance for the murder of her husband. Lionel has killed two men in duels, something he never wanted to do, and is tortured by guilt. Although a loveless marriage in name only would mean the title would pass to a distant cousin and deny Lionel the joys of love and children he feels he must marry Emmaline to atone for his actions. However, very soon he finds himself falling in love with his wife. Lionel can never tell his wife why he challenged her first husband to a duel, or that her husband shot before the count of twenty. I love a good marriage of convenience historical romance, and how much more delicious when it's with the man who murdered your husband, even if your marriage was deteriorating and your husband turned out to be an inveterate gambler. Just loved it.
