there is an ACE here: Silken Threads

Graeham Fox comes to London to rescue his overlord’s daughter from her abusive husband, in return for which he is promised her sister’s hand in marriage and a vast estate—quite a prize for a landless soldier who’s never had a home of his own. Attacked and disabled by a broken leg, he rents a room in the humble home of Joanna Chapman, a silk merchant’s widow. Joanna, having learned not to trust handsome, charming devils like Graeham, lets him think her husband is still alive in order to keep him at a distance. Mindful of his mission—and the promised reward—Graeham tries to resist his feelings for Joanna, but the white-hot desire simmering between them cannot be denied.
