To Hunt an Heiress by Martha Keyes

He’s after her heart—and her money. He’ll have to fight her for his dignity first.

Sebastian Drake is in dire need of a fortune. With limited time and a dearth of wealthy relatives to will him such a thing, he is left with only one option: marry money. Happily, London is full of eligible heiresses, but it is the newest arrival in Town who catches his eye.
Selina Lawrence is only just rid of one husband—the last thing she wants is to acquire another. When she finds herself the target of the charming Mr. Drake, a suspected fortune hunter, what is she to do but teach the man a valuable lesson?
However, both Sebastian’s attempts to woo Selina and her efforts to humble him backfire in unexpected ways, leaving them entangled in a battle of wits and hearts.
