Pickpocket Countess (Harlequin Historical Series)

It's Brandon Wycroft's duty as the Earl of Stockport to catch the "Cat," a notorious thief who is stealing from rich local homes to feed the poor. Discovering that the Cat is a woman, he changes his plan of action--to a game of seduction! Mysterious and tempting, she teases him. And, as the net closes around the Cat, Brandon realizes he wants to protect her as well as bed her. But the only way to catch her is to spring the parson's mousetrap--and make her his countess!
