Miss Genevieve Wilde--a magistrate's daughter and independent heiress--is determined to meet life's challenges all on her own, just as her late-father had taught her. So when her father's pocket watch is stolen, she will do anything to get it back, especially when the local authorities prove incompetent.

Upon reading an advertisement in the paper, she takes a chance and contacts a thief-taker to find the watch. It's a choice Ginny regrets when former Bow Street officer Jack Travers arrives on her doorstep. He is frustratingly flirtatious, irritatingly handsome, and entirely unpredictable, and Ginny wonders if she'll be able to resist such a man.

But after Ginny discovers that the missing watch is just a small part of a larger, more frightening plot against her, she needs Jack's help more than ever. To protect her home and her reputation, the two enter into a risky charade--pretending Jack is her cousin so he can begin his investigation, starting with the household staff. As they work together to unravel the mystery, Ginny finds herself falling fast for her charismatic thief-taker, leaving her heart in just as much danger as her life.
