Danger and passion collide when a plucky young woman becomes embroiled in a Bow Street investigation alongside a handsome officer.

London, 1803

As the daughter of a renowned actress, Verity Travers is a privileged lady of high society --and the last woman one would suspect of working as a private investigator. But after one case nearly costs her everything, she makes the hard decision to hang up her hat and live the uninspiring life of a gentlewoman. However, when she and her dearest friend become victims of a harrowing armed robbery, Verity finds herself swept back into the clandestine world of mystery and crime as she seeks to bring the thief to justice. There's just one complication: the persistent and dashingly handsome Bow Street Runner Nathaniel Denning, who always seems to cross her path.

Verity is confident she could accomplish her work quickly if only Nathaniel would stay out of her way. While she appreciates his keen mind and quick wit on a case, his interference is muddling her progress--and her heart. Focusing on the task at hand becomes more and more difficult as she constantly bumps into Nathaniel, who is determined to keep her out of danger.

When the two rival investigators learn they are both pursuing the same cunning criminal, they must figure out how to navigate the delicate dance of cooperation amid a backdrop of increasing peril and an irresistible passion that sets their hearts ablaze.
