London, 1803. Verity Travers is a 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. However, when she and her friend become victims of an armed robbery, Verity seeks to bring the thief to justice. There's just one complication: the Bow Street Runner Nathaniel Denning, who always seems to cross her path. Focusing on the task at hand becomes difficult as she constantly bumps into Nathaniel. The two investigators must figure out how to navigate increasing peril and an irresistible passion that sets their hearts ablaze.
