Kate Summers's career on the police force came to an implosive end when the mayor's wife exposed her secret life as the Mistress of Pain. Kate lost not only her detective's badge but something much more valuable: she lost her confidence as a Mistress of men. She now scrapes by as a private investigator, feeding off the misery of others. When the mayor and his wife ask her to investigate the murder of their daughter, Kate faces a difficult decision. To follow the leads, she must reenter the world that destroyed her career and go undercover as a submissive to a noted Dom. Only Kate swore she'd never endure the submissive role again. Yet Jake Davenport is the one dominant fearless enough to not only challenge her rules, but to break them. While accepting her new role and the erotic thrill it brings her is difficult enough, Jake's complicated past raises many questions. As her investigation progresses, Jake might just be her number one suspect.
