For fans of HBO’s The Gilded Age, explore the dark side of the alluring world of America’s 19th century elite in this gripping series of riveting mysteries… In 1880s Chicago, Shakespearean actress turned Pinkerton detective Lilly Long must play the part of a soiled dove to find a missing friend . . . As one of a handful of female operatives employed by legendary crime fighter Allan Pinkerton, Lilly draws on her theatrical training to go undercover in situations inaccessible to male detectives—much to the discomfort of her partner, Cade McShane. Their latest case takes them to the rough and rowdy bordellos that line Hell's Half Acre in Fort Worth, Texas—truly the Wild West. By virtue of her gender, only Lilly can infiltrate the disreputable dens of iniquity that trade in flesh and cater to vices that would make even a Pinkerton blush. This time the case is deeply personal. Lilly's friend, Nora Nash, who traveled to Fort Worth as a mail-order bride, has instead been forced into prostitution. After a desperate call for help, Nora has gone missing. To find her, Lilly must revamp herself as a vamp and expose a seamy underworld of unspeakable secrets where anything goes. But she and Cade soon discover firsthand that lives are cheap in Hell's Half Acre—including their own . . .
