Lizzie Ferguson is not a typical 1912 woman.

Owner of the E.M. Ferguson Detective Agency, she prefers to live life outside of society's norm – both in and out of the bedroom – which leads to complications when she finds herself attracted to her beautiful assistant, Julia Straton, and an arrogant, yet devastatingly handsome journalist named Walton Crew. But who has time for romance when there are murders to solve?

Her newest case is eerily similar to one from the past. Male brothel workers are being butchered, so she calls on old friends and Pinkerton detectives, Michael O'Leary and Stiles Long, to help track down the killer. Working together, the three friends race against the clock to prevent more blood from being shed, but when all is said and done, will the citizens of New York City accept Lizzie for who she is?
