What if everything you've ever heard about Jack the Ripper is wrong? A young woman is brutally murdered in Washington D.C., and the killer leaves behind a calling card connected to some of the most infamous murders in history. Jack the Ripper Rookie homicide investigator Erin Prince instinctively knows the moment she sees the mutilated body that it's only a matter of time before someone else dies. She and her partner, Todd Beckett , are on the trail of a madman, and a third body sends them in the direction they feared most: a serial killer is walking the streets of D.C. The clock is ticking. Erin must push past her mounting self-doubt in order to unravel a web of secrets filled with drugs, pornography, and a decades-old family skeleton before the next victim is sacrificed. The only way to stop a killer is to beat them at their own game.
