London, 1888...Two serial killers, Leather Apron (Jack the Ripper) and the Torso Killer are mutilating women in the slums of Whitechapel. But even in the bedchambers of the peerage, a killer is claiming lives. A determined Lady Kiera Everett wishes to hire the Zane Brothers Detective Agency to prove that her sickly father, and two other ailing members of the peerage, were murdered by their attending nurse, named in each man's Will, but only if Kiera can be involved in the investigation, much to Zachery Zane's chagrin. And soon the murders of Whitechapel intersect with the investigation conducted by the Zane brothers.
