New York City's untouchable head of detectives, Thomas Byrnes, swears he put the right man behind bars, but as Mary digs deeper, she finds corruption at the heart of New York's justice system, involving not only the police, but also the most powerful of stock titans. Disturbing evidence of other murders begins to surface, each one mimicking Jack the Ripper's style, each one covered up by Thomas Byrnes.
As Mary pieces together the extent of the damage, she crosses paths with Harper Lloyd, an investigative reporter. Their relationship grows into a partnership, and perhaps more, and together they must catch a killer who's still out there, and reverse the ruthless workings of New York's elite. It'll be Mary's most dangerous, most personal case yet.
