An utterly unique, Victorian-era mystery with a clever play on the famous Dr. Jekyll and Mr. Hyde tale, where the monster becomes the hero, and lines are crossed along the way.

Unbeknownst even to himself, the kind, gentle, quietly brilliant Dr. Jekyll has created an alter ego—his polar opposite, the dark and dangerous, Mr. Hyde. A little bit Dexter, Hyde hunts down criminals to make them pay for their sins. But his "good deeds" go too far and, now, wanted for murder, he must lay low . . . until his love interest comes into Jack the Ripper's sights.

Francine Murphy, a social reformer years ahead of her time, walks the mean streets of Whitechapel London, rescuing the gin-soaked prostitutes that "Jack" preys upon. But as she gets closer and closer to the truth, will she become the Ripper's next target? Hyde and his exceptional investigation skills—and his wicked hand—may be all that saves her.

A rich-new voice in historical mysteries, John A. Hoda, is an ex-police officer and private investigator, as well as a three-time winner of the publisher's award from the Legal Investigator.
