London, 1888

Whitechapel is full of the noise of August Bank Holiday celebrations. Everyone is in high spirits until a woman – Martha Turner – is discovered brutally murdered.

Her friend, Esther, a lowly seamstress turned female sleuth, is determined to find the killer.

A young police officer, Jack Enright, takes the lead on the case, and he and Esther soon embark on a professional – and personal – relationship.

When another murder is committed and whispers of a slasher calling himself Jack the Ripper start flowing through the London streets, the search becomes even more desperate.

The police are on the wrong track and the young couple take matters into their own hands, and soon find themselves navigating through London’s dark underbelly.

Can they find the murderer before he kills again? Will anyone listen to their suspicions?

Or will this dark presence continue to haunt Whitechapel…?
