Sherlock Holmes has become more ruthless, more dangerous, and more obsessed than ever before. The world’s greatest detective teams up with hell’s most ruthless hunter — driven by vengeance, Holmes joins forces with Narkrow to hunt down the world’s most infamous serial killer.

The plan is ruthless. The bait is personal. Holmes puts his own love in the line of fire like a lamb to a wolf, because sometimes, the only way to catch a monster, is to become one.

But when Narkrow finally confronts Jack the Ripper, the streets of Whitechapel become a battlefield of blood, vengeance, and punishment. And when the nightmare ends, the world will finally know the name behind the mask, the motives behind the murders, and the truth behind the vanishing of Jack the Ripper.
