Jack the Ripper faded into history over a century ago, his identity lost to the ages. Until a work crew restoring a Mayfair home make a shocking find. A secret basement room walled up since Victorian times. The Whitechapel murderer's lair. And inside, a corpse that has waited in silent darkness for over a hundred years. But it won't stay that way... Within hours of the room's discovery, the body goes missing, and the murders begin anew. With a violent killer on the loose and the body count rising, John Decker, still new to CUSP, is sent to England, along with seasoned operative Colum O'Shea. Their mission: stop a ruthless monster from obtaining the one thing that will allow him to escape forever. As the city huddles in fear and the terror mounts, Decker finds himself in a race against time to catch a hellish fiend smarter than any he has ever faced. Because if he doesn't, the next death might hit a little too close to home.
