Saucy Jack

There's a killer loose on the streets of Whitechapel and it seems no one is safe.
It is 1888 and a woman is found murdered. Throat slit and badly mutilated, the police are at a dead end. As time goes on more are found dead. All in the same manner. With time Ticking, twins Edward and Elizabeth Warren must race to solve the mystery before anyone else gets hurt-and before Elizabeth herself is a victim.
