When London discovered that Jack the Ripper was back, it sent Scotland Yard’s Murder Squad into chaos. But now it is even worse. There are two of them. When the Harvest Man begins killing, carving people’s faces off their skulls, the men of the Yard know they need Inspector Walter Day to find him before more families are murdered. Meanwhile, Saucy Jack is playing his own games-and when the two killers come together, the men of the Yard may never be the same.
