"The Spider. The most violent and ruthless of all crime fighters, a cloaked, fanged, borderline crazy denizen of the dark force-feeding hard justice with a pair of '45's! Join Doc Savage novelist Will Murray as a new reign of terror has begun in Manhattan, something not seen in generations. All over town, people in all walks of life are found murdered-scalped! Nita is kidnapped. Then what appears to be her blonde scalp arrives at police HQ in a box. But the box contains a clue and so a maddened Spider follows that clue to Red Tomahawk, to rescue Nita and end his reign of blood."
