A member of X-Factor dies! It started with their new acquaintance, Sally, found brutally slain in her kitchen. And more recently, two rival gangs, lifeless bodies sprawled across a basketball court, a noose around each of their necks. Hot on the trail of a serial killer who's lynching his victims, the mutant detectives of X-Factor Investigations are eager to cut his killing spree short. But here's hoping they find him before he finds them!
