X-Factor: They Keep Killing Madrox

In this 2012 one-shot from Marvel, writer Peter David and artist Emanuela Lupacchino deliver a standalone X-Factor mystery that puts Jamie Madrox—the Multiple Man—through a dizzying, dangerous puzzle. When someone keeps murdering Madrox's duplicates, the detective team must untangle a crime that blurs the line between victim and perpetrator. It's a tight, clever character piece that showcases David's long-running affection for the X-Factor cast and Lupacchino's clean, expressive storytelling.
