Collects X-Factor (2005) #229-232. X-Factor has suffered its greatest casualty yet: Madrox, the man of many multiples who’s led the team since its inception, is gone. It wasn’t supposed to be this way, but only Layla Miller knows why — and the secret she’s keeping goes to the heart of her powers and purpose with X-Factor. With their fearless leader dead, and the schism between Wolverine and Cyclops ripping the mutant world apart, X-Factor’s future is uncertain. That’s why Wolverine has paid the team a visit, offering a shocking new option for the world’s only mutant detective agency. It’s two for the price of one as Havok and Polaris return from exile to take charge of X-Factor Investigations! But is Madrox really dead? Even Jamie isn’t sure!
