Sergeant Amy Callan and Lieutenant Caroline Cook have a lot in common. They’re both high-flying army career women, they’re both victims of sexual harassment by their superiors, they’re both forced to resign from the service.

And now they’re both dead.

They’re discovered in their own homes, naked, in baths filled with army-issue camouflage paint, their bodies completely unmarked. Expert FBI psychological profilers start the hunt for a serial murderer, a smart guy with a score to settle, a loner, an army man, a ruthless vigilante known to them both.

Jack Reacher, former US military cop, is a smart guy, a loner and a drifter, as tough as they come. He knew both victims. For Agent-in-Charge Nelson Blake and his team he’s the perfect match. They’re sure only Reacher has the answers to their burning questions: how did these women die? Any why?
