Sergeant Amy Callan and Lieutenant Caroline Cook have a lot in common. Both were army high-flyers. Both were acquainted with Jack Reacher. Both were forced to resign from the service. Now they're both dead. Both were found in their own home, naked, in a bath full of paint. Both apparent victims of an army man. A loner, a smart guy with a score to settle, a ruthless vigilante. A man just like Jack Reacher.
