The visitor

"The Visitor offers an efficient mix of hard-boiled style with lots of lip and a revival of the classic locked-room mystery. . .Tight plotting, pace and high mileage." (Guardian ) Sergeant Amy Callan and Lieutenant Caroline Cooke have a lot in common. Both were army high-flyers. Both were aquainted with Jack Reacher. Both were forced to resign from the service. Now they're both dead. Found in their own homes, naked, in a bath full of paint. 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. Although the Jack Reacher novels can be read in any order, The Visitor is 4th in the series.
