The Visitor, Lee Child

Featuring Jack Reacher, hero of the blockbuster movie starring Tom Cruise.

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.
