Deep Down: A Jack Reacher Story is a very short story. Jack Reacher must uncover a military spy. There four female Colonels working on procurement of a new sniper rifle for the US Army. Once he solves the mystery, he has to fight his way out of a trap. The story takes place before all the other Child books. Reacher is still a Captain in the Military Police. This short story isn’t long enough for Child to develop a decent plot. It’s rather flat.
