Jack Reacher got dumped. No surprise there. Not a lot of women could be a drifter like him.
So, he kind of drifted again. And while he is on the road, he came across a West Point ring, woman's size.
So instead of reflecting on why he got dumped and how he could improve his situation, he is now focus on who this ring belonged to and why this is on sale in a pawn shop.
That led him to a thief, then another.
The start is good. Reacher is a bit more mature, but not quite.
