Downriver (The Amos Walker Series #9)

In this outing, Walker goes "Downriver," which is a Detroiter's term for any part of Michigan that does not include the city. Actually, he goes to the Upper Peninsula to give a released con a ride back to Detroit. When he and the con get run off the road and the con hires him to help find 200,000 dollars from a heist for which he was convicted but which he did not commit, Walker has his hands full.
