No. 21 was another John Sandford hand-me-down from Pa.
Mad River was a totally different story with different characters. I kinda assumed it was a series. Nope.
It was about a Minnesota Bureau of Criminal Apprehension detective chasing down a couple on a crime spree. It really held my attention! Instead of trying to figure out the mystery, we were just cheering along the police to catch the bad guys before they killed any more.
A good read!
