I've read enough of Steve Richer's work now that I'm comparing him to himself. This is a very good story involving the plates for printing Iranian currency. Mercury Cale, a special agent of some sort, is tasked with their recovery.
The story is well written, and features non-stop action. It reads like you're watching a movie. It's a fun experience. Good characters who could use a little more depth, but characters I'd like to get to know further.
It's not Richer's best, but it's still very good.
