To start with, I occasionally write for What Would The Founders Think? and the reviewer is a friend. But ... it's a good review, so I'll shamelessly promote it on my site.
Martin writes, "The Shut Mouth Society is a potboiler of the first order. James Best fans will be surprised as the author steps a bit outside of his regular genre, the classic American Western, and gives hero Steve Dancy a break ... The Shut Mouth Society is written in a “never mind maneuvers, go straight at ‘em,” style. He never resorts to Deus ex machina to resolve a pretty turbulent plot, but keeps the reader guessing until practically the end, with plausible, if surprising twists."
