Spoiler:

In these seven mysteries Sheriff Jeff McQuede finds himself in the middle of a deal made on a handshake—where the result is murder. Set in the high county of modern-day Wyoming, the deal makers are speculators at an old-time mountain man rendezvous, traders vying over rare Native American pottery, or two family patriarchs pretending to bridge a lifetime of feuding. Throughout McQuede battles his arch-enemy Ruger, who he suspects runs a host of illegal activities, but generally manages to evade McQuede’s traps.

In each of these stories McQuede, putting his own life on the line, relentlessly seeks out the dangerous men who have broken trust.
