Missouri Mastermind — Jon Sharpe

When the Pinkertons ask Skye Fargo to infiltrate a small gang of brutal killers, he has no idea what he's in for. Because the gang is only a tiny piece of a much bigger “syndicate” that has its filthy hands in a lot of pies -- and it's up to the Trailsman to climb up the lowlife ladder and take down the head honcho...if someone doesn't take him down first.
