Pinkerton Detective Tom Comfort travels to Highgrade, a frontier boomtown, in the Sierra Nevada mountain range of California, in 1878. Comfort's mission is to take charge of a shipment of gold bullion and protect the shipment from a gang of cutthroat bandits led by Mortimer Helshaw. Comfort's client is the beautiful and petite businesswoman Marguerite May. A whirlwind romance develops amidst gun battles with the murderous Helshaw. Informants give away Comfort's plans to the outlaws, and the story culminates in an exciting train robbery. This fast-paced tale is packed with action and adventure. You won't want to put it down. Inspiration for the story came from a visit to the real-life ghost town of Bodie.
