A fortune is at stake and Noah MacLean, once a ghost among Mosby's Raiders, finds himself chasing a ghost, Emilia Ashley, who has left Philadelphia for San Francisco. A man named Dillon Sinclaire wants her found, and perhaps, buried.

An accident has left Emily's mother, the madam of a renowned Philadelphia brothel, and the wealthy Mr. Sinclaire dead, catapulting Emilia to an inheritance that hinges on distant gold. But Sinclaire's son has no intention of letting Emilia claim what he believes is rightfully his. He's hires Pinkerton detective, Noah MacLean to track her down and prevent her from getting her hands on his inheritance.

Noah, a man whose grit was forged in conflict, feels the dark currents swirling around Sinclaire. As the West beckons and secrets unravel, will Noah's duty to his client allow him to betray Emily?
