The Bodine ranch and resort in western Montana is a family business, an idyllic spot for vacationers. A little over thirty thousand acres and home to four generations, it’s kept running by Bodine Longbow with the help of a large staff, including new hire Callen Skinner. There was another member of the family once: Bodine’s aunt, Alice, who ran off before Bodine was born. She never returned, and the Longbows don’t talk about her much. The younger ones, who never met her, quietly presume she’s dead. But she isn’t. She is not far away, part of a new family, one she never chose—and her mind has been shattered...
When a bartender leaves the resort late one night, and Bo and Cal discover her battered body in the snow, it’s the first sign that danger lurks in the mountains that surround them. The police suspect Cal, but Bo finds herself trusting him—and turning to him as another woman is murdered and the Longbows are stunned by Alice’s sudden reappearance. The twisted story she has to tell about the past—and the threat that follows in her wake—will test the bonds of this strong family, and thrust Bodine into a darkness she could never have imagined.
Their investigation, however, yields more questions than answers. It quickly becomes clear that the victim, John Pearce, was more than the naval historian and antiquities dealer he appeared to be. What Drummond doesn’t know is that buying and selling rare books was Pearce’s cover, and that he had devoted his life to discovering the whereabouts of a missing World War I U-boat concealing a stash of gold bullion, and an unexpected surprise that only raises more questions. When Drummond and Caine find both of Pearce’s adult children have disappeared, the case assumes a new sense of urgency. The FBI agents know their best lead lies in the victim’s cryptic final words—“The key is in the lock.” But what key? What lock?
The search for Adam and Sophia Pearce takes them on an international manhunt, which threatens to run them afoul of an eccentric billionaire industrialist with his own plans not only for the lost gold, but the creation of a weapon unlike anything the world has ever seen.
