For Jack Whalen, it all starts with a visit from a childhood friend, now a lawyer, who asks for his help on an odd case. The family members of a scientist have been brutally murdered, and the scientist—who may have had something to hide—is nowhere to be found. But Jack has more pressing matters on his mind. His wife has told him that she's on a routine business trip to Seattle, yet she hasn't checked into her hotel. Calls to her cell phone go unanswered, and when Jack travels to Seattle to investigate, she's vanished.
