A robbery, the murder of a pregnant schoolteacher, followed by the disappearance of three witnesses - all take place at a Lake Tahoe motel and lead to a wrongful death suit. Time is running out on the case and there has been no significant progress; the previous attorney wants out. Nina Reilly takes over the case of the bereaved spouse, at the personal request of the victim's niece.
Her first action is to locate the witnesses - three brilliant math students - and she tracks two of them to Boston. When she finds the third in an island near Seattle, she has a plan.
But then more people start turning up dead, and all indications are that the man who robbed the students at the motel is responsible. As more facts surface, it becomes clear that money alone was not the motive - one of the students has a secret notebook in which he has recorded his work on a significant mathematical proof, and coincidentally, a large corporation in Seattle wants the notebook.
But the more Nina Reilly investigates, the more twisted become the facts. Soon, nothing is as it seems. And in a final confrontation between the alleged killer and her client, a whole new array of facts unfold. Only one man will still be standing in the end, and what she learns after it is over will blow Nina Reilly's mind.
