When high school chemistry teacher Mike Garretson learns one of his ancestral relatives was the victim of identity theft, long before it became the preferred crime of today's white collar thieves, he suddenly finds himself having to prove it before he ends up as dead as his murdered grandmother. Mike's only hope of winning the family inheritance is to hire historian Dr. Jennie Foster. But as she begins to uncover nearly century-old family secrets, Mike fears the feisty and brainy Jennie may discover more than he wants her to know. Jennie's happy to climb around in her mysterious and aloof co-worker's family tree. At least until she discovers Mike has a few secrets too. As the ancestral body count rises and a modern killer discovers what they're looking for, will Jennie lay her life-and her heart-on the line for a man who refuses to let her into his?
