Will medical research unravel the secret to immortality? Or will it be stolen by a master of manipulation, deceit, and murder? Professor Brad Parker is enjoying his sabbatical in one of Harvard's leading genomic engineering labs, focused on altering the human genome to meet challenges like treating cancer and increasing longevity. Then he's interrupted by a surprise request from the FBI. Can he help them track down a Chinese spy who's stealing the lab's secrets? Becoming engaged in a case of criminal conspiracy is the last thing Brad wants to do -- but at the urging of Karen Richmond, his partner and now an FBI agent herself, he agrees. The ensuing hunt takes Brad and Karen down a trail of treachery and death that leads from Boston to the coast of southern Maine, where a killer lies in wait.
