Lawyer Melissa Gale has dedicated her life to tracking down Nazis, in memory of her Holocaust survivor grandmother. Happily married to a Washington Post journalist, she is on the trail of a particularly elusive Nazi, Adalwolf, who always seems to be one step ahead of her, and who has apparently manufactured a lethal virus with which he is infecting random civilians. On a personal level, she is having fertility treatment for a much wanted baby. A debacle in which an American war veteran is killed in place of Adalwolf coincides with Melissa's pregnancy and she decides to work unofficially on the case for its duration. But Adalwolf has other ideas: Melissa's baby is a vital part of his genocidal plan, and the race is on. Can Melissa get to him before he gets to her?
