One of the best spy novels set in World War II that I have read. I am considered one of the top historians on World War II and I am amazed that this novel by John Altman finally had the setting of the Manhattan Project as its setting. In 1943 Stalin had 3 spies in New Mexico giving him weekly reports, one of these spies was a double agent who also kept Hitler informed. John Altman has created a great character in this Female Nazi Spy. She can kill you just like she can bake cookies!! The only other novel I have read that is this good is, "The Vahalla Exchange," by Jack Higgins!!
