It is a year after August Street, a senior fellow at the H P Carlisle foundation (a research institute), has published a book entitled "Raven". Though Street used Top Secret British documents that are now declassified to describe the book's events, he and his publisher agreed to release the book as fiction. Street believes the story is about the darkest days of World War II. When Britain prepared for the invasion code-named Operation Sealion, Britain ambushed Hitler's private train, killed Hitler, and had actor Archie Smthyes impersonate the Nazi dictator long enough to issue a single order: Stand down from Operation Sealion. And when it came time for Smthyes to step down and escape the Nazis, he refused. Consequently, two fatal decisions were made in Churchill's war room. The first resulted in the murder of six million Jews, and the second cost the lives of 20 million Russians. The HP Carlisle foundation confronts Street to sign a document asserting that Raven is nothing more than the product of his imagination. When Street refuses, he is released from the institute. This he can accept, but when he realises that he is being stripped of his identity -- and his physical presence in America -- he is forced to act!
