FLASHPOINT IN

The following is the fictional story of how the United States and the Britain foiled an attempt by Nazi Germany, mid-World War II, to assassinate the President of the United, Franklin D. Roosevelt, the Prime Minister of Great Britain, Winston Churchill, and the Premier of the Soviet Union, Marshall Joseph Stalin. While much of the information is subject to conjecture, a majority of the information is based on facture data!
The German intelligence service (the Abhwer) had somehow obtained or broken the U.S. Navy's latest code and were able to obtain the dates, locations, and names of personnel attending the Tehran Conference, in Tehran, Iran. From this information, a plan was formulated to assassinate the three heads of the warring powers against Germany, thus causing a different conclusion to the war, than planned for those of the three powers.
The following story is one possible scenario of how events might have happened, and how it might have been dealt with!
I leave it to the reader, to determine as whether it could have happened that way, or not!
