Actually, O’Reilly used that theory as the “McGuffin” for his “Killing Patton” book. If one reads it to the end, or just the last chapter, you will find out that he totally discards it and lays out how the accident happened and how it could not have been a planned murder. The key point being that Patton made to decision to go pheasant hunting early in the morning of Dec 8. He told his driver to get the sedan and guns ready and asked BG Hobart Gay to accompany him.
Interesting. I had forgotten that as I gave the book away.
