The authors try and uncover the mystery behind Patton's strange and sudden death. It seems that the General was on the hit list of not only the Nazis, who regarded him as a superlative military commander but also Russians and some clandestine US Govt agencies. The reason why the latter wanted Patton dead was because by the end of the war Patton's status had grown legendary and he was planning to ascend to important political offices, but his view did not fit the new political views especially of some of his peers and these Govt agencies.
There is some genuine evidence brought forward by Bill and Martin which indicates foul play in the car accident which lead to the death of Patton. I'm not sure what the governments response has been? This incident is reminiscent of the mysterious death of another military leader SC Bose, post the second world war.
