De Mohrenschildt was the key to the whole deal, the only thing keeping me from killing Oswald as soon as he moved in across the street. George de Mohrenschildt, a petroleum geologist who speculated in oil leases. A man who lived the playboy lifestyle, mostly thanks to his wife’s money. Like Marina, he was a Russian exile, but unlike her, from a noble family—he was, in fact, Baron de Mohrenschildt. The man who was going to become Lee Oswald’s only friend during the few months of life Oswald had left. The man who was going to suggest to Oswald that the world would be much better off without a certain racist right-wing ex-General. If de Mohrenschildt turned out to be part of Oswald’s attempt to kill Edwin Walker, my situation would be vastly complicated; all the nutty conspiracy theories would then be in play. Al, however, believed all the Russian geologist had done (or would do; as I’ve said, living in the past is confusing) was egg on a man who was already obsessed with fame and mentally unstable. Al had written in his notes: If Oswald was on his own on the night of April 10th, 1963, chances that there was another gunman involved in the Kennedy assassination seven months later drop to almost zero.
