Larry,
I've finished your book. Great stuff. I have a question about Johnson, but not Lyndon Baines.
In the Hargraves interview in your book, they talk about Robert Evan Johnson as someone who may have important papers, on stuff "that nobody ever even thought to cover up" (p. 277). Hemmings is said to believe that Johnson was the famous "Raoul" in the King assassination. Johnson was also involved with Hall and Sturgis in "burning" Hemmings's Dallas connections (p. 279). Hargraves says that Johnson's files would lead to one Rita Wilson, "who has the pictures of just about everyone in the camp in those days" (p. 305).
So my question is, what do we know about this Robert Evan Johnson with this treasure trove of stuff, a character I had never heard of till reading your book? I've looked for him in other books, but the closest I've found is Robert Emmett Johnson in the book Deadly Secrets. This Johnson was "a paramilitary journalist and mercenary schemer who had once been on Trujillo's payroll" (p. 291). And coincidentally (?) he worked in Montreal with a man named Raul Dagnais, in a plot against Duvalier.
