Did you know that Hemingway tried to commit suicide twice before he succeeded on July 2, 1961? The first time his wife, Mary, caught him with a gun in their kitchen. The second time was when the plane he was riding in stopped in Casper, Wyoming for repairs. He tried to walk into the moving propeller. He was suffering from depression and paranoia and was being admitted to the Mayo Clinic in Minnesota. He thought the “Feds” were tailing him and were out to get him.
In actuality, J. Edgar Hoover had Hemingway placed under surveillance because he was suspicious of his activities in Cuba. Maybe Hemingway knew this and maybe he wasn’t as paranoid as everybody thought.
