Found an article stating that Ernest Hemingway had been
a spy for the KGB.
"Hemingway is believed to have purchased the Boss & Co. shotgun he used to commit suicide through Abercrombie & Fitch, which was then an elite excursion goods retailer and firearm supplier. In a particularly gruesome suicide, he rested the gun butt of the double-barreled shotgun on the floor of a hallway in his home, leaned over it to put the twin muzzles to his forehead just above the eyes, and pulled both triggers. The coroner, at request of the family, did not do an autopsy."
