Hemingway worked on For Whom the Bell Tolls during his first stay at Sun Valley Lodge in 1939. His later Ketchum years left less work but more lore, and the local literary record is mostly his.
Papa Hemingway — Hotchner was a young magazine editor who became Hemingway's fishing companion, ghostwriter, and friend for the last decade of his life. The memoir tracks them from Cuba through Spain to Ketchum, and the final chapters in Idaho are some of the most painful and clear-eyed writing about the writer's decline.
For readers visiting Sun Valley, the Ketchum sections give specific addresses, restaurants, and bars that you can still walk past. The Pioneer Saloon and the road up to the hunting cabin at Silver Creek are exactly where Hotchner left them.
