Book excerpt: It was a cold, "windless, blue sky day" in the fall of 1939 near Silver Creek--a blue-ribbon trout stream south of Sun Valley. Ernest Hemingway flushed three mallards and got each duck with three pulls. He spent the morning working on his novel For Whom the Bell Tolls. Local hunting guide Bud Purdy attested, "You could have given him a million dollars and he wouldn't have been any happier." Educator Phil Huss delves into previously unpublished stories about Hemingway's adventures in Idaho, with each chapter focusing on one principle of the author's "Heroic Code." Huss interweaves how both local stories and passages from the luminary's works embody each principle. Readers will appreciate Hemingway's affinity for Idaho and his passion for principles that all would do well to follow.
