Fishing becomes central toward the end of In Our Time. Hemingway found fishing an important element of his own life as well; he even owned his own fishing boat. For a good account of this relationship between the author's life and his work, with a collection of his works about fishing, see Hemingway On Fishing (2000). The book includes a foreword by his son Jack Hemingway and an introduction by Nick Lyons, who have elucidated this relationship.
