IN the early 1920s Ernest Hemingway was a little-known journalist slumming around Europe and getting into absinthe-fuelled scrapes. Then, a century ago, in 1925, he published “In Our Time”, a book of short stories; in July of that year he started working on “The Sun Also Rises”, his first novel, which fictionalised his antics. It became the most celebrated book about the “Lost Generation” in post-war Europe.
