Green Hills of Africa (1935) is Ernest Hemingway's second book of non-fiction concerning a blood sport. The book was occasioned by an African safari the author took with his second wife, Pauline Pfeiffer Hemingway, in 1933-1934. In a brief foreword, Hemingway called the book a novel based on real people and actual events (i.e., what has come to be known as a 'non-fiction novel'). Much as Henry David Thoreau had altered time sequences, compressed events, and inserted meditative passages in books such as Walden, Hemingway altered the facts of his hunting trip, built suspense by using novelistic techniques, and employed the book as a vehicle for his thoughts on various matters, principally writing.
