The definitive book on Sandy Irvine and the mystery of his and Mallory’s disappearance on Everest in June 1924. The fate of George Mallory and Sandy Irvine, who were last seen disappearing into the clouds as they headed for the summit of Mount Everest on 8 June 1924, still grips the imagination over 100 years later. Mallory’s body was found in 1999 and Sandy Irvine’s boot and foot were discovered in 2024, becoming an international news story. Drawing on previously unpublished material and new discoveries, Irvine’s great-niece Julie Summers and mountaineering historian Jochen Hemmleb (who was part of the team that found Mallory’s body) have written the definitive account of the expedition from twenty-two-year-old Sandy’s perspective, challenging misconceptions about his role. They also bring to life all the remarkable characters involved in the attempt on Everest and reveal fascinating discoveries about what really happened on the men’s final climb. Beautifully written, The Everest Mystery is a powerful story of adventure and courage – and an intriguing detective story.
