The Mystery of Mallory and Irvine examines one of mountaineering’s greatest enigmas: the final 1924 expedition of George Mallory and Andrew Irvine on Mount Everest, who disappeared near the summit and were never seen alive again. The authors explore archival records, eyewitness accounts, and expedition evidence to ask whether they might have reached the top decades before Hillary and Tenzing — and what actually happened on that fateful climb. Combining historical research, personal expedition experience, and expert analysis, the book delves into mystery, myth, and the enduring allure of Everest.
