On June 8, 1924, George Leigh Mallory and Andrew Irvine disappeared somewhere near the summit of Mount Everest, leaving open the tantalizing question of whether they had reached the summit of Everest twenty-nine years before Edmund Hillary and Tenzing Norgay. In 1999, climber Conrad Anker discovered Mallory's body on Everest and helped solve one of the greatest mysteries in the history of adventure and exploration. In "The Lost Explorer," Anker and historian David Roberts craft a dramatic account of the expeditions of 1924 and 1999, and ultimately capture the passion and spirit of two men driven to test themselves against nature at its most brutal.

1924年6月8日，乔治-利-马洛里和安德鲁-欧文在珠穆朗玛峰山顶附近的某个地方失踪，留下了一个诱人的问题：他们是否比埃德蒙-希拉里和丹增-诺尔盖早29年到达珠穆朗玛峰山顶。1999年，登山者康拉德-安克尔在珠穆朗玛峰上发现了马洛里的尸体，并帮助解开了冒险和探险史上最大的谜团之一。在《失落的探险家》中，安克尔和历史学家大卫-罗伯茨对1924年和1999年的探险活动进行了戏剧性的描述，并最终捕捉到了两个人的激情和精神，他们在最残酷的自然环境中测试自己。
