In The Beckoning Silence, Joe Simpson - whose amazing battle for survival featured in the multi-award winning Touching the Void - travels to the treacherous North Face of the Eiger to tell the story of one of mountaineerings most epic tragedies.
As a child, it was this story and that of one of the climbers in particular, that first captured Simpsons imagination and inspired him to take up mountaineering.
Toni Kurz was a brilliant young mountaineer, who along with three other climbers tried to climb the mountain in 1936, which was then the last great unconquered peak in the Alps.
Their assault on the mountain started well, but then disaster struck. One by one Kurzs colleagues were killed, leaving him alone, hanging on the end of a rope fighting for his life in the most horrific of circumstances.
Over 50 years later in Peru, Kurzs story haunted Simpson as he battled for his own survival while hanging in mid-air. His plight uncannily mirrored that of Kurz - except, against all the odds, Simpson lived whilst his hero had perished.
