Hervé lost a leg in a motorbike accident. On the eve of the operation, he made a deal with God: “If I walk again, I'll go to Santiago.” He did walk again, but not on pilgrimage. Instead, he got caught up in his business affairs, had a burn out, tried to kill himself and spent several months in a psychiatric hospital before he decided to keep his side of the bargain. He set out, with crutches and a prosthetic leg, for Santiago de Compostela, a journey of 1,920 kilometres from his home in Brittany in north west France to the cathedral that contains the relics of Saint James at the tip of north west Spain. John Laurenson walks with him for a couple of days to hear his story and talk about life, God, pilgrimage.
