Chavasse wore a sheepskin shuba wrapped closely around him, sheepskin boots and a hat of some indeterminate fur, flaps down over his ears. He cradled a British Lee Enfield rifle in one arm and allowed the hardy mountain pony to find its own way. He thought he heard a plane at one point, but could not be sure as the sound faded rapidly.

The Land of Snows the Tibetans called this part of the border area, and it was well named, a living nightmare of a place with passes through the mountains as high as twenty thousand feet. It was not uncommon for mules in the caravans in the old days to die of asthma and for their masters to get pulmonary edema as their lungs filled with water.

An ironic way to die, Chavasse thought, to drown while standing up. Of course, it didn’t matter these days. There were no more caravans to India, by Chinese decree.

It started to snow again lightly and he paused to check the ground ahead. The sky being blanketed by low swollen clouds, there was no snow glare. He had spent the previous night in a herdsman’s cave, sheltering from a sudden blizzard, and had started again at first light. Now, the pass between the peaks emptied onto a final slope that ran down towards the Indian border. In fact, in the far distance there was a flicker of colour, obviously a flag, and Chavasse urged his pony forward.
