POLO [OC]: Success. My plan has worked. The strangers and their unusual caravan accompany me to Lop. Our route takes us across the Roof of the World, down to the Kashgar Valley and southeast to Tarkand. Here we join the Old Silk Road, along which the commerce and culture of a thousand years has travelled to and from Cathay. I wonder what the strangers' reaction will be when I tell them what I propose to do?
