Arun Lilly (Lords and Ladies)
I spotted this pair returning home from a ball. Both look 'not at their best', usually this is through too much drink. She seems to have damaged her shawl, while he appears to be nodding off. I hope they got home safely!
If you have read the 1933 book, you know Shangri-La. Tibetans live in this part of China. The mountain is called Meili (6740 meters above sea level), which is one of the eight sacred mountains in the Tibetan Buddhism.
