The Yellow Scarf Affair

Solo goes to India to investigate the death of a fellow U. N. C. L. E. agent in an airline crash, and discovers that a cult of Thuggees headed by a maharajah (Murray Matheson) is causing the crashes in order to loot the passengers. But Solo and THRUSH agent Tom Simpson (Linden Chiles) are looking to recover one item in particular - U. N. C. L. E.'s new polygraph device.
