A digest of the news of the week plus a visual commentary for those who cannot hear, with Kenneth Kendall

This programme traces an unsolved mystery set against the exotic background of Bangkok. The story of an ex-CIA man, famous as the Thai Silk King, who revitalised the dying craft of silk weaving and built it into a multi-million dollar industry. Jim Thompson disappeared in 1967 while holidaying in Malaysia. His unique house on the Klong remains a landmark in Bangkok.

Extensive searches have so far failed to discover any clues or information concerning his disappearance. However, theories abound - was he kidnapped... or murdered? Did he vanish on purpose? Or was there another reason for the disappearance of this strange man?

'Questioning,' said Dr Johnson, 'is not a mode of conversation among gentlemen.'
