The James Bond films of the early 1960's were a combo of hard, exciting action; flirting and sexy women; some witty dialogue; interesting worldwide locations; and a look of big money on the screen, to sell it all. TV shows have never been able to really match all those elements, so they would pick and choose. That's this episode.
Alan Caillou, who wrote this and 6 other episodes, had a real life background of WWII intel work plus a police career in Africa. He had plenty of background to write realistic action if he wanted. Here he goes for humor and romance. Some familiar faces make this an especially fun show for we old TV hands: Glenn Corbett as an adventurous Yank tourist; Karen Sharpe as a very sexy, mysterious lady; Gavin McLeod as a bad guy; and Richard Kiel, pre-Bond films, as a henchman. Some fans, I think, yearn for the series to always lean more towards action and danger, but UNCLE always tried to have the witty, sexy aspect of some spy films. That's central to the series, as it is here. Karen and Glenn really shine in this outing.
