Nigel Patrick ("Kenyon") works quite well here as a customs and excise inspector who is on the trail of a glamorous brother and sister (Elizabeth Sellars & Terence Morgan) whom he and boss Jack Warner suspect might be involved in a big drug smuggling enterprise. As the plot thickens, he begins to fall a little for the femme fatale and things all get rather too complicated. It features a fun contribution from Joyce Grenfell as the slightly eccentric tweeter (birds) "Lady Flavia' and keep an eye out for a fleeting visit by Michael Hordern. The writing is a bit bland however, and the investigative sides of the story a bit procedural - but the performances are decent enough and the photography helps the drama along well. Worth a watch.
