Yesterday I was quite lucky by watching on YouTube a 1953-movie called "Operation Diplomat" and I instantly recognised the actress Patricia Dainton and that was lucky because she is one of the main characters in "The Third Alibi" (1961), a classic movie I have tried to find for many years, as it is one of the very best thrillers with many logical twists and turns ... and where the very best English is spoken as well ... and hopefully it remains there to be watched for free, because there is already someone on YouTube trying to "make money" with it ....
