It may be my age, but this gem could not have come at a better time of year (winter). With a rainy afternoon outside, no interruptions and my mind reset back to darker, more paranoid times, this black and white thriller delivers solid entertainment and pleasure.
My total lack of knowledge of it before watching - how have I missed it on TV? - added an extra sense of tension. I've now become a bit of a missionary, passing it on for others to enjoy.
The great cast is also worth a mention with familiar old faces popping up all the way through.
