Thanks to some new channels on satellite we are now able to view again many British crime thrillers from the 40s and 50s which were last shown on BBC or ITV about 30 years ago.What is often most interesting about these films is the location shots,so that you can compare London of that era with the London of today.The film is full of actors familiar from that period,including one of my favourite actors of that time Eric Pohleman.He really was a superb villain.The fact that he had a continental accent meant that this made him sound even more sinister to the post war audiences.Also featured is Michael Brennan who must have beaten up more leading men than he had hot dinners.Kynaston Reeves who usually played Judges has a longer part than usual.In all a reasonably entertaining thriller
