While interesting for the footage of London circa 1954, this is an absurd movie. The story line is almost impossible to follow. There's almost no dramatic tension. The situations and supposed relationships are so unrealistic that even willing suspension of disbelief doesn't work. The protagonist is gullible and hard to swallow as a supposed tough guy when he spends so much time playing the fool to beautiful women and whimpering like a small boy to his mother, etc. And to top it off, it really doesn't strike me as a film noir at all, just a confusing murder mystery. The best thing about it is Belinda Lee, previously unknown to me, a beautiful woman who was killed a few years later, at 26, in a California car accident.
