For this period, late forties and early fifties, this kind of topic, very short, was rather interesting. Robert Baker gave it to us, among other exciting thrillers: JACK THE RIPPER, SIEGE OF SIDNEY STREET...So this one is good, no problem, taut, but if you wait a bit and watch WAIT UNTIL DARK, made in 1967, you'll quickly see the difference between those two movies. The 1967 film directed by Terence Young and also speaking of a blind lead character - Audrey Hepburn - is far far better than this one. And Henry Hathaway's 23 PACES TO BAKER STREET...But don't get discouraged, watch this one, this pretty agreeable British gem.
