It's one of those old B pictures with a lot of location shooting in London, which now makes for rather more compelling viewing than the film itself (which is very similar in feel and treatment to Sidney Lumet's altogether superior "The Deadly Affair" from five years later).
The cinema which features extensively and in which one of the spies meets his end is neither of those mentioned in previous reviews. It is actually the Grange Cinema on High Street KIlburn, dating from 1914 and Grade II listed, as a result of which is therefore still there, albeit now functioning, as so many do, as a third-world evangelical church.
