If you like 'Pool of London' you'll like this
This is a good solid British 40s crime thriller similar to 'Pool of London' or 'The Blue Lamp'.
It also has a nice though somewhat unbelievable love story, and lots of location shots of 1940s London, rather unusual for an era when most films were studio-bound.
The propaganda over the need for wartime deserters to hand themselves in is a little heavy handed in places, but overall it's worth the watch.
