This is another in the "Columbia Screen Classics By Request" DVD-R series. It's a great suspenser about a Nazi spy ring operating in the U.S. during WW2. Director Menzies also worked as an art director on many great films, but had a mixed record as a film director. This is one of his better efforts. Great transfer, restored to near pristine condition by Sony. I fear that this series of lesser-known titles from Columbia is failing. They've recently taken down the "Classics By Request" area on the Sony Pictures site and I haven't noticed any new releases in the last couple of months. Get these now before they disappear!
