This is very good for its genre, with an interesting story, solid atmosphere, and two good leading performances from Boris Karloff and Margaret Lindsay. Made during the early part of the Second World War (when England was enduring constant air assaults and other threats), and set during the First World War, there is an obvious patriotic slant to it. But aside from a short speech by one of the characters at the end of the movie, it mostly allows the story and characters to stand on their own.
Karloff and Lindsay star as two very resourceful spies who are planted in the home of a prominent English family, with most of the story revolving around whether they are spies on behalf of England or on behalf of Germany. Karloff is, of course, especially good in a part like this, giving his character a believably ingratiating manner in his cover role as a butler, and a steely eye in his unguarded moments. He makes it easy to believe that his character can keep everyone else in the dark.
Lindsay gets one of her best roles, and she makes full use of it. Her character obviously has weapons much different from those of Karloff's character, and she too is believable in keeping the others, even Karloff, guessing.
The story moves at a good pace, and it features several good turns as it builds up the tension. Like many movies of this kind, there are places here and there where it could have been improved. In particular, its portrayal of Britain as a traitor-riddled society threatened with imminent collapse shows the strong influence of the frightening times in which it was filmed. But in its time it probably provided some genuine encouragement, and today it still remains an enjoyable movie that is well worth the time to see.
