is the fifth film in the
Basil Rathbone/Nigel Bruce series of
Sherlock Holmes movies.
A British agent carrying a vital document is murdered on his way to deliver it in the USA. Holmes deduces he was carrying the document in the form of
Microfilm and goes to Washington with Watson to find the killer and retrieve the document. Before his death, the agent manages to pass the microfilm into the unwitting hands of a Washington debutante and bride-to-be. There are some amusing moments when the microfilm, which has been inserted into a "V for Victory" match folder, gets passed from hand to hand at a party unknowingly, and at one point is discarded by the chief criminal. Another World War II
Cliche comes into play in the form of the Washington housing shortage, meaning that the debutante, rolled up in a rug, can be smuggled out of the apartment in her parents' home that's being renovated for her. Holmes and Watson track down the criminals, rescue the bride-to-be and regain the microfilm.
