Dr Tobel (William Post Jr) has developed an advanced new bomb sight, Sherlock Holmes (Basil Rathbone) helps bring Tobel to the UK and away from the clutches of the Gestapo. It should all be simple and settled now right?
Unfortunately not as Tobel has a rather lax attitude to his own personal safety, and the dreaded Professor Moriarty (Lionel Atwill) is after the bomb sight and is willing to sell them to the Nazis...
An excellent "modern" Sherlock Holmes tale, Basil Rathbone and Nigel Bruce as Watson bringing all the goods as usual. Fast moving plot and ingenious code driven action makes this film highly enjoyable.
