Sherlock Holmes and the Secret Weapon

Sherlock Holmes and the Secret Weapon (1942) is a wartime detective thriller you can watch online on iFILM, with Basil Rathbone and Nigel Bruce as Holmes and Watson. The story opens in Switzerland: Holmes smuggles a Swiss inventor out from under the Gestapo before they can seize his newly designed bomb-sight, an instrument the Allied forces urgently need.

Back in London, the inventor vanishes. He leaves behind an encrypted message — the only thread connecting Holmes to his whereabouts. Lionel Atwill plays Professor Moriarty, who has his own plans for the device.

Made in 1942 at Universal, the film consciously updates Conan Doyle's character into a wartime operative. It is a brisk 68 minutes of espionage plotting, code-breaking, and the old Holmes–Moriarty rivalry dressed in WWII context. Stream Sherlock Holmes and the Secret Weapon (1942) online on iFILM.
