The Man Who Was Sherlock Holmes - 1937 - 6/10
AKA - Der Mann, Der Sherlock Holmes War

Two men halt the midnight train, then climb aboard.
One carries a violin case and smokes a pipe, the other seems a medical man.
The conductor and guards immediately jump to the conclusion, “This is Sherlock Holmes!”
Not necessarily, though the pair exploit the misassumptions constantly.
They are sucked into a “Russian Dolls” mystery within mystery within mystery.
Brisk comedy, thriller is quite fun, and despite being a Reichsfilme, strikes me as propaganda free.
