the woman in green (1945)

aka Sherlock Holmes and the Woman in Green.
"What are you looking at, Mr. Holmes?"
A serial killer is killing women and cutting off their thumbs, but with Sherlock Holmes on the case, you know that this will be anything but a run of the mill killer.
Another in the series, in which Rathbone gives a dry performance as Holmes, contrasted by the buffoonery of Nigel Bruce as Dr Watson. Otherwise this is a run of the mill outing for the duo.
