Question about the 'half-caste.'
**Spoilers ahead***
I just finished watching Murder! for the first time. Handel Fane is "half-caste," meaning of corse he has mixed blood. I am unfamiliar with English terminology of 1930, but I was wondering if half black (as is said in the film) actually meand what it does today, or if the term "black" just meant a sort of unsavory blood line (as Irish might have been seen by the "proper" Englishman.
I believe that the term "black" when used to describe a person of African ancestry was actually seen as insulting in America in this time, and Negro was prefered. In 1930 England was this also the case? Sir John was certainly shocked by the revelation that the man he sought was "half-caste," but he didn't seem to be put off by this and his "half black" comment did not seem to be degrading or insulting in any way. In 1930 this lack of a great reaction would lead me to believe that he meant "black" as to be Irish or something similar. In much the same as a "black mark" has nothing to do with anyone of African ancestry, it is quite possible that Sir John's comment about Fane being half black may have had nothing to do with his parent's races.
This may just be a simple misunderstanding due to changing terms over decades...
