I’ll come right out and say it: blackface is a central part of this story. This novel is from 1934 when white people didn’t blink at blacking up and performing music as “n****r minstrels”. There’s simply no way to edit this story to exclude this fact without greatly changing the story.
I’ve only read Jeeves short stories to now; this is the first novel (and Wodehouse’s first Jeeves novel too). It hangs together, the plot is clever and of course Jeeves saves the day. Satisfying, but hold your nose.
