I've been reading Sherlock Holmes stories to Emma while she knits—yes, we can be astonishingly domestic—and most of them I find entertaining for the Holmes-Watson dialogue, but the plots tend to be obvious or ludicrous or both. But "The Yellow Face" is different. I don't want to spoil it by saying why, though there's one thing I'll mention that should be obvious to any discerning reader: when Holmes shares his theory before he has a chance to prove it, you know his theory is wrong.
And while it's great to have a story where Holmes is wrong, Holmes being wrong is not why this story is great.
If you google it, you might get spoiled, so here's a link to Project Guttenberg's online copy: Memoirs of Sherlock Holmes, by Sir Arthur Conan Doyle: Adventure II. The Yellow Face.
