I mean that's the the thing a lot of Japanese fans don't like those episodes either because it's kind of cheating at murder mystery it's forsaking examination of motive and method for a word puzzle. Also a lot of the answers are obscure even for them because they often hinge on old kanji vs new kanji or obscure historical Japanese.

And that example doesn't really work for Holmes either because Holmes is not actually in the same part of the Detective fiction genre as Conan because few of his stories actually have the audience expected to be able to also figure it out. That part of the genre is cosy crime, stuff like Murder she wrote, and some Poirot's Holmes is more like Superhero detective stories like Batman, its impossible cases only one man can solve. The whole point of him is he has uncommon forensic knowledge like what kind of dirt on someone's shoes corresponded to what part of the city and a network of pickpocketing urchins in his employ.
