I’ve actually never read any of it. Just started watching the Jeremy Brett shows a couple months ago.
I have always liked Sherlock Holmes since I saw one of the “Hound of the Baskervilles” movies as a child. Around 20 years ago I bought a thick book titled something like “The Complete Sherlock Holmes Stories”
I read them all only to discover several years later that the book did not actually have them all. I still haven’t read every single one. There really are a lot of them.
