We finished reading "Hound of the Baskervilles" together, and my nearly 8yo daughter loved the entire thing.
We just watched a B&W version with Basil Rathbone as Holmes, and also an 80's version with Jeremy Brett. We have watched each several times. We have had many conversations about the different versions, and how they differ from the story.
Now she is wanting another Holmes mystery. The question is: which one? She liked this one in part because of the hound, if that helps. I don't mean necessarily chronological. I think The Hound is the 2nd Holmes novel.
I posted this in Books and Media yesterday, but no replies yet. So, I bring it here.
