Hi, ChickenStu,
You've got a lot of wonderful fun ahead! Yep, you're correct about the original novels and stories. As you probably know, Doyle tired of writing Holmes and at one point thought he'd killed him off. Of course, the public clamored for more, and Doyle finally resurrected him. There are debates among Sherlockians about all manner of topics, but one is whether the post-return stories match the quality of the earlier ones. One fairly well-known comment was to the effect of, "Holmes may have returned after falling into the Reichenbach, but he was never the same fellow after that."
I've enjoyed your thoughts on the literary Bond, which set me wondering as to whether, as you read along in Holmes, you'll start having some thoughts along the same lines as these critics, or whether you'll find all the stories pretty much of uniform quality. For the record, I have my favorites, but overall I enjoy them all.
