Whose perspective is missing? In Sherlock Holmes, oh, it's everything. Every single person in a chapter, usually.
In the book, the beginning starts with both Sherlock Holmes and Dr.Wattson's perspectives, each voice starting at a fresh, new chapter. However, around the middle of the book, you only hear Dr.Wattson speaking. This leaves with Sherlock Holmes out, and Wattson with more thinking. This then leaves with Sherlock Holmes' perspective missing.
In my opinion, I think that Conan Doyle, the author of this text, excludes Sherlock Holmes' voice because Sherlock Holmes is the one who solves every case! He's the one figuring out about 90% of his cases. If you add his perspective back in the story, the solution to the case will be there before he even explains it! It also seems like the author wants to exclude his part in the story to give readers more deeper thoughts and chances for theories.
Because Sherlock Holmes' perspective is missing, the one that stands out, Dr.Wattson's perspective, gives a more normal start. Dr.Wattson is often curious and wants to know more about Sherlock Holmes. This is much like Curious George, only the settings are different and George is...a monkey.
Current points of view are better than having Holmes' perspective around because it'll lessen the spice and adventure, and adding Holmes' thoughts is much like a spoiler that's occurring in the book.
