What is the correct order of Sir Arthur Conan Sherlock Holmes novels?

Sir Arthur Conan Doyle wrote four novels and 56 short stories featuring Sherlock Holmes. Here's the correct order of the novels, with the year of publication in parentheses:

1. A Study in Scarlet (1887)

2. The Sign of Four (1890)

3. The Hound of the Baskervilles (1902)

4. The Valley of Fear (1915)

Note:

* The novels are listed in the order of their original publication, not necessarily the order in which the events happen in the stories.

* While "The Hound of the Baskervilles" is considered to be one of the most famous Sherlock Holmes novels, it was actually the third one published.
