Sherlock Holmes, the famous detective created by Sir Arthur Conan Doyle, does not have a wife in the traditional sense. Throughout the stories, Holmes is known for his single, bachelor lifestyle, primarily focusing on his detective work and his close friendship with Dr. John Watson.
There is, however, one character named Mary Morstan, who later becomes Dr. Watson’s wife. Some adaptations and modern interpretations of the Sherlock Holmes stories have playfully explored the idea of a romantic relationship between Holmes and other characters, but in the original canon, Holmes remains unmarried. This aspect of his character underscores his dedication to his work and his lack of interest in domestic life.
