Lore & Background

Watson's journey begins in the aftermath of the Second Anglo-Afghan War, where he is wounded at the Battle of Maiwand. Seeking recovery in London, he meets Sherlock Holmes through a mutual acquaintance, leading to their shared tenancy. Watson is intelligent, if lacking Holmes's insight, and serves as a foil for the brilliant, emotionally detached detective. In The Sign of the Four, Watson becomes engaged to Mary Morstan, a governess.
