Mary Watson, née Morstan, is the wife of Dr. Watson. She is first introduced in The Sign of the Four, where she and Watson tentatively become attracted to each other, but only when the case is resolved is he able to propose to her. She is described as a blonde with pale skin who had been making a living as a governess. She hired Holmes to solve the mystery of her father's disappearance, which led to the mystery of the Agra Treasure. At the end of the story the main treasure is lost - rather to Watson's relief, since if she had been a rich heiress, his proposing to her might have been considered the act of a fortune hunter. From the entirety of the Agra Treasure, six pearls from a chaplet are in her possession.

Her father, Captain Arthur Morstan, was a senior captain of an Indian regiment and later stationed near the Andaman Islands. He disappeared in 1878 under mysterious circumstances that would later be proven to be related to the mystery, The Sign of the Four. Her mother died sometime before 1878 and she had no other relatives in England, although she was educated there (in accordance with the practice of the time about European children in British-ruled India) until the age of seventeen. Shortly afterwards, her father disappeared and she found work as a governess. Watson and Mary married in 1889.

Mary Morstan is mentioned in passing in "The Adventure of the Crooked Man" and "The Boscombe Valley Mystery", but by the time of "The Adventure of the Norwood Builder" (after Holmes's return) Mary Morstan has died and Watson has returned to his former lodgings in Baker Street. Her cause of death is never mentioned.

According to Morstan in The Sign of the Four, which probably takes place in the summer of 1888, her mother died many years ago and she has no relatives in England. However, in "The Five Orange Pips", which is explicitly dated by Watson in September 1887, Watson is already married, and is again in Baker Street because his wife was "on a visit to her mother's". These discrepancies may be errors, but it may indicate that Watson had a wife who preceded Mary Morstan and died before 1888.
