Mentioned in other stories
Mary Watson (née Morstan) was the wife of Dr John Watson. She is first introduced in The Sign of Four and Watson refers to her in a number of the stories. While she is generally not involved in the main action of most stories, she is a central character in The Sign of Four.
Mary's father, a senior captain of an Indian regiment and later stationed near the Andaman Falls, disappeared mysteriously in 1878 which would prove to be related to the mystery in The Sign of Four. Mary Morstan is Holmes' client in this story, and Watson describes her at their first meeting this way:
"She was blonde young lady, small, dainty, well gloved, and dressed in the most perfect taste. Her face had neither regularity of feature nor beauty of complexion, but her expression was sweet and amiable, and her large blue eyes were singularly spiritual and sympathetic."
Watson and Morstan fall in love during the course of the story. Watson initially hides his feelings for Morstan because she stands to inherit a fortune, and he sees it as improper and unethical to court her in view of her financial prospects. When the treasure is lost, they both admit feelings of relief and confess their love for each other.
In 2014, she was introduced in the BBC televised version of Sherlock in "The Empty Hearse", in which she is portrayed by Amanda Abbington, the real-life partner of Martin Freeman, who plays Watson in the series.
