He was played by Mark Bonnar in the 1997 radio adaptation of "The Valley of Fear" in the 1989–1998 BBC Radio series. MacDonald is played by Dennis Bateman and David Natale in the American radio series "The Further Adventures of Sherlock Holmes", in which he is a recurring character. Mary 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 blonde with pale skin. At the time she hires Holmes she had been making a living as a governess. Although at the end of the story the main treasure is lost, she has received six pearls from a chaplet of the Agra Treasure. 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 received wisdom of the time about children in the colony of India) until the age of seventeen. Shortly afterwards her father disappeared and she found work as a governess. Watson and Mary marry 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. Leslie S. Klinger writes that there appear to be contradictions regarding Mary Morstan between the stories. According to Morstan in "The Sign of the Four", which likely takes place in summer 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, though Klinger suggests they indicate that Watson had a wife who preceded Mary Morstan and died before 1888. Mary Morstan has been portrayed on film and television by several actresses. In many cases, her role is expanded in new stories. Langdale Pike is a celebrated gossipmonger whose columns are published in numerous magazines and newspapers (referred to as the "garbage papers" by Watson).
