Q:Question: Who visits Holmes and Watson? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: The Adventures of Sherlock Holmes Context: The picture begins with Moriarty and Holmes verbally sparring on the steps outside the Old Bailey where Moriarty has just been acquitted on a charge of murder due to lack of evidence. Holmes remarks, "You've a magnificent brain, Moriarty. I admire it. I admire it so much I'd like to present it, pickled in alcohol, to the London Medical Society". "It would make an impressive exhibit", replies Moriarty. Later Holmes and Watson are visited at 221B Baker Street by Ann Brandon (Ida Lupino). She tells him that her brother Lloyd has received a strange note - a drawing of a man with an albatross hanging around his neck - identical to one received by her father just before his brutal murder ten years before. Holmes deduces that the note is a warning and rushes to find Lloyd Brandon. However he is too late, as Lloyd has been murdered by being strangled and having his skull crushed. Holmes investigates and attends a garden party, disguised as a music-hall entertainer, where he correctly believes an attempt will be made on Ann's life. Hearing her cries from a nearby park he captures her assailant, who turns out to be Gabriel Mateo, out for revenge on the Brandons for the murder of his father by Ann's father in a dispute over ownership of their South American mine. His murder weapon was a bolas. Mateo also reveals that it was Moriarty who urged him to seek revenge. Holmes realises that Moriarty is using the case as a distraction from his real crime, a crime that will stir the British Empire - an attempt to steal the Crown Jewels. Holmes rushes to the Tower of London to prevent the crime, and during a struggle Moriarty falls, presumably to his death. In the end, Ann is married and Holmes tries to shoo a fly by playing his violin, only to have Watson swat it with his newspaper remarking, "Elementary, my dear Holmes, elementary."[3]
