"The Adventure of the Missing Three-Quarter", one of the 56 Sherlock Holmes short stories written by Sir Arthur Conan Doyle, is one of 13 stories in the cycle collected as The Return of Sherlock Holmes. It was originally published in The Strand Magazine in 1904 with illustrations by Sidney Paget.
Mr. Cyril Overton of Trinity College, Cambridge, comes to Holmes seeking his help in Godfrey Staunton's disappearance. Staunton is the key man on Overton's rugby union team (who plays at the three-quarters position, hence the story's title) and they will not win the important match tomorrow against Oxford if Staunton cannot be found.
