Violet Smith, a young music teacher, reached out to Holmes. She was worried because she noticed someone stalking her on her everyday bicycle ride to the train. Holmes took up the case and found out that Violet's life had changed drastically a few months ago when two friends of her distant uncle arrived in Surrey. Could this event have something to do with Violet's stalker? Is there some connection between the sudden interest that both of them had in Violet and the deteriorating health of her uncle? "The Adventure of the Solitary Cyclist" is a part of "The Return of Sherlock Holmes".
