Mary Sutherland visits Sherlock Holmes, distressed because her fiancé, Hosmer Angel, disappeared on the day of their wedding. She tells Holmes that Hosmer was shy, wore tinted glasses, and only communicated with her through typewritten letters. Holmes quickly becomes suspicious and investigates. He deduces that Hosmer Angel never existed as a real person. He concludes that Mary's stepfather, Mr. James Windibank, invented the identity of Hosmer Angel to keep her from marrying and leaving home because if she moved out, he would lose access to her income. Holmes exposes the deception but decides not to tell Mary the full truth, believing she would not accept it.

For our final project, we were asked to write our own detective story. We had to create an original mystery with interesting characters, clues, and a suspenseful plot. We had build a case, plant hints, and craft a satisfying solution that ties everything together. The goal was to practice creative writing skills while exploring how detectives solve crimes through observation, reasoning, and deduction.
