The case against Arthur seems rather damning, yet Holmes is not convinced of his guilt. Why is Arthur refusing to give a statement of any kind? How could Arthur have broken the coronet (even Holmes, who has exceptionally strong hands, cannot do it) and without making any noise? Could any other people in the household be involved, such as the servants, or Mary? Could some visitor, such as the maid's wooden-legged suitor, or Arthur's rakish friend Sir George Burnwell, have something to do with what happened to the coronet? The failure to resolve the case will result in Mr. Holder's dishonour, and a national scandal.
