Story
Banker Holder pledged diadem, which was the property of the nation. Fearing to leave her at his bank on , Holder takes her home in Straight and locks her in a bureau. At night, he discovers Arthur’s son near the bureau with a bent diadem, which also has a missing part, but the banker's niece Mary claims that his son is innocent. Police arrest Arthur for lack of other suspects. Holder goes to Holmes . Holmes finds that Mary was an accomplice to the theft committed by her lover, George Burnwell. Arthur, on the other hand, took most of the diadem from Burnwell and actually returned it to its owner. Arthur, who loved Mary, refused to talk about the true circumstances of the theft, since he could justify himself only by accusing Mary. In the end, Holmes, going to Burnwell, finds out from him the location of the missing piece of the diadem and redeems it.
