"The Adventure of the Beryl Coronet", one of the 56 short Sherlock Holmes stories written by Sir Arthur Conan Doyle, is the eleventh of the twelve stories collected in The Adventures of Sherlock Holmes. The story was first published in The Strand Magazine in May 1892. Plot A banker, Mr. Alexander Holder of Streatham, makes a loan of £50,000 (equivalent to approximately £ in ) to a socially prominent client, who leaves a beryl coronet—one of the most valuable public possessions in existence—as collateral. Holder feels that he must not leave this rare and precious piece of jewellery in his personal safe at the bank, and so he takes it home with him to lock it up there. He is awakened in the night by a noise, enters his dressing room, and is horrified to see his son Arthur with the coronet in his hands, apparently trying to bend it. Holder's niece Mary comes at the sound of all the shouting and, seeing the damaged coronet, faints dead away. Three beryls are missing from it. In a panic, Mr. Holder travels to see Holmes, who agrees to take the case. 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, can barely 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. Holmes sets about not only reviewing the details that he learns from Holder but also by examining the footprints in the snow outside. Eventually, Holmes solves the mystery, and Holder is flabbergasted to find that his niece was in league with a notorious criminal (Sir George Burnwell), although apparently, she is unaware of his character. The two of them escape justice; however, Holmes is convinced that they will receive their punishment in due time. Arthur's motive in allowing his father to think he was the thief was that he was in love with his cousin Mary and saw her passing the coronet to Burnwell
