A banker, Mr. Alexander Holder of Streatham, makes a loan of 50,000 to a socially prominent client, who leaves the 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 has Arthur clammed up? Why is he refusing to give a statement of any kind? How could Arthur have broken the coronet (even Holmes, who has exceptionally strong hands, can't 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 boyfriend, 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.
was a British writer and doctor known for creating the iconic fictional detective, Sherlock Holmes, and his sidekick, Dr. Watson. Before his success in writing, Doyle studied medicine at the University of Edinburgh. While attending class, he began to write short stories and submitted his work to various magazines. After numerous attempts at publication, his first story featuring Sherlock Holmes was finally published in a local journal. Soon after its release, readers began writing into the magazine begging for more stories, sparking a literary franchise that would live on to this day. The stories of Sherlock Holmes and Dr. Watson have been championed as some of the greatest mystery stories of all time, paving the way for writers of the true-crime genre for generations to come.
