The banker Alexander Holder has been the victim of a theft and his son Arthur has been caught red-handed. An important client had entrusted Alexander with the Beryl Coronet – a rare and precious piece of jewellery – in exchange of a £50,000 loan. Not wanting to risk leaving it at the bank, Holder had taken it back home. He’d been awoken at night by a noise and had discovered his son, coronet in hand, and three of its beryl were missing. Yet Sherlock Holmes, hired by Holder, doesn’t seem to think that Arthur is guilty.
“The Adventure of the Beryl Coronet” is part of “The Adventures of Sherlock Holmes”.

Sir Arthur Conan Doyle (1859-1930) was born in Scotland and studied medicine at the University of Edinburgh. After his studies, he worked as a ship’s surgeon on various boats. During the Second Boer War, he was an army doctor in South Africa. When he came back to the United Kingdom, he opened his own practice and started writing crime books. He is best known for his thrilling stories about the adventures of Sherlock Holmes. He published four novels and more than 50 short-stories starring the detective and Dr Watson, and they play an important role in the history of crime fiction. Other than the Sherlock Holmes series, Doyle wrote around thirty more books, in genres such as science-fiction, fantasy, historical novels, but also poetry, plays, and non-fiction.
