The Adventure of the Beryl Coronet

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. "The Adventure of the Beryl Coronet", one of the 56 short Sherlock Holmes stories written by British author Sir Arthur Conan Doyle, is the eleventh of the twelve stories collected in The Adventures of Sherlock Holmes. The story was first published in Strand Magazine in May 1892.
