Jewel Cases is a collection of mystery stories by such authors as Arthur Morrison and Sir Arthur Conan Doyle. These five classic stories of varying styles all share a similar theme: jewel theft. Elegant toys. Sparkling jewels. Baubles of the idle rich. Each story presents a case of stolen valuables and pits the wits of a clever jewel thief against those of a cunning, skillful detective who is always trying to stay one step ahead of the criminal.
