Sherlock Holmes and Watson are hunting in couples again. They have been introduced to Mr. Merryweather, the man who will be their companion for tonight's adventure. John Clay is a young man but he is at the head of his profession; I would rather have my bracelets on him than any criminal in London. For you, Mr. Jones, it will be the man upon whom you wish to lay your hands. The stake will be some thirty thousand pounds.
