Next day Simon Carne was the recipient of an invitation to the ball in question, and two days later he called upon the Duchess of Wiltshire, at her residence in Belgrave Square, with a plan prepared. He also took with him the small vase he had promised her four nights before. She received him most graciously, and their talk fell at once into the usual channel. Having examined her collection, and charmed her by means of one or two judicious criticisms, he asked permission to include photographs of certain of her treasures in his forthcoming book, then little by little he skillfully guided the conversation on to the subject of jewels. "Since we are discussing gems, Mr. Carne," she said, "perhaps it would interest you to see my famous necklace. By good fortune I have it in the house now, for the reason that an alteration is being made to one of the clasps by my jewellers." "I should like to see it immensely," answered Carne. "At one time and another I have had the good fortune to examine the jewels of the leading Indian princes, and I should like to be able to say that I have seen the famous Wiltshire necklace." "Then you shall certainly have the honor," she answered with a smile. "If you will ring that bell I will send for it." Carne rang the bell as requested, and when the butler entered he was given the key of the safe and ordered to bring the case to the drawing-room. "We must not keep it very long," she observed while the man was absent. "It is to be returned to the bank in an hour’s time." "I am indeed fortunate," Carne replied, and turned to the description of some curious Indian wood carving, of which he was making a special feature in his book. As he explained, he had collected his illustrations from the doors of Indian temples, from the gateways of palaces from old brass work, and even from carved chairs and boxes he had picked up in all sorts of odd corners. Her Grace was most interested. "How strange that you should have mentioned it," she said. "If carved boxes have any interest for you, it is possible my jewel case itself may be of use to you. As I think I told you during Lady Amberley’s dinner, it came from Benares, and has carved upon it the portraits of nearly every god in the Hindu Pantheon." "You raise my curiosity to fever heat," said Carne. A few moments later the servant returned, bringing with him a wooden box, about sixteen inches long, by twelve wide, and eight deep, which he placed upon a table beside his mistress, after which he retired. "This is the case to which I have just been referring," said the Duchess, placing her hand on the article in question. "If you glance at it you will see how exquisitely it is carved." Concealing his eagerness with an effort, Simon Carne drew his chair up to the table, and examined the box.
