It was with justice she had described it as a work of art. What the wood was of which it was constructed Carne was unable to tell. It was dark and heavy, and, though it was not teak, it closely resembled it. It was literally covered with quaint carving, and of its kind was an unique work of art. "It is most curious and beautiful," said Carne when he had finished his examination. "In all my experience I can safely say I have never seen its equal. If you will permit me I should very much like to include a description and an illustration of it in my book." "Of course you may do so; I shall be only too delighted," answered Her Grace. "If it will help you in your work I shall be glad to lend it to you for a few hours, in order that you may have the illustration made." This was exactly what Carne had been waiting for, and accepted the offer with alacrity. "Very well, then," she said. "On the day of my ball, when it will be brought from the bank again, I will take the necklace out and send the case to you. I must make one proviso, however, and that is that you let me have it back the same day." "I will certainly promise to do that," replied Carne. "And now let us look inside," said his hostess. Choosing a key from a bunch carried in her pocket, she unlocked the casket, and lifted the lid. Accustomed as Carne had all his life been to the sight of gems, what he then saw before him almost took his breath away. The inside of the box, both sides and bottom, was quilted with the softest Russia leather, and on this luxurious couch reposed the famous necklace. The fire of the stones when the light caught them was sufficient to dazzle the eyes, so fierce was it. As Carne could see, every gem was perfect of its kind, and there were no fewer than three hundred of them. The setting was a fine example of the jeweller’s art, and last, but not least, the value of the whole affair was fifty thousand pounds, a mere flea-bite to the man who had given it to his wife, but a fortune to any humbler person. "And now that you have seen my property, what do you think of it?" asked the Duchess as she watched her visitor’s face. "It is very beautiful," he answered, "and I do not wonder that you are proud of it. Yes, the diamonds are very fine, but I think it is their abiding-place that fascinates me more. Have you any objection to my measuring it?" "Pray do so, if it’s likely to be of any assistance to you," replied Her Grace. Carne thereupon produced a small ivory rule, ran it over the box, and the figures he thus obtained he jotted down in his pocket-book. Ten minutes later, when the case had been returned to the safe, he thanked the Duchess for her kindness and took his departure, promising to call in person for the empty case on the morning of the ball.
