He rapped and the door was opened by the step-son in black. He at once called Mrs. Cave, who was, Mr. Wace could not but observe, in cheap but ample widow's weeds of the most imposing pattern. Without any very great surprise Mr. Wace learnt that Cave was dead and already buried. She was in tears, and her voice was a little thick. She had just returned from Highgate. Her mind seemed occupied with her own prospects and the honourable details of the obsequies, but Mr. Wace was at last able to learn the particulars of Cave's death. He had been found dead in his shop in the early morning, the day after his last visit to Mr. Wace, and the crystal had been clasped in his stone-cold hands. His face was smiling, said Mrs. Cave, and the velvet cloth from the minerals lay on the floor at his feet. He must have been dead five or six hours when he was found. This came as a great shock to Wace, and he began to reproach himself bitterly for having neglected the plain symptoms of the old man's ill-health. But his chief thought was of the crystal. He approached that topic in a gingerly manner, because he knew Mrs. Cave's peculiarities. He was dumfounded to learn that it was sold. Mrs. Cave's first impulse, directly Cave's body had been taken upstairs, had been to write to the mad clergyman who had offered five pounds for the crystal, informing him of its recovery; but after a violent hunt, in which her daughter joined her, they were convinced of the loss of his address. As they were without the means required to mourn and bury Cave in the elaborate style the dignity of an old Seven Dials inhabitant demands, they had appealed to a friendly fellow-tradesman in Great Portland Street. He had very kindly taken over a portion of the stock at a valuation. The valuation was his own, and the crystal egg was included in one of the lots. Mr. Wace, after a few suitable condolences, a little off-handedly proffered perhaps, hurried at once to Great Portland Street. But there he learned that the crystal egg had already been sold to a tall, dark man in grey. And there the material facts in this curious, and to me at least very suggestive, story come abruptly to an end. The Great Portland Street dealer did not know who the tall dark man in grey was, nor had he observed him with sufficient attention to describe him minutely. He did not even know which way this person had gone after leaving the shop. For a time Mr. Wace remained in the shop, trying the dealer's patience with hopeless questions, venting his own exasperation. And at last, realising abruptly that the whole thing had passed out of his hands, had vanished like a vision of the night, he returned to his own rooms, a little astonished to find the notes he had made still tangible and visible upon, his untidy table.
