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 consolatory observations, 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.
