“That’s the question. It is suspected that he met her in the hunting-field, persuaded her to meet him secretly, and finally won her to fly from home. To me this is quite credible; for I’ve seen Johann Strauss twice, and each time have been struck with the thought how fascinating this man must be in the eyes of a young woman!”

“What was he like, then, this Mr. Johann Strauss of the flourishy signature?”

“A most handsome young man,” said Mr. Dibbin, impressively; “hard to describe exactly. Came from the States, I think, or had lived there—had just a touch of the talk, perhaps—of Dutch extraction, I take it. Handsome fellow, handsome fellow; the kind of man girls throw themselves over precipices after: teeth flashing between the wings of his black mustache—tall, thin man, always most elegantly dressed—dark skin—sallow—”

At that word “sallow,” David started, the description of Johann Strauss had so strangely reminded him of Van Hupfeldt! But the thought that the cause of the one sister’s undoing should be friendly with the other sister, paying his court to her over the grave of the ill-fated dead, was too wild to find for itself a place all at once in the mind.

David frowned down the notion of such a horror. He told himself that it was dark when he had seen Van Hupfeldt, that there were many tall men with white teeth and black mustaches, and sallow, dark skins. If he had felt some sort of antipathy to Van Hupfeldt at first sight, this was no proof of evil in Van Hupfeldt’s nature, but a proof only, perhaps, of David’s capabilities of being jealous of one more favored than himself by nature as he fancied—and by Violet Mordaunt, which was the notion that rankled.

And yet he tingled. Dibbin had said that this Van Hupfeldt might be “a new friend—one who had become a friend since the death of Gwendoline.”

David paced the room with slow steps, and while Dibbin talked on of one or another of the people who had known Gwendoline Mordaunt in the flesh, vowed to himself that he would take this matter on his shoulders and see it through.

“Speaking of the Miss L’Estrange who was in the flat before me,” said he; “how long did she stay in it?”

“Three months, nearly,” answered Dibbin, “and then all of a sudden she wouldn’t stay another day. And I had no means of forcing her to do so either.”

“What? Did the ghost suddenly get worse?”
