Before she could mention her London address they were both aware that a third person was with them. The light carpet of snow would not have deadened the newcomer's approach to David's ears, were it not that he was so absorbed in the words, the looks, the merest gestures of his companion. David heard the girl say; "Oh, Mr. Van Hupfeldt!" and a man walked past him to the grave with lifted hat. The man and Violet Mordaunt shook hands. It was now getting dark; but David could still see that the newcomer was an uncommonly handsome person, turned out with faultless elegance from his glossy beaver to the tip of his _verni_ boots; of dark, sallow skin; and a black mustache as daintily curled as those mustaches which one sees in the costumers' windows. David stepped back a little, and stood awkwardly. Beside this West End dandy he felt that he was somewhat of a rough-rider, and, like most young men dowered with both brain and sinew, he fancied that women incline more readily to the trimly dressed popinjay of society. Yet Violet Mordaunt seemed anything but pleased at the interruption. "I am come to look for you by the request of your mother," David heard the stranger say. "It was feared that you might be here, and I am to take you home, if you will do me the honor to come in my carriage." "But I ought not to be tracked," said Violet, with the quick petulance which already was music for David. "There is the question of tea and dinner," remarked Van Hupfeldt. "If a lady will not eat, she must expect to be plagued." "I prefer to walk home." "That couldn't be done; it is too far," said Van Hupfeldt. "Oh, come, come!" he went on pleadingly, with a fond gaze into her eyes. A minute afterward they left the grave together. Van Hupfeldt, as he passed David on the path, frowned momentarily; Violet slightly inclined her head. He looked after them, and admitted to himself that they made a handsome pair, tall, like children of the gods. But three yards away after they had passed him something fell from Violet--a card--whether by accident or design David did not know; but the thought that it might be by design sent a thrill through his frame. He picked it up. It had on it the address of a boarding-house in Porchester Gardens. He was yet tingling with the hope of meeting her again when a custodian approached. "Must shut the gates, sir," he said. And the clang of iron brought David back to the roadway and reality once more. CHAPTER IV "JOHANN STRAUSS" On Monday morning David made the acquaintance of the _genus_ "housekeeper," when the woman recommended by Dibbin arrived to take him in hand. He had thought that she would sleep in the place, and had rather looked forward to the human companionship, for nothing is more cut off from the world of the living than a flat, if one is alone in it, especially through the watches of the night. Surely, if there are ghosts in want of undisturbed house-room, every bachelor's flat must be haunted.
