"Signor Baroni?"

"Have you an appointment?" came the relentless inquiry, and Diana could well imagine how inexorably the greatly daring who had come on chance would be turned away.

"Yes—oh, yes," she stammered. "For three o'clock—Miss Diana Quentin."

"Come this way, please." The man stood aside for her to enter, and a minute later she found herself following him through a narrow hall to the door of a room whence issued the sound of a softly-played pianoforte accompaniment.

The sphinx-like one threw open the door and announced her name, and with quaking knees she entered.

The room was a large one. At its further end stood a grand piano, so placed that whoever was playing commanded a full view of the remainder of the room, and at this moment the piano-stool was occupied by Signor Baroni himself, evidently in the midst of giving a lesson to a young man who was standing at his elbow. He was by no means typically Italian in appearance; indeed, his big frame and finely-shaped head with its massive, Beethoven brow reminded one forcibly of the fact that his mother had been of German origin. But the heavy-lidded, prominent eyes, neither brown nor hazel but a mixture of the two, and the sallow skin and long, mobile lips—these were unmistakably Italian. The nose was slightly Jewish in its dominating quality, and the hair that was tossed back over his head and descended to the edge of his collar with true musicianly luxuriance was grizzled by sixty years of strenuous life. It would seem that God had taken an Italian, a German, and a Jew, and out of them welded a surpassing genius.

Baroni nodded casually towards Diana, and, still continuing to play with one hand, gestured towards an easy-chair with the other.

"How do you do? Will you sit down, please," he said, speaking with a strong, foreign accent, and then apparently forgot all about her.

"Now"—he turned to the young man whose lesson her entry had interrupted—"we will haf this through once more. Bee-gin, please: 'In all humility I worship thee.'"

Obediently the young man opened his mouth, and in a magnificent baritone voice declaimed that reverently, and from a great way off, he ventured to worship at his beloved's shrine, while Diana listened spell-bound.
