Followed the tense instant that always precedes the performance of an orchestra, then Phyllis and Robin began the world-known sextette from “Lucia.” Robin had sung it so many times in private to the accompaniment of her cousin’s violin that the attack was perfect. The others took it up immediately, filling the night with echoing sweetness.

From their position at the next window the watchers saw the dark, solemn face of the Italian raised in bewildered amazement from his paper. Not quite comprehending at first the unbidden flood of music which met his ears, he listened for a moment in patent stupefaction. Soon a smile began to play about his tight little mouth. It widened into a grin of positive pleasure. Giuseppe understood that a great honor was being done him. He was not only being serenaded, but he was listening to the music of his native country as well.

His varying facial expressions, as the sextette rose and fell, showed his love of the selection. As it ended, he did an odd thing. He rose from his chair, bowed his profound thanks toward the window from whence came the singing, and sat down again, looking expectant.

“He knows very well he’s being watched,” whispered Marjorie. “Doesn’t he look pleased? I’m so glad you thought of him, Lucy.”

Lucy was also showing shy satisfaction at the success of her proposal. She was secretly more proud of some small triumph of the kind on her part than of her brilliancy as a student.

Had Signor Baretti been attending a performance of grand opera, he could not have shown a more evident pleasure in the programme. He listened to the entertainment so unexpectedly provided him with the rapt air of a true music-lover.

“There!” softly exclaimed Phyllis, as she lowered her violin. “That’s the end of the programme, Signor Baretti. Now for that fresh peach ice cream. I shall have coffee and mountain cake with it. I am as hungry as the average wandering minstrel.”

“Let’s walk in as calmly as though we had never thought of serenading Giuseppe,” said Robin. “Oh, we can’t. I forgot. The orchestra part of this aggregation is a dead give-away.”

“We don’t care. He will know it was we who were out there. There is no one else about but us. I hope he won’t think we are a set of little Tommy Tuckers singing for our suppers. That’s a horrible afterthought on my part,” Elaine laughed.

“Come on.” Jerry and her group had now joined the singers. “He saw us but not until you were singing that Nevin selection. He kept staring at the window where the sound came from. We had our faces right close to our window and all of a sudden he looked straight at us. You should have seen him laugh. His whole face broke into funny little smiles.”
