He found himself seated at the piano, while his hostess's tiny figure was thrown forward listening to him with rapt attention. Suddenly—while her husband was laughing loud at something Mrs. Doyle had said—she put out her hand and said: "Good-bye. Come next Saturday. Now go. Go quick." And he rose and took his leave.

He described his visit to Nancy, who was so much astonished that he thought it wise to omit the reference to next Saturday. On the following morning another pile of papers lay on the desk for him, and he worked on conscientiously. On Saturday a mauve envelope containing twenty dollars was placed on the top of his papers; and on a slip of paper was written: "Come at six."

At six he went to No. 8, and found Mrs. Van Osten alone. She scarcely spoke to him until her husband came in. Then she seemed suddenly to wake up, and was all smiles and pretty gestures; when Aldo spoke to her she drooped her lashes and played with her long chiffon scarf. He left her a little later, feeling dense and bewildered.

A fortnight afterwards he was invited to dinner. "I am sure Van Osten feels that he can trust me now," said Aldo to Nancy, adjusting a faultless tie at the summit of an impeccable shirt-front. "And to-day he will probably speak to me of our work."

"I am afraid Anne-Marie is going to have measles," said Nancy, sitting drearily on the old green armchair, while Anne-Marie pulled some of the stuffing out of it with languid feverish hand. "Seventh Avenue is full of it."

"It is a beastly neighbourhood," said Aldo, buttoning his waistcoat, and fixing a sham gold chain into his watch-pocket with a safety-pin. "We must get out of it as soon as we can."

"Did those people you met at Mrs. Van Osten's ask where we lived?" asked Nancy.

"Yes. And on the spur of the moment I said Number 59 in the same street. That is where the office is, you know. I hope they won't make inquiries."

Nancy sighed. Aldo kissed her, and carefully patted Anne-Marie, who had dirty hands and a tearful face. Then he ran down and got on a car that took him up town.

No reference was made during dinner to politics or to the work. There were a dozen people present, and once—to try him, Aldo felt it!—his host said, looking straight at him: "And what are you doing in New York, Mr. Della Rocca?"
