"It was a month ago," she reminded him.

"I can't do that sort of thing every day," he declared.

"Naturally," she answered; "but you have refused four cases within the last five days."

Peter Ruff whistled softly to himself for several moments.

"Seen anything of our new neighbour in the flat above?" he asked, with apparent irrelevance.

Miss Brown looked across at him with upraised eyebrows.

"I have been in the lift with him twice," she answered.

"Fancy his appearance?" Ruff asked, casually.

"Not in the least!" Violet answered. "I thought him a vulgar, offensive person!"

Peter Ruff chuckled. He seemed immensely delighted.

"Mr. Vincent Cawdor he calls himself, I believe," he remarked.

"I have no idea," Miss Brown declared. The subject did not appeal to her.

"His name is on a small copper plate just over the letter-box," Ruff said. "Rather neat idea, by the bye. He calls himself a commission agent, I believe."

Violet was suddenly interested. She realized, after all, that Mr.

Vincent Cawdor might be a person of some importance.

"What is a commission agent?" she asked.

Peter Ruff shook his head.

"It might mean anything," he declared. "Never trust any one who is not a little more explicit as to his profession. I am afraid that this Mr.

Vincent Cawdor, for instance, is a bad lot."

"I am sure he is," Miss Brown declared.

"Looks after a pretty girl, coughs in the lift--all that sort of thing, eh?" Peter Ruff asked.

She nodded.

"Disgusting!" she exclaimed, with emphasis.

Peter Ruff sighed, and glanced at the clock. The existence of Mr.

Vincent Cawdor seemed to pa.s.s out of his mind.

"It is nearly one o'clock," he said. "Where do you usually lunch, Violet?"

"It depends upon my appet.i.te," she answered, carelessly. "Most often at an A B C."

"To-day," Peter Ruff said, "you will be extravagant--at my expense."

"I had a poor breakfast," Miss Brown remarked, complacently.

"You will leave at once," Peter Ruff said, "and you will go to the French Cafe at the Milan. Get a table facing the courtyard, and towards the hotel side of the room. Keep your eyes open and tell me exactly what you see."

She looked at him with parted lips. Her eyes were full of eager questioning.

"Mere skirmishing," Peter Ruff continued, "but I think--yes, I think that it may lead to something."

"Whom am I to watch?" she asked.

"Any one who looks interesting," Peter Ruff answered. "For instance, if this person Vincent Cawdor should be about."

"He would recognize me!" she declared.

Peter Ruff shrugged his shoulders.

"One must hold the candle," he remarked.

"I decline to flirt with him," she declared. "Nothing would induce me to be pleasant to such an odious creature."

"He will be too busy to attempt anything of the sort. Of course he may not be there. It may be the merest fancy on my part. At any rate, you may rely upon it that he will not make any overtures in a public place like the Milan. Mr. Vincent Cawdor may be a curious sort of person, but I do not fancy that he is a fool!"

"Very well," Miss Brown said, "I will go."

"Be back soon after three," Peter Ruff said. "I am going up to my room to do my exercises."

"And afterwards?" she asked.

"I shall have my lunch sent in," he answered. "Don't hurry back, though.

I shall not expect you till a quarter past three."

It was a few minutes past that time when Miss Brown returned. Peter Ruff was sitting at his desk, looking as though he had never moved. He was absorbed by a book of patterns sent in by his new tailor, and he only glanced up when she entered the room.

"Violet," he said, earnestly, "come in and sit down. I want to consult you. There is a new material here--a sort of mouse-coloured cheviot. I wonder whether it would suit me?"

Violet was looking very handsome and a little flushed. She raised her veil and came over to his side.

"Put that stupid book away, Peter," she said. "I want to tell you about the Milan."

He leaned back in his chair.

"Ah!" he said. "I had forgotten! Was Mr. Vincent Cawdor there?"

"Yes!" she answered, still a little breathless. "There was some one else there, too, in whom you are still more interested."

He nodded.
