"No." Joan Carew reflected for a moment with her eyes upon the carpet, and then flung up her head with a gesture of despair. "No. I try all the time to remember. But it is no good."

Mr. Ricardo could not restrain a movement of indignation. He was being played with. The girl with her fantastic story had worked him up to a real pitch of excitement only to make a fool of him. All his earlier suspicions flowed back into his mind. What if, after all, she was implicated in the murder and the theft? What if, with a perverse cunning, she had told Hanaud and himself just enough of what she knew, just enough of the truth, to persuade them to protect her? What if her frank confession of her own overpowering impulse to steal the necklace was nothing more than a subtle appeal to the sentimental pity of men, an appeal based upon a wider knowledge of men's weaknesses than a girl of nineteen or twenty ought to have? Mr. Ricardo cleared his throat and sat forward in his chair. He was girding himself for a singularly searching interrogatory when Hanaud asked the most irrelevant of questions:

"How did you pa.s.s the evening of that night when you first dreamed complete the face of your a.s.sailant?"

Joan Carew reflected. Then her face cleared.

"I know," she exclaimed. "I was at the opera."

"And what was being given?"

"_The Jewels of the Madonna_."

Hanaud nodded his head. To Ricardo it seemed that he had expected precisely that answer.

"Now," he continued, "you are sure that you have seen this man?"

"Yes."

"Very well," said Hanaud. "There is a game you play at children's parties--is there not?--animal, vegetable, or mineral, and always you get the answer. Let us play that game for a few minutes, you and I."

Joan Carew drew up her chair to the table and sat with her chin propped upon her hands and her eyes fixed on Hanaud's face. As he put each question she pondered on it and answered. If she answered doubtfully he pressed it.

"You crossed on the _Lucania_ from New York?"

"Yes."

"Picture to yourself the dining-room, the tables. You have the picture quite clear?"

"Yes."

"Was it at breakfast that you saw him?"

"No."

"At luncheon?"

"No."

"At dinner?"

She paused for a moment, summoning before her eyes the travellers at the tables.

"No."

"Not in the dining-table at all, then?"

"No."

"In the library, when you were writing letters, did you not one day lift your head and see him?"

"No."

"On the promenade deck? Did he pa.s.s you when you sat in your deck-chair, or did you pa.s.s him when he sat in his chair?"

"No."

Step by step Hanaud took her back to New York to her hotel, to journeys in the train. Then he carried her to Milan where she had studied. It was extraordinary to Ricardo to realise how much Hanaud knew of the curriculum of a student aspiring to grand opera. From Milan he brought her again to New York, and at the last, with a start of joy, she cried: "Yes, it was there."

Hanaud took his handkerchief from his pocket and wiped his forehead.

"Ouf!" he grunted. "To concentrate the mind on a day like this, it makes one hot, I can tell you. Now, Miss Carew, let us hear."

It was at a concert at the house of a Mrs. Starlingshield in Fifth Avenue and in the afternoon. Joan Carew sang. She was a stranger to New York and very nervous. She saw nothing but a mist of faces whilst she sang, but when she had finished the mist cleared, and as she left the improvised stage she saw the man. He was standing against the wall in a line of men. There was no particular reason why her eyes should single him out, except that he was paying no attention to her singing, and, indeed, she forgot him altogether afterwards.

"I just happened to see him clearly and distinctly," she said. "He was tall, clean-shaven, rather dark, not particularly young--thirty-five or so, I should say--a man with a heavy face and beginning to grow stout. He moved away whilst I was bowing to the audience, and I noticed him afterwards walking about, talking to people."

"Do you remember to whom?"

"No."

"Did he notice you, do you think?"

"I am sure he didn't," the girl replied emphatically. "He never looked at the stage where I was singing, and he never looked towards me afterwards."

She gave, so far as she could remember, the names of such guests and singers as she knew at that party. "And that is all," she said.

"Thank you," said Hanaud. "It is perhaps a good deal. But it is perhaps nothing at all."

"You will let me hear from you?" she cried, as she rose to her feet.

"Miss Carew, I am at your service," he returned. She gave him her hand timidly and he took it cordially. For Mr. Ricardo she had merely a bow, a bow which recognised that he distrusted her and that she had no right to be offended. Then she went, and Hanaud smiled across the table at Ricardo.

"Yes," he said, "all that you are thinking is true enough. A man who slips out of society to indulge a pa.s.sion for a drug in greater peace, a girl who, on her own confession, tried to steal, and, to crown all, this fantastic story. It is natural to disbelieve every word of it.

But we disbelieved before, when we left Calladine's lodging in the Adelphi, and we were wrong. Let us be warned."

"You have an idea?" exclaimed Ricardo.

"Perhaps!" said Hanaud. And he looked down the theatre column of the _Times_. "Let us distract ourselves by going to the theatre."

"You are the most irritating man!" Mr. Ricardo broke out impulsively.

"If I had to paint your portrait, I should paint you with your finger against the side of your nose, saying mysteriously: '_I_ know,' when you know nothing at all."

Hanaud made a schoolboy's grimace. "We will go and sit in your box at the opera to-night," he said, "and you shall explain to me all through the beautiful music the theory of the tonic sol-fa."

They reached Covent Garden before the curtain rose. Mr. Ricardo's box was on the lowest tier and next to the omnibus box.

"We are near the stage," said Hanaud, as he took his seat in the corner and so arranged the curtain that he could see and yet was hidden from view. "I like that."
