"I have not said so. I am only seeking information abort the lady--Maud Petrovitch, I think you said was her name?"

"Whatever I can tell you is only in her favour. She was a dear--a very dear friend of mine."

"Ah! then you have quarrelled--eh?" he said, looking at her sharply.

"You said she was your friend--you used the past tense."

"I know."

"Why?"

"Because,"--and she grew confused--"well, because something has happened."

"To interrupt pure friendship?"

She did not reply. He had craftily led up the conversation to Maud, and was, as he had openly told her, seeking information. He watched the flush upon her cheeks, and the nervous manner in which she picked at her skirt.

"And yet, though you are friends no longer, you are in favour of your brother's marriage with the lady? That appears strange. I suppose he loves her. Every man loves at his age, and lives to regret it at forty," he added with that touch of biting sarcasm that was never absolutely absent from his remarks.

"Yes; Charlie does love her. I'm convinced of that. And her devotion to him has always been very marked, from the first time they were introduced at Aix-les-Bains. She has told me how deep is her affection for him."

"At Aix-les-Bains," Statham exclaimed in surprise: "I thought Doctor Petrovitch lived in London?"

"And so he did--until recently."

"Where is he now? I would much like to meet him again."

"I do not know. He left London suddenly with his daughter."

"Your brother would know, of course."

"No. He also is unaware of their present whereabouts," she answered quickly, adding: "Recollect your promise not to mention the matter to him."

"When I make a promise, Miss Rolfe, I keep it," was his grave response.

"Only forgive me for saying so, but you appear to be a little evasive regarding the Doctor's daughter."

"Evasive?" she echoed. "I don't understand you, Mr Statham."

"Well, you are trying to mislead me," he answered, knitting his brows and looking her straight in the face. "And let me say that when you try to mislead Sam Statham you have a difficult task."

She started at his sudden change of manner, and again became confused.

"Now," he said, bending forward to her from his chair, "let us understand each other at the outset. You were the most intimate friend of this girl Maud who, with her father, suddenly disappeared from London. The facts of their disappearance are already known to me, I may as well tell you that much. They vanished, and took their household goods with them. Perhaps they were afraid of anarchists or political enemies, or perhaps the Doctor is wanted by the police. Who knows? It was a mystery, and as such remains, is not that so?"

She nodded. This knowledge of his astounded her. She had believed that the disappearance was only known to the two or three persons who had been the Petrovitchs' personal friends. She little dreamed of the many spies in the pay of the great financier, men and women who reported to him any political move at home or abroad which might influence the markets. The world had often believed that Sam Statham was omnipresent.

They knew nothing of his agents, or of their secret visits.

"Now, Miss Rolfe, let us advance one step further," the old man said, still keeping his keen gaze upon hers. "If you will kindly carry your mind back to the day of their disappearance, you will remember that you accompanied the Doctor's daughter to a concert at Queen's Hall."

"How do you know that?" she cried, starting up from her chair.

"How I know it is immaterial," he said firmly. "Kindly re-seat yourself."

"I will not," she declared boldly. "You are cross-examining me as though I were a criminal. This is outrageous!"

"I politely request you to sit down, Miss Rolfe," he said, never moving a muscle.

Her beautiful face was flushed with resentment and anger, as, standing erect before him, she faced him in open defiance.

"I see no further point in this interview," was her cool reply. "I will go."

"I think it would be wiser for you to remain," he responded in a low, determined voice; "wiser for you to answer my questions."

"I have already answered them."

"I wish to know something further," he said, stirring again in his chair, and waving his hand with a repeated request that she would be re-seated.

"I have nothing to conceal," was her reply, attempting to smile. "Why should I?"

"Why, indeed," he said, "I may as well tell you that I have reasons-- very strong business reasons--for elucidating this mystery concerning Doctor Petrovitch. To me it involves a question of many thousands of pounds. I have considerable interests out in Servia, as your brother may have explained to you. I must find the Doctor, and the reason I have asked you here to-night is to invoke your aid in a.s.sisting me to do so. Can I be more explicit?"

He looked in her face, but a shrewd observer would have known by the wavering smile at the corners of his mouth that he was not speaking the exact truth. There was some trick or motive underlying it all.

Though she did not detect this, she was still undecided. Anger was aroused within her by his commanding manner. His att.i.tude had changed so suddenly that she had been taken thoroughly aback.

"I am afraid, Mr Statham, that I cannot render you any a.s.sistance in discovering the whereabouts of the Petrovitchs."

"But, my dear young lady!" he cried. "They had servants. Surely there is one who could give us some very valuable information."

"Perhaps so, if he or she could be found," she remarked. "They, no doubt, took every precaution against being followed. As a matter of fact, so great a care has the Doctor taken that his most intimate friend in London is in ignorance."

"And who is he, pray?" asked the millionaire quickly.

"A gentleman named Barclay--Mr Max Barclay."

"Max Barclay! I've heard of him. A friend of your brother's, eh? And so he was the Doctor's friend?"

"They were inseparable, but the Doctor left without a word of farewell."

"And also the daughter--except to you, Miss Rolfe," he said, looking at her meaningly.

"To me?"

"Yes," he went on, his keen gaze again upon her. "It is useless to a.s.sume ignorance. You know quite well that the doctor's daughter, on the night of their disappearance, made a statement to you--an important statement."

"My brother told you that!" she cried. "He has told you everything!"

"He has told me nothing," replied the old man coldly. "I only ask whether you deny that she made a statement."
