"Yes, I am aware of that," Vera said. "I could never make it out—I could never really believe that Charles Evors was guilty of that dreadful crime. He was so frank and true, so kind to everybody! I know he was weak—I know that he had been sent away from England because he had fallen into bad company; I know, too, that he was a little fond of drink. There was only one point on which he was reticent—he never spoke much about his people; but I rather gathered that they were in a high position."

"They were," Fenwick grinned. "You'd be surprised if you knew how high a position. But go on."

"I was saying that I could not credit Charles Evors with such a crime. A man who is so fond of children, so sympathetic to things weaker than himself, could not have taken the life of a fellow-creature. He was fond of my father, too, but that was not the strangest feature of the mystery. Do you suppose for a moment that the man who was engaged to be married to my sister could have laid violent hands on her father?"

"But he did do it," Fenwick cried impatiently. "Otherwise why did he vanish so mysteriously? Why did he go away and leave us to infer that he had perished at sea? It was the kindest thing we could do to let your sister think that her lover was dead, though the shock seems to have deprived her of her reason; and, though I acted all for the best, your brother chose to proclaim me an abandoned scoundrel, and to say that your father's death lay at my door. You know why it became necessary for you to remain with me and treat your brother henceforth as a stranger. You volunteered to do it, you volunteered to turn your back on your family and remain with me. Why did you do so?"

No reply came from Vera's lips. It seemed to her that her safest course lay in silence. To her great relief, Fenwick went on without waiting for an answer.

"Now I am coming to my point," he said. "You have broken faith with me. Three or four times since we came to England you have seen your brother. You have seen him by stealth; you know all about that strange household in Portsmouth Square where he chooses to hide himself under the name of Bates. I want to know why it is that you have chosen to break your word with me? I have had you watched to-night, and I have learned all your movements by means of the telephone. You will stay down here during my pleasure. If you fail to do so, or if you try to deceive me again, as sure as I stand here at the present moment I will betray Charles Evors into the hands of the police. Now look me in the face and answer my question truthfully Do you know where that young man is?"

It was fortunate for Vera that she could reply in the negative. A few more hours, perhaps, and she might have been able to afford the information; but, luckily for her, the startling events that had recently taken place in Portsmouth Square were not known to her in their entirety. She could look Fenwick in the face.

"I don't," she said. "I have never seen him since that fateful morning—but I don't care to go into that. I admit that I have seen my brother. I admit, too, that I have seen my sister; the temptation to find them and see them once more was too strong for me. You will not be surprised to find that I have some natural feelings left. It is not so very extraordinary."

Fenwick shot a suspicious glance at Vera, but she was gazing into the fire with a thoughtful look. She was acting her part splendidly; she was deceiving this man who, as a rule, could read the thoughts of most people.

"Perhaps you are right," he said doubtfully. "But to make assurance doubly sure you are going to help me out of a difficulty. I suppose you have not forgotten Felix Zary?"
