"Serena," she said gently. "Serena, I want you."
There was a violent agitation, that shook the listener's frame; but she rose very gently, and passed along the corridor by Claire's side without the slightest protest. They came to a little alcove at length, and Claire bade her companion sit down.
"I know why you are here to-night," she explained. "I even know what your appointed task is. But, what is still more important, I am acquainted with the hold that Anstruther has upon you. Believe me, you have no firmer friend in the world than myself. Tell me your sad story, and let me see if I can help you."
The gently spoken words were not without their effect. Heedless of consequences, Serena removed her mask, and proceeded to wipe the streaming tears from her eyes.
"I will tell you everything," she murmured. "You know already that Lady Barmouth is my sister, and you are acquainted with the fact that Padini is my husband; but nobody knows besides Anstruther that I was once the mother of a little boy. I was always wilful and headstrong. I was always ready to throw away my happiness for the whim of the moment. That is why I married Padini, who basely deserted me when he found that I had no money. A month after our marriage I was alone in the world, almost starving. I was too proud to send to my friends; I had meant to wait till my money was exhausted, and then throw myself into the river. But I dared not do that, because of the fresh young life which I knew was coming to me. I managed to make a little money, and when my child was born I was comparatively happy. When the boy was about eighteen months old, Anstruther found me out, and professed a desire to become my friend. It was about that time that Padini turned up again, and began to blackmail me. I cannot tell you exactly what happened; they say I tried to kill him because he would have taken my child from me. At any rate, I have always been informed that I might have suffered a long term of imprisonment if Anstruther had not stood my friend."
"But this does not give him so great a power over you," Claire said. "A mere act of charity like that----"
"But I have not told you everything," Serena whispered. "For a short time I was a mad woman. And when I came to myself again, they told me that I had killed my boy. Oh, I have no wish to dwell upon that dreadful time--I hardly dare to think of it without a wild desire to lay hands upon myself. And yet there are times when I believe the whole thing to have been a wicked lie, a pure invention on the part of Anstruther. At these times I believe that my boy is still safe and sound, and that some day we shall meet again. This is the whole secret of the reason why I have clung to Anstruther, and why I have been the slave of his base designs. But this story must be told to no one, not even to Lady Barmouth."
Serena might have said more, only the sound of approaching footsteps warned Claire of the necessity for caution. She whispered to Serena to replace her mask--a precaution that was none too soon, for Anstruther was impatiently coming down the corridor side by side with another man, whom Claire recognized as Lord Barmouth.
"I have been looking for you everywhere," Anstruther said. "What do you mean by hiding yourself here?
"It was quite clear that Anstruther had lost his head for the moment. Lord Barmouth paused, and looked at the other sternly and coldly. Yet he hesitated, as if half afraid to speak. He had the advantage over Anstruther in knowing who the latter was, while still preserving the secret of his own identity.
