"I don't see very well how I can do it myself," Jack responded. "But Claire knows a great many of these people, and I should think she would not have the slightest difficulty in doing what we need. Anyway, I'll go round and see her to-morrow morning, and tell her exactly what has taken place. Is it all that time? Really, I must go to bed and try and get some sleep. Good-night."

After all, youth will be served, even in the way of sleep; and Jack was surprised to find, on waking next morning, that it was nearly ten o'clock. It was nearly twelve before he knocked at the door of the house in Panton Square and asked to see Claire. It was Serena who answered the summons--Serena, gray and silent and subdued in the morning light. All the same, she gave Jack one swift, furtive glance before her eyes sought the floor again.

"I will go up to the drawing-room myself," Jack said. "So you are none the worse for your last night's adventure, Serena? Come, you need not look at me like that, and pretend not to understand. What were you doing in Mr. Carrington's flat last night?"

A sound like a sob broke from Serena, but she answered nothing. "If you only knew how profoundly sorry I am for you," Jack said softly. "When the time comes, you will have to speak; and when the time comes we shall deal with you as kindly as possible. Although you refuse to speak now, you must not believe otherwise than that. We know everything. We know, for instance, where you were last night, and we have nothing to learn as to the deaf mute and the young man who has a fancy to wear his moustache in the same form as the style affected by the German Emperor."

Serena listened, with her eyes fixed mutely on Jack's face. It seemed to him that she was bursting with anxiety to speak, but that some strange force held her tongue and choked her utterance.

"Do not go too far," she said presently, in a strained, hard whisper. "Not that I mean to threaten you. Believe me, I am all on your side; but I dare not speak. You may call me coward if you like; you may say that I have no nerve or courage; but if you had gone through the hell that my life has been the last few years, you would wonder that I had the strength of mind to look even the feeblest fellow creature in the face."

Just at the moment when it seemed to Jack that Serena was likely to take him into her confidence, she turned abruptly away, and disappeared in the direction of the kitchen. Jack went slowly and thoughtfully up-stairs to the drawing-room, where he found Claire with her hat on ready to go out. It was clear that she had not expected him, but her welcome was none the less warm for that.

"I am afraid I shall have to detain you a little time, dearest," Jack said. "A great deal has happened since I saw you yesterday, and I think you ought to know most of it. Sit down a moment, please." Claire sat by her lover's side, and listened intently to the strange story that he had to tell. It was clear from the expression of her blue eyes that she was a little fearful for her lover. She clutched his arm impulsively, and he responded to the touch. It was not difficult for him to realize what was passing in her mind.

"You need not have any anxiety as far as I am concerned," he said. "Very fortunately for us, those scoundrels have not the least idea that we know so much of their movements. But what I came here especially for this morning was to ask you if you knew anybody going to Lady Barmouth's dance whose jewels are in the keeping of Carrington's bank? I think I explained Rigby's point to you. Do you know anybody who could help us?"

"I know one who could help you who is not very far off, dear old boy," Claire smiled. "You seem to have forgotten that I am rather an important person in my small way. Did I never tell you of the jewels that my grandmother left me?"
