"Why I am here to-night I cannot even tell you," Lady Barmouth said, in low, nervous tones. "The secret is not mine; it concerns one I love more than anybody else in the world. One thing I can tell you: Claire Helmsley is in great danger so long as she remains where she is living now. You must get her away, Mr. Masefield; you must get her away at any cost."

Jack nodded gravely; he had not been blind to this danger for some time. What he wanted to know now was if Lady Barmouth had any idea of the identity of the man who had successfully got the better of Redgrave. But on that head Lady Barmouth could say nothing; she had returned for the express purpose of relieving Masefield and Rigby from their awkward situation, and in so doing she had come quite unexpectedly upon the combatants. Even in the dim light she had seen that a murderous struggle was taking place, and this being so, had hastened headlong up-stairs with a view to securing assistance. More than this she could not possibly say.

"What we want to do," Rigby suggested, "is to go away quietly somewhere, and discuss this matter thoroughly. I need not point out to your ladyship the manifest danger of staying here. Anstruther or any of his tribe may be back at any time, and then we shall be caught like rats in a trap."

"That matter is easily settled," Lady Barmouth replied. "Could you come home with me? It is by no means late yet, and you would not be long in getting rid of those disguises of yours. They are excellent disguises, but they did not prevent me recognizing you, Mr. Masefield."

"There is no deceiving a clever woman," Jack smiled. "I should like nothing better than a chance to discuss this matter at length--but Lord Barmouth? Would he not think it somewhat singular that two strangers like ourselves----"

"Nothing of the sort!" Lady Barmouth cried eagerly. "My husband never goes outside the house; he is suffering from a trouble so terrible that I try not to think of it if I can. I may, however, tell you that his trouble is intimately connected with the black business that brings us here to-night. It may seem to you that I am a mere frivolous society butterfly. Ah, if you only knew!"

The trio had worked their way into the street by this time. A private hansom stood a little way down the road. Lady Barmouth smiled a little as she contemplated her two companions.

"I am afraid we should be a suspicious-looking party in the eye of a passing policeman," she said . "No, I think it would be just as well if I walked to my hansom alone. Then you can go back to your rooms and attire yourselves as English gentlemen should be attired at this time of the evening. Then you can come to my house; I will tell the servants I am expecting two friends to supper. You know the address."

Jack intimated that he knew the address perfectly well. The suggestion was by no means a bad one; there could be no possible suspicion aroused by the fact that Lady Barmouth was having two friends to share her late meal. The clocks were striking twelve as Jack and his companion walked up the steps of the big house in Belgrave Square.
