"Now tell me candidly," Lady Barmouth said at length, "have you any ideas to offer as to that mysterious disappearance from Shannon Street police station? I am asking you this, Mr. Masefield, because it was you who actually found the body of the man who most people speak of as Nostalgo. Really, now, was that unfortunate man so very like the wonderful poster of which London has had to say so much of late?"

"The likeness was amazing," Jack explained. "It quite frightened me. Talking about the poster in question, there is another likeness that I have not failed to note. Of course, if you put the man I mean and the poster side by side, nobody could possibly see the resemblance. But in moments of anger, there is a strong likeness between the poster and Spencer Anstruther. Don't laugh at me, Lady Barmouth; I assure you it is absolutely true."

But Lady Barmouth was by no means in the way of laughing at Masefield. Her pale face took on a still more creamy pallor, the pupils of her dark eyes were strangely dilated. "That is a most strange and wonderful thing," she said , as if speaking to herself. "Mr. Masefield, it is most fortunate that we met to-night. You have just told me something which will prove of the utmost value later on. We will not discuss that now, there is no time. But there is one thing that I am going to ask you to do for me; I want you to influence Claire Helmsley in my favor. I have taken a great fancy to her; indeed, I like her far more than any girl in London. This is all the stranger because I believe I am in a position to do her a great service. I know that I am in a position to do her one. But one stipulation I make, and that is--she must be told everything."

Jack hesitated. It would be indeed a dangerous thing to acquaint Claire with all that had happened so long as she was under the same roof as Spencer Anstruther. She was not accustomed to restrain her feelings and emotions, and with his swift, subtle instincts, Anstruther would find out that there was something wrong immediately. Jack pointed this out to Lady Barmouth at some length.

"I don't think so," she said thoughtfully. "Claire is a clever girl, she is in splendid health, and not the least likely to fear Anstruther or anybody else. It is, of course, not nice to have to play a part, but think of the information that Claire could glean for us so long as Anstruther regards her as little more than a child and behaves to her accordingly."

"Believe me, I am only too anxious to get at the bottom of this dreadful business," Jack said earnestly, "and there is nobody more anxious than I am to get Claire outside the sphere of Anstruther's influence altogether. Still, I am quite willing to try. I will see Claire to-morrow, and tell her everything."

Lady Barmouth's face beamed with a delight that was almost childish. She looked and acted like one who had had a great weight taken off her mind. That Jack had come to a wise decision she felt certain. She was saying so, speaking very briskly and freely, when the lights of the room were extinguished by some invisible agency, and the apartment left in utter darkness save for the wood-fire which smouldered on the hearth.

"I do hope you have all finished," Lady Barmouth cried. "It is quite evident that my husband thinks so, or the lights would not have been extinguished by turning off the switch outside the door."

Both Jack and Rigby muttered something to the effect that they had finished. Lady Barmouth produced a tiny silver spirit lamp from the sideboard, the blue flame of which was little larger than a pin's point, sufficient to light a cigarette, but insufficient to illuminate a scrap of paper a foot away. In silence the cigarettes were handed round, and the well-trained voice of a servant was heard announcing Lord Barmouth. A closely muffled figure crept into the room, and proceeded to bury itself in a big armchair by the side of the wood-fire.

"These are my friends, Mr. Rigby and Mr. Masefield," Lady Barmouth said cheerfully. "I have told them that you would like to have a few words with them, George. You will find these gentlemen willing to speak quite freely."
