"That is indeed good of you." The deep, clear ringing voice came from the fireplace. "I have been praying for something like this for the last twelve months. Still, it is more with Mr. Masefield than Mr. Rigby that I wish to speak. You have made a great discovery to-night, I understand. You have found out the source of those Nostalgo posters?"

"I think I have done more than that," Jack explained. "I have not only discovered their source, but I know where they are printed, and the process of their manufacture. If you like to put yourself in my hands and accompany me to-morrow night, you shall see the whole scheme for yourself."

Lord Barmouth was of opinion that it was not wise in the circumstances to take any such step. He cross-examined Jack at considerable length, his questions being pointed with marked intelligence. At the same time he said little or nothing about himself. Lady Barmouth sat there smiling behind the cover of the darkness, infinitely glad to see her husband taking an interest in the affairs of life once more.

"Don't you think it is rather late to-night?" she suggested; "besides, we are going too fast. With your intimate knowledge of the situation, and with the help of these gentlemen, surely we can devise some scheme for getting the better of that fiend Anstruther."

"Ay, you are right," Barmouth said, his deep voice ringing through the room. "I see a way now, a way as clear as daylight."

In his passionate emotion he dashed his foot forward so that the point of his shoe came with force against one of the logs in the grate. A blue flame spurted up, and died as suddenly as it had come. Jack and Rigby rose to leave. No sooner were they outside than Jack clutched his companion's arm eagerly.

"Did you see nothing?" Jack whispered. "By heaven, Lord Barmouth and the Nostalgo we saw in the forecourt to-night are one and the same person!"

[CHAPTER XVII.]

WHICH MAN WAS IT?

Rigby's astonishment was frank and undisguised. It was quite evident that he had noticed nothing suspicious about the look or attitude of Lord Barmouth; indeed, he had been on the far side of the table when the master of the house had entered the room. But he was not altogether prepared to accept Jack's statement unless he could verify it by something more than a mere expression of opinion.
