"He is goodness and kindness itself," Lady Barmouth said warmly. "He has always insisted that his misfortunes should not interfere with my personal enjoyment. At a dinner, or a reception, or an ordinary dance, my husband never shows himself. Despite his terrible misfortunes he thoroughly enjoys his amusements; he likes to mingle with people, seeing everything, and not being seen himself. That is why I give so many of these masked balls. This is going to be an extra smart affair, and I am asking my lady friends to wear as many jewels as possible."

"Claire told me something about it," Jack said. "I gathered that she is to be one of the invited guests."

"I am asking both Miss Helmsley and Mr. Anstruther," Lady Barmouth explained. "There is some danger in asking the latter, but one has to take these risks."

Jack murmured something that sounded sympathetic. Had Lady Barmouth only known it, the risk was far greater than she imagined. If Jack's suspicions were correct that Anstruther was mixed up with a gang of expert thieves, here then was a golden opportunity. The mere fact of it being a masked ball simply added to his opportunities. So deeply did Jack ponder over this, that it was some little time before he grasped the fact that Lady Barmouth was still giving him details of the forthcoming function.

"I am asking a lot of most prominent actresses," she said , "together with a number of leading musicians, and they are getting up a kind of morris dance. Of course, the music will be supplied by a small band of famous artists, and I am getting this new man Padini to be present."

Here was more news with a vengeance. But there was nothing to be gained by telling Lady Barmouth what had been elicited with regard to Padini.

"I presume I shall be honored with an invitation," Jack suggested. "I see from the expression of your face that I am to be a guest. Might I beg the favor of a card for a friend of mine?"

"More mysteries!" Lady Barmouth laughed. "Oh, you need not tell me unless it is absolutely necessary. You shall take the card away with you if you like, and deliver it to your friend personally."

Jack was seeing his way pretty clearly by this time. He was anticipating more than one important discovery during the progress of the masked dance. The card he had begged was, of course, for Rigby, and it would go hard if between them they did not discover something of importance.

"Now, I am going to speak to you on a more or less painful topic," Jack said gravely. "And I am going to ask you to be exceedingly candid with me. I want you to tell me what is the exact connection between Lord Barmouth and the Nostalgo posters which are so prominent in London at present."
