"Oh, what is the use of wasting your time and mine like this?" Lady Barmouth cried. "My brother came here by special appointment to meet Mr. Spencer Anstruther, and I came on my own self-initiative to see what my brother was doing."
Here was fresh information for Jack and his companion. It mattered little for the present who Lady Barmouth's brother was, but evidently she had greatly mistrusted him; hence her appearance in the courtyard to-night. It was, therefore, by no means difficult for the friends to guess that the aforesaid brother had been the man who had so lately accused Lady Barmouth of being a sentimental fool. The night's work was being by no means wasted.
"I know nothing whatever about your brother," Redgrave said sulkily, "and I know nothing about Anstruther either. The man who was here just now--the man who made that murderous attack on me, I mean--was a perfect stranger. But this is no place for a lady like you; you had better go home, and keep out of this sort of scrape for the future.
"So saying, Redgrave scrambled painfully to his feet, and lurched off in the direction of the doorway leading to the lane beyond. It was only when they were satisfied that he had absolutely departed, that Rigby and Masefield emerged from their hiding place and joined Lady Barmouth. There was a sad, wistful expression on her face.
"You heard all that," she said . "Mind you, I am assuming that you are no parties to the vile conspiracy of which Anstruther is the head. I should like to have your assurance on that point before I proceed any further."
"If there is one man in the world whom we desire to expose and render harmless for the future, it is Spencer Anstruther," Jack said vehemently. "But how did you know we were here at all?"
"Because I happened to be in the house when you came," Lady Barmouth explained. "I caught sight of your faces as you moved in front of the light proceeding from that room up-stairs, and I divined by a sort of instinct that you did not belong to Anstruther's gang. Then it came to me that I had seen one of you gentlemen before in the company of Miss Helmsley. I think, sir, I may be pardoned if I assume that Miss Helmsley is something more than a friend of yours."
"To be perfectly candid with you, we are engaged to be married, only it is a profound secret at present," Jack explained. "After telling you so much, I think you might be equally candid with us."
"Indeed I will!" Lady Barmouth exclaimed. "Any one to whom Claire Helmsley has given her heart must be a good and true man. As I told you just now, I saw you on the stairs; I also heard what that strange man said about there being spies in the house; I saw you creep into the room, and I saw Anstruther lock the door upon you. The rest you know for yourselves."
"But that does not explain why you are here," Rigby ventured to suggest.
