Cleek turned and looked inquiringly at the General.

"Yes, certainly, Mr. Barch, certainly," he said, replying to that look. "The instrument is in the library, which opens directly off my study. Hamer will show you the way."

"No, I will," put in Ailsa. "I shall have to be running up to see how Kathie is, and it will be on my way. Good-night, Sir Philip. Good-night, General. Come, Mr. Barch, I'll show you the way." She went with him out of the moonlight in the open to the dark of the shrubbery and the trees that shut in the path to the house.

"Tell me," she whispered eagerly as they hurried along. "Are you nearer the end? Is the solution anywhere in sight?"

"I think so," he answered.

"Oh!" with a sharp intaking of the breath. "You found it out at the garden door, then? You saw the woman and you saw the person she came to meet?"

"To the contrary, I saw neither. I merely heard the woman speak. It was a voice I had never heard before. The man said nothing, and never once showed himself. He might have done both but that they heard you returning and separated like a shot. But please, we will not speak of that at present. Wait for me by the shrubbery; I'll tell you a lot when I meet you there. Just now I am anxious to know who it is that is telephoning to 'Mr. Philip Barch' and for what. Only two persons outside of Dollops and yourself know that name and whose identity it covers. One is Geoffrey Clavering, the other Mr. Narkom. No, please! Don't ask me any questions now, I can't stop to answer them. But this you may know if it will ease your mind at all: Lady Katharine Fordham never had anything to do with it, although she was there. Oh, yes, she was, Miss Lorne; for all your protestations, I tell you that she was! And, what is more, I know the man, although I do not as yet know the motive!"

"Oh! You found it out, then, at the garden door?"

"No, I did not. I daren't stop to explain, but believe me, Miss Lorne, I begin to see light. I only wonder at one thing: What makes Sir Philip Clavering use black cosmetic? Sheer vanity, I suppose."

"Does he?" cried Ailsa, in surprise.
