And the next to come in was Tamlyn. Closing the door, he walked up to the hearthrug where we stood, and stirred the fire into a blaze.

“I am telling Johnny Ludlow that this story of Miss Deveen’s emeralds has made an unfavourable impression on me,” quoth Dr. Knox to him. “It does not appear to me to be at all clear that Lettice Lane did not take them; and that Miss Deveen, in her benevolence, screened her from the consequences.”

“But, indeed——” I was beginning, when Dr. Knox stopped me.

“A moment, Johnny. I was about to add that a woman who is capable of one crime can sometimes be capable of another; and I should not be surprised if it is Lettice Lane who is tampering with Lady Jenkins.”

“But,” I repeated, “Lettice Lane did not take the jewels. She knew nothing about it. She was perfectly innocent.”

“You cannot answer for it, Johnny.”

“Yes, I can; and do. I know who did take them.”

You know, Johnny Ludlow?” cried old Tamlyn, while Dr. Knox looked at me in silence.

“I helped Miss Deveen to find it out. At least, she had me with her during the progress of the discovery. It was a lady who took the jewels—as Miss Cattledon told you. She fainted away when it was brought home to her, and fell on my shoulder.”

I believe they hardly knew whether to give me credit or not. Of course it did sound strange that I, young Johnny Ludlow, should have been entrusted by Miss Deveen with a secret she would not disclose even to her many years’ companion and friend, Jemima Cattledon.
