"Not a bit of it," Lord Ellerdine replied, shaking hands with the expert. "Glad to see you, Mr. Devereux. No; it is something far more important than a cheque for fifty pounds. It is to do with the Admaston divorce case."

Mr. Devereux started. His face became almost ferret-like in its intentness, while he said nasally, but with suppressed eagerness in his voice, "I guess this is a bit of luck. I have just seen this evening's paper, and of course I have followed the case with great interest from first to last. I know without any possibility of doubt that all my brother experts in London have been consulted. And from the first it has rather hurt me that nobody had come to me, because I do claim——"

Lord Ellerdine interrupted him. "I know, I know," he said; "there is no one that can touch you, Mr. Devereux. But probably, you see——" He hesitated in his effort to soothe the somewhat wounded feelings of the expert.

Colonel Adams came to the rescue. "Well, Mr. Devereux," he said, "here we are, and we have got something very important on which to ask your opinion."

The expert became all attention once more. "What is it?" he said briefly.

Lord Ellerdine put his hand in the breast-pocket of his coat and withdrew a long envelope full of papers.

"I have here," he said, "exact photographs and tracings—everything that you will probably find needful, in fact—of the two letters which you have just been reading about in the evening paper, and which have caused such a tremendous sensation this afternoon. It seems at the moment that Mrs. Admaston has absolutely lost her case. To all outward appearances these letters have ruined her. At the same time, I am certain that she knew nothing about them, and that Mr. Collingwood knew nothing about them either. You follow me?"

Lord Ellerdine had never been so concise and explanatory before, but the occasion had come, and he had risen to it.

"I follow you perfectly," said the expert.

"Very well, then," Lord Ellerdine said; "here are the letters, and I want you to tell me what you think about them."
