"Well," resumed Carrington, "the simple facts of the case are these. I have been engaged through a certain firm of London lawyers, whose name I am not permitted to mention, on behalf of a person whose name I don't know."

At this a flash of keen interest showed for an instant in Simon's eye; and then it became as cold as ever again.

"Indeed?" said he.

"I am allowed to incur expense," continued the other, "up to a certain figure, which is so handsome that it gives me practically a free hand, so far as that is concerned. On the other hand, the arrangement entails certain difficulties which I daresay you, Mr. Rattar, as a lawyer, and especially as a Procurator Fiscal accustomed to investigate cases of crime, will readily understand."

"Quite so; quite so," agreed Mr. Rattar, who seemed to be distinctly relaxing already from his guarded attitude.

"I arrived last night, put up at the Kings Arms—where I gathered beforehand that the local gossip could best be collected, and in the course of the evening I collected enough to hang at least two people; and in the course of a few more evenings I shall probably have enough to hang half a dozen—if one can believe, say, a twentieth of what one hears. This morning I strolled out to Keldale House and had a look at it from the road, and I learned that it was a large mansion standing among trees. That's all I have been able to do so far."

"Nothing more than that?"

Mr. Carrington seemed to have a singularly short memory.

"I think that's the lot," said he. "And what is more, it seems to me the sum total of all I am likely to do without a little assistance from somebody in possession of rather more authentic facts than my friend Miss Peterkin and her visitors."

"I quite understand," said the lawyer; and it was plain that his interest was now thoroughly enlisted.
