"I know we are dealing with mere possibilities as yet, sir. But these possibilities are much more credible than the surmises in which we have hitherto indulged. I feel as if free air had entered my lungs for the first time since the inquest; and if I can refrain from yielding too much to the intoxication of it——"

"But," I again repeated, determined to have my say out before he had gone too far, "what motive can you ascribe to this poor old servant for a death which robbed him of a master he had served devotedly for years?"

"Motive be ——!" cried Sweetwater, in some heat. But, with his usual good nature, he instantly begged my pardon, and his next words were uttered with more restraint. "Facts first, motives afterwards. What motive have we been able to find for the committal of this deed by any one of his sons? Yet each and all of them have been suspected and almost arraigned. Still," he concluded, "if you want a motive, search for it here," and he drew from his pocket a second folded paper, which he opened out before my eyes.

It was a copy of Mr. Gillespie's will.

"Ah!" I cried, in dim perception of what he meant.

"A thousand dollars," explained Sweetwater. "Not much in your eyes, but quite a fortune in his."

"And for so paltry a legacy you think that this man——"

Sweetwater's finger went to his lips. "Excuse me," said he, "but had we not better put back this typewriter on the shelf from which we took it? If I do not mistake, it will figure largely in the trial which I plainly see approaching."

I nodded, recognising the wisdom of the admonition thus given, and together we placed the typewriter back in the closet. Then he turned towards me with a new light in his small grey eye.

"And now, sir," he cried, "let me request you to stand back a trifle. I am going to finish this business."
