Holmes traced his way to the farther side of this and lay down once more upon his face with a little cry of satisfaction. For a long time he remained there, turning over the leaves and dried sticks, gathering up what seemed to me to be dust into an envelope and examining with his lens not only the ground but even the bark of the tree as far as he could reach. A jagged stone was lying among the moss, and this also he carefully examined and retained. Then he followed a pathway through the wood until he came to the high road, where all traces were lost.

“It has been a case of considerable interest,” he remarked, returning to his natural manner. “I fancy that this grey house on the right must be the lodge. I think that I will go in and have a word with Moran, and perhaps write a little note. Having done that, we may drive back to our luncheon. You may walk to the cab, and I shall be with you presently.”

It was about ten minutes before we regained our cab and drove back into Ross, Holmes still carrying with him the stone which he had picked up in the wood.
