"What did you go into the Pool for?" he asked.
"I fished about with a rake. I thought there might be some weapon or other trace. But how on earth—"
"Oh, tut, tut! I have no time! That left foot of yours with its inward twist is all over the place. A mole could trace it, and there it vanishes among the reeds. Oh, how simple it would all have been had I been here before they came like a herd of buffalo, and wallowed all over it. Here is where the party with the lodge-keeper came, and they have covered all tracks for six or eight feet round the body. But here are three separate tracks of the same feet." He drew out a lens, and lay down upon his waterproof to have a better view, talking all the time rather to himself than to us. "These are young McCarthy's feet. Twice he was walking, and once he ran swiftly so that the soles are deeply marked, and the heels hardly visible. That bears out his story. He ran when he saw his father on the ground. Then here are the father's feet as he paced up and down. What is this, then? It is the butt-end of the gun as the son stood listening. And this? Ha, ha! What have we here? Tiptoes! tiptoes! Square, too, quite unusual boots! They come, they go, they come again—of course that was for the cloak. Now where did they come from?" He ran up and down, sometimes losing, sometimes finding the track until we were well within the edge of the wood, and under the shadow of a great beech, the largest tree in the neighborhood. 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,
