"Very well, Mr. Hardwick," Hewitt replied; "you'll do what you consider your duty, of course, and quite properly, though I would recommend you to take another glance at those three trails in the path. I shall take a look in this direction." And he turned up by the side of the streamlet, keeping on the gravel at its side.
I followed. We climbed the rising ground, and presently, among the trees, came to the place where the little rill emerged from the broken ground in the highest part of the wood. Here the clean ground ceased, and there was a large patch of wet clayey earth. Several marks left by the feet of cattle were there, and one or two human footmarks. Two of these (a pair), the newest and the most distinct, Hewitt studied carefully, and measured each direction.
"Notice these marks," he said. "They may be of importance or they may not—that we shall see. Fortunately they are very distinctive—the right boot is a badly worn one, and a small tag of leather, where the soul is damaged, is doubled over and trodden into the soft earth. Nothing could be luckier. Clearly they are the most recent footsteps in this direction—from the main road, which lies right ahead, through the rest of the wood."
"Then you think somebody else has been on the scene of the tragedy, beside the victim and the brothers?" I said.
"Yes, I do. But hark; there is a vehicle in the road. Can you see between the trees? Yes, it is the police cart. We shall be able to report its arrival to Mr. Hardwick as we go down."
We turned and walked rapidly down the incline to where we had come from. Mr. Hardwick and his man were still there, and another rustic had arrived to gape. We told Mr. Hardwick that he might expect the police presently, and proceeded along the gravel skirting the stream, toward the lower part of the wood.
Here Hewitt proceeded very cautiously, keeping a sharp look-out on either side for footprints on the neighbouring soft ground. There were none, however, for the gravel margin of the stream made a sort of footpath of itself, and the trees and undergrowth were close and thick on each side. At the bottom we emerged from the wood on a small piece of open ground skirting a lane, and here, just by the side of the lane, where the stream fell into a trench, Hewitt suddenly pounced on another footmark. He was unusually excited.
"See," he said, "here it is—the right foot with its broken leather, and the corresponding left foot on the damp edge of the lane itself. He—the man with the broken shoe—has walked on the hard gravel all the way down from the source of the stream, and his is the only trail unaccounted for near the body. Come, Brett, we've an adventure on foot. Do you care to let your uncle's dinner go by the board, and follow?"
"Can't we go back and tell him?"
"No—there's no time to lose; we must follow up this man—or at least I must. You go or stay, of course, as you think best."
