At first I had thought I would not land upon the estate, but that I would beach the canoe at the other side of the wall. But changing my mind, I landed on the shore directly in front of the library, which was some hundred feet away upon the hill. I pulled the canoe upon the land, half hiding it behind the low-hanging branches of a willow tree. Then I started across the grass. Passing round the front of the library, I saw that the door was shut and the blinds at the windows. I did not pause, but went down the other side of the hill, through a clump of trees, until I reached the rear wall. The wall was some hundred yards away from the library, and the boy had said that he had seen the man in a direct line with the building. It was a granite wall almost ten feet high. I wondered a moment how I was going to get over it. A near-by tree, which had a branch hanging a few feet over the top of the wall, solved the difficulty. I climbed the tree, crept out on the branch, and dropped to the top of the wall. There I sat a moment to get my bearings. Behind me stretched the grounds of the murdered scientist, the many trees hiding all but the top of the house. Directly back of me was the summer house, where we had found the body. But to my surprise, when I turned and looked in the other direction, I found that in front there was a slight hollow—a mass of tangled underbrush and small trees. Beyond this stretched a pasture, losing itself in the woods some little distance away. The underbrush below me ran the entire length of the wall, but stopped on my right where the wall ended. In fact here the ground rose a few feet to a grass lined meadow. As I looked at the mass of trees and shrubs, the more I began to wonder what any one had been doing on the wall. It was not the way to leave the grounds, for the person would have been forced to climb the smooth stones. And then there was nothing but the distant woods and the field. I wondered if the boy had been right when he said the man had thrown something away. My eyes came again to the slight hollow below me. It was a tangled mass of shrubbery, with high grass, only hidden by the small trees which grew to the height of about eight or nine feet. To try and find anything in that tangle seemed impossible. But after a moment I dropped from the wall and started to make my way through the underbrush. It was even worse than I had expected. The ground was soft because of a spring which must have been near by. Not only were the trees thick, but there was a tangle of wild rosebushes. Their thorns clung to me as I tried to push my way through the bushes. Long before I reached the other side I realized that it was too late to expect to make any kind of a search. It had begun to be dusk by the time I reached the wall, and when I plunged into the underbrush, the thick foliage made it impossible to see.
