a little distance along the lake shore. Suddenly he saw, looming up in the forest, a large building. It needed but a glance to show that it was falling into ruins, and had no signs of life about it. Nor, for that matter, was there any life in the forest around him, or on the lake that stretched out before him.
"I wonder if that can be the place?" whispered Tom, for, somehow, the silence of the place was getting on his nerves. "It must be it," he went on. "It's just as Rad described it."
He stood looking at it, the sun striking full on the mysterious mansion, hidden there amid the trees. Suddenly, as Tom looked, he heard the "put-put" of a motor-boat. He turned to one side, and saw, putting out from a little dock that he had not noticed before, a small craft. It contained one man, and no sooner had the young inventor caught a glimpse of him than he cried out:
"That's the man who jumped over our fence and escaped!"
Then, before the occupant of the boat could catch sight of him, Tom turned and fled back into the bushes, out of view.
