Then he saw it disappear, as the light was moved to one side.

“That was Casco, sure,” he said to himself. “And, hello! there’s somebody else. I wonder who it is?”

Bob saw that the window of the room was directly over the one story addition in the rear. He wondered if he could not get up to it and find out what was going on within.

Looking around, he espied a short ladder resting against an apple tree. Catching up the ladder, he placed it against the addition, and found it just reached the roof above.

Making sure that he was not being observed, Bob mounted the ladder silently, and then made his way over the roof to where the window was located.

As it was a warm night in the summer, both the upper and the lower sashes were placed to admit the air, and, by putting his ear close to the lower opening, Bob was able to make out all that was being said within the room.

“You are certain the boy didn’t follow you?” he heard, in a rough voice.

“No, I’m not sure, Raymond,” came the reply, in the tones of Casco. “But though I looked back I didn’t see him.”

“Humph! He might even this minute be somewhere about this place. Maybe it would be better to take a look around.”

“I took a good look before I came in. He has either gone on to Kentown or farther, I’m satisfied.”
