So the two eldest Bunker children crouched down on the side porch, under the dining-room windows, and listened to the talk that was going on inside. Of course this was not right, but they did not know any better, especially after Grandpa Ford spoke about a "riddle."

And so it came about that Rose and Russ heard what it was not intended they should hear.

"You know," went on Grandpa Ford, as Russ and Rose listened outside, "that I bought Great Hedge Estate from a Mr. James Ripley, who lives near here."

"Yes, I know that," said Daddy Bunker. "Well, you like it, don't you, Father?"

"Quite well. Your mother likes it, too. It is a large farm, as you know, and there is a big stretch of woods, as well as land where I can raise fruits and vegetables. There are meadows for grazing, and fields for corn, hay and oats. Great Hedge is a fine place, and your mother and I like it there very much.

"We were a bit lonesome, at first, as it is large, but we hope to get over that part in a little while.

"What brought me down here is to see Mr. Ripley, and find out something about the place he sold me. I must find out something about Great Hedge."

"Here is where the riddle comes in," said Russ in a whisper to his sister. "We must listen hard now."

"What do you want to find out about Great Hedge, Father?" asked Daddy Bunker. "Do you think you paid too much for it?"

"No, I got it very cheap. But there is something queer about it, and I want to find out if Mr. Ripley can tell me what it is."
