"Who?" demanded Ben sullenly.

"Your little brother, Will."

Willie Alvord was only between four and five; not yet old enough to go to school.

"I got it all out of the baby this afternoon," continued Mrs. Alvord. "I saw him playing with a new baseball bat, and I made him tell me where he got it. It seems that Willie heard you and Toby, and the other boys talking about your Hallowe'en pranks yesterday morning before you went to school. Then, later, Willie was out in the street playing, when 'a nice man'—as Willie called him—came along and got to talking with him. The man talked about you, it seems, Ben, and he made believe he didn't think Willie's big brother was very smart. Then Willie up and boasted of your smartness down at the railroad. The 'nice man' took Willie to the corner and bought him some candy and a baseball bat, and kept on talking about you and Toby, and the rest, and of course Willie told the 'nice man' all he'd heard about the railroad business."

"That 'nice man' must have been the detective," growled Ben. "Oh, he's a real 'nice man.' If Willie was larger I'd take the baseball bat to him for talking too much!"

"Well, you won't," warned his mother dryly. "Willie is only a baby, and didn't know what he was saying. But you'd better go and apologize to Dick Prescott."

"Huh!" was Ben's undutiful retort. Then he went outside with Toby.

"So Dick didn't tell?" mused Toby. "It was your kid brother?"

"Don't you tell that to any one!" warned Ben Alvord, flushing.

"Why, you'll have to tell it yourself," protested Toby. "You'll surely have to beg Dick Prescott's pardon after what you said to him before the whole crowd. If you don't, then I'll tell myself. I'm not going to see Dick blamed for what he didn't do."
