Tommy made his way under the empty and sat listening, his ear almost against the bottom of the car. Presently he heard a movement above and then it seemed to him that something of considerable weight was being dragged across the floor. This was followed in a moment by a slight groan, and then a shadowy figure leaped from the open side door and started away in the darkness.
Now Sandy had been warned to hang onto the third boy like grim death if he caught sight of him. He saw this figure bounce out of the car and start, away. Therefore, he promptly reached out a foot and tripped the unknown to the ground.
He fell with a grunt of anger and pain and lay rolling on the cinders which lined the roadbed for a moment without speaking. In the meantime, Tommy had crawled out from under the car and stood ready to seize any second person who might make his appearance.
Almost immediately a second body came bouncing out of the empty.
Instead of starting away on a run, however, the second person stopped where Sandy stood beside the wiggling figure and looked down upon it.
"Hand him one!" he said in a boy's voice.
"Who is it?" asked Sandy.
"Don't know!" was the reply.
"What was he doing to you?"
"He was trying to rob me!"
