"Here," he said, "what are you following us for?"
The man tried to free himself, but Hal held him tight.
"If you'll let me loose, I'll explain," he said finally.
Hal considered this a moment; then with a shrug of his shoulders released his hold.
"Stand behind him, Chester," he said.
Chester followed Hal's injunction, but the man made no effort to escape.
"Well?" said Hal, questioningly.
The man thrust a hand into his pocket.
"Hold on there!" cried Hal, sharply, producing his revolver. "No tricks now."
The man smiled and withdrew his hand from his pocket.
