The demons in the broker's eyes glowered murderously along the sights of the leveled weapon. It seemed as though nothing could save the cowboy.

At just that moment, however, a window behind the broker crashed inward. A stone, hurled by Ping with all his force, had shattered the glass, plunged across the gap, and struck Murgatroyd's arm.

The arm dropped as though paralyzed, and the broker staggered sideways with a cry of pain. McGlory sprang upon him, and the two were struggling fiercely when Ping raced into the room and took a hand in the battle.

Murgatroyd, with only one hand, was no match for his wiry young antagonists.

As Newt and Murgatroyd had overpowered Matt, so the cowboy and the Chinaman wrestled and secured the advantage of Murgatroyd.

One of the forms on the floor slowly lifted itself and became busy with the cords around Matt's wrists.

"I can do the rest, Newt," said Matt, sitting up and freeing his ankles.

A few moments more and the tables had been completely turned. Murgatroyd was now the prisoner, and the king of the motor boys and his friends were in command of the situation.
