Bob seized the knob and shook it violently. To no purpose, however.
"Get a chair, Hugh," he cried. "We'll smash the door in."
"How do we know what's waiting for us in the hall?"
"I don't care. We've got to get out of here."
There was a deafening report of a gun fired in the narrow hall. The panel of the door close to Bob's head was splintered, and a bullet shot across the room, shivering the one remaining pane of glass left in the window.
"Duck!" shouted Hugh. "Get away from that door!"
Bob needed no second urging. He sprang aside and cowered against the side of the wall. The two boys looked at each other, pale-lipped and breathing hard.
"Whew," exclaimed Hugh. "That was a close call."
Bob whipped his pistol out of his pocket, and began to crawl back toward the door.
"What are you going to do?" demanded Hugh in alarm.
