"Trying to lay that stuff a bit!" he shouted. "Okay! Here comes your end of the rope."

He sent the free end of the coil spinning downward, then knelt down and fastened his end tight about the base of the railing post.

"Got it!" he heard the fire lieutenant's voice, and felt a jerk on the rope at the same time.

At the end of three or four minutes Freddy and the fire lieutenant were on the floor landing with him. The fire lieutenant reached out and squeezed his arm.

"Stout fellow," the man said. "But you're R.A.F., so of course you'd do it. Right-o. This is the fourth floor. The rear, you said? Don't hear a sound. And there doesn't seem to be much fire up here. Guess just the front of this place is burning. Try the doors, lads, but be careful as you push them open. Do it easy like, you know. If the room's burning and the windows are closed, opening the door will be like opening a stove flue. Hold your breath until you're sure. Let's go."

The three of them started down the hall toward the rear, carefully opening doors and glancing into rooms as they went along. Not a light was burning in the building, but the glow of the flames seemed to bounce back from the walls of nearby buildings and light up all the rooms. Dave and Freddy had tried some six or seven rooms when suddenly they looked into a room that made them stop short and catch their breath.

The room was a complete wreck. It was as though that one spot had received the full impact of the exploding bomb. All four walls were completely knocked down. Ribbons of plaster hung from the ceiling, and there weren't any windows, just gaping holes through which streamed the crimson reflection of the flames of another burning building a good two blocks away.

It was not the sight of all that, however, that gave them such a start. It was the sight of the four figures trapped under the pile of debris. Three were men, and one was a woman. Two of the men, and the woman, lay limp and motionless. The fourth man, white with plaster from head to foot, was struggling furiously to wiggle out from under an overturned desk that pinned him to the floor. And all the time he was muttering hoarsely under his breath. He saw Dave and Freddy about the same instant they saw him. He stopped struggling instantly.

"Come in, chaps, and get this blasted thing off my back, will you?" he called out.

Dave waited just long enough to shout to the fire lieutenant and then dashed forward. It took every bit of their combined strength for Freddy and him to lift the desk clear. They succeeded, however, and the pinned man was able to crawl free. He got to his feet and swayed drunkenly. Dave gave him a hand.
