"Thanks, very much," he said in a tight voice.

"Thanks?" Dave murmured. "For what?"

"For reminding me to keep away from windows during a bombing raid," Freddy said. "But just before that blighter scared ten years off my life, what were you saying? Oh, yes. You want to go up on the roof?"

"Sure," Dave said with a nod. "For a look. We'll be as safe there as any place. If one's coming, it'll come. Just standing here waiting gives me the creeps, anyway."

"Me, too," Freddy agreed. "Let's go, then. Bet the manager's in the raid shelter, though, and won't dig up tin helmets for us for love nor money."

"Well, we can try," Dave said. "And—Drop, Freddy! Here comes another!"

Dave's words of warning were just a waste of breath. The screaming whistle of that bomb hurtling downward cut through all sound. As Dave flung himself flat again, he had the crazy feeling of listening to some huge invisible giant tearing off the top of the world. Even the anti-aircraft battery close to the hotel was drowned out by the unearthly sound of that falling bomb. Then it struck, and the hotel seemed to rise right straight up in the air. Dave was sure he could feel the floor heave under him. He closed his eyes tight, and held his breath. For a long moment everything seemed to stop dead. Then the hotel settled back like something alive but so very, very tired. A second later there was a short series of sharp cracking sounds, and ceiling plaster fell down on the two R.A.F. pilots.

"That baby was trying to mean business!" Dave said, and got to his feet again. "Hitler must know we're in town, the way so many of them are coming close. Hey, that did hit close. The building next door!"

The hole where the window had been was now like the entrance to a long blazing tunnel. Thirty feet away the three upper floors of a building were blazing fiercely. And when the two boys leaped over to the window hole, they saw that the entire front of the building had been torn away by the terrific blast. In the glow of the flames they could see right into rooms full of broken and mangled furniture and apartment furnishings. On the rear wall of one room was a framed picture of King George and Queen Elizabeth. Everything else in the room was wrecked beyond possible recognition by its owners, but the picture of the King and Queen was untouched. It hung on the blast-scorched wall as straight as could be.

Something about that picture hanging there touched a note deep in Dave Dawson. He stared at it for a moment in almost reverent awe. Then, clicking his heels, he brought his hand up in smart salute.
