It started with a thin, high droning to the north. The familiar drone of aircraft. As always, under these circumstances, Dr. Mallory sounded the "Take cover!" signal, and everyone scurried to the shelter of the camouflaged grove, there to wait until the danger should pass.
But it did not pass. The droning came nearer, deepened in tone. And we saw, through the leafy veil that concealed us, that it was not a single plane that was approaching, nor a single flight—but a solid phalanx of enemy aircraft!
Even then we did not guess the dreadful truth. It was not until they had come directly over us, swung into an involute loop and began concentrating upon us, that we knew what was happening. Then we saw something dark and ominous loose itself from the rack of one bomber; a thin screaming filled the air—and in the woods to our right there came a frightful blast!

There was only one thing that spared all of us in those next few minutes. That was the fact that the Toties did not know exactly where we were. Somehow they had learned the approximate location of Dr. Mallory's mountain hide-away, but not in vain had the aged scientist spent twenty years nurturing plant life to form a perfect barricade of concealment about the dim, squat buildings. From above, the wooded dell that hid his laboratory must have looked like one of thousands such.
Therefore they scattered their shots. One bomb exploded a quarter mile from Mallory's house; I learned afterward that it killed two workmen who had been laying in cordwood. Others exploded as far as five miles away as the hive of lethal wasps eddied back and forth, bombing the entire countryside with abandon.
A thousand questions seethed through my brain, but there was no time now to ponder the answers. No time to ask why, or how, the Toties had learned of this place. I seized Maureen's elbow, half-led, half-dragged her toward the laboratory. Above the crashing din I howled in her ear, "To the cavern! That's the only safe—"
