Inside the office, one of Pickering's engineers was sitting on the middle of his spinal column, a stenograph-phone in one hand and a book in the other. Once in a while, he would say something into the mouthpiece of the phone. Two other nuclear engineers had similar books spread out on a desk in front of them; they were making notes and looking up references in the Nuclear Engineers' Handbook, and making calculations with their slide-rules. There was a huddle around the drafting-boards, where two more such books were in use.

"Well, what's happened?" he demanded, catching Pickering by the arm as he rushed from one group to another.

"Ha! We have it!" Pickering cried. "Everything we need! Look!"

He had another of the books under his arm. He held it out to von Schlichten, and von Schlichten suddenly felt sicker than he had ever felt since, at the age of fourteen, he had gotten drunk for the first time. He had seen men crack up under intolerable strain before, but this was the first time he had seen a whole roomful of men blow their tops in the same manner.

The book was a novel—a jumbo-size historical novel, of some seven or eight hundred pages. Its dust-jacket bore a slightly-more-than-bust-length picture of a young lady with crimson hair and green eyes and jade earrings and a plunging—not to say power-diving—neckline that left her affiliation with the class of Mammalia in no doubt whatever. In the background, a mushroom-topped smoke-column rose, and away from it something intended to be a four-motor propeller-driven bomber of the First Century was racing madly. The title, he saw, was Dire Dawn, and the author was one Hildegarde Hernandez.

"Well, it has a picture of an A-bomb explosion an it," he agreed.

"It has more than that; it has the whole business. Case specifications, tampers, charge design, detonating device, everything. Why, end-papers even have diagrams: copies of the original Nagasaki-bomb drawing. Look."

Von Schlichten looked. He had no more than the average intelligent layman's knowledge of nuclear physics—enough to recharge or repair a conversion-unit—but the drawings looked authentic enough. They seemed to be copies of ancient blueprints, lettered in First Century English, with Lingua Terra translations added, and marked TOP SECRET and U. S. ARMY CORPS OF ENGINEERS and MANHATTAN ENGINEERING DISTRICT.

"And look at this!" Pickering opened at a marked page and showed it to him. "And this!" He opened where another slip of paper had been inserted. "Everything we want to know, practically."

"I don't get this." He wasn't sick, any more; just bewildered. "I read some reviews of this thing. All the reviewers panned hell out of it—'World War II Through a Bedroom Keyhole'; 'Henty in Black Lace Panties'—that sort of thing."
