The ginger was still talking through him, Ussmak thought. Landcruiser crews shouldn’t have taken any casualties from a nuisance machine gun. Besides which, Hessef was ignoring the disabled fighting vehicle and the delay that sprang from the little firefight. If you’d tasted ginger a while before, such setbacks were too small to be worth noticing. Had Ussmak tasted along with the rest of the crew, he wouldn’t have noticed them, either. Without a particle of the herb in him, though, they bulked large. He wondered just how clever he really was after a good taste.

From behind and to the left, bullets clattered off the landcruiser’s rear deck and the back of the turret. The Big Uglies at their machine gun had lived through the firestorm around them after all.

“Halt!” Hessef screeched. Ussmak obediently hit the brake. “Five rounds high explosive this time,” the commander ordered. “Do you hear me, Tvenkel? I want those maniacal males blown to bloody bits.”

“So do I,” the gunner said. He and his commander agreed perfectly, just as training said members of a landcruiser crew should. The only trouble was that the tactic on which they agreed struck Ussmak as insane.

The landcruiser’s main armament boomed, again and again. And Hessef’s was not the only crew that had halted. Through his vision slits, Ussmak watched several other landcruisers stop so they could pour fire down on the Tosevites who had had the temerity to annoy them. The driver wondered if their commanders were tasting, too.

When the barrage was done, Hessef said, “Forward,” in tones of self-satisfaction. Ussmak obeyed again. Not much later, the landcruiser column came to an enormous hole blown in the highway. “The Big Uglies can’t stop us with nonsense like that,” Hessef declared. And sure enough, the armored fighting vehicles’ swung off the road one by one.

The machine just in front of Ussmak’s rolled over a mine and lost a track. As soon as it slewed to a stop, a concealed Tosevite machine gun opened up. The landcruisers again returned fire with cannon and machine guns.

The column was very late reaching its assigned destination.

Heinrich Jager paced through the cobblestoned streets of Hechingen. Up on a spur of the Schwabische Alb stood Burg Hohenzollern. Its turrets, seen mistily through fog, made Jager think of medieval epic, of maidens with long golden tresses and of the dragons that coveted them for their own dragonish reasons.

The trouble these days, however, was Lizards, not dragons. Jager wished he were back at the front so he could do something useful about them. Instead, he was stuck here with the best scientific minds of the Reich.

He had nothing against them: on the contrary. They were far more likely to save Germany-to save mankind-than he was. But they thought they needed him to help them do it, and in that, as far as he could see, they were badly mistaken.

He’d watched soldiers make the same kind of mistake. If a detachment from the quartermaster’s office brought a new model field telephone to the frontline soldiers, they were automatically seen as experts on the gadget, even if the only thing they knew about it was how to get it out of its crate.

So with him now. He’d helped steal the explosive metal from the Lizards, he’d hauled it across the Ukraine and Poland. Therefore, the presumption ran, he had to know all about it. Like a lot of presumptions, that one presumed too much.

Coming up the street toward him, munching on a chunk of black bread, was Werner Heisenberg. In spite of the bread, Heisenberg looked very much the academic: he was tall and serious-looking, with bushy hair combed straight back, fluffy eyebrows, and an expression mostly, as now, abstracted.

“Herr Doktor Professor,” Jager said, touching the brim of his service cap. No matter how bored he was, he remained polite.

“Ah; Colonel Jager, good day. I did not see you.” Heisenberg chuckled uneasily. Being taken for the traditional absentminded professor had to embarrass him, not least because he really wasn’t that way. Up till now, he’d always seemed plenty sharp-and not just brilliant, which went without saying-to Jager. He went on, “I am glad to find you, though I must thank you again for the material you have given us to work with.”

“To serve the Reich is my pleasure and my duty,” Jager answered, politely still. If Heisenberg had ever seen combat, he didn’t show it. He could thank Jager for bringing the explosive metal, but he didn’t really know what that meant, or how much blood had been spilled to get him his experimental material.

He proceeded to prove that, saying, “A pity you could not have fetched us a bit more. Theoretical calculations indicate the amount we have is marginal for the production of a uranium explosive. Another three or four kilos would have been most beneficial.”

That did it. Jager’s boredom boiled away in fury. “Dr. Diebner had the courtesy to be grateful for what was provided rather than to complain about it. He also had the sense, sir”-Jager loaded the title with scorn-“to remember how, many lives were lost obtaining it.”

He’d hoped to make Heisenberg ashamed. Instead, he flicked him on his vanity. “Diebner? Ha! He has not even his Habilitation. He is, if you ask me, more tinkerer than physicist.”

“He knows what war entails, which is more than you seem to. And, by all accounts, he and his group are further along than yours in setting up the apparatus to produce more of this explosive metal for ourselves after we expend what we procured from the Lizards.”

“By no means is his work theoretically sound,” Heisenberg said, as if he were accusing the other physicist of embezzlement.

“I don’t care about theory. I care about results.” Jager automatically reacted like a soldier. “Without results, theory is irrelevant.”

“Without theory, results are impossible,” Heisenberg retorted. The two men glared at each other. Jager wished he hadn’t bothered to greet the physicist. By the expression on his face, Heisenberg wished the same thing.

Jager shouted, “The metal is more real to you than the men who fell getting it.” He wanted to clout Heisenberg down from his cloud, make him glimpse, however distantly, the world beyond equations. He also wanted to kick him in the teeth.

“I tried to express to you a civil good day, Colonel Jager,” Heisenberg said in tones of ice. “That you’return it to me with such, such recriminations I can take only as the mark of an unbalanced mind. Believe me, Colonel, I shall trouble you no further.” The physicist stalked off.

Still steaming, Jager stalked, too, in the opposite direction. He jumped and almost grabbed for his sidearm when someone said, “Well, Colonel, what was that in aid of?”

“Dr. Diebner!” Jager said. “You startled me.” He took his hand away from the flap of his holster.

“I shall try not to do that again,” Kurt Diebner said. “I can see it might not be healthy for me.” Where Heisenberg looked like a professor, Diebner at first glance seemed more likely to be a farmer. He was in his thirties, with a broad, fleshy face and a receding hairline which he emphasized by slicking down his dark hair with grease and combing it straight back. He wore his baggy suit as if he’d been out walking the fields in it. Only the thick glasses that showed how nearsighted he was argued for a different interpretation of his character.

Jager said, “I had a-disagreement with your colleague.”

“I saw that, yes.” Behind the glasses, amusement glinted in Diebner’s eyes. “I don’t believe I have ever seen Dr. Heisenberg so provoked; he normally cultivates an Olympian imperturbability. I came round the corner only for the tail end of the-disagreement, you said? — and was wondering what touched it off.”

The panzer colonel hesitated, since his compliments for Diebner had helped set Heisenberg off. At last he said, “I was concerned that Professor Heisenberg did not, ah, fully realize the difficulties in getting this metal to you nuclear physicists so you could exploit it.”
