A waiter took his order for a gin and tonic as Fox relaxed in his chair. He would have to do his Project work now. He had nothing else he could do, and he would have to try his best. He just wished the war would be over before the question of using the atomic bomb—if they managed to develop it—ever came up.
Fox swallowed a mouthful of his gin and tonic. As his eyes grew accustomed to the dim light in the club, he spotted another person with the same out-of-place aura as the Nice Young Man from the bus, sitting in a corner and looking over the crowd. How long had he been there? Had he followed Fox all afternoon?
Feeling suddenly reckless, Fox raised his glass and toasted the G-2 man.
The man looked away.

Berlin—the Virus House
August 1943
“[Heisenberg] declared, to be sure, that the scientific solution had already been found and that theoretically nothing stood in the way of building such a .bomb.”
“German physicists had no desire to make atomic bombs, and were glad to be spared the decision by force of external circumstances.”
Gravel crunched under the wheels of the staff car as the driver turned off of the cobblestoned streets. They proceeded to a less-traveled area of the Berlin suburb of Dahlem, then turned down the damp road to the Kaiser-Wilhelm Institute. The stolid construction of the Institute for Chemistry and the Institute for Physics was overbearing, designed at the turn of the century to please the rigid tastes of the Kaiser. Now, in the August rain, the trees and the flower boxes appeared subdued. Wet streaks ran down the stone walls as water splashed out of rusting gutters.
The driver of the staff car activated the windshield wiper, but it merely smeared a thin film of mud. Ahead of the car rode two motorcycle guards hunched over their handlebars. The motorcycle engines popped and puttered from the alcohol fuel.
Although he now held the upper hand, Professor Abraham Esau fidgeted in the back of the staff car, wondering if he would triumph as planned or if everything would backfire on him. The drive had not been long, but it was uncomfortable. Reichminister Albert Speer sat beside him, straight-backed and silent, staring ahead. The Minister of Armaments must be preoccupied with something other than the secret Nazi research center known as the Virus House.
Beside the driver sat Major Wilhelm Stadt of the Gestapo, dressed in a black uniform with SS armband. Major Stadt was rude, fast spoken, with an air of confidence that bordered on impatience. As did so many of the young officers, the major sported a small toothbrush moustache like Hitler’s and Himmler’s. He had his pale hair shaved severely up around his ears and the back of his neck, making him appear to be wearing an overlarge Jewish skullcap. Esau did not dare make such a comparison aloud; the SS major would not have found it amusing.
Major Stadt spoke to the driver, telling coarse stories and Jewish jokes, acting friendly toward the lower ranks—after all, wasn’t Gestapo head Himmler himself a former chicken farmer? But Stadt’s casual attitude seemed a ploy to Esau, a practiced interrogation technique. Every third or fourth comment, Major Stadt would turn around to look at Reichminister Speer, as if searching for some reaction. Occasionally Speer would nod, or smile if that seemed appropriate, but he said few words.
Esau knew that Speer had never wanted his position as Minister of Armaments—he was an architect who had served Hitler well, but he had been astonished when Hitler promoted him after the previous minister had been killed in an airplane crash. Speer had done his best in the position, but the German war effort seemed to be flagging. Mussolini had been overthrown in Italy, and a humiliating and disastrous Allied bombing raid had just turned the city of Hamburg into a firestorm.
No matter. From Esau’s work here at the Kaiser-Wilhelm Institute, both he and Reichminister Speer could become heroes. The firestorm of Hamburg would be nothing compared to the devastation a German atomic bomb could deliver. The other scientists would not be so smug and uncooperative with Speer standing beside him. Esau now had the crowbar he needed to consolidate the nuclear physics research firmly under his own custodianship.
Werner Heisenberg would not be expecting them; Esau wanted that as part of their surprise. Heisenberg lived in Leipzig with his family, but took the train to Berlin twice a week to continue work at the institute. Esau had taken great care to be sure they arrived on a day Heisenberg would be at the Virus House.
The motorcycles ground to a halt. The staff car pulled up in front of a complex of wooden buildings surrounded by a gate and a sagging barbed-wire fence. One guard, wrapped in a rain shawl with a machine gun over his shoulder, stepped forward to inspect the papers of the motorcycle riders, who gestured him toward the staff car. The driver wrestled with the crank to turn down the window.
“This is a restricted area. May I see your papers please?” the guard said, pushing his head in and dripping water on the driver’s shoulder.
When he saw Reichminister Speer and Major Stadt in their respective uniforms, the guard stiffened, but held his ground. For security reasons they had not marked the staff car to announce the ranks of its occupants.
Major Stadt remained silent, and Esau waited as the guard checked them through. Any other behavior by the guard would not have been tolerated. The guard returned the folded papers to the driver, then trudged off through the mud back to his windbreak shelter beside the barbed-wire gate. The two motorcycle riders kicked their engines into life again, then proceeded through the gate. The driver of the staff car kept the window cracked open, allowing damp air to purge the atmosphere inside. They drove into the grounds of the Virus House.
In July 1940 the researcher Karl Wirtz had built a small laboratory on the grounds of the Kaiser-Wilhelm Institute for Biology and Virus Research, adjacent to the Institute of Physics. All power and water for the new establishment came from the institute’s large virus growth laboratories. But Dr. Karl Wirtz was no biologist. The ominous name “Virus House” was prominently displayed only to keep the curious away, and to mislead any spies about the actual research conducted there.
At the beginning of the war, Reichminister Speer’s predecessor had been skeptical about the nuclear physics program, since it then appeared the Blitzkrieg would give Germany victory over Britain long before nuclear physicists could develop a new weapon. Nevertheless, a research program was set up. The head of the institute, the Dutch experimental physicist Paul Debye, was told that he must either become a German citizen or leave his post, because no foreign national could be allowed to work on a secret military project. Debye had chosen to leave, departing to go on a “lecture tour” to neutral America.
That was in January 1940. The Armaments Ministry tried to install Dr. Kurt Diebner from the military as Debye’s replacement, and this the rest of the Kaiser-Wilhelm Institute resoundingly opposed. But they had not yet realized how much times had changed. Finally the institute accepted Dr. Diebner as a provisional head, until such time as Paul Debye returned from his lecture tour.
But Diebner’s career had not survived political machinations in the following years. Other scientists, such as Karl Wirtz and Carl-Friedrich von Weizsacker had schemed to draw Werner Heisenberg into the institute, where he became titular head of nuclear physics work-subordinate to the Plenipotentiary for Nuclear Physics, of course, Esau reminded himself.
Esau had been to the Virus House on official visits, but he had accomplished nothing. The program remained as scattered and uninspired as ever, the scientists more concerned with maintaining their reputations than with winning the war.
