Tanzler's mood changed instantly. "So," he declared with precision. "I thought as much. Everyone knows you are working night and day, even though there is no need for it." Tanzler resurrected a chuckle. "We are not in any great hurry now. It's not as if we were pressed by anyone. The Australians and Canadians are fenced off by our navy. The Americans have their hands full in Asia. And your project, whatever it may be, will help no one if you kill yourself with overwork." "You know there is no project," Professor Kempfer whispered. "You know it is all just busy work. No one reads my reports. No one checks my results. They give me the equipment I ask for, and do not mind, as long as it is not too much. You know that quite well. Why pretend otherwise?" Tanzler sucked his lips. Then he shrugged. "Well, if you realize, then you realize," he said cheerfully. Then he changed expression again, and laid his hand on Professor Kempfer's arm in comradely fashion. "Jochim. It has been fifteen years. Must you still try to bury yourself?" Sixteen, Professor Kempfer corrected, and then realized Tanzler was not thinking of the end of the war. Sixteen years since then, yes, but fifteen since Marthe died. Only fifteen? I _must_ learn to think in terms of serial time again. He realized Tanzler was waiting for a response, and mustered a shrug. "Jochim! Have you been listening to me?" "Listening? Of course, Georg." "Of course!" Tanzler snorted, his moustaches fluttering. "Jochim," he said positively, "it is not as if we were young men, I admit. But life goes on, even for us old crocks." Tanzler was a good five years Kempfer's junior. "We must look ahead--we must live for a future. We cannot let ourselves sink into the past. I realize you were very fond of Marthe. Every man is fond of his wife--that goes without saying. But fifteen years, Jochim! Surely, it is proper to grieve. But to _mourn_, like this--this is not _healthy_!" One bright spark singed through the quiet barriers Professor Kempfer had thought perfect. "Were _you_ ever in a camp, Georg?" he demanded, shaking with pent-up violence. "A camp?" Tanzler was taken aback. "I? Of course not, Jochim! But--but you and Marthe were not in a real _lager_--it was just a ... a.... Well, you were under the State's protection! After all, Jochim!" Professor Kempfer said stubbornly: "But Marthe _died_. Under the State's protection." "These things _happen_, Jochim! After all, you're a reasonable man--Marthe--tuberculosis--even sulfa has its limitations--that might have happened to _anyone_!"
