THE APARTMENT HOUSE at Adalbertstrasse 68 was one of the few in the fashionable district of Schwabing yet to be overrun by Munich's noisy and growing professional elite. Wedged between two red brick buildings that exuded prewar charm, No. 68 seemed rather like an ugly younger stepsister. Her facade was a cracked beige stucco, her form squat and graceless. As a result her suitors were a tenuous community of students, artists, anarchists, and unrepentant punk rockers, all presided over by an authoritarian caretaker named Frau Ratzinger, who, it was rumored, had been living in the original apartment house at No. 68 when it was leveled by an Allied bomb. Neighborhood activists derided the building as an eyesore in need of gentrification. Defenders said it exemplified the very sort of Bohemian arrogance that had once made Schwabing the Montmartre of Germany--the Schwabing of Hesse and Mann and Lenin. And Adolf Hitler, the professor working in the  second-floor window might have been tempted to add, but few in the old neighborhood liked to be reminded of the fact that the young Austrian outcast had once found inspiration in these quiet tree-lined streets too.

To his students and colleagues, he was Herr Doktorprofessor Stern. To friends in the neighborhood he was just Benjamin; to the occasional visitor from home, he was Binyamin. In an anonymous stone-and-glass office complex in the north of Tel Aviv, where a file of his youthful exploits still resided despite his pleas to have it burned, he would always be known as Beni, youngest of Ari Shamron's wayward sons. Officially, Benjamin Stern remained a member of the faculty at Hebrew University in Jerusalem, though for the past four years he had served as visiting professor of European studies at Munich's prestigious Ludwig-Maximilian University. It had become something of a permanent loan, which was fine with Professor Stern. In an odd twist of historical fate, life was more pleasant for a Jew these days in Germany than in Jerusalem or Tel Aviv.

The fact that his mother had survived the horrors of the Riga ghetto gave Professor Stern a certain dubious standing among the other tenants of No. 68. He was a curiosity. He was their conscience. They railed at him about the plight of the Palestinians. They gently asked him questions they dared not put to their parents and grandparents. He was their guidance counselor and trusted sage. They came to him for advice on their studies. They poured out their heart to him when they'd been dumped by a lover. They raided his fridge when they were hungry and pillaged his wallet when they were broke. Most importantly, he served as tenant spokesman in all disputes involving the dreaded Frau Ratzinger. Professor Stern was the only one in the building who did not fear her. They seemed to have a special relationship. A kinship. "It's

Stockholm Syndrome," claimed Alex, a psychology student who lived on the top floor. "Prisoner and camp guard. Master and servant." But it was more than that. The professor and the old woman seemed to speak the same language.

The previous year, when his book on the Wannsee Conference had become an international bestseller, Professor Stern had flirted with the idea of moving to a more stylish building--perhaps one with proper security and a view of the English Gardens. A place where the other tenants didn't treat his flat as if it were an annex to their own. This had incited panic among the others. One evening they came to him en masse and petitioned him to stay. Promises were made. They would not steal his food, nor would they ask for loans when there was no hope of repayment. They would be more respectful of his need for quiet. They would come to him for advice only when it was absolutely necessary. The professor acquiesced, but within a month his flat was once again the de facto common room of Adalbertstrasse 68. Secretly, he was glad they were back. The rebellious children of No. 68 were the only family Benjamin Stern had left.

The clatter of a passing streetcar broke his concentration. He looked up in time to see it disappear behind the canopy of a chestnut tree, then glanced at his watch. Eleven-thirty. He'd been at it since five that morning. He removed his glasses and spent a long moment rubbing his eyes. What was it Orwell had said about writing a book? A horrible, exhausting struggle, life a long bout of some painful illness. Sometimes, Benjamin Stern felt as though this book might be fatal.

The red light on his telephone answering machine was blinking. He made a habit of muting the ringers to avoid unwanted interruptions. Hesitantly, like a bomb handler deciding which wire to cut, he reached out and pressed the button. The little speaker emitted a blast of heavy metal music, followed by a warlike yelp.

"I have some good news, Herr Doktorprofessor. By the end of the day, there will be one less filthy Jew on the planet! Wiedersehen, Herr Doktorprofessor." click.

Professor Stern erased the message. He was used to them by now. He received two a week these days; sometimes more, depending on whether he had made an appearance on television or taken part in some public debate. He knew them by voice; assigned each a trivial, unthreatening nickname to lessen their impact on his nerves. This fellow called at least twice each month. Professor Stern had dubbed him Wolfie. Sometimes he told the police. Most of the time he didn't bother. There was nothing they could do anyway.

He locked his manuscript and notes in the floor safe tucked beneath his desk. Then he pulled on a pair of shoes and a woolen jacket and collected the rubbish bag from the kitchen. The old building had no elevator, which meant he had to walk down two flights of stairs to reach the ground floor. As he entered the lobby, a chemical stench greeted him. The building was home to a small but thriving cosmetic. The professor detested the beauty shop. When it was busy, the rancid smell of nail-polish remover rose through the ventilation system and enveloped his flat. It also made the building less secure than he would have preferred. Because the cosmetic had no separate street entrance, the lobby was constantly cluttered with beautiful Schwabinians arriving for their pedicures, facials, and waxings.

He turned right, toward a doorway that gave onto the tiny courtyard, and hesitated in the threshold, checking to see if the cats were about. Last night he'd been awakened at midnight by a skirmish over some morsel of garbage. There were no cats this morning, only a pair of bored beauticians in spotless white tunics smoking cigarettes against the wall. He padded across the sooty bricks and tossed his bag into the bin.

Returning to the entrance hall, he found Frau Ratzinger punishing the linoleum floor with a worn straw broom. "Good morning, Herr Doktorprofessor," the old woman snapped; then she added accusingly: "Going out for your morning coffee?"

Professor Stern nodded and murmured, "ja ja," Frau Ratzinger." She glared at two messy stacks of fliers, one advertising a free concert in the park, the other a holistic massage clinic on the Schelling-strasse. "No matter how many times I ask them not to leave these things here, they do it anyway. It's that drama student in 4B. He lets anyone into the building."

The professor shrugged his shoulders, as if mystified by the lawless ways of the young, and smiled kindly at the old woman. Frau Ratzinger picked up the fliers and marched them into the courtyard. A moment later, he could hear her berating the beauticians for tossing their cigarette butts on the ground.
