He stepped outside and paused to take stock of the weather. Not too cold for early March, the sun peering through a gauzy layer of cloud. He pushed his hands into his coat pockets and set out. Entering the English Gardens, he followed a tree-lined path along the banks of a rain-swollen canal. He liked the park. It gave his mind a quiet place to rest after the morning's exertions on the computer. More importantly, it gave him an opportunity to see if today they were following him. He stopped walking and beat his coat pockets dramatically to indicate he had forgotten something. Then he doubled back and retraced his steps, scanning faces, checking to see if they matched any of the ones stored in the database of his prodigious memory. He paused on a humpbacked footbridge, as if admiring the rush of the water over a short fall. A drug dealer with spiders tattooed on his face offered him heroin. The professor mumbled something incoherent and walked quickly away. Two minutes later he ducked into a public telephone and pretended to place a call while carefully surveying the surroundings. He hung up the receiver.

Wiedersehen, Herr Doktorprofessor.

He turned onto the Ludwigstrasse and hurried across the university district, head down, hoping to avoid being spotted by any students or colleagues. Earlier that week, he had received a rather nasty letter from Dr. Helmut Berger, the pompous chairman of his department, wondering when the book might be finished and when he could be expected to resume his lecturing obligations. Professor Stern did not like Helmut Berger--their well-publicized feud was both personal and academic--and conveniently he had not found the time to respond.

The bustle of the Viktualienmarkt pushed thoughts of work from his mind. He moved past mounds of brightly colored fruit and vegetables, past flower stalls and open-air butchers. He picked out a few things for his supper, then crossed the street to Cafe Bar Eduscho for coffee and a Dingelbrot. Forty-five minutes later, as he set out for Schwabing, he felt refreshed, his mind light, ready for one more wrestling match with his book. His illness, as Orwell would have called it.

As he arrived at the apartment house, a gust of wind chased him into the lobby and scattered a fresh stack of salmon-colored fliers. The professor twisted his head so he could read one. A new curry takeaway had opened around the corner. He liked a good curry. He scooped up one of the fliers and stuffed it into his coat pocket.

The wind had carried a few of the leaflets toward the courtyard.

Frau Ratzinger would be furious. As he trod softly up the stairs, she poked her head from her foxhole of a flat and spotted the mess. Predictably appalled, she glared at him with inquisitor's eyes. Slipping the key into his door lock, he could hear the old woman cursing as she dealt with this latest outrage.

In the kitchen, he put away the food and brewed himself a cup of tea. Then he walked down the hallway to his study. A man was standing at his desk, casually leafing through a stack of research. He wore a white tunic, like the ones worn by the beauticians at the cosmetic and was very tall with athletic shoulders. His hair was blond and streaked with gray. Hearing the professor enter the room, the intruder looked up. His eyes were gray too, cold as a glacier.

"Open the safe, Herr Doktorprofessor."

The voice was calm, almost flirtatious. The German was accented. It wasn't Wolfie--Professor Stern was sure of that. He had a flair for languages and an ear for local dialects. The man in the tunic was Swiss, and his Schwyzerdutsch had the broad singsong accent of a man from the mountain valleys.

"Who in the hell do you think you are?"

"Open the safe," the intruder repeated as the eyes returned to the papers on the desk.

"There's nothing in the safe of any value. If it's money you're--"

Professor Stern wasn't permitted to finish the sentence. In a swift motion, the intruder reached beneath the tunic, produced a silenced handgun. The professor knew weapons as well as accents. The gun was a Russian-made Stechkin. The bullet tore through the professor's right kneecap. He fell to the floor, hands clutching the wound, blood pumping between his fingers.

"I suppose you'll just have to give me the combination now," the Swiss said calmly.

 The pain was like nothing Benjamin Stern had ever experienced. He was panting, struggling to catch his breath, his mind a maelstrom. The combination? God, but he could barely remember his name. "I'm waiting, Herr Doktorprofessor."

He forced himself to take a series of deep breaths. This supplied his brain with enough oxygen to permit him to access the combination to the safe. He recited the numbers, his jaw trembling with shock. The intruder knelt in front of the safe and deftly worked the tumbler. A moment later, the door swung open. The intruder looked inside, then at the professor. "You have backup disks. Where do you keep them?" "I don't know what you're talking about." "As it stands right now, you'll be able to walk with the use of a cane." He raised the gun. "If I shoot you in the other knee, you'll spend the rest of your life on crutches."

The professor was slipping from consciousness. His jaw was trembling. Don't shiver, damn you! Don't give him the pleasure of seeing your fear!

"In the refrigerator." "The refrigerator?"

"In case"--a burst of pain shot through him--"of a fire." The intruder raised an eyebrow. Clever boy. He'd brought a bag along with him, a black nylon duffel, about three feet in length. He reached inside and withdrew a cylindrical object: a can of spray paint. He removed the cap, and with a skilled hand he began to paint symbols on the wall of the study. Symbols of violence. Symbols of hate. Ludicrously, the professor found himself wondering what Frau Ratzinger would say when she saw this. In his delirium, he must have murmured something aloud, because the intruder paused for a moment to examine him with a vacant stare.

When he was finished with his graffiti, the intruder returned the spray can to his duffel, then stood over the professor. The pain from the shattered bones was making Benjamin Stern hot with fever. Blackness was closing in at the edges of his vision, so that the intruder seemed to be standing at the end of a tunnel. The professor searched the ashen eyes for some sign of lunacy, but he found nothing at all but cool intelligence. This man was no racist fanatic, he thought. He was a professional.

The intruder stooped over him. "Would you like to make a last confession, Professor Stern?"

"What are you"--he grimaced in pain--"talking about?"

"It's very simple. Do you wish to confess your sins?"

"You're the murderer," Benjamin Stern said deliriously.

The assassin smiled. The gun swung up again, and he fired two shots into the professor's chest. Benjamin Stern felt his body convulse but was spared further pain. He remained conscious for a few seconds, long enough to see his killer kneel down at his side and to feel the cool touch of his thumb against his damp forehead. He was mumbling something. Latin? Yes, the professor was certain of it.

"Ego te absolvo a peccatis tuis, in nomine Patris et Filii et Spiritus Sancti. Amen."

The professor looked into his killer's eyes. "But I'm a Jew," he murmured.

"It doesn't matter," the assassin said.

Then he placed the Stechkin against the side of Benjamin Stern's head and fired one last shot.
