“If it were that simple,” Rita says, insulted, “why didn’t you explain it to the public prosecutor yourself?”
A fat woman with dyed red hair and plucked eyebrows approaches in her apron and puts a cup down on the table.
“It’s normally self-service here,” she says.
“Because it’s your case after all, Rita, my child,” Schilf says. “Excellent work. You’ll be police chief in no time.”
He puts twice the required amount into the serving woman’s outstretched hand and looks away to avoid her death stare. The coffee is surprisingly good. It’s a good day all in all. The detective is doing the right thing and getting what he wants.
“Toady,” Rita says. “Of course it’s my case. And it’s the last one that you’ll be interfering with.”
“Believe me, I’ve only been sent in the name of God. You’ll never have the misfortune of accepting my help again.”
“Glad to hear it.”
The detective thinks he would like to bottle a few of Rita’s snorts to tide him over in bad times.
“Now hand the guy over,” she says.
“How do you know it’s a man?”
“Women don’t decapitate their victims.”
“The New Testament would have it otherwise.”
“Wrong, Schilf. Salome asked for John the Baptist to be beheaded. That was secondary liability at best, or just incitement.”
“You know your Bible,” Schilf says in acknowledgment, “and the basics of German criminal law. What would happen if Salome had blackmailed the murderer into doing the deed, though?”
“This isn’t a seminar on criminal law!” Rita growls.
“Coercion,” Schilf says. “Extenuating circumstances according to the prevailing view?”
“Who … is.… it?”
With every word, Schilf thinks he hears Rita chopping the air with the side of her hand. Rita had been an astonishingly good shot during her training. You could tell from her hand, the detective thinks. He would quite happily stand in front of her while, feet shoulder-width apart, arms outstretched, she aimed a Walther PPK at him. The bullet would bore a hole in his forehead, pierce through the bird’s egg in his frontal lobe, and drill painlessly into his brain. Schilf sees himself falling to his knees and collapsing onto his side, as he has observed other men doing a few times over the course of his career. Set free by Rita’s hand, he would fly out through the hole in his forehead and finally mesh with the network of the universe, where there is no time and space, and would enter the state popularly known as “the past.”
What a lovely dream, the detective thinks.
“The physicist,” he says. “The one with the kidnapped son.”
He lights a cigarillo and enjoys the first puffs in total peace. Not even the sound of breathing comes from the telephone.
“Good,” Rita finally says. Her voice is businesslike, if a little husky. “I thank you.”
“Wait.” Schilf takes the cigarillo out of his mouth and bends forward, as if Rita were sitting on the other side of the table. “He was blackmailed.”
“At least,” Rita says slowly, “the case seems to have nothing to do with the hospital scandal.”
“You don’t know that yet,” the detective superintendent says sharply. “Were you listening to me? I said: Sebastian was blackmailed.”
“The police chief will cry with joy.”
“Rita!” The detective barely notices that the woman in the apron is beside him again. “Have you asked yourself why I’m telling you who it is? So that the case won’t be taken away from you! You’re the one with the most sense in that whole pigsty. Don’t tell me that I’ve been mistaken!”
“All right, Schilf.”
“The man is innocent,” the detective says.
“Surely. The main thing is, there’s no connection to the hospital scandal.”
The conversation is over. The line is dead.
“You’re not allowed to smoke here,” the woman in the apron says.
“Damn,” Schilf says.
“Absolutely no smoking here.”
The detective looks into her doughy face and flashes his police ID at her.
“Another espresso,” he says.
As the fat woman waddles hastily back to the counter, he drops his head into his hands. It’s practically impossible, inconceivable that he has just made a serious mistake. He is holding the cigarillo between his thumb and his index finger, and ash falls past his right temple onto the table. There is the smell of singed hair.

THERE IT IS AGAIN, THE DOUGHY FACE. Plucked eyebrows and dyed red hair in the shape of a cloud. This time the woman is a kind of librarian who is looking at the detective in an unfriendly manner. Her fleshy fingers are tapping away continuously with great precision on a computer keyboard. The familiar pounding has started behind Schilf’s temples.
“What do you want?”
It is not easy to answer this question. Schilf probably wants a new Rita Skura, one who is not thinking of her own career or of the walrus-mustached police chief, but only of how she can help the first chief detective superintendent in his mission for truth and justice. And he wants a slim librarian with hair that has been combed back, and a large room whose walls are lined with shelves of oak that go right up to the ceiling. He wants absentminded scientists who climb ladders to reach the volumes on the very top shelves. He wants green lampshades on antique desks.
Schilf is nauseated by the smell of the freshly cleaned carpet underfoot. Metal shelving divides the room into cells containing dark computer monitors. He is the only visitor. The conversation with Rita feels like rheumatism in his bones. He longs for a living being, for understanding and support, or perhaps just for the warmth of a freshly run bath.
“What do you want?” The librarian repeats herself slowly and clearly. She probably has to deal with confused foreign researchers quite often.
“Quantum physics,” the detective says.
The woman’s face shakes with silent laughter, and Schilf realizes that he has made a joke. He does not join in.
“Go ahead,” she says.
Schilf does not bother with the rows of books whose covers threaten investigations of the cosmological lambda term or the missing-mass problem. He sits down at one of the computers and types Sebastian’s name into the catalogue search function. The list is long. Schilf chooses two publications whose titles contain more familiar than unfamiliar words. He writes down the classification codes on a piece of paper and walks back to the desk. The librarian perches a pair of spectacles on her wide face and waddles over to a shelf of journals. The prim design of the booklets she pulls out would warn off any normal person from trying to read them. The librarian pats him encouragingly on the shoulder as she hands them over, and Schilf is left with his booty.
“Everett’s Many-Worlds Interpretation as the Foundation for Quantum Cosmology.”
“The Fluctuating Scalar Field, i.e.: The Eternal Return of the Same.”
Schilf makes a concerted effort not to wonder about the sense of this undertaking and whispers encouraging words to himself: Let’s just see, piece of cake, this. He starts reading the first article.
Since his phone call with Rita, he has been plagued by the feeling that he has no time left, and that whatever he does, he is neglecting something else far more important. His method does not work in such a situation. In order to look through things, to lurk and listen and wait for something to rise from the cellar of reality to the surface, he needs one thing above all: inner peace. Now he can only struggle to understand things with the usual tools of the trade, which will bring an average rate of success at best. His startled brain races along the words stretching across the pages like worms, staggers then falls, catches itself in the barbs of a semicomprehensible sentence (“Applied to the cosmos, the quantization machine leads to an assumption of general wave function”), and slides across the slippery ground of the next clause. It stumbles over a familiar phrase (
“everything is possible and happens somewhere”) and ends up standing in front of the impenetrable wall of string theory and supersymmetry.
Schilf does not understand a word. He does not have the faintest idea what Sebastian is writing about. The pounding of his headache has turned into hammering. He puts the journal aside and rouses the computer. On the home page of the search engine he discovers a report on the re-arrest of the former chess world champion Kasparov. He feels a little better after reading this short article without any trouble. Filled with hope, he types Sebastian’s name into the gateway to the virtual world.
Two photographs immediately pop up under the heading Circumpolar. There is Sebastian’s boyish, laughing face, next to a striking man whom Schilf would have immediately cast as Mephisto if he were directing a film of Faust. The detective looks at the two men for a long time: the laughter and the silence, the wanting and the waiting, the white king and the black king. A two-headed oracle, the detective thinks. It is some time before he realizes what the Web page is actually offering. You can download an episode of the science program Circumpolar, subtitled “The Clash of the Physicists.” Schilf pulls his chair closer to the screen and clicks on “Watch Now.”
Sebastian and Oskar are seated on protruding chairs in the narrow prison of a small screen. The show’s host is sitting between them in a deliberately casual manner, leaning forward with his elbows on his knees as he introduces the program.
Twenty-first century. Challenges that no one had ever expected. The intersection between science and philosophy.
If the host had been alone onstage, he would have looked like everyone’s picture of the kindly professor: spectacles, beard, and uncut hair. Next to his lofty guests, he simply looks untidy. Oskar lets an arm dangle over his chair’s armrest, and examines the polished tips of his shoes. On the other side, Sebastian is looking straight into the camera with a defiant expression, and he winces when it is his turn to speak. He twists the microphone in his hands for such a long time that the detective feels nervous watching him. Finally, without any preamble whatsoever, Sebastian begins to speak.
“The parallel universe theory rests upon an interpretation of quantum mechanics, according to which a system assumes all circumstances that are possible within the specific probabilities. The elementary particles are the basic building blocks of our world. Their existence determines our existence. That can mean that we and everything visible around us are adopting all states at every moment.”
By his sharp intake of breath while lifting the microphone gently, the host signals that more than three long sentences in a row are unthinkable even for the audience of a public broadcasting station. Sebastian refuses to be thrown off track. The detective nods at him across everything that separates them.
“We can imagine it visually,” Sebastian says. “There is a universe in which Kennedy did not travel to Dallas on that fateful day, and was not shot. And one in which I didn’t have cheesecake on my birthday but chocolate cake.”
There is the sound of grateful laughter in the studio. Only now does the camera swing around to show that the three men on the stage are not alone in the room. The detective realizes that “LIVE” is displayed in tiny letters in a corner of the screen. Transfixed by the notion that the Sebastian onscreen has no idea yet of the reversal of fortune that awaits him, Schilf misses the next few phrases and just catches Sebastian gesturing with his hand that he will stop after his next sentence.
“Everything that is possible happens.”
The audience claps. Sebastian’s fervor makes his statement sound like a promise of salvation. Even the host pretends to clap as he asks Oskar to give his opinion. Oskar has listened to Sebastian with a smile on his face, more amused than mocking, as if he is a grown-up listening to a precocious child.
“What Sebastian has described,” he says, holding the microphone very close to his mouth, in a voice that makes the detective shudder, “is a cozy attempt to circumnavigate God.”
There are murmurs and subdued laughs. Sebastian looks offstage, as if the whole thing suddenly has nothing to do with him.
“You’ll have to explain that,” the host says, when Oskar does not continue.
“It’s quite simple.”
In the dead silence of the studio, Oskar takes a sip of water. It is clear that he is in control of the situation on the stage.
“According to the Many-Worlds Interpretation, a creator never need make a decision. We exist simply because everything that is at all possible exists somewhere.”
Ever since his conversation with Sebastian, the detective has been working on a formulation that he himself does not fully understand: The world is the way it is because there are observers to watch it existing.
Schilf regrets that television programs don’t permit interruptions.
“That is a cheap response to a question of metaphysics,” Oskar says. “Totally unusable as a scientific viewpoint.”
“Why unusable?” the host asks, raising a hand to shush another murmur rising in the audience.
“Because other universes avoid experimental examination.”
Oskar leans back as if he has had the last word for the evening. In the same instant Sebastian bends forward and speaks into the microphone.
“That’s how it is in theoretical physics,” he says. “Even Einstein’s ideas were partly worked out on paper to begin with, and then proven later in experiments.”
“In the words of Einstein himself,” Oskar replies calmly, “‘Only two things are infinite, the universe and human stupidity, and I’m not sure about the universe.’”
“What I’m talking about here,” Sebastian says, “has been described by many reputable physicists: Stephen Hawking, David Deutsch, Dieter Zeh.”
“Then Hawking, Deutsch, and Zeh have just as little an idea of physics,” Oskar says.
As the audience protests, a close-up of Oskar’s laughing face is shown. The arrogant expression has disappeared and he looks like a schoolboy who is delighting in pulling off a successful prank. The camera turns to Sebastian, who is shaking his head and lifting a finger to show that he has something to say. Schilf leans forward so that his nose is practically touching the monitor. Don’t let yourself be wound up by him. Don’t defend anything that you don’t believe in. Tell them that there is no time and space. That Many Worlds and one world are all the same, even if matter is nothing more than an idea in the observer’s thoughts.
The host calls for silence so that Sebastian can speak.
“The discussion here doesn’t seem to be about the intersection between physics and philosophy,” Sebastian says, “but about the intersection between physics and polemic.”
Laughter from the audience shows that they are on his side again.
“Much as barbed language can be fun—”
“By the way,” Oskar interrupts, placing a finger on his cheek as if something has just occurred to him, “according to your theory, it is not just the Creator who does not have to make any decisions. Nobody else does, either.”
“On the contrary,” Sebastian says. “One of the philosophical advantages of the Many-Worlds Interpretation is that it can explain the free will of mankind. In linear time—”
“Now it’s getting esoteric!” Oskar laughs.
The camera is too late to catch Oskar, reaching him only as he waves away the host’s admonishment. Schilf, who is watching the screen so intently that his eyes are burning, notices that Oskar’s left foot is twitching.
“In linear time,” Sebastian says, “our fates are determined from the earliest past into the most distant future. Our decisions are nothing more than biochemical processes in the brain that are subject to the laws of cause and effect.” He leaves a dramatic pause before continuing. “Now imagine that every conceivable causal sequence exists at the same time in parallel universes. The way every individual universe develops may be predetermined, but our freedom consists of being able to choose one of these many worlds with every decision.”
“Ladies and gentlemen, justification for the freedom of will through physics,” the host says exultantly. His glasses reflect the spotlights, and he looks incredibly happy, as if he can see his program director’s beaming face as he speaks.
“And that holds true, although science and determinism normally—”
“Then I would like to know,” Oskar interrupts, “why we can’t simply exercise an act of will to choose a universe in which the Second World War never happened. That would be nice.”
The blood has risen in Sebastian’s face. He slides forward and sits upright.
“That’s because we are subject to the principle of self-consistency,” he says. “And you know that only too well! Otherwise, according to the second law of thermodynamics, we could dissolve into a state of cumulative chaos.”
“And that’s exactly what we’re doing,” Oskar says. “Looking at you, one might conclude that this dissolution can sometimes happen all too quickly.”
He gives Sebastian a challenging look and taps his finger on his forehead.
“Excuse me,” the host says, “we can’t …”
The uproar in the studio drowns him out. Oskar makes an impatient gesture with his hand to wave away any further disturbance, and turns his perfect profile to the camera, looking past the host, straight at Sebastian. The twitch in his left foot has grown more violent. His relaxed manner suddenly seems a poor front. He looks like a man whose smooth facade conceals boundless rage.
“If every decision is accompanied by its opposite,” he says, “then it is no decision at all. Do you know what your justification for free will is? It’s a license to behave like a swine!”
“Please …” the host says.
“That’s …” Sebastian attempts.
“One universe,” Oskar says. “With no possibility for escape. That’s what you should be researching. That’s where you should be living. And where you should take responsibility for your own decisions.”
“That’s not a scientific argument,” Sebastian says, barely managing to control himself. “That’s moralistic dogmatism!”
