What a Recording Cannot Be

He told nobody for twenty-six hours.

He went to work. He taught three hours of linear functions to fifteen-year-olds, invigilated a test, had lunch in the canteen with two colleagues, and at no point did he say that he had received a call from his dead wife.

He knew what would happen if he did. He had watched it happen to a colleague two years earlier: nobody disbelieves you, nobody contradicts you, people look at you differently, and three weeks later the head suggests kindly that you reduce your teaching load.

On the Wednesday evening he had done the only thing he knew how to do: he had set out the problem.

On a sheet of paper, at the kitchen table, as he would have done at the board.

Data. One incoming call, number withheld, eleventh of April, 2.17.04 a.m., duration 58 s. Twelve seconds of silence. A beep. A voice identified as É.'s. Content: do not sell the house, open the wall behind the bed.

Hypotheses. One: I am dreaming. Two: the phone is replaying an old message on its own. Three: somebody alive rang me.

He had looked at the three lines for twenty minutes and understood that there was no way of deciding between them from a kitchen. He had to go and find a fact outside.

On the Thursday at four he went into a phone shop on the avenue Bollée.

The assistant was twenty-five and wore a shirt with his name on it.

— I've got a slightly odd question.

— Go ahead.

— Can a phone play back an old voicemail by itself? A message received long ago, that would restart, say, in the night.

The assistant looked at him for a moment.

— No.

— Are you sure?

— Certain. Your voicemails sit with your operator, not in the phone. To hear them you dial a number, or you tap a button in the app. It doesn't trigger itself, and above all: it doesn't show up in your log as an incoming call from a withheld number.

— Is that important?

— It's decisive. A voicemail you listen to is an outgoing call to your mailbox. What have you got in your log?

Mathieu showed him.

Number withheld — 11 April — 02:17 — Incoming — 58 s.

— Then it's an incoming call, said the assistant. Somebody rang you. The network established a connection between another line and yours for fifty-eight seconds. That isn't a theory: that's billing. Your operator has recorded it and they can confirm it.

— And the withheld number?

— That's a service. The caller asks for their number not to be passed on. But the number exists, it's with the operator, and there are cases where it can be recovered.

— Which ones?

— The police. Or a court. Not you.

Mathieu put his phone away.

— Can I ask you something else?

— Of course.

— Can you play a recording into a telephone call?

The assistant shrugged.

— You hold a speaker up to the microphone. That's all. It's worked since 1950.

— Last question. Can a call come from an old phone? A model from the two thousands, a flip phone, with a prepaid card?

— Of course. As long as it gets 2G or 3G, it calls. We still sell them, in fact — people buy them for the mountains, for elderly parents, or to be unreachable.

— And can a prepaid card be traced?

— It's identified at purchase, in principle. What that gives you afterwards isn't my trade.

He walked home, four kilometres, as he did every evening.

What he had just obtained was considerable, and it took him an hour's walking to understand why it relieved him so much.

It was not the certainty that his wife had not come back from the dead: he had never entertained that hypothesis for a second, and would have been incapable of it — he taught proof to adolescents, he knew what evidence is and what it is not.

What relieved him was the other thing. The one he had put into words at four in the morning, alone, in a kitchen, and which had made him shake.

He had been afraid he had dreamt it.

He had been afraid, quite concretely, of becoming a man of forty-four who hears his dead wife speaking to him at night. He had read, in February, at three in the morning, everything needed to be afraid of that: the hallucinations of grief, their frequency — one person in three, the studies said — their banality, their harmlessness, and the fact that they most often concern the voice.

One person in three.

He had spent the whole of the eleventh of April with that sentence in his head, teaching linear functions.

And a twenty-five-year-old shop assistant had just explained to him, in four minutes, that an incoming call of fifty-eight seconds is a billed, traced, verifiable fact, and that no grieving brain manufactures a line in a call log.

He got home at ten past seven.

He opened his notebook and wrote, under Thursday:

Checked. Call real. Somebody alive pressed a button at 2.17 a.m.

He looked at the sentence.

Then he went up to the bedroom, put on the ceiling light, and stood in front of the upholstered headboard.

Somebody alive, who knew he was going to sell the house. Somebody alive, who knew seventeen minutes past two. Somebody alive, who possessed Élise's voice.

And somebody alive who knew what was behind that wall.
