Iteration Nine

By the ninth iteration of Tuesday the fourteenth, Daniel Mercer had stopped panicking and started doing what he was actually good at, which was taking notes. This is, he has come to believe, the single most useful fact about him, and the reason he is the person to whom this happened rather than someone else. Daniel is a statistician. He has spent his entire adult life in the company of repeated trials. A repeated trial does not frighten a statistician; a repeated trial is simply where the information lives. The first time you run an experiment you learn almost nothing. It is the repetition — the patient, identical, maddening repetition — that lets the signal climb up out of the noise and show you its face. So. The ninth Tuesday. He wakes at 6:48, two minutes before the alarm, the way he has woken eight times before. The light through the blind is the particular flat grey of a morning that has not yet decided to be anything. The radio downstairs, on its timer, is mid-sentence into the same traffic report. Daniel lies still and listens to it and confirms, word for word, that it is the same traffic report. An overturned lorry on the ring road. A delay of approximately forty minutes. The same. He gets up. He does not rush. Rushing was the second and third iterations, the bargaining ones, the ones where he believed that if he simply did the day hard enough and well enough it would agree to release him at midnight. It did not. He has retired rushing. In the kitchen he retrieves the notebook from the drawer where he leaves it — and here is the first thing worth your attention, the first genuine datum of the ninth Tuesday. The notebook should be empty. Every iteration resets. The world rewinds itself to 6:48 and the notebook rewinds with it, blank, and Daniel has accepted this; he keeps the notebook anyway because the act of writing organizes his thinking even if the writing does not survive. The notebook is not empty. On the first page, in his own handwriting, in his own careful capitals, is a single line he did not write this morning and cannot have written on any previous morning, because the notebook resets. It says: ITERATION 9. THE LOOP IS NOT PERFECT. CHECK THE CLOCK ON THE CHURCH. Daniel stands in his kitchen on the ninth identical Tuesday and reads his own handwriting telling him something he does not remember deciding, and he does the thing he is good at. He does not panic. He sits down. He turns to a clean page, and he writes the date, and the iteration number, and the time, and then he writes down, precisely, the fact that has just changed everything: *Something is persisting across the resets. Either the notebook, or me, or both. The reset is not total. There is a leak.* A leak. In eight iterations Daniel had been treating the loop as a wall — a perfect, sealed, frictionless wall, the same Tuesday stamped out again and again like coins from a die. A wall offers a prisoner nothing. But a leak. A leak is a place where something gets through, and if one thing can get through then the wall is not a wall, it is a membrane, and a membrane is a thing with properties, and properties can be measured, and a statistician with a membrane and enough trials can begin, very slowly, to map his way out. He finishes the entry. He underlines the instruction his earlier self has left him, the one he has no memory of writing and therefore must trust, because the alternative is to distrust the only version of himself who has apparently figured anything out. Then Daniel Mercer puts on his coat, on the ninth Tuesday the fourteenth, and steps out into the flat grey morning to go and look, for reasons he does not yet understand, at the clock on the church.
