Rule Four

He was in the car park at twenty past, walking the perimeter with a coffee, and she watched him from the window for about ninety seconds before she went down, which she has never admitted to him and which is in this account because she told her sister.

The morning was clear and already warm, which was the thing she had been worrying about at one in the morning, and Osgur the night manager had left a note on the fridge door for the day staff in four languages, and had also, without being asked, put a probe thermometer in with the boxes and written the overnight low and high on the note in pencil.

Four hundred and ninety-four kilometres to Ardsmuir. Five hours and ten minutes without stops, six with. It was Friday. The wedding was Saturday at two and the assembly needed six hours and she had allowed herself Friday evening and Saturday morning, and as of half past seven on Friday morning that plan was, for the first time since Vellhaven, comfortable.

They got on the road at ten to eight. He drove. She fell asleep at about kilometre six hundred and eighty, entirely without meaning to, and woke at kilometre eight hundred and one with her head against the window and a jacket over her that was not hers, and lay still for a minute working out what to do about that and then decided to do nothing about it at all.

"You have been asleep for an hour and a half," he said, without looking over. "There is a coffee in the holder and it is cold, and I did not want to wake you, and I have been driving at exactly the speed limit for ninety minutes like a man transporting a cake."

Kiki sat up and looked at the boxes and then at the temperature reading on the dash and then at him, and said, "You have got the air conditioning at eighteen." "Yes." "For an hour and a half." "It is a nine-kilo cake and you told me twenty degrees at Vellhaven," said Raff Oduya-Kine, "and I have been extremely cold since about kilometre seven hundred, and I would like that noted."

She has said that this is the moment. Not the bridge, not the fridge, not any of the four times either of them broke rule four. A man who had been cold for a hundred kilometres rather than adjust a dial and risk a hundred and forty sugar freesias, and who mentioned it only as a joke, at kilometre eight hundred and one, on a Friday morning.

He broke it himself at kilometre nine hundred and forty, on a straight stretch of dual carriageway with nothing in front of them, and he did it the way people do, which is in the middle of talking about something else entirely.

They had been discussing whether it is possible to make a decent loaf in a domestic oven, on which Kiki has views. And Raff said, "My father would have argued with you about that for an hour and then agreed with you and denied that he had ever thought otherwise," and then he was quiet for about four seconds and then he said, "He is at Ardsmuir Royal. He has been since the twelfth. That is why I am going."

Kiki did not say sorry. She has been asked about that too, and what she says is that she has been on the receiving end of a great many sorrys and that none of them ever helped, and that she asked the only question she could think of that treated him as a person rather than a situation, which was: "Is he still himself?"

Raff had to pull into the inside lane for a moment. Then he said, "Yes. Completely. That is the whole problem. He is entirely himself and he has about a week and he knows it, and he has spent four days being extremely funny about it to my sisters and I cannot bear it."

She let him drive for a bit. Then she said, "Why were you at Vellhaven?" And he said that he had gone home. On Tuesday, after four days in the corridor, he had gone home for a night to get clean clothes and a document his father wanted, and the document is what was in the soft bag, and the weather had shut the airport, and the four o'clock had been the last thing he could get.

"What document?" "His teaching certificate." Raff said it without inflection. "From 1978. He wants to give it to the hospice chaplain, who plays, and who has been sitting with him in the evenings, and who mentioned on Sunday that she never got past grade six. He has been on at me about it since Monday." He indicated, moved out, moved back. "It is in a bag in the boot of a hire car in a service station car park at kilometre nine hundred and forty, and I am going to hand a dying man a piece of card from 1978, and it is the last thing he is ever going to ask me for."

Kiki Balogun-Ward, who had spent thirty hours protecting nine kilos of flour and sugar with the ferocity of a woman guarding a child, looked at the boot in the mirror and said, "Then we are both carrying something, and mine is heavier and yours matters more, and we have got a hundred and sixty kilometres left. Do you want me to drive?" And he said yes.

She drove them into Ardsmuir at ten past two on the Friday afternoon and the whole of the last hundred and sixty kilometres was, by both accounts, the easiest part of the entire journey.

He talked. Not about the hospital: about his father, which is a different thing and which nobody in four days had let him do, because everybody around him was managing his grief and nobody had simply asked him what the man was like.

Kiki asked what he was like. She asked it at kilometre nine hundred and sixty and she got a hundred and forty kilometres of answer: a piano tuner from a town of four thousand people who had tuned in eleven schools and three churches and one concert hall, who could not read music at speed and had never admitted it, who had a rule that you never told a customer their instrument was beyond saving on a first visit because people cry, who had taught his son to hear a fifth at the age of six and had never once suggested he should do it for a living.

"What do you do?" said Kiki, at about kilometre ten fifty, and it was the first time in twenty-three hours that either of them had asked the other that question, which she pointed out, and which he had also noticed.

"I am an acoustician," said Raff. "I do rooms. Concert halls, mostly, and about four schools a year because it is the only part that is worth anything." He looked out at the outskirts of Ardsmuir coming up. "He thinks it is the same job. He has told everybody in that hospice that his son does the same job he does, but bigger, and he is not entirely wrong and I have stopped correcting him."

They came off at junction four. Ardsmuir Royal is signed from the roundabout, and the hotel where a hundred and forty people were arriving the following morning is signed from the same roundabout in the other direction, and Kiki put the indicator on for the hospital without any discussion at all.

"You have got a cake," Raff said. And Kiki said, "I have got a cake and twenty-four hours and a walk-in fridge that I rang about from a hotel car park at seven this morning, and you have got a piece of card from 1978. Do not be an idiot at kilometre eleven hundred."

She dropped him at the door. He got the soft bag out of the boot, and stood there for a second with it, and then leaned back in through the passenger window.

What he said was: "I do not know how long I am going to be." And Kiki said, "I know. That is not a thing you can know." And he said, "I meant that I do not know how to end this conversation, and I have been thinking about it since the roundabout, and I have got nothing."

She wrote her number on the back of the hire agreement, under the four rules, and tore that bit off and gave it to him, and said, "There. Now you do not have to end it. Go on."

He went in. She sat in the car park for about four minutes with the engine off and then drove to the hotel and checked in and spent the next six hours in a kitchen with a pastry chef called Ines who had been told about her by a night manager four hundred and ninety kilometres away, because Osgur had rung ahead on Friday morning without mentioning it to anybody, which Kiki did not find out about until the following spring.

The assembly took five hours and forty minutes rather than six. The freesias had lost four, which is well inside what you allow. The tiers were level, the sugar work had held, the temperature log from the boot of a hire car and a hotel walk-in and a second hotel walk-in read a maximum of nineteen point one, and at eleven o'clock on Friday night Nkechi Balogun-Ward stood in a hotel kitchen in Ardsmuir and looked at a finished wedding cake and cried for about ninety seconds and then went to bed.

Her phone had one message on it. It had arrived at twenty to nine and it said: He is asleep. He was awake for two hours and I gave him the card and he made me read out the examiner's name because he could not see it, and then he told me the man was a fraud who could not hear a wolf fifth in a phone box. My sisters are here. Thank you for the hundred and sixty kilometres. R.

She read it four times. Then she wrote back: The cake is finished and it is the best thing I have ever made. There will be a hundred and forty people in a room tomorrow at two and about a hundred and thirty-eight of them will be my relatives. If you want somewhere to be at any point in the next four days, there is a place at table nine and nobody will ask you a single question. K.

He did not reply that night. She had not expected him to.
