What did it say? She considered tearing it open right that second, before she had time to think about it, like the way she sometimes (not very often) shoved the last biscuit or chocolate in her mouth, before her conscience had time to catch up with her greed.

The phone rang again. She wasn’t wearing her watch, and suddenly she felt like she’d lost all sense of time.

She threw the rest of the paperwork back into one of the shoeboxes and took the piece of the Berlin Wall and the letter downstairs.

As soon as she left the attic, she was picked up and swept along by the fast-running current of her life. There was a big Tupperware order to deliver, the girls to be picked up from school, the fish to be bought for tonight’s dinner (they ate a lot of fish when John-Paul was away for work because he hated it), phone calls to return. The parish priest, Father Joe, had been calling to remind her that it was Sister Ursula’s funeral tomorrow. There seemed to be some concern about numbers. She would go, of course. She left John-Paul’s mysterious letter on top of the fridge and gave Esther the piece of the Berlin Wall just before they sat down for dinner.

‘Thank you,’ Esther handled the little piece of rock with touching reverence. ‘Exactly which part of the Wall did it come from?’

‘Well, I think it was quite near Checkpoint Charlie,’ said Cecilia with jolly confidence. She had no idea.

But I can tell you that the boy with the ice cube wore a red T-shirt and white jeans and he picked up my ponytail and held it between his fingertips and said, ‘Very pretty’.

‘Is it worth any money?’ asked Polly.

‘I doubt it. How could you prove it really was from the Wall?’ asked Isabel. ‘It just looks like a piece of rock.’

‘DMA testing,’ said Polly. The child watched far too much television.

‘It’s DNA not DMA and it comes from people,’ said Esther.

‘I know that!’ Polly had arrived in the world outraged to discover that her sisters had got there before her.

‘Well then why –’

‘So who do you reckon is going to get voted off The Biggest Loser tonight?’ asked Cecilia, while simultaneously thinking, Why, yes, whoever you are who is observing my life, I am changing the subject from a fascinating period of modern history that might actually teach my children something to a trashy television show that will teach them nothing but will keep the peace and not make my head hurt. If John-Paul had been at home, she probably wouldn’t have changed the subject. She was a far better mother when she had an audience.

The girls had talked about The Biggest Loser for the rest of dinner, while Cecilia had pretended to be interested and thought about the letter sitting on top of the fridge. Once the table had been cleared and the girls were all watching TV she’d taken it down to stare at it.

Now she put down her cup of tea and held the envelope up to the light, half-laughing at herself. It looked like a handwritten letter on lined notebook paper. She couldn’t decipher a word.

Had John-Paul perhaps seen something on television about how the soldiers in Afghanistan wrote letters to their families to be sent in the event of their deaths, like messages from the grave, and had he thought that it might be nice to do something similar?

She just couldn’t imagine him sitting down to do such a thing. It was so sentimental.

Lovely though. If he died, he wanted them to know how much he loved them.

. . . in the event of my death. Why was he thinking about death? Was he sick? But this letter appeared to have been written a long time ago, and he was still alive. Besides, he’d had a check-up a few weeks ago and Dr Kluger had said he was as ‘fit as a stallion’. He’d spent the next few days tossing his head back and whinnying and neighing around the house, while Polly rode on his back swinging a tea towel around her head like a whip.

Cecilia smiled at the memory and her anxiety dissipated. So a few years ago John-Paul had done something uncharacteristically sentimental and written this letter. It was nothing to get all worked up about, and of course she shouldn’t open it just for the sake of curiosity.

She looked at the clock. Nearly eight pm. He’d be calling soon. He generally called around this time each night when he was away.

She wasn’t even going to mention the letter to him. It would embarrass him and it wasn’t really an appropriate topic of conversation for the phone.

One thing: how exactly was she meant to have found this letter if he had died? She might never have found it! Why hadn’t he given it to their solicitor, Miriam’s husband, Doug Openheimer? So difficult not to think of him in the shower every time he came to mind. Of course it had no bearing on his abilities as a lawyer, perhaps it said more about Miriam’s abilities in the bedroom. (Cecilia had a mildly competitive relationship with Miriam.)

Of course, given the current circumstances, now was not the time to be feeling smug about sex. Stop it. Do not think about the sex thing.

Anyway, it was dumb of John-Paul not to have given the letter to Doug. If he’d died she probably would have thrown out all his shoeboxes in one of her decluttering frenzies without even bothering to go through them. If he’d wanted her to find the letter it was crazy to just shove it in a random shoebox.

Why not put it in the file with the copies of their wills, life insurance and so on?

John-Paul was one of the smartest people she knew, except for when it came to the logistics of life.

‘I seriously don’t understand how men came to rule the world,’ she’d said to her sister Bridget this morning, after she’d told her about how John-Paul had lost his rental car keys in Chicago. It had driven Cecilia bananas seeing that text message from him. There was nothing she could do! He didn’t expect her to do anything, but still!
