"You'll need salt," says Ewan, right in her ear. The first time he spoke to her it startled and even alarmed her--Ewan having been no longer in a tangibly living condition for at least four days--but now she's more relaxed about him, unpredictable though he is. It's wonderful to hear his voice, even if she can't depend on having any sort of a conversation with him. His interventions tend to be one-sided: if she answers him, he doesn't often answer back. But it was always more or less like that between them.

She hadn't known what to do with his clothes, afterwards. At first she left them hanging in the closet, but it was too upsetting to open the door and see the jackets and suits ranged on their hangers, waiting mutely for Ewan's body to be slipped inside them so they could be taken for a walk. The tweeds, the woollen sweaters, the plaid work shirts?.?.?.?She couldn't give them away to the poor, which would have been the sensible thing. She couldn't throw them out: that would have been not only wasteful but too abrupt, like ripping off a bandage. So she'd folded them up and stored them away in a trunk on the third floor, with mothballs.

That's fine in the daytimes. Ewan doesn't seem to mind, and his voice, when it turns up, is firm and cheerful. A striding voice, showing the way. An extended index-finger voice, pointing. Go here, buy this, do that! A slightly mocking voice, teasing, making light: that was often his manner towards her before he became ill.

At night, however, things get more complex. There have been bad dreams: sobbing from inside the trunk, mournful complaints, pleas to be let out. Strange men appearing at the front door who hold out promises of being Ewan, but who are not. Instead they're menacing, with black trench coats. They demand some garbled thing that Constance can't make out, or, worse, they insist on seeing Ewan, shouldering their way past her, their intentions clearly murderous. "Ewan's not home," she'll plead, despite the muted cries for help coming from the trunk on the third floor. As they begin to tromple up the stairs, she wakes up.

She's considered sleeping pills, though she knows they're addictive and lead to insomnia. Maybe she ought to sell the house and move to a condo. That notion was being pushed at the time of the funeral by the boys, who are not boys any more and who live in cities in New Zealand and France, too conveniently far for them to visit her much. They'd been backed up in spades by their brisk but tactful and professionally accomplished wives, the plastic surgeon and the chartered accountant, so it was four against one. But Constance stood firm. She can't abandon the house, because Ewan is in it. Though she'd been smart enough not to tell them about that. They've always thought she was slightly borderline anyway because of Alphinland, though once such an enterprise makes a lot of money the whiff of nuttiness around it tends to evaporate.

Condo is a euphemism for retirement home. Constance doesn't hold it against them: they want what is best for her, not merely what is simplest for them, and they were understandably perturbed by the disorder they'd witnessed, both in Constance--though they'd made allowances because she was in the throes of mourning--and in, just for example, her refrigerator. There were items in that refrigerator for which there was no sane explanation. What a swamp, she could hear them thinking. Awash in botulism, a wonder she hasn't made herself seriously ill. But of course she hadn't, because she wasn't eating much in those final days. Soda crackers, cheese slices, peanut butter straight from the jar.

The wives had dealt with the situation in the kindest way. "Do you want this? What about this?" "No, no," Constance had wailed. "I don't want any of it! Throw it all out!" The three little grandchildren, two girls and a boy, had been sent on a sort of Easter egg hunt, searching for the half-drunk cups of tea and cocoa that Constance had left here and there around the house and that were now covered with grey or pale-green skins in various stages of growth. "Look, Maman! I found another one!" "Ew, that's gross!" "Where is Grandpa?"
