Prologue

She sees herself fall in slow motion, the toe of her shoe catching on the edge of the paving-stone, her arm reaching out in front of her, her hand a pale shape like a leaf against a dark sky. The pavement swims towards her, its cracks the streets of a city seen from a skyscraper, the texture of the concrete slabs suddenly sharply in focus.

It is not a bad fall: a swelling on her left knee destined to become an outsize bramble-stain bruise, a stinging graze on the heel of her hand, a buggered pair of decent tights. Back at home, Bella balances half a bag of frozen broad beans on the knee and sips at a glass of Shiraz. She tells herself it is not a bad fall, but when she wakes the next morning it is as if a switch has been thrown, draining off all her energy in the night. She leans against the kitchen worktop to drink her coffee, not daring to sit down because she knows she will never get up again.

Overnight, London seems to have become a grotesque parody of a metropolis, no longer bustling and stimulating but loud and abrasive. Litter flies up from the gutters. Grit pricks her eyes. She feels fragile, a rabbit caught in the target-beam of headlights. Buses loom out of nowhere, bearing down on her. Cyclists swerve to avoid her, bellowing abuse. She tenses each muscle in her body when she crosses the road, imagines she can hear the thud-thudding of her heart. When someone bumps into her in the street, she thinks she will splinter into tiny fragments. In her mind, she sees her body shatter and the pieces shower through the air like the explosion of a firework, tinkling like glass as each one strikes the pavement. She imagines them coming to sweep her up so they could painstakingly reassemble her, but shards of her are left behind, unnoticed in the gutter, hidden by a litter bin or a lamp-post.

Her doctor is unsympathetic, sighing through his nostrils as she answers his questions. Months of overworking, he says. Prolonged stress. What else did she expect? Did she want to have a serious collapse? If so, she was certainly going the right way about it. No tablets, he says, no prescription. Time off. Rest. Rethink your life. That’s it? she asks. That’s it.

Her boss is unsurprised.

‘You’re no use to me half-dead,’ he says. ‘Sod off to the Caribbean for a month. Drink Mai-Tais till dawn and shag some waiters.’

The Caribbean? She is so exhausted she’d be lucky to make it down the road to the travel agent. Perhaps they could administer her Mai-Tais via a drip.

Visiting her good friends Viv and Nick in the Kentish city where they now live, she wanders at convalescent pace through the web of narrow streets, past lopsided houses and ancient flint walls. She focuses on one task at a time, as if she were a stroke victim learning afresh each skill she had previously taken for granted. Then, meandering down a quiet side street near the river, she sees the For Sale board.

Compared with the London flat she had rented with Patrick, no. 31 is a delight. Sunny. Spacious. With a proper garden rather than a sad, overshadowed strip of concrete. Yes, says Viv, a fresh start is just what Bella needs. Plenty of companies would jump at the chance to have someone with her experience.

She seems to enter a trance then, dealing with the solicitor, the building society. Writing job applications. Forms, paperwork become a welcome distraction, tangible things to focus on – things she can solve. You take a pen, fill in the spaces in neat block capitals. The questions are straightforward: Name. Address. Bank Details. Current Salary. You do it all properly and you get the result you were aiming for. It feels like magic.

She moves smoothly through the weeks on automatic pilot, gliding through her notice period at work, her smile efficiently in place, her projects on schedule. Now that she knows she is leaving, she cuts down on her hours, and fills her evening with paperwork and planning, even relishing each hitch and setback – the vendor’s pedantry about the garden shed, the surveyor’s discovery of damp – as something she can get her teeth into.

In her neat ring-binder, sectioned with coloured card dividers, she can find any particular piece of paper in an instant. The rings click closed with a satisfying clunk, containing her, keeping her life in order. She transfers her accounts, her doctor, her dentist, sends out exquisitely designed change-of-address cards. This is easy: making phone calls, folding A4 letters into three and sliding them into envelopes, measuring for curtains. And it fills her head. She needs it to hold her, as if each stage of Buying the House is a sharp staple grasping together the sections of an ancient cracked plate.
