"I expected more of a missionary's son."

The Dean's parting words still nagged at Timothy as he stepped off the train. He crossed the platform, pushed his way into the little station, and looked around the waiting room for a familiar face. But all he saw were strangers, so he dropped his bags on the floor and slumped onto one of the benches.

Suspended from school for two weeks – that much he'd expected, even counted on. And of course he'd known the Dean would give him a lecture beforehand, full of mournful reproaches like You were such a fine student and Why did you do it, Sinclair?

But bringing his parents into it ... that was low. Timothy swiped the dark wing of hair away from his eyes and sank down in his seat, scowling.

A woman in a long winter coat swished past, and the guitar case he'd propped against the wall began to topple. Hastily he grabbed the instrument and steadied it. Then his eyes fell to the sticker pasted on the lid: GREENHILL CHRISTIAN BOYS' SCHOOL, EST. 1956. LET YOUR LIGHT SO SHINE BEFORE MEN.

With sudden savagery Timothy dug a thumbnail under the sticker and began ripping it off piece by piece, until nothing remained but a gummy wad of paper in his hand. He shook it off into the nearby bin and slouched down again.

Minutes ticked by as he sat: five, ten, twenty. All the while people marched in and out of the station, most of them white-skinned and thin-lipped and walking as though they were in a hurry. Timothy studied their faces as they passed, but none looked familiar. Had his cousin forgotten him?

An icy gust swirled through the open door, and Timothy pulled his jacket closer. Six months in this country, and he hadn't got used to the cold. He might look like an English boy, but he still felt Ugandan inside ...

"There you are!"

He started and looked around to see Peri, his cousin's wife, striding towards him.

"You've grown," she remarked, scooping his rucksack from the floor and slinging it over her shoulder before bending to pick up Timothy's suitcase as well. "I almost didn't recognize you. Nice lip, by the way," and with that she headed for the door, her long legs carrying her down the steps with ease.

Was it that obvious? Timothy touched his swollen mouth and winced. He grabbed his guitar and hurried out after Peri, arriving at the car park to see her fling open the back door of a small red car and toss the suitcase inside as though it weighed nothing whatsoever.

"Get in," she said.

Was she angry with him, or just being her usual no-nonsense self? It was probably better not to ask. Timothy slid his guitar onto the back seat and climbed in.

As they drove away from the station, Timothy watched Peri closely. On the surface she looked much the same as she had on his last visit three years ago: still lean as a cheetah, with hair as pale as her eyes were dark and an unconventional, almost feral beauty. But there was no expression in her features, and she kept her gaze fixed on the road, not even glancing at him.

"So tell me," she said as she swung the car into a roundabout. "What brings you here? I thought Paul's parents were supposed to look after you if anything happened."

"They are," said Timothy, "but they've gone to Majorca. They won't be back until the end of the month."

"I see. So Paul's agreed to take you for – what? Two weeks?"

"Three, actually," said Timothy. "I've got half-term right after the suspension."

"What's that?"

"There's a week of holidays after ..." he began in a louder voice, but she cut him off.

"I'm not deaf. I'm asking, what's a suspension?"

For an intelligent woman, Peri had some surprising gaps in her knowledge. "I got sent away from school," he said. "For hitting another boy."

Her brows flicked upwards. "That's an odd sort of punishment."

"Not really," said Timothy, thinking of the schoolbooks stuffed into his rucksack. Not to mention the thousand-word essay on the Beatitudes the Dean had assigned him as penance. Blessed are the peacemakers ...

"Did he deserve it? The boy you hit?"

Timothy shifted in his seat. "Sort of. Not really. I just ..." He hesitated, wondering whether to tell her the truth, then suppressed the impulse and went on, "I guess I lost my temper."

Peri looked skeptical, but made no further comment. Timothy glanced out the side window. They'd driven out of Aynsbridge now, and were speeding along a narrow road lined with hedgerows. At first the route seemed unfamiliar, but then he started to see landmarks he recognized: there on the left was the wood where he'd happily lost himself on his first visit, and further down lay the pond he'd fallen into the last time, trying to catch the biggest frog he'd ever seen.

"I suppose you've been wondering why we haven't had you come and stay with us before," said Peri suddenly. "You probably thought we were ignoring you, but ..." Her hands lifted briefly from the wheel, shaping an apologetic gesture. "We've had a lot to deal with these past few months. It's nothing to do with you. I'm sorry we haven't been able to make you more welcome."

Timothy watched his own reflection in the window. He wished she hadn't brought that up: it just fired his resentment all over again. He'd expected to see a lot of Paul and Peri once he came to school in England, and visit them often at their big house in the countryside. But instead he'd spent all his holidays at his aunt and uncle's cottage in Tunbridge Wells, with neither cousin nor friend in sight. How long would it have taken Paul and Peri to acknowledge his existence, if he hadn't practically forced them to take him in?

"It's OK," he said, trying to sound like he meant it. "I'm here now."

"Yes," said Peri with an odd note in her voice, "you certainly are." She slowed the car as they reached the bridge, driving carefully over the ancient stones. The wood dropped behind them, bare trees yielding to a swath of brown meadow, and now Timothy could see Paul and Peri's house at last.

Oakhaven was nothing like the snug, whitewashed bungalow he'd left behind with his parents and sister in Kampala, and yet the sight of the old house gave him a sense of belonging he hadn't felt in months. He knew this place, from its foundations of warm grey stone to its ornamented gables, and everything about it said home to him in a way that no other place in England could.

Peri pulled the car into the drive and jumped out almost before it had stopped; by the time Timothy climbed out of the passenger seat, she was already hauling his luggage out of the back. "I can take that," he protested, but she strode past him, leaping up the ramp to the front door with his guitar in one hand and his suitcase in the other.

"Of course you can," her voice floated back, "but why should you? I'll just see if Paul's got dinner ready ..." and with that she disappeared inside.

Timothy shut the car door and slung his rucksack over his shoulder, looking up at the house. From the outside it hadn't changed at all: a tall Victorian design with arched windows and a neat box of front garden. Nothing special, in itself. But over its peaked roof he could see the topmost branches of the oak that had given the house its name, and his swollen mouth tugged into an involuntary smile. He tossed his pack onto the front step and headed for the garden gate.

The first time he'd...
