Fort William was the end of the line, its station just above the shore of Loch Linnhe. They stepped out onto the platform and Lawrence tipped his head back to look up at the mountain looming over the small town. The entire slope was covered with pine trees, their dark shapes packed tightly together.

"Is that Ben Nevis?"

"No," Joona said brightly. "That's Cow Hill; the Ben's away behind it. You'll be able to see it from Grandma's over in Benavie, if the weather stays fine." She glanced out at the choppy gray water of the loch. Dark clouds were streaming in from the southwest. "Rain's on its way."

Her grandmother was waiting in the station parking lot. Joona let go of his arm and waved frantically as she ran forward. Preconceived notions Lawrence had built up about Granny Beaumont being some quiet little old lady with her gray hair wrapped in a bun and wearing a long tartan skirt vanished there and then. The woman was only as tall as Joona, but she was a picture of health, with dark red hair only slightly tidier than her granddaughter's. She was wearing tough cord trousers and a long olive-green coat splashed in mud. He didn't see how she could be a grandmother to anyone in their twenties; she couldn't possibly be past fifty.

"So you'll be Lawrence, then." Her accent was thick, but easy enough for him to understand. They shook hands.

"Yes, ma'am."

"And we'll have none of that nonsense. I'm Jackie. Now come along with the pair of you, into the van. I've to pick up a few things first; then we'll go straight home." She ushered them forward. The van was a three-wheel pickup, with an egg-shaped driver's cab ahead of an open cart section. It must have been twenty years old, composite bodywork fraying along the edges with fiber strands bristling out of the cracks and odd-colored patches epoxied over the larger splits. The cab's curving windshield had yellowed with age and ultraviolet, reducing the visibility considerably. There was no steering wheel, just a broad handlebar.

"Still works, then?" Joona said.

"Of course. Sugarhol is the easiest fuel you can brew, and no duty on it, either. That's why they stopped making cells that could burn it."

Lawrence kept a perfectly straight face as he climbed into the rear of the pickup. The chassis rocked about as he tried to find a reasonably clean piece of floor to sit on. Joona passed their luggage over the tailboard to him, then climbed up. She pulled a thick woolen hat out of her coat pocket, then produced some gloves. "Don't worry, it's not far."

"Great." He zipped the front of his coat right up to his chin, then jammed his hands into the pockets.

Jackie climbed into the cab and fired up the converter cell. A cloying smell of burned sugar burped out of the exhaust, swirling around the vehicle. Lawrence wrinkled his nose up; his eyes started to water.

"There's a still up at the cottage," Joona said. "She ferments her own fuel. See what I mean about people hanging on to their independence?"

"Absolutely."

She laughed and gave him a hug before the pickup lurched off. Jackie Beaumont drove them north along the A82, which ran through the middle of Fort William. This section of town had large civic buildings on both sides of the road. He saw the hospital first, a modern two-story complex with an arched silver roof, its geothermal power turbine housed in a small igloo at the side. Two search and rescue helicopters were parked on their pads behind the accident and emergency annex. The information and heritage center was opposite. Next to that were several sports pitches, each covered by big translucent domes, similar enough to Amethi's nullthene to give Lawrence an unexpected twinge of nostalgia. The town administration office resembled a Georgian mansion with its vivid ginger brick and broad white stone windows. Only arches leading to the underground vehicle bays gave away its true century of origin. A line of buses had drawn up outside the secondary school. Kids in smart gray-and-turquoise uniforms were running around them, chasing balls and snatching each other's bags.

Just past the theater, Jackie turned into a parking lot serving a single-story wooden building that resembled a long barn. It had wide windows under the overhanging eaves, with displays of just about every kind of camping and walking gear ever manufactured. A carved sign over the door said Grimmers. Jackie hopped out of the cab and headed inside. Lawrence and Joona climbed down and followed her in. A cleaning robot was rolling through the nearly deserted parking lot, sweeping up leaves and mud.

"Looks like a good little community," Lawrence said as they went through the door.

She nestled up beside him. "A rich one, you mean. They can afford the facilities. A lot of companies combined to build the reclamation plants. There's a lot of tourism as well. The other end of town is virtually all hotels. Between them, they bring a lot of money into the area."

"That's good, surely?"

"Only if you've got a stake in it."

Jackie was picking up several boxes from a counter while the assistant chatted to her. Lawrence hurried over and took a couple of the boxes from her. She smiled her thanks and gave him a further two. They were heavier than he expected. The labels said they contained some kind of dyes.

"For the wool," Jackie said as they went back out to the van.

"Wool?"

"I'm part owner of a flock."

"Of sheep," Joona said, grinning.

"Right" It was a bizarre notion.

The rain had arrived, a thick, heavy downpour driven by strong winds. Turbulent clouds boiled overhead. Lawrence could see the last of the day's sunlight shining over the mountains on the other side of the loch. There was no sign of a rainbow. He put the boxes next to his own bag and clambered back into the van.

It was another ten minutes' drive back to Jackie's cottage, which was a few kilometers out of town. She drove them along the side of the Caledonian Canal before finally turning off onto a dirt lane that led through woodland of silver birch, oak and sycamore. Her cottage sat in a rambling garden, a long building with sturdy stone walls and lead-rimmed windows. A diamond brick chimney stack at one end was crowned by tall clay pots, with smoke curling away into the darkening sky. He expected to see a thatch roof, but the blue slate was just as acceptable.

Jackie drove the van into a wooden lean-to outbuilding on the gable end, which served as a workshop and garage. Water was overflowing from the guttering, sending a thick curtain pouring down across the doorway. The final deluge finished the soaking that the rain had been persevering with. Lawrence squelched down onto the concrete floor.

"Inside with the pair of you," Jackie said as she swung the big doors shut. "Go on now."

Joona led him through a side door into the cottage's kitchen. It was a wide room, taking up at least a third of the ground floor. The brick hearth was filled by a four-door Aga: its racing-green vitreous enamel had darkened down the decades, and there were plenty of little chips in it. But it was still functioning, throwing off a welcome heat Joona shrugged out of her coat and went to lean against it, gripping the tarnished chrome bar along the front.
