Night Landing

"Honey."

"Bees. It's a whole thing. Ask them about it some time when you're not in a hurry."

By ten the plain had gone properly black.

"Why's it freezing already?" Kit said. "It was thirty at lunchtime."

"Because this country takes about three hundred and twenty millimetres of rain in a whole year and tonight is none of it. No cloud, nothing to hold the heat in. The ground throws the day straight up at the sky, and an hour after sunset there's a skin of cold lying on the bitumen. Remember that. It matters later."

"There's someone coming," Kit said.

"There's not."

"There's a light."

"There's a light." Marnie did not change anything about her hands. "Watch it for ten minutes. Tell me when it gets bigger."

It did not get bigger. Kit reported this in a voice that had begun to dislike the news.

"Right. So here's the plain being clever. You've got a lid of cold air lying on the road with warmer air sitting on top of it. Cold air is heavier and it bends light harder. Layered like that, it works as a lens laid down flat along the ground. A beam that should have gone off into space gets bent back down and skates along inside the layer instead of leaving."

"Skates how far?"

"Tens of kilometres. Hundreds, on a good night. There's a bloke at a university who published the sums. What you're looking at is a real light from a real source, a station generator, a rig, somebody's verandah, sitting a hundred kilometres over the curve of the planet, and the air has lifted it onto the road in front of you."

"That's the Min Min."

"That's the Min Min, and it does nothing. You can't close on it, so it looks like it's keeping station with you. Change your line and the geometry shifts, so it looks like it backs off. All of that is you, not it."

"So it's harmless."

"It's a light with no size. Out here that's the opposite of harmless. No trees, no fences, no hills. Nothing to range against. Your eye can't tell four hundred metres from four hundred kilometres, so your brain picks a number, and your brain is a liar."

"Then how do you ever know?"

"You move. That's the whole rulebook. Change your position and watch what the light does. If it swings when you swing, it isn't there. If it holds and grows, it's real and it's close."

The radio broke in at 10:40.

"Any heavy vehicle eastbound on the Straight, this is Bight Air two-four, medical retrieval, I need you on this channel."

Marnie had the mike up before Kit could flinch. "Two-four, you've got a triple road train, twenty k west of the Caiguna turnaround. Go ahead."

Cardiac event, the pilot said. Station worker, forty-one, carried in to the roadhouse an hour ago and going nowhere good. Too far for the ambulance, too dark for the paddock. He was putting the aircraft down on the highway.

"On the road," Kit said.

"On the road," Marnie said, mike down. "Some of the widened bits out here are signposted as emergency strips. Runway markings painted straight onto the carriageway, turnaround bays scraped into the verge for the aircraft to spin in. It's a real strip. It just happens to have trucks on it."

"Eastbound," the pilot said, "I need both ends of that strip physically blocked and headlights on the painted numbers. Nothing enters once I'm on final. Can you give me that?"

"How long have I got?"

"Eleven minutes."

"Then I'm your west end. Who've I got for the east?"

A second voice came up, slow and friendly, calling himself Dossie, twenty-five metres of B-double running west, saying he had the far end covered and could see the strip already.

Marnie put her foot into it and did the arithmetic she had been doing all her working life. Eleven minutes. Nothing about forty tonnes is ever sorry, so she started slowing three kilometres out.

She came onto the widened section at a crawl and swung wide to lay the truck across the western threshold. Halfway through the swing, the far light slid sideways and came back.

"It moved," Kit said.

"It didn't move. I moved." Marnie set the brakes with a hiss that went on and on. "That's the test. Only test there is."

"And if you can't move?"

"Then you slow down until you can, and you wear whatever anybody says about it. Nobody has ever died of arriving late on this road."

Mist lay along the bitumen, ankle deep, pouring slowly off the edge of the seal.

"Is that fog?"

"That's the lid I told you about, and it's a thick one tonight. Watch what my high beam does in it."

The beam went two hundred metres and died flat, refusing to reach.

"Dossie, confirm you're on the east threshold."

"Sitting on it now, love. Nose west. I've got your headlights on the paint from here."

Kit frowned at the windscreen. "Then why can't we see his?"

Then the pilot, tight and flat, three hundred feet up.

"West end, I have one vehicle. One. I want two."

The cab went quiet enough to hear the chilled units running.

"Two-four, say again, there's a truck on the east threshold, I can see his lights."

"Negative. I'm above your cold layer, so I see what's actually on that road, and there is one truck on it, and it's yours."

"Dossie. Landmark. Not a light. What did you physically drive past."

"Cocklebiddy turnoff, love. Twenty minutes back."

"Cocklebiddy is the next roadhouse east of us," Marnie said, "and the roadhouses out here sit anything from sixty-five to a hundred and eighty kilometres apart."

"So he's nowhere near."

"He's parked across a widened bit of road that isn't this one, lining himself up on my headlights, and my headlights got to him the same way that first light got to us. Bent round the curve of the planet and laid flat in front of him."

The east end was open. And sitting down at that open end, where Dossie's lights should have been, was a light she had spent an hour teaching a passenger to ignore.

She let the truck roll forward thirty metres, putting her eyes somewhere new, and watched it.

It held. It grew.

"That's a truck," Kit whispered.

"That's a truck doing ninety, four hundred metres out, and he's dipped his lights for me because he's decided I'm a hundred k away." Marnie already had the gears. "He can't judge me. Nothing out here has a size he can trust."

Except one thing.

She ran the combination up the strip and hauled it broadside across the eastern end, all fifty-three and a half metres of it, three trailers swinging into the paint.

"Marnie, he's not slowing."

"He will. I've just given him something with a size on it." She had the mike against her jaw. "Westbound on the Caiguna strip, brake, brake, brake. I am across both lanes. I'm a road train. Count my lights and you'll know how close I am."

Because a road train side-on is not a light. It is a distance, laid out end to end for a man to measure.

The rear trailer's wheels found the soft limestone of the verge and it went over into the turnaround bay with a noise that took the whole night with it.

"Stopping," the radio said. "Stopping, stopping, stopping."

Air horns. Brakes screaming for eleven seconds. The B-double came to rest with its bull bar inside the length of Marnie's own shadow.

The aircraft came in over the top of the wreck and put its wheels on the numbers beyond it.

"Two-four is down," the pilot said. "Whoever built that wall at the east end, thank you."

Marnie watched forty grand of chilled freight bleed into the gravel beside a strip she had cleared and wrecked in the same movement.

"You wrecked it," Kit said.

"I bought eleven seconds. That's what they cost tonight."

"What happens to you?"

"Report, investigation, a photographer, and I wear that trailer for the rest of my working life." Marnie got the door open. "Come on. They'll want light held on the ground while they load."

They loaded the patient in six minutes. The aircraft spun in the turnaround bay, went off west, and its sound quit long before its light did.

The other driver came down the line of the wreck. Pav, he said his name was, and he wanted to know if she was all right.

"Ask me at Caiguna."

He stood looking at the trailer on its side.

"I've been sitting on a bloke's tail lights since Mundrabilla. Hour and a half, same gap, never gained a metre. That's why I had my lights down. I thought I was following him in."

Marnie looked east, down 146 kilometres of straight black road with a skin of cold air lying on it.

"Nobody was in front of you," she said. "Not since Mundrabilla."
