‘What—?’

‘I’ll take you through to meet the Professor,’ said the woman. ‘Your . . . friend made certain arrangements.’

‘Florian?’

‘Not Doktor Horst. He’s . . . He went missing, along with Frau Horst.’

‘Missing?’

‘Perhaps they returned home.’

‘To Zürich?’

‘I understand Doktor Horst was from Stuttgart originally.’

Now Gavriela understood the woman’s reaction.

‘Oh. I can’t believe he’s . . . one of them.’

‘It was Herr Doktor Krause who made the work arrangements for you, before he left for England.’

Lucas is in England?

The woman tapped the envelope in Gavriela’s hand.

‘Save as much as you can,’ she said. ‘You might need it later.’

‘What do you mean?’

‘My cousin captains a fishing-trawler. But he never works for free.’

Six months later, Gavriela was throwing up over the side of that exact fishing-trawler, into the North Sea. In between bouts of paroxysm, she huddled inside the small wheelhouse with captain and crew, straining to make sense of reports broadcast by the BBC.

The woman at the Bohr Institute was Helga, and her forecast had been correct. April had been the beginning of spring - and of Nazi occupation. As grey-uniformed soldiers swarmed the streets, few citizens were anything but cold to them; but neither did they have illusions about their ability to fight back.

Not just Helga, but a whole string of friends helped Gavriela and others escape the country. When Gavriela asked why Helga stayed, Helga’s eyes had been fjord-grey, as unreadable as wild sea.

‘I have work here,’ she said.

Now the trawler captain, Helga’s cousin, spat through the open wheelhouse hatchway, and turned up the volume on the radio.

Far south of here, in France, from an obscure seaside town called Dunquerque, an incredible evacuation was taking place: a flotilla of military and private boats alike, thousands of them, taking the defeated British troops to safety, to their island fortress where they might regroup.

Nazi forces were sweeping like a riptide through Europe; the commentators were casting the story of Dunquerque as some kind of victory.

While on every side of the tiny boat, the massive ocean swelled and simply existed, huge and persisting, possessing a greatness no tiny, short-lived creature could enjoy.

THIRTY-NINE

THE WORLD, 5563 AD

Harij sat on the rough ledge, watching dawn come up over the canyon. Liquid highlights rippled on his silver skin, where his short tunic left his shining limbs bare. He was too hot already, while the rest of the townfolk would be sensibly asleep, deep in the cavern system behind him.

Below, the canyon was in shadow, almost hiding a mating-flight of dartbirds, the tri-winged creatures swooping as they swiftly joined in triplets before breaking apart, and soaring onwards.

The black-and-silver moon of Magnus was high to the east.

What’s that?

Surely he was the only one mad enough to be out in daylight. None of his classmates could imagine such a thing. But across the canyon, on the purplish mesa, a tiny figure was moving.

A Seeker?

Could it be? Distant, tiny, and robed against the heat. It had been so long since such a one had visited, but Harij remembered, and dreamed.

Then the tiny figure disappeared into a dip, was gone.

If only he could . . .

Something was in the void, just beyond the edge.

**A spin-glass Hamiltonian is analogous to an allele-suitability matrix in a context of fitness-suitability space provided gene mutations are epistatically interdependent in every—**

It drifted away, accelerating, for the flux was strong here.

But to be so close to an Idea!

He pulled himself to his feet, and moved along the ledge, wondering if he could yet reach out and grasp it before—

Too late.

For a second he was in danger of toppling over, but he caught himself.

So close.

He called out, unable not to.

**Come back, please.**

But the Idea tumbled on, in the air above the canyon, propelled by flux that paid no heed to one unhappy youth, however desperate his need for knowledge.

EARTH-CLASS EXPLORATORY EM-0036, 2146 AD

Rekka and Sharp stood within the microward boundary, looking around their old campsite, now renewed. There were three equipment cases standing open, although four cases had been designated for the mission. But she could not think of that, not now, because Sharp’s future was her main concern.

‘I’m willing to come with you,’ she said.

‘I know.’ The voice from his chest unit was soft, reflecting the subdued scent. ‘But they will believe me in the city.’

‘If you’re sure—All right, dear Sharp.’

‘I love you, Rekka.’

‘And I love you.’

His massive arms enclosed her, as she pressed her face sideways against his chest, inhaling the scent of his fur. She had no idea how his people would greet him on his return; she only hoped they were more open-minded than humans.

In fact, she thought they probably were.

‘You’ll walk to Mint City?’ she asked, drawing back.

‘It will give me time to . . . remember.’

After months on Earth, he needed to reacclimatize. She smiled at her friend’s wisdom.

‘Go well, Sharp.’

‘Go well, Rekka.’

Then he walked from the camp, his gait erect, his antlers wide and proud. Rekka stood watching until he was no longer in sight.

You’d better be safe.

But there were ways to help, still. Bending down at her biofact, she got to work, executing the pre-designed procedures. Within minutes, the first of her bees took wing.

She despatched them after Sharp.

FORTY-ONE

LABYRINTH, 2603 AD (REALSPACE-EQUIVALENT)

Carl-and-ship hurtled through Auric Void, howled past the edge of Mandelbrot Nebula, and a long time later burst into clear golden space near Labyrinth. Their distress signal gave them priority, and they tore along a docking tunnel into a wide space adjoining Med Centre.

It was his first public appearance flying a ship, destroying a false identity established decades ago. That counted for nothing.

Not with Miranda like this . . .

He disengaged his mind from his ship as they touched against the dock. Med-drones were waiting, along with medics, and as soon as his control cabin formed an entrance gap, a drone floated inside.

Panes of nothingness rotated, and three green-clothed medics stepped into the cabin.

‘It’s my wife . . .’

But the medics worked in silence, sealing Miranda, limp and bloody, inside the drone. Then the drone floated out, towards more waiting medics. Two of the medics in here backed off, summoned fastpath rotations, and twisted out of this reality-layer.

‘Can’t you rotate the drone through to—?’

‘Pilot Blackstone, your wife’s condition won’t allow it. A transition to another level would cause a trauma she’s not strong enough to cope with.’

‘Is she . . . Is she dying?’

‘We’re going to do our best to make her live.’

‘I—’

‘Excuse me, I must go.’ As the medic summoned the rotation, he added: ‘The staff on the platform will take you to her.’

Then he stepped into the twisting fastpath and was gone.

Carl rubbed his eyes, trying to get his bearings, swaying after the effort of wild flight. Then he noticed a lev-platform touching against the hull opening. Two Pilots stepped inside, neither of them dressed in medic green. One wore a goatee, the other was shaven; both were wide-shouldered and hard-faced.
