She picks up the new Navpack and asks it to activate.
The Navpack does not recognise her voice.
‘Activate!’ she repeats, desperation making the end of the word rise.
On her back, the sword begins to hum.
Vesper spins round, reaching for her gun, but the First remains where it fell, eyes still staring, glassy.
The sword’s hum rises sharply, pointedly, then stops.
With a happy ping, the Navpack activates.
A map shines onto the floor, showing Sonorous from above. The outer wall a thick dark line, curving like an inverted pair of horns, and, within it, a grid of roads, packed either side with little squares, countless. Vesper sees her location represented by a white dot that flashes excitedly. She taps it with a finger and the map zooms in, showing the house they stand in, the neighbouring ones and the criss-cross of alleys nearby.
Beneath them, purple, is another network. Passageways made for secret journeys, known only to the agents of the Winged Eye, entrances scattered about the island.
Vesper’s eyebrows shoot up. ‘This is it. Duet. Duet! I think I’ve found a way out.’
‘It doesn’t …’ she begins, but there is no-one to finish her sentence. She chokes back a sob.
Using the Navpack as a guide, Vesper moves across the room. The view zooms, scaling itself exactly to the space. A purple square of light overlays an incongruous corner. The girl runs to it, followed by the kid, who shares the excitement if not the understanding.
Fingers search for a gap or a handle, find none. Fumbling becomes frantic, a droplet of sweat falls from her hair, dampening dirt. Then, for no discernible reason, a square of plastic pops up, raising two inches proud of the floor. Vesper grabs it, heaves.
Cheeks turn from red to purple, muscles burn and the panel begins to lift.
With an excited bleat, the kid gets his head into the gap and pushes.
Girl and panel flip over, landing on their backs.
The kid tips forward, hooves scrabbling over empty air. For a moment he wobbles, precarious, then falls into the newly revealed hole.
There is the sound of an abrupt landing and disgruntlement.
Vesper scrambles to her feet. ‘Duet, look!’
She does, but nothing changes in her eyes. ‘It doesn’t …’ She twitches. ‘… Matter.’
Vesper’s hand finds Duet’s, squeezes. ‘Please come. I need you.’
Duet doesn’t squeeze back. Her head gives the smallest of shakes. But Vesper doesn’t let go and when Duet feels the pull, gentle, insistent, she is surprised to find herself moving.
Together, they descend.
From scattered places across Sonorous, black-visored figures stop, heads turning sharply. Leaving behind the soldiers at their backs, each one begins to run. Legs blur, making fan shapes beneath them as they race through the streets, faster than should be possible.
Witnesses can only stare and shiver.
Quickly, fourteen identically dressed figures converge on a house.
Inside are two bodies. One is of a man, aged by time outdoors, eyes staring towards infinity. They gather by the body. From two sword cuts and a hole made by angry light, essence escapes in little puffs of smoke.
Working as one, the figures capture the wisps, weaving them together. A coherent ball begins to appear, cupped in protective hands. At the same time, the group begin to excavate the essence in the body, clawing it out from the deep places, adding it to the ball. When they are finished, they close the man’s eyes.
Then the ball is taken to the second body, that of a woman, half of an abandoned Harmonised. They press it into the wound in her chest, then bind the cavity shut.
Any last spark of the woman flutters away in the flicker of eyelids.
The First opens its eyes and stands.
Restored, it lowers its head and the others do the same, until fifteen skulls tap together, sharing knowledge, making plans.
Less than a second later they break, ten of them sprint for the door, the other five move to an innocent looking corner of the room, reaching for the hidden doorway, glimpsed through dying eyes. But for the First, the panel refuses to open.
Gauntleted hands clench and the First leans over the rebellious plastic. Fists move like pistons, drumming, hammering, penetrating.
The passageway is narrow, forcing them on hands and knees. The kid bounds ahead, a perfect fit. From Duet’s visor a diamond flares into life, pushing back the gloom.
Vesper shoots her an envious look.
‘What?’
‘Nothing.’
They crawl on. Vesper lets out a sigh, murmurs: ‘I wish I had a torch.’
‘You’ve got …’ She pauses, taps the side of her head irritably. ‘… Two.’
‘I do?’
‘The Navpack … and the … gun.’
‘They’re torches?’
‘They’re torches.’
Distant drumming reaches them. Then a single crack, a dulled burst of thunder.
Duet accelerates, knocks into Vesper. ‘Go faster.’
‘What’s going on?’
She punches the girl in the back of the thigh. ‘Go faster!’
Vesper yelps, complies. Behind them comes a rasping sound, of lightweight plates sliding over stone, rapid and numerous.
In their haste, knees are bashed, knuckles caught on the tunnel’s sides, a catalogue of minor traumas to be pored over later. Several times the tunnel divides but Vesper doesn’t hesitate, following purple lines held tight in memory.
The sound of the hunters pauses.
Vesper slows, takes a breath to speak but Duet knocks into her, hissing in frustration.
When they come again, the sounds of pursuit are diminished.
‘They don’t know the tunnels,’ Vesper pants. ‘We’re dividing them.’
‘It doesn’t … matter. Even one … of them’s … enough.’
All at once, light hits the end of the tunnel. A solid wall, decorated by damp, and, in front of it, another hole. Vesper pulls out the Navpack and shines it down. The beam dances on water and bends around the long cylinder of an escape vessel, bobbing leisurely on the surface. Where the light hits the side of the hole, bars glint. Each one is as wide as a giant’s hand, inviting them to climb. Vesper does so.
Before she reaches the bottom, the cylinder cracks open, welcoming. Vesper drops from the last bar, her impact absorbed by the cylinder’s thick inner lining. Girl and tube wobble in the water but neither tips over.
Vesper rocks the cylinder gently, testing buoyancy. Then she shines the Navpack around the chamber, mapping a shape not much bigger than the boat she sits on. She points the Navpack down, switches it from torch to navigator. Lines of light quickly describe a way out. Vesper frowns. ‘The exit is below us, we need to go down.’ She pats the side of the cylinder. ‘In this. It’s safe, I think.’
Above her, in the tunnel, Duet crawls backwards. Slowly trying to rotate in the cramped space. ‘No.’
‘What?’
‘You go.’
‘What
