They were fifty metres from the forest when Nicole opened fire, her AK a subliminal rumble. The sentinel was hunkered down behind a bush, a clenched shadow, coiled up waiting to leap. It managed a short jump before the slugs bit into its skull. Crashing down into the watercress.

Teddy never even broke stride.

Eleanor trudged past the sentinel, dimly acknowledging how stately its huge head was, humiliated by cracked bone and ripped flesh. There was no honour in death, and it wasn't even a true enemy.

We malign life, she thought, suborning its grace and majesty to our own purpose, mocking it. Even the reservoir dolphins were a sin, so far from their true home, tame, unable to return. She knew water would never be a refuge for her again, not after tonight.

The stream's banks dipped down as they reached the forest, but the water remained knee-high. Tall acacias and virginciana trees threw boughs right across the stream; black heart leaves interlaced above Eleanor, blocking even the ashen phosphorescence of moonlit clouds. The trunks were knotted columns coiled by ivy and ipomoea vines; grape-cluster flower cascades dangled down, brushing against her head. A thick carpet of fleshy flowers covered the forest floor, tiny star shapes closed against the night, light grey in her image feed. She imagined the air would be thick with their scent if she removed her hood.

The forest had to be a human concoction, a designer ideal of fey woodland wilderness. Eleanor was staggered by how much it must've cost.

"OK," said Teddy. And she could hear him better this time. "So far, so good. Now, we've got a couple of lasers overlooking the stream before we reach the lake. Suzi, you trailblaze, clean 'em out. The rest of you keep watching for sentinels. This here is prime ambush country. When you leave the tree cover remember to keep yourselves below the water before you reach the lake; means crawling, but make fucking sure you don't let more than your head show. Those Bofors masers will zap anything over fifty centimetres in diameter. If you do get hit, dive fast, wind up cannibal lunch otherwise."

"What about the people inside Wilholm?" Victor asked. "They've got to know we're here after the racket the pickets kicked up."

Teddy patted the message laser. "We put this on wide-beam and use morse code to rap with 'em."

"Morse code!"

"Sure, man. Walshaw's ex-military, isn't he?"

"Yes," Victor agreed.

"Then he'll know morse. Tell him to take a look at you. Means your hood's gotta come off, though. You be careful."

"Careful. Christ."

"OK, let's move," Teddy barked.

Suzi took the lead, walking down the living wooden tunnel a couple of metres in front of Teddy.

The forest was alive with creatures, picked out by the infrared as quick-moving pink blotches snaking around the trees. Squirrels, Eleanor guessed. More pink spots slipped across the ground, not even disturbing the flowers. It was faintly macabre, seeing the unseen. Distracting.
