Greg's espersense found the cluster of minds, just as he heard the low bubbling laughter up ahead. Something about the minds wasn't quite right, their thought currents wavered giddily, emotions burning fiercely. One of them was emitting a mental keening, gibbering with psychotic distress.

"Shit. Teddy, it's a bunch of synthoheads. And they're juiced up high."

"Where?"

"Ten metres. One of the garages." He drew his Armscor stunshot, a simple ash-grey pistol with a solid thirty-centimetre-long barrel. "I'll take them, cover for any runaways."

"Gotcha."

The stunshot was only accurate up to twenty metres. If one of the synthoheads got away, Teddy would have to use the Uzi on them, providing the target laser worked in the fog.

Tension clamped down hard; this was supposed to be a stealth infiltration. People being killed just for getting in his way wasn't part of the deal.

It was the third garage from the end of the cul-de-sac, a dim yellow glow spilling out on to the sludge of rubbish. Greg flattened himself against the wall, checked the stunshot, then spun round the corner.

There were five of them. Kids, still in their teens, two girls, three boys. Filthy, greasy jeans, frayed black leather jackets, denim waistcoats with studs, long straggly hair. The garage walls were slick with condensation, junk furniture—broken settees and armchairs—lined up around the walls, and an oil lamp hung from the ceiling.

Greg's photon amp threw the whole scene into starkly etched focus. Two of the kids were screwing on the floor, grunting like pigs. Another two stood on either side, watching, giggling. The fifth was huddled in a corner, arms over his head, weeping quietly.

Greg shot the one closest to him. A girl, about seventeen, her neck freckled with dark infuser marks. The stunshot spat out a bullet-sized pulse of blue-white lightning. It hit her on the side of her ribcage. Her squeal was choked off as she reeled round. There was an impossibly serene smile on her face as she crumpled on to the legs of the rutting couple.

Pulling the trigger was incredibly hard. They weren't innocent, not even close. Just profoundly ignorant, pitiable. He had to keep on reminding himself the stunshot wasn't lethal, though God alone knew what it would do to a metabolism fucked up so badly by syntho.

He turned slightly. Aim and fire, nothing else matters.

The second kid gurgled as the pulse hit him in the stomach, curling up and falling forwards. Aim and fire. The girl on the floor was struggling to get up as her partner collapsed on top of her. Aim and fire.

The boy in the corner was looking straight at Greg, face ecstatic, tears streaming down. "Thank you, oh thank you."

Aim and fire.

The kid slumped down again, head bowed.

"Lord, what a waste," Teddy said. "Someplace else they could've been real people."

Greg stepped over the prone bodies and extinguished the oil lamp, letting the night claim its own. "You can get syntho anywhere."

"Not in Mucklands, you flicking couldn't. I look after my kids. Anyone tries peddling that shit near me an' they end up swinging by the balls. Blackshirts don't even look after their own."

"You're preaching to the converted. Come on."

According to the bright yellow co-ordinates the guido was flashing up, he was standing fifty metres from the target house. Its green template glowed lambently, the walls and roof remaining outside the photon amp's resolution.

"Colin, how are we doing?"

"He's still there, Greg."

"OK, we're closing in now."

He trotted down the road, watching the house gaining substance. It was a large detached three-storey affair, with bow windows on either side of the front door, built from a pale yellow brick with blue-grey slates. Nothing fancy, virtually a cube. Diamond shapes made from blue bricks set between the first-floor windows were the only visible ornamentation. A tall chimney stack was leaning at a worrying angle, a number of bricks from its top were missing. The chimney pots themselves ended in elaborate crowns, all of them playing host to tussocks of spindly weeds.

A metre-high wall enclosed a broad strip of garden at the front. Greg stopped just outside; it took him a moment to realize there were no solar panels. The house's residents must be right at the bottom of the human pile, and in Walton the bottom was as far down as you could get. All the windows had their curtains drawn; the photon amp revealed vague splinters of light round the edges. There was no gate, its absence marked by rusty metal hinge pins protruding from the wall.

He walked down the algae-slimed path. Dog roses had run wild in the garden, reducing into a thorny wilderness sprinkled with small pale flowers. A panel with eight bell buttons was set into the wall at the side of the door. Very primitive, there was no camera lens as far as he could see. He took the sensor wand from its slot on his ECM 'ware module, and ran it round the door frame. Apart from the lock system, it was clean.

"We're at the front door now," Greg said. He was surprised by the 'ware lock, a tiny glass lens flush with the wood. He already had the vibration knife in his hand ready to cope with a mechanical lock.

"I can feel you," Colin said. "Yes, you're very close now. He's above you, Greg. Definitely higher up."

"OK." He showed his card to the lock, using his little finger to activate it rather than the usual thumbprint. A Royan special was loaded in the card, a crash-wipe virus designed to flush lock circuitry clean. There was a subdued snick from the lock. He pushed the door open a crack, and slipped the sensor wand in.

"It's clear," he told Teddy.

The hall went straight through to the back of the house.

He saw a set of stairs halfway along. A candle was burning in a dish on a small table just inside the door. Its flame flickered madly until Teddy closed the door shut behind him. The lock refused to engage.

Greg let his espersense expand. There were four people on the ground floor, none of them showing any awareness that the front door had been opened.

They went up the stairs fast. The first-floor landing had five doors. One was open; he could just make out an ancient iron bath inside. His espersense picked out seven minds, two of them children. Murmurs of music from channel shows were coming through some of the doors.

"Which way, Colin?"

"Walk forward, Greg."

He took three paces down the worn ochre carpet. Teddy stayed at the top of the stairs, watching the other doors.

"Stop," Colin said. "He's on your left." The strain in his voice was quite clear, even through the satellite link.

"Thanks, Colin. Now you shut your gland down, right now, you hear?"

"Greg, my dear chap, there's no need to shout."

Greg let his espersense flow through the door. There were two people inside, one male, one female, sitting together.

Judging by the relaxed timbre of their minds he guessed they were watching a channel.

The door lock was mechanical, an old Yale. With Teddy standing behind him he. shoved the blade clean through the wood just above the keyhole and sliced out a semicircle.

Knebel's room was just as seedy as he had been expecting: damp wallpaper, cheap furniture, laminated chipboard table and sideboard, plain wooden chairs, a settee covered in woolly brown and grey fabric, its cushioning sagging and worn; thin blue carpet. The light was coming from some kind of salvaged lorry headlamp on the table, shining at the ceiling, powered from a cluster of spherical polymer batteries on the floor. An English Electric flatscreen, with shoddy colour contrast, was showing a channel current affairs 'cast.

Greg didn't know the woman, a blowzy thirty-year-old, flat washed-out face, straw hair, wearing a man's green shirt and a short red skirt.
