He began to walk towards the cottage. The meteorites had gone, sweeping away to the east. Not proper shooting stars after all, then. Some space station's waste dump; or an old rocket stage, dragged down from its previously stable discard-orbit by Earth's hot expanded atmosphere.

"At twenty-one nineteen GMT the dog will start its run towards you," Gabriel had said when she briefed him. "You will see it first when it comes around the end of the wall on the left of the cottage."

Greg looked at the wall; the ablative decay which ruled the rest of the croft had encroached here as well, reducing it to a low moss-covered ridge ringing a small muddy yard.

A yellow blink: 21:19:00.

The dog was a Rottweiler, heavily modified for police riot-assault duty, which was expensive. A crofter with a herd of twenty-five llamas couldn't afford one, and certainly had no right owning one. Its front teeth had been replaced by mono-lattice silicon fangs, eight centimetres long; the jaw had been reprofiled to a blunt hammerhead to accommodate them; both eyes were implants, retinas beefed up for night sight. One aspect Gabriel hadn't mentioned was the speed of the bloody thing.

Greg brought his Walther eight-shot up, the sighting laser like a rigid lightning bolt in the photon amp's image, off two fast shots, maser pulses that drilled the Rottweiler's brain. The steely legs collapsed, sending it tumbling, momentum skidding it across the nettle-clumped grass. In death it snarled at him, jaws open, eyes wide, crying blood.

He walked past, uncaring. The Walther's condensers whined away on the threshold of audibility, recharging.

"At twenty-one twenty and thirteen seconds GMT, the cottage door will open. Edwards will look both ways before coming out. He will be carrying a pump-action shotgun—only three cartridges, though."

Greg flattened himself against the cottage wall, feeling the leathery creeper leaves compress against his back. The scarlet flowers had a scent similar to honeysuckle, strong sugar.

21:20:13.

The weather-bleached wooden door creaked.

Greg's espersense perceived Edwards hovering indecisively on the step, his mind a weak ruby glow, thought currents flowing slowly, concern and suspicion rising.

"He'll turn right, away from you."

Edwards' boot squelched in the mud of the yard, two steps. The shotgun was held out in front, his finger pressed lightly on the trigger.

Greg came away from the wall, flicking the Walther to longburn, lining it up. Edwards was a bulky figure dressed in filthy denim trousers and a laddered chunky-knit sweater; neck craning forwards, peering through the moonlit gloom. He'd aimed the shotgun at the ramshackle stone shed at the bottom of the yard.

The goat bleated, tugging at its leash.

Edwards was somehow aware of the presence behind him. His back stiffened, mind betraying a hot burst of alarm and fear to Greg's espersense. He tightened his grip on the shotgun, ready to spin round and blast away wildly.

"Drop it," Greg said softly.
