He studied the terrain, the amp image grey and blue, smoky. There were no surprises; the Earth-resource satellite pictures Royan had pirated for him were three months old, but nothing had changed. The area was isolated, grazing land, marginally viable. Nobody spent money on barns and roads up here. It was perfect for someone who wanted to drop out of sight, a nonentity wasteland.

Greg heard a bell tinkling from the direction of the cottage, high-pitched and faint. He keyed the amp to infrared, and upped the magnification. A big rosy blob resolved into a goat with a broad collar dangling a bell below its neck.

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 Its front teeth had been replaced by mono-lattice silicon fangs, eight centimetres long; the jaw had been reprofiled to a blunt hammerhead to accommodate them; both eyes were implants, retinas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.
