Meteorites fell through the night sky like a gentle sleet of icefire, their sharp scintillations slashing ebony overload streaks across the image Greg Mandel's photon amp was feeding into his optic nerves.

He was hanging below a Westland ghost wing, five hundred metres above the Purser's Hills, due west of Kettering. Spiralling down. Wind strummed the membrane, producing near-subliminal bass harmonics.

Ground zero was a small crofter's cottage; walls of badly laid raw stone swamped with some olive-green creeper, big scarlet flowers. It had a thatched roof, reeds rotting and congealing, caked in tidemark ripples of blue-green fungal growths. A two-metre-square solar-cell strip had been pinned on top.

Greg landed a hundred metres downslope from the cottage, propeller spinning furiously to kill his forward speed. He stopped inside three metres. The Westland was one of the best military microlights ever built—lightweight, highly manoeuvrable, silent, with a low radar-visibility profile. Greg had flown them on fifteen missions in Turkey, and their reliability had been one hundred per cent. All British Army covert tactical squads had been equipped with them. He'd hate to use anything else. They'd gone out of production when the People's Socialism Party came to power, twelve years previously. A victim of the demilitarisation realignment programme, the Credit Crash, the Warming, nationalisation, industrial collapse. This one was fifteen years old, and still functioned like a dream.

A time display flashed in the bottom right corner of the photon amp image, spectral yellow digits: 21:17:08. Greg twisted the Westland's retraction catch, and the translucent wing folded with a graceful rustle. He anchored it with a skewer harpoon. There'd be no danger of it blowing away now. The hills suffered frequent twister-gusts, and this was March, England's rainy season: squalls abounded. Gabriel hadn't cautioned him about the wing in her briefing: but Greg always followed routine, engrained by sergeant majors, and way too much experience.
