They all watched, recording their separate data on the computer, keeping an eye on earth from the heavens while their feet never left the ground. Hepton felt giddy sometimes, thinking to himself: this is the only earth there is, and we’re all stuck with it, every last one of us. At such moments, the thought of war seemed impossible.

The ground station at Binbrook was small by most standards, but quite large enough for its purpose, and it was sited in the midst of the greenest countryside Hepton had ever seen. He had been born here in Lincolnshire, but had grown up in 1960s London; ‘swinging’ London. It had swung right past him. With his head stuck in this or that textbook he had never quite noticed the bright clothes, the casual attitudes, the whole hippy shake. Too often, when his head wasn’t in a book, it had been raised to the sky, naming a litany of stars and constellations. And it had led to this, as though by some predetermined scheme. He had reached for the skies and had touched them. Thanks to Zephyr.

Zephyr was the reason behind all this activity, all these monitors and busy voices. Zephyr was a British satellite. The British satellite. It wasn’t the only one they had, but it was the best. The best by a long shot. It could be used for just about anything: weather-watching, communications, surveillance. It could drop from its orbit to within a hundred kilometres of earth, take a pristine picture, then boost back into the higher orbit again before relaying the information back to the ground station. It was a clever little sod all right, and here were its nursemaids, keeping a close eye on it while it kept a close eye on the British Isles. Nobody seemed quite sure why Britain was Zephyr’s present target. Word had gone around that the brass – meaning the military and the MoD – wanted to survey this sceptred land, which was fine by Hepton. He would never tire of staring at the various screens, seeing what his satellite saw, making sure that everything was recorded, filed, double-checked. And then viewed by the generals and the men in the pinstripe suits.
