It was a cold night. Frost was settling on the ground, glinting where the security lights touched it. Rounding the corner of his rooftop patrol, Geertz paused and stared dutifully around, scanning the grounds with naked eye, then thermal goggles. Nothing, as usual. The last group of protestors had been nine months ago. Still, they had to stay watchful. Seeing Thompson and his Alsatian making a counter-circuit below, he waved a habitual ‘nothing’, then turned and paced away. The outer wall was three hundred yards away and ten feet high; a fence topped with razorwire separated the car parks and grounds from the compound itself. It would take an intruder several minutes to make the crossing, let alone get inside, and that was plenty of time for the guard patrols to spot them. Nobody was breaking in, not after that business four years ago.
Nobody human, anyway.
