The first two years after the temperature peaked were the worst. Grass survived, of course, and some evergreen trees, but the sudden year-round heat wiped out entire ecological systems right across the country. Arable land suffered the least; farms, and the new kibbutzes, adapted readily enough, switching to new varieties of crops and livestock. But that still left vast tracts of native countryside and forests and city parks and village greens looking like battlefields scoured by some apocalyptic chemical weapon.

Repairs were uncoordinated, a patchwork of gross contrasts. It made travelling interesting, though.

Greg and Eleanor emerged from the spinney into a rectangular clearing which sloped down to the water. The dying bonfire illuminated a semicircle of twenty small chalets, and a big stone building at the crest.

"You live here?" Eleanor asked, in a very neutral tone.

"Yes," he agreed cautiously. The chalets had been built by an ambitious time-share company in conjunction with a golf course running along the back of the spinney, and a grandiose clubhouse/hotel perched between the two. But the whole enterprise was suddenly bumped out of business thanks to the PSP's one-home law. The chalets were commandeered, the golf course returned to arable land, and the hotel transformed into thirty accommodation modules.

Greg always thought the country had been bloody lucky the PSP never got round to a one-room law. The situation had become pretty drastic as the oceans started to rise. The polar melt plateaued eventually, but not before it displaced two million people in England alone.

"I never asked," she said. "What is it you do?"

He chuckled. "Greg Mandel's Investigative Services, at your service."

"Investigative services? You mean, like a private detective? Angus told me you had a gland."

"That's right. Of course it was nothing formal in the PSP decade. I didn't go legit until after the Second Restoration."
