A faint haze of small minds glowed around the wavering perimeter of his espersense, occasional twinkles within. Animals of some sort, clinging to a dour existence amid the ruins. Abandoned pets reverted to their true feral nature, rodents scrabbling to stay above the mud, an invasion of reptiles.

He pulled Gabriel roughly down the slope and into the bog which covered the street, ignoring her weepy cries of protest. They didn't have to swim. The syrupy mud drowning the tarmac was only a few centimetres deep, lapping over his feet like slushed snow. It was possible to wade. The raft of algae came up to mid-thigh.

Greg was nearly tempted to hide in one of the houses. None of them had doors or windows left. Pick one at random and cower down. Unless the hovercraft boasted some pretty sophisticated sensors, Kendric and Toby would never find him in time. But the dangerously dilapidated condition of the walls stopped him. If the tower went up with anything like the violence Gabriel claimed the friable houses would collapse on top of them.

They reached a mouldering dune which had once been a leylandii hedge, and squelched over it. Greg saw two white aureoles sliding fluidly across the horizon behind them, winding down through the slough channels. The drone of the hovercraft propellers drifted in and out of audibility. Kendric and Toby were fanning out, their search pattern carrying them further apart. At least it was only two.

He steered Gabriel down the narrow dank gully between two houses. There were animals on the other side of the walls, more than he'd originally thought, scurrying around frantically. The garden at the rear of the house backed on to another garden. Head-high panel fencing marked out the boundary, putrefying laths drooping under their own weight. In one corner was a greenhouse whose panes were pasted with hand-sized valentine leaves. Some abandoned horticultural treasure had thrived in the heat and abundant nutrient-soaked mud, making it look as though the aluminium-framed structure was about to burst apart at the seams.

Caustic fingers of silver-white light probed through a gap between a couple of houses a hundred metres away. The propeller noise was loud, fluctuating in strident piccolo whistles. Greg sensed Toby's churlish mind; the man was spite-laden, yearning to be the one who found the quarry. Instinct chafed at him. He knew Greg was nearby. A nature-ordained hunter.

The bulk of the houses blocked off the light as the hovercraft glided down the street. Then the questing fingers reappeared, closer this time, three houses away.

Greg urged Gabriel behind the greenhouse, and waited until the searchlight fluoresced the verdant avocado-green leaves.

The green corona died as the hovercraft moved on, but Greg knew that knot of determination in Toby's mind. He'd order the pilot to take the hovercraft down the gardens once he reached the end of the street.
