The weather turned with astonishing rapidity. One moment, sunshine was falling hot through the window onto Knox's cheek. The next, the sky was covered by thick black clouds and the temperature was plummeting. Rain played a few opening riffs on the Toyota's roof, then started drumming hard. Their headlights sprang on; their wipers started flick-flacking. They slowed with the traffic around them, picking their way through the fat puddles that formed quickly on the road.
Peterson indicated, then turned off the Nile road along a winding, narrow lane. They lurched from pothole to pothole, sending up huge splashes of spray. The deluge grew more violent, the clouds so black it might have been midnight. After twenty minutes or so they slowed to a crawl, briefly sped up again, then pulled off the lane over a shale verge and onto cloying wet sand. Peterson ratcheted the handbrake, turned off his lights, wipers and ignition, snapped free his seat belt. He opened his door, paused for a deep breath, then hurried out.
Knox sat up, cramps and pins and needles in both legs. A flicker of lightning revealed Peterson splashing his way back along the road, forearm over his head as a makeshift umbrella. Knox gave him a few moments, then opened the door and launched himself out after him into the full fury of the storm.
