And moved his hand on the wheel.

His front tyres slipped a little on the bridge ice and he corrected clumsily and his rear tyres swung the other way and fishtailed once, twice, three times. He slid across all three lanes. Saw a bus coming the opposite way through the falling snow. It was white. It was huge. It was moving fast. It was coming straight at him. The back part of his brain told him a collision was inevitable. The front part of his brain told him no, he had space and time and a grass median and two stout metal barriers between him and any kind of oncoming traffic. He bit his lip and relaxed his grip and straightened up and the bus blew past him exactly parallel and twenty feet away.

He breathed out.

The voice on the phone asked, ‘What?’

The lawyer said, ‘I skidded.’

The voice said, ‘Finish the report, asshole.’

The lawyer swallowed again and resumed talking, at the head of the previous sentence.

The man driving the white bus in the opposite direction was a twelve-year veteran of his trade. In the small world of his specialized profession he was about as good as it got. He was properly licensed and well trained and adequately experienced. He was no longer young, and not yet old. Mentally and physically he was up there on a broad plateau of common sense and maturity and peak capability. He was not behind schedule. He was not speeding. He was not drunk. He was not high.

But he was tired.

He had been staring into featureless horizontal snow for the best part of two hours. He saw the fishtailing car a hundred yards ahead. Saw it dart diagonally straight at him. His fatigue produced a split second of dull delay. Then the numb tension in his tired body produced an overreaction. He yanked the wheel like he was flinching from a blow. Too much, too late. And unnecessary, anyway. The sliding car had straightened and was already behind him before his own front tyres bit. Or tried to. They hit the bridge ice just as the steering told them to turn. They lost grip and skated. All the weight was in the rear of the bus. The huge cast iron engine block. The water tank. The toilet.
