He stepped up on the blacktop and ran to the rear corner of the vehicle. Blowing snow pelted his face. He lined up on the lane markers and ran thirty paces back the way they had come. A curved trajectory. Thirty paces, thirty yards. Ninety feet. Near enough to eighty-eight. Eighty-eight feet per second was the same thing as sixty miles an hour, and plenty of lunatics would be driving sixty even in a snowstorm. He leaned down and jabbed a flare spike into the blacktop. The crimson flame ignited automatically and burned fiercely. He continued the curve and ran another thirty paces. Used the second flare. Ran another thirty and used the third to complete a warning sequence: three seconds, two, one, move the hell over.

Then he ran back and floundered through the ditch again and hammered on the door until the driver broke off his medical ministrations and opened up. Reacher climbed back inside. He brought a flurry of snow in with him. He was already seriously cold. His face was numb. His feet were freezing. And the interior of the bus itself was already cooling. The windows all along one side were already pasted with clumps of white. He said, ‘You should keep the engine running. Keep the heaters going.’

The driver said, ‘Can’t. The fuel line could be cracked. From where we scraped.’

Reacher said, ‘I didn’t smell anything when I was outside.’

‘I can’t take the risk. Everyone is alive right now. I don’t want to burn them up in a fire.’

‘You want to freeze them to death instead?’

‘Take over with the first aid. I’ll try to make some calls.’

So Reacher ducked back and started checking the old folks. The driver had gotten through the first two rows. That was clear. All four of the window-seat passengers were sporting Band-Aids over cuts from the metal edges around the glass. Be careful what you wish for. Better view, but higher risk. One woman had a second Band-Aid on the aisle side of her face, presumably from where her husband’s head had hit her after bouncing around like a rag doll.
