I was halfway down the embankment when I saw the red-orange flash. I dropped to the ground and covered my head with my arms. And felt a pain in my shoulder so intense I couldn’t even cry out.

Lying facedown in bracken and trash, I breathed in shallow panting breaths, a dog, eyes glazed, until the pain receded enough that I could move. I edged away from the flames on my hands and knees, then drew myself up on my knees and sat very still. I willed my breaths to come slow and deep, pushing the pain far enough away to manage it. Finally, I gingerly put a hand to my left shoulder. A stick. Metal or glass, some piece of the window that had shot out like an arrow from a crossbow. I tugged on the stick, but that sent such a river of agony flowing through me that I started to black out. I curled over, cradling my head on my knees.

When the wave subsided, I looked across at the factory. The back window that had blown apart was awash with fire, blue-red now, a mass so thick I couldn’t make out flames, just the blur of hot color. Bolts of fabric were stored there, fueling the blaze.
