As Red opened his mouth to talk, shouts came from far below, followed by gunfire. A deep explosion rattled the walkway. The cable shook with aftershocks and icicles showered him. The teacher shouted, slipped, and fell to spin at the end of her rope as a black, sooty cloud rose to envelop them. The choking smell of burning rubber filled Red’s nose. Another detonation hammered the Bridge and he stumbled, flapped for the lamppost, and held on, arms wrapped around the cold steel, feet swinging above the drop.
