They hugged the wall as the sharp crack of the double explosion sounded.

But he didn't get up again and a moment later the thin crack of a shot sounded across the snow.

At the same instant, the echoing crack of a rifle sounded.

The crack sounded like the snapping of a gigantic tree.

Here and there, a small, flat crack sounded on the moor.

Not even the crack of a rifle had sounded since sunset and the world seemed far away.

A loud crack, like a thunderclap, sounded in her mind as his hands came together.

Sharp cracks sounded, but they were not the shots of the machine gun.

A small crack sounded in the underbrush ahead, and he caught a glimpse of red hair.

She turned away, just as a sharp crack sounded from inside the school.
