As he fell, for the third time, I heard the crack of his revolver.

Behind them they heard the crack of a pistol, followed by a second shot.

I could hear the crack of a stone against his shield.

I heard the crack of a ball off a bat.

But worse than this were the times when they heard the distant crack!

I heard the crack of a broken branch from somewhere behind me.

I heard the crack and thought someone had shot off a pistol along the river.

Even over the wind I heard the crack as it hit the ground.

Somewhere off in the distance he heard the crack of a rifle shot.

When playing center field, he would hear the crack of the bat and count to five before taking a step.
