The Life You Save May be Your Own

From the text:

"The early afternoon was clear and open and surrounded by pale blue sky;"

"Deep in the sky a storm was preparing very slowly and without thunder as if it meant to drain every drop of air from the earth before it broke."

"there was a guffawing peal of thunder from behind and fantastic raindrops, like tin-can tops, crashed over the rear of Mr. Shiftlet's car."
