Special.

The wind outside nested in each tree, prowled the sidewalks in invisible treads like unseen cats.

Tom Skelton shivered. Anyone could see that the wind was a special wind this night, and the darkness took on a special feel because it was All Hallows' Eve. Everything seemed cut from soft black velvet or gold or orange velvet. Smoke panted up out of a thousand chimneys like the plumes of funeral parades. From kitchen windows drifted two pumpkin smells: gourds being cut, pies being baked.
