Unpleasant Smell
The air was thick with the odor of sewage and decaying garbage. Dale and Mike both choked as they walked through the doorway to the room. Dale’s brain was working so hard that it couldn’t help but recall that the stench of rotten eggs indicated that inhabitants of the underworld were around in any of the stupid books that he had read in the past.
