Evil Smells Bad

""As a foulness shall ye know them...""

- The Necronomicon

Frequently, when a character enters an evil or cursed area they'll find that it smells really, overpoweringly bad. It usually smells of rotten flesh (or just "death") and grows more powerful as the investigator gets closer to the threat. Another variant is an evil being carrying a bad stench with it when it appears. Frequently one of the Horror Tropes.

This trope stems from the fact that dead and unclean things smell bad, so if somewhere or something smells bad, it's probably dangerous. The belief that demons smell of sulfur is also a contributing factor.

In The Tough Guide to Fantasyland, Diana Wynne Jones refers to this as the "Reek of Wrongness," which can take many forms besides just smell.

Anime & Manga

 * Watanuki from XXX Holic came across some situations like this, but he's the only one who can sense it. One example is at Himawari's friend's school where the game, Angel, is taking place.

Web Original

 * A few shorts of the Japanese horror anthology, "Tales of Terror From Tokyo" dealt with this trope, including "The Smell" where a young girl comes upon a kneeling woman who always faces her back and stinks of rotting meat (for some reason the smell prompts her to try to call the police right before the ghost woman does her wacky hijinks on her http://www.youtube.com/watch?v=aLxIhuVbRPk), and "The Smell of Animal" where the visiting niece is the only character who finds her aunt's husband has a horribly repulsive smell.
