Horror Aficionados discussion

Hey guys and gals, I'm looking for the title of a short I read about 10 years ago, the only thing I really remember is the protagonist is scared to speak of the thing, not sure if it's a beast, creature, evil or what. I believe they are in a cellar or basement, something of the sort. Anyone? Thanks in advance.

Sounds a lot like "Down There" which is in the "Dark Companions" collection. A secretary starts to believe there is something unpleasant living in the sub-basement of her company's office block. Hope this helps, Zombette, but I may be wrong.
