Person, place and thing.
These facts are important to ground your reader. However, just help them get their bearings. Don’t belabor the point and fill your pages with fluff.
Give them enough information and descriptions that let the reader understand what’s happening, who, what, where and when.

But don’t we all love to be lead down the path of a mystery? Too many details can kill the suspense.
