Model response

The old mansion stood silent under the moonlit sky tonight. Inside the library a body lay sprawled across the carpet. Blood stained the antique rug near the victims head clearly. The frightened maid rushed to call the local police immediately. Detectives would soon arrive to investigate this heinous crime thoroughly. 
The lead inspector examined the scene with professional detachment later.
