Mellifluous

Mellifluous is one of those words that I always wanted to be sinister. She was murdered in an alley by a mellifluous character who came at her from the shadows with a big knife. She never saw him coming, she didn't know he was there until his hands gripped her throat from behind. She only saw a momentary glint from the knife as it came down upon her.

But it actually means sweet sounding, musical.
