Organize Your Corpses — Mary Jane Maffini

Charlotte Adams is a professional organizer. Nothing is out of place in her closets...but her life's a mess. So she's dumped her cheating ex-fiance, moved back home, and started making up to-do lists--some of which include solving the occasional murder...

There's no love lost between Miss Helen "Hellfire" Henley and pretty much the whole town of Woodbridge, New York. But just because she was a terror of a teacher doesn't mean she'd make a client. She just inherited an old house that she wants cleaned out, and Charlotte needs the money. But the job turns into a major nightmare when Charlotte learns she can't just toss the years of accumulated junk away--she has to dig through it to find some important documents left to Miss Henley. Instead, she finds her former teacher dead under a pile of the debris that plagued her, and there's no end of suspects -- starting with Charlotte herself.
