Mattie Winston is a nurse who catches her husband, David, cheating on her with another nurse. David Winston is a doctor at the same hospital she works at, so, not wanting to work at the same place he does, she quits her job and goes to work as assistant coroner for her friend Izzy, the coroner, who also gives her a place to live.
Her first homicide is the woman that her husband was cheating on her with. Not exactly a good way to start a new job, I'd bet. Not wanting her soon-to-be ex-husband the murderer (not that she ever thinks he is), she decides to investigate herself and find out who the killer is.
There were a few things that bothered me, but not enough to detract from the book. Example (not too much of a spoiler since it's only one scene): Mattie goes to a party wearing pantyhose that only go partly up her rear end, and she somehow expects them to miraculously stay up. A normal person couldn't even walk like that, considering you'd know they never would. You'd waddle (pantyhose are a little tight, and supposed to be that way). At this same party, her dress splits in the back and she doesn't even know it happened - I think I would know since the dress would be loose, not fit the same, and you'd definitely feel a breeze.
Aside from a few episodes like this, the book was pretty good. It was pretty funny and had a good mystery, which is why I rated it 4 stars. Definitely worth the read.
