I have got to stop reading prologues. They spoil the story for me.

Refreshing that the would be sleuth did not find the body herself, but that makes it a lot harder to give a convincing reason for the sleuth to get involved. Because she is curious? So is the town gossip, but that doesn't mean they go Spoiler breaking and entering and remove possible evidence. Mac hasn't finished her criminology degree, but you'd think that topic would have been covered in one of the earlier classes.

And why is she not getting a repremand from the nice detective? As much as I'm annoyed with cops that warn the sleuth not to get involved when all she does is talk to her neighbours (I haven't checked, but I doubt that's a crime in any part of the US), I'm more annoyed with a cop that responds with a "there, there, now" when a sleuth actually does something that can harm a criminal investigation.

There's a lot wrong with this book. Lack of attention to proper police procedure for one, proper puncuation of dialogue for another. And someone needs to tell the author about human metabolism:

That's not how the alcohol break down in your body works.
