Mardi Gras Murder: A Cajun Country Mystery by Ellen Byron

The city has flooded again and when they clean up the debris at the bridge base, they find a body.  He's not from around there and he's been murdered, not drowned in the flood.

Crooked Lane Books and Net Galley let me read this for review (thank you).  It will be published October 9th.

If that's not bad enough, one of the judges for the queen for this year, is shot and killed, too.  Is it because he opposed the Orphan Train Exhibit?  Or did someone want their daughter to win and his vote was going elsewhere.  Or was it something else entirely?

Maggie finds out he was blackmailing a lot of people but none of them would have killed him.

People in Louisiana are proud of their heritage and trace it back years.  No one wants an unknown relative showing up and changing the family tree.  That's why people are dying.  And Maggie needs to be real careful.  She's getting too close to the answer so the murderer comes for her...
