The Butterfly Conspiracy: A Merriweather and Royston Mystery by Vivian Conroy

She and her uncle are doing a presentation and she's brought her latest accomplishment:  A huge butterfly that is gorgeous and she brought to maturity at home.  The only problem is that the disbelievers make her open the container she had it in, it lands on the lady in the group, and she dies.  They accuse her uncle of murder...

Crooked Lane Books and Net Galley let me read this book for review (thank you).  It will be published August 7th.

She knows the butterfly wasn't poisonous.  The woman hadn't eaten or drank anything before she came or while she was there.  How could she have been poisoned?

I like this team of sleuths, they complement each other well.  They also work hard on the case.  

It's an odd little mystery but they solve it.  I hope to see more of this team in another novel.
