Series has wrong order

[Kathy]

Hello. This series (https://www.goodreads.com/series/1473...) has the wrong order. It should read:
1. Once upon a crime
2. Gretel and the Case of the Missing Frog Prints
3. The Case of the Fickle Mermaid
4. The Sorcerer's Appendix

For proof, I point to: http://www.stopyourekillingme.com/B_A...

And the fact that I just read books 1-3 and Gretel and the Case of the Missing Frog Prints clearly refers to the events and people introduced in Once upon a Crime.

Thanks!
