Welcome to All About Agatha, the podcast dedicated to reading and drinking every single mystery novel written by the Queen of Crime, Dame Agatha Christie.

I am Kemper Donovan, and I have a lovely interview episode for you. I spoke recently with Y.A. author Martha Jocelyn, who has a series of Y.A. mystery books

But before I get to the interview, I have a few matters to discuss.

0:34.9

First, spoilers.

0:36.7

The following titles are spoiled during my conversation

2:04.6

that changed from Blackbro to Blackmore. Her first name acquired an H somehow. It went from N-O-R-A to
