The first thing that’s i thought of when reading the beginning was of Petunia Dursley from Harry Potter and how she was jealous of her sister and how that made her bitter, and I’m very interested to see if any of Petunia’s (rather poor) characteristics made it into the character. Otherwise, I’m very curious about the detective side of the story since mystery is very much my cup of tea since Sherlock đŸ˜‰!
