I bet you'd look good in a coffin

My name is Kitty Collins and I'm a serial killer. I don't want to kill. It's just so hard to resist. Some men really, really deserve it. Men like Blaze Bundy, an anonymous influencer spreading misogyny online. He's making it very hard for me to control my murderous urges. Meanwhile I'm in the South of France to watch my mother marry a man I've never met. I should be drinking cocktails and focusing on my tan, not plotting a murder. Surely one more teensy little kill wouldn't hurt, would it?
