Dear Cammie,
I know I hurt you. I know you probably hate me but you should know that I still love you so much. And I have a secret to share. Catherine wouldn't want me telling you this but you deserve to know at least a quarter of the master plan
Catherine's building a machine called "The Indigo" and don't be fooled by it's a lovely name. It's pure evil. Which is why (of course) I love it. It is a human emp, capable of killing anyone without a trace of identification and would be passed off as a stroke or seizure. A perfect assassination weapon. And the best thing is it's small and discreet; Catherine's making millions.
I'm sorry I can't tell you more in case this letter doesn't fall into your hands but stay safe and go to Riverdale, they can help you.
Lots of Love Dad. MAM.
