Dear Husband
You did very well in killing Banquo. He was the biggest threat to your throne. However, I’m a little disturbed that his son escaped. You should have killed him as well, but no matter, we’ll deal with him later.
On a different matter, I’ve been having trouble sleeping recently, and when I do eventually fall aslep I have bizarre and vivid dreams. I’ve been to the apothecary, who gave me something that really knocks me out.
I almost forgot. I met three strange women the other day. They told me a ridiculous rhyme about how you will lose your crown. Don’t worry. Nothing can stop us now.
Your dearest darling, Lady M.
