My Dearest Jackson,
I hate to have to write you this letter, but I'm afraid my secret is out. I know there will be questions I won't be able to answer. No doubt they'll come looking for me, but by the time you read this I'll have already fled the country. I hope you understand how difficult of a decision this was for me. That's why I ask that you don't come looking for me either. I'll write to you as soon as I can.
Until then,
GF
