Dear Red,
If you're reading this, you've gotten out. And if you've come this far, maybe you're willing to come a little further. You remember the name of the town, don't you? I could use a good man to help me get my project on wheels. I'll keep an eye out for you and the chessboard ready. Remember, Red. Hope is a good thing, maybe the best of things, and no good thing ever dies. I will be hoping that this letter finds you, and finds you well.
Your friend,
Andy
