"Dear Walt,
just a short note because these might be the last letters we will get across the fascist lines via a trusted courier.
Forget what I wrote a few weeks ago. I'm very thankful you've sent Randall Brown. He might be a greenhorn, but he sure has his shit together. It's safe to say I wouldn't be still around without him.
Anyhow, you take care, will you? I mean, I've survived worse, but it doesn't look good and I wouldn't place a bet on our lives.
Take care,
Lix"
