From:

I assume from your hesitation that you're now reading the letter. I have to admit I was not in the kindest state of mind when I wrote it. You're free to roast me for my apparently incomprehensible punchline now.

[The letter inside, in familiar block-caps, reads:]

Dear Malcolm,

You have permission to check your warden item every two (2) days during ports, once (1 time) per day during floods that affect the environment, and every five (5) days otherwise, to verify I'm not face down in a ditch somewhere.

I will cooperate with up to thirty minutes of homework delegated to another warden per week, because despite your active detriment to my emotional state, I am taking graduation very seriously.

You are still to check my ledger.

Not entirely respectfully,
YOUR INMATE!

P.S. The puzzles are only going to get harder from here.
