[It is delivered to Ren's place of business, since Patrick does not have an address. The letter arrives at the coffee shop in an envelope, addressed to Adrian March, c/o Ren Solitaire. Inside, in Patrick's familiar scrawl:]
My bro,
I am old-fashioned, as you know, and therefore am writing this on paper and with a pen. I wanted to let you know that I am returning to Arborlon. There is something I did not take care of there that must be taken care of definitively before I can return to life here to build a life. I expect Newt will come with me, though that choice will be his to make. I would have come to see you, but you are inside a trunk, dude, and perhaps I did not wish to have a bad interaction with you before returning home. This does not mean I expect bad things to occur, but one never knows.
