(The letter is deliberately not addressed to anyone, so that if it's intercepted Mikami can claim it was for Professor Vorkosigan. This is important, and Matsuda's arrival has made him slightly paranoid. Also, he can never bring himself to use God's name.)
I may have found a solution to the problem we discussed at our last meeting. I need to see you in person. Please let me know what time would be convenient for you.
