Last week I was glad to receive your latest letter, and to see that your "multi Czar" code is coming along nicely. So far I have been unable to decipher it, which bodes well for the security of our future messages - but does feel a little frustrating. Rather ingenious, although I do fear it is vulnerable in some way I can't quite elucidate yet.
