Harry I’ve known for a while that it could be a 4×13 Playfair grid and the letters on it you get from coordinates using the 17 unique characters. But this case files 10.3 have revealed playing cards – now its obvious: A – ace, J – jack, K – king, Q – queen, X – 10, 2, 3, 4, 5, 6, 7, 8, 9, C – clubs, D – diamonds, S – spades, H – hearts. But I still don’t understand the meaning of it all and how to actually decrypt. Harry please remove as much as you want but please just let the message through. At this rate it will be an unmerry sleepless christmas
