New case theory from our favorite hidden letters

I think our new case is probable going to have some elements of "The Problem of Thor Bridge" showing up in the next episode. Thank you, The Hidden Minnie for posting the letters so that the rest us Knights could see.

More thoughts on the letters

If it is some kind of code which kind is it? There are hundreds of different codes out there from the book code to the code that allows us to use computers the way we do. Or maybe there will be more letters in the credits of next episode. I wonder if the words Rat, Wedding, and Bow have any thing to do with the letters at the end of the episode. No, because Rat was simireveild in this episode with the Rat being the would be bomber, the one who unsuccessful attempted to blow the parliament building sky high.
