I have compiled a list of ideas but none seem to go anywhere.

– Trifid Cipher (I have tried so many group sizes)
– Substituting every three characters (e.g /// with a) and then trying vigenere or autokey
– Morse Code with another layer afterwards (. = \ and – = ||)
– Trifid followed by vigenere or autokey
-Trifid followed by transposition cipher

Dear Harry, please tell me if one of these is correct. And could the next hint be a little more revealing? Thanks.

The clues will get more revealing, but only slowly. This is a tough cipher but if we give too much away at once it will become an easy one! Harry
