I do not see anything different about it.
Is there realy a ‘twist’ to it?

I hope Madness doesn’t mind me saying that the subtlety here is to understand how the substitution is designed. It is not arbitrary, though it looks like it might be. There is a small twist on a classic cipher, and he is interested in seeing if you can work out what type of cipher has been used/adjusted and what the adjustment was. Is that right Madness? Harry
