The final riddle

[Major Malfunction]

Ok so i finished the game on hard, i have deduced the identity of amadeus arkham and i have 239/240 riddles completed. I have back tracked through every single part of the game and looked at every riddler challenge map and it says there all complete.
Its driving me freakin nuts any ideas people?

[Count Mancy]

im not positive but i think to sol the last riddle you have to go back to Warden Sharpe's office.

[Staryn]

Go back to the penetentiary where you rescued Sharpe, by the cell with Clayface. The place where you got the Cryptographic sequencer. When you return, there will be some writing on the floor. That's the last piece.

[Escantell]

yeah, its the last part of the spirit of arkham. you're supposed to figure it out on your own. just go where sharpe last was, and its on the floor, and is activated same as the other spirit of arkham things.

Thanks guys but that was the 2nd last piece of the puzzle, i missed one trophy in medical.

I got a bug - I can't find teeth Joker 239\240 . Went around-probably not destiny .

[Escantell]

the riddler tab on the map/objectives menu tells the general location of the stuff. i personally had a few in the botanical gardens and the medical center that it took a while to find. just trawl all the rooms, they make those annoying sounds, so they aren'ttoo hard to find if you're paying attention.
