There is a hidden passageway behind some bookshelves. It's visible on detective mode. In Arkham City, it's only accessible by the members of the Bat-family, but can be used by anyone in Arkham Knight.
Exclusively in the Arkham Knight remastered version of the map, when playing as Batman, a piano can be played to reveal a crime board with notes consisting of multiple numbers and witness notes, similar to the one in Arkham Origins. The board appears to be an investigation into a murder prior to the start of Arkham Knight Batman was working on. Another prominate feature is what appears to be a cell door with 4-25 written on top of it. Some have speculated that this is tied to Rocksteady's upcoming announcement in April. Or it could be Batman's investigation on his parent's killer.
When the date arrived, a moderator posted a birthday congratulation for Joker, as he first appeared in the comics 76 years ago that day.
This is the only challenge map in Knight where Harley Quinn is the announcer; However, she never actually talks unless the voice synthesizer is used too much.
