Word has spread through the investigative comics' community that several facsimiles of Renee Montoya's (aka The Question) journal have been leaked to the public via sites like this one.
From what I've see online, there are some differences between the copies of the journal and the artifacts contained within the journal. And from what I've learned, this is NOT a publicity gimmick sponsored by DC Comics, but rather it's the careful dissemination of clues to a deepening mystery from writer Greg Rucka.

There is always a Question remaining to be answered.
