He reached inside his trenchcoat and pulled out a good-sized leather-bound journal. Where he'd found the space to keep that thing was a question for another time. (The answer was that there was a lot of room in that trenchcoat's hidden pockets.) Raju might have been able to catch what was stamped on the front of it: the years 1985-1986. "Keep one myself."

Hence why he'd decided to help Raju in the first place. Anyone who kept a journal couldn't be all bad in Rorschach's book. Then he put the journal back from where he's gotten it from.
