Puzzles and Masks - Batman - PG-13

[seiberwing.livejournal.com]

Title: Puzzles and Masks
Fandom: Batman (1960s TV show)
Characters: Riddler, OC (canon immigrant). Referenced Riddler/Batman, OC/Batman.
Warnings: References to depression, massive amounts of ham.
Summary: The one riddle Batman cannot solve is the one he doesn’t even know is there.

While the comics pairing may not be rare, I've yet to see any fic at all for this...unique part of the Bat-multiverse.
