How about those writing true crime books? There must be others out there!
Wow, you're writing nonfiction books about fictional comic book characters AND true crime? Prolific.
On the board a half hour and already getting snarky commentary. Lovely. lol. In case you don't pay attention to the news, there is a true crime event that happened last year that does tie into Batman.
I know we have at least one other true crime writer around here somewhere.
