From Bill Crider's webpage comes a question: If you could write for the comic books, what would you want to write and why? Check out Crider's page for the link to his answer, as well as those of other crime writers.
For me, I'm into realism. But, I'm also an historian. Thus, I'd like to write an espionage story set in World War II and starring Batman who needs the help of the Justice Society to foil the bad guys. And, given the war, I'd have Batman's foes (Two-Face, for example) actually help Batman against the Nazis or the Japanese.
