In honor of Halloween, I decided to read a Batman graphic novel mtreiten gave me a while back. It's called Haunted Knight, and it's actually a collection of three stories that were apparently all published as Halloween specials.
Here's the thing: I've been blogging a lot about Heroes lately. It's probably my favorite new show of the season. And it turns out, the two guys mainly responsible for Haunted Knight are both involved in that show. Jeph Loeb, the writer, is credited as co-executive producer (as spacezombie pointed out in comments a while back). And Tim Sale, the artist, does all of Heroin Boy's artwork (paintings of the future, as well as the 9th Wonders comic book from the future that Hiro reads).
Synchronicity strikes again.
