DC Comics has announced that following her historic run on Batgirl, writer Gail Simone is about to embark on a new (old) series, Secret Six.

So, what’s the secret? They’re not saying, but with covers and character designs by Dale Eaglesham and interior art by Ken Lashley, and Simone back writing the series, this has potential to be one incredible comic book.

Full of mystery and danger, Secret Six features six characters who, when thrown together, hate each other and must learn to work with each other.

Who are the Secret Six? Well, for now, Simone is only sharing a couple. Making their first appearance in The New 52 are Catman and Black Alice.

Secret Six issue #1 hits shelves this December.
