Truth and Beauty Bombs

What Batman comics have good coverage of the black mask? I never heard of him until all of the talk online about Batman 3. He sounds cool from what I've read online but I'd like to get my hands on a comic book about him. Can you recommend a good one?

The only important Black Mask story is War Games where he killed a couple of members of the Bat-family and ended up becoming the head of all organized crime in Gotham.
