This was a scene from yesterday's Batman by Tom King and David Finch. A "war of jokes and riddles" shared between the Riddler and Batman and the idea that Batman did something very bad indeed. Was the Joker involved?

Yes. It's the Joker Vs The Riddler, and it happened years ago.

In June we will see the first issue of a new Batman arc, called…

…The War Of Jokes And Riddles by Tom King and Mikel Janin. Taking place in the aftermath of Year Zero, when The Riddler controlled Gotham for a whole year. It will run from Batman #25 to #32.
