Stuart Moore and Andy Clarke fill in for a two-part story, beginning in Detective 829 (Early May 2007).
Bruce Wayne is hosting an international anti-terrorism conference, which not everyone is happy about. Chiefly, the guy who sets off bombs within the Tower.
There he is. Vox. His agenda has to do with a fictional middle eastern country. He broadcasts to the police, but Batman realizes the signal is coming from inside the building. Batman is trapped as Bruce, with the delegates, and Lucius Fox.
Tim Drake managed to get to one of the secret “closets” and change into Robin, but Bruce is stuck with his cell phone, talking to Gordon. It all makes for a decent thriller.
Tim winds up face to face with Vox.
And as the story reaches its cliffhanger, Robin is coated in explosive goo, as Vox heads away to a safe distance before detonating it.
The story concludes in the next issue.
