Batman #21

Batman and Catwoman vs. the Suicide Squad!
A crucial device for Amanda Waller’s plans is hidden on a remote island under unprecedented security. Batman can get there without issue—but only one thief has the skill to steal it and keep it safe. Unfortunately, that will be the least of their problems.

Plus: a bonus story reveals the chaos unleashed in Gotham when the doors of Arkham are thrown open—and the Bat-Family is nowhere to be found.
