Green Lantern, Vol. 3 #126A

Deep Cover
Shakedown has broken out of the Slab, and is killed when they try to recapture him. Unfortunately, he'd managed to kidnap his wife first, with plans to punish her for testifying against him. Kyle goes undercover with the other inmates to find out what happened to her, but he soon realizes there's a lot more going on at the Slab than imprisonment.
