Where is John Reinhardt? Some say he's returned to Heavenside as the strange radio voice of Doktor Sleepless. Some say his brain melted down a few years ago. Some say he's in an asylum in Heavenside and never left: including the cop who's pretty sure he put Reinhardt there, and, in fact, can still see him in his cell. So... who is Doktor Sleepless? And what's he doing with the weird implant technologies John Reinhardt gave to people three years ago?

If you feel cheated out of your flying car, the fourth issue of Warren Ellis' new satirical-political science fiction novel is just what the Doktor ordered!

The issue is available with a regular cover by series artist Ivan Rodriguez, or wraparound cover by Raulo Caceres, and also a rare 1-in-15 Future Warning Sign cover.
