Lemke brought the cargo truck off the and accelerated down the corridor.  Of the three cops he'd hit with the trailer one was giving another first aid and the third lay still.  The other cops were reemerging from the bar kitchen doorway.  They paused briefly to fire again at the speeding transporter then sprinted after it.  Lemke glanced over his shoulder to see the cops shrinking in the distance.  Another glance showed him they had disappeared around the torus' curvature.  He spun the wheel and took the vehicle around a corner towards the central cylinder transportation core.  He passed several warehouse corridors, each wide enough to accomodate several cargo vehicles.  Down one corridor he saw a team of workers loading a vehicle similar to his own, but the silent operation of the electric motors let him pass without notice.  When he reached the closest of the massive freight elevators at the transportation core, he brought the vehicle to a stop then leapt to the floor.  The pain of his landing staggered him.  He steadied himself against the vehicle then drew a small maintenance diagnostic controller from inside his jacket.  He flipped open the black plastic cover and deftly entered commands into the tiny console.  The maintenance panel near the elevators controls clicked open and he pulled it open while taking a short network cable from his pocket.  He glanced behind him but there was still no sign of pursuit.  He disconnected the network cable from the main circuit board inside the maintenance panel and inserted his own, connecting the other end to the diagnostic controller.  He keyed in another set of commands and with a turning of gears the cargo gates began to open.  He withdrew his network cable, slammed the maintenance panel shut and pocketed the controller and its cale.  He vaulted over the lower cargo gate as soon as there was enough space to permit it, rolling into a crouch and hitting the button for the shipping dock at the planetside end of the habitat.
