“Then we go through.” St. George looked up at her. “Can you clear it?”
The steel skull turned to the overpass. “You want it done fast or quiet?”
“A little of both, maybe?”
She nodded. “Give me ten minutes.” Big Red trembled as she moved back to the lift gate.
“A couple exes coming up the road behind us,” said Luke with a glance at his mirrors. “One’s pretty close.”
“You guys got ’em?”
The two men riding the lift gate down with the battlesuit gave St. George a quick thumbs-up. “Not a problem,” said Jarvis.
Cerberus stomped across the open road to the overpass. One armored arm swung up, seized the Civic axle, and yanked. The compact car flew out of the stack and skittered across the street. Her metal fingers clamped on the squad car’s rear end and dragged it free of the tangle of vehicles.
