Pita watched through the grimy, wire-enforced window of the Lone Star transport van as the vehicle backed up against a building with gray concrete walls and a large, metal-plated door. She swayed as the van bumped to a stop with its rear doors flush against the door in the building’s wall. Slowly, with a loud squealing noise, the building’s armored door slid up. Then heavy mechanical locks in the van’s rear doors clicked. The doors popped open a crack, letting in a slant of flickering fluorescent light.
