So it was the Martian who had sold out, not Nadia. He handed back the girl's dart-gun. "Here. See if you can't behave yourself now."
Nadia took the weapon. She pointed it deliberately at Gavin's chest. "Please clasp your hands behind your neck!"
The robot cab drew up at the curb. The door opened. It's voice issued from the loudspeaker. "Pit Seven."
"Get out," Nadia ordered. "Stand back from the door."
Gavin slid out. The buildings were gone, replaced by a wall of structural concrete which disappeared overhead in the clouds. It had begun to rain again, a clammy drizzle. The girl followed him to the curb, shivering as the drops hit her bare shoulders and back.
A green-lighted sign over a door in the concrete wall read:
PIT SEVEN—PASSENGER ENTRANCE
"In there." She motioned at the door.
Gavin, a step in advance, ducked inside and went ahead down a long incline until he fetched up in a mouldy unused waiting room.
