“The drugs!  Ditch the drugs!  He’s coming!”

When Pete doesn’t immediately comply with my frenzied request to jettison the narcotics I grab his backpack and attempt to throw it into the brackish water.

“Take it easy man,” he says, wrestling the bag away from me. “We’re gonna be fine.”

Stanton has no reaction. He silently and expressionlessly pilots the boat from his position in the back.

Seized by terror I pull my knees into my chest, bury my face between them, and tell myself that if I don’t look at the boat creeping ever closer this nightmare will somehow end.

We got into New Orleans as it was getting dark, with no idea where to sleep. As Zara drove, I rummaged through her bag and found the card from the Holiday Inn we’d stayed at the night before and called their national helpline, aware that the battery on my phone was seconds away from torpidity and getting lower and lower.

I frantically navigated my way through the help menu options, stabbing at the buttons and praying that the battery would find a last ounce of charge.

At this point in time, I may or may not have been visualising Schwarzenegger in the final scenes of Terminator 2.
