300
You follow the highway twenty-five miles across Cochise County and, shortly before mid-afternoon, you arrive at a junction with Interstate 10. From here it is only a short ride west to the town of Benson, where you stop to take a closer look at the tyre tracks that are etched in the freeway’s dusty surface. You are convinced that they are made by the DC1 convoy, and you hazard a guess that they are at least a day old.
You are about to leave the tracks and return to your newly-acquired motorcycle when you hear something that sets your heart racing. It is the voice of a young woman and she is calling out your name.
