- All I see is a slight cloud of dust, maybe four miles back.
- Give me the glasses... Uh-hum. It's a car all right.
- But is it his car? Is it his?
- There's another coming too, further back.
- His is a gray Chrysler sedan.
- How can I be sure at this distance?
- The second's too far back to be a guard. Maybe the first is his.
- He's bound to be in one. If not the first, we'll wait for the second.
