The things I learned from watching Day of the Jackal
If you wait long enough at the airport, someone more or less your double will show up.
You can steal an arrivee's passport from his carry-on bag without arousing suspicion even if you're the only person standing next to him.
Weasel-faced guys who smart off with every sentence can be trusted with incriminating evidence.
Getting a little off an upper-class married woman is perfectly ok if you're on the lam...she won't testify against you, won't describe you or report you to the police, and after being told by the police you're dangterous she won't show any apprehension about being romantically involved with you.
I only have Clarol, dear.
