Plot hole: The local newspaperman points out Miriam to the insurance man before she gets out of the car, and the car is across the street - there's no way he could know it was her before she got out of the car.
Suggested correction: Of course he could have known her car, and since her husband was dead, who else would be in it?
Miriam didn't have a husband and Charlotte says in the film that she rented the car for Miriam.
