The fleshing out of side characters is not the driving
force behind Benchley's work. With the shark occupying such a central focus in the
novel, and its pursuit at the hands of Brody, Hooper, and Quint, the other characters
are much more periphery. Of notable mention would be Brody's wife, Ellen. She is
depicted as one who struggles to act as the dutiful wife of the chief of police. She is
disenchanted with the family's economic situation, something reaffirmed during the
upcoming tourist season in Amity Beach:
readability="9">
She [Ellen] was born into the same
class as the summer residents — Benchley's own class, actually — and misses the luxuries
that are so much a part of their lives...Ellen becomes an
adulteress. She has an affair with a young oceanographer. Matt Hooper, whose family used
to vacation in
Amity.
In this
light, her role is peripheral to the central action. Mayor Vaughn might be another side
character whose function is to serve as more of a foil to Chief Brody. In rejecting his
decision to close the beaches in order to sustain economic interests, Mayor Vaughn
represents the inability to understand and embrace the force of
nature.
