how does steinbeck present curley's wife in chapter 4?

Curley's wife emerges in this chapter as both more complex and more loathsome than before. She is, on the one hand, much more than a one-dimensional harlot; at the same time, though, she represents a clear interruption of the socialist fantasy that the three men entertain. Indeed, she literally interrupts them at the height of their fantasizing. She is the snake - or, more to the point, the Eve - in the garden, the fact of life that makes a peaceful farm life so difficult, if not impossible, to obtain.
