Judy Jones is shown to be the woman of Dexter's winter dreams, as it is meeting her in her youth that causes him to quit being a caddy and sets him on his course towards wealth and prosperity. The allure of Judy's beauty and the promise that she contains is what spurs Dexter on, and with this regard the way that she is described when Dexter sees her as an adult is very important. Note how Judy Jones is presented when Dexter meets her yet again on the golf course:
She was arrestingly beautiful. The color in her cheeks was centered like the color in a picture--it was not a "high" color, but a sort of fluctuating and feverish warmth, so shaded that it seemed at any moment it would recede and disappear. This color and the mobility of her mouth gave a continual impression of flux, of intense life, of passionate vitality--balanced only partially by the sad luxury of her eyes.
The superlative attributes that she possesses therefore are her beauty, which is described as being "arresting" in its ability to make others sit up and take notice of her. However, the overwhelming impression the reader receives from this description in addition to her beauty is the way that she is so full of life, "intense life" and "passionate vitality." It is this superlative description that makes Judy Jones such an alluring figure to everyone around her, and especially to Dexter. She represents life in all of its fullness to him, but also note the "sad luxury" of her eyes, which perhaps foreshadows the way that his winter dreams of being with her are elusive and the sadness that his pursuit of her will bring.
