Mary is a tiny, white-skinned, red-headed person who is often seized by little fits of self-consciousness. When this happens she averts her eyes from his and swallows, and when she swallows there is a certain cord in her white neck, rounding the concavity from shoulder to ear, that stands out for a moment. It draws attention both to her vulnerability and to the white flesh of her neck, which is not white in a pallid sick way but in another way that Waterhouse could never have understood until recently: viz., from his little stint in New Guinea, where everything is either dead and decaying, or bright and threatening, or unobtrusive and invisible, Waterhouse knows that anything this tender and translucent is too vulnerable and tempting to hold its own in a world of violently competing destroyers, that it can only be sustained for a moment (let alone years) by the life force within. In the South Pacific where the forces of Death are so powerful, it leaves him vaguely intimidated. Her skin, as unmarked as clear water, is an extravagant display of vibrant animal power. He wants his tongue on it. The whole curve of her neck, from collarbone to earlobe, would make a perfect cradle for his face.
