DEAR SIGLUND- I am writing to tell you I will never return. I said this once in anger, but now I tell you it is true. I live in San Francisco, a woman you would not know- a woman who eats white bread and fish, who owns a carpet but has no bed, who wears her hair cut short, grows dill and basil in a window box. This is a woman who will not live with her heart turned in, silent with guilt, bare and hard as quarry rock. She could never be her husband's nurse, his watch dog, his lost arm. Siglund, the houses here are steep. Colors fade and sharpen with the fog. There is water enough to bear ships and there is pageantry enough in me for all their coming and going. As you see, I have forgiven myself everything. Love, Nella Lucille Murphy
