everal days before Christmas 2003, John Gregory Dunne and Joan Didion saw their only daughter, Quintana, fall ill with what seemed at first flu, then pneumonia, then complete septic shock. She was put into an induced coma and placed on life support. Days later--the night before New Year's Eve--the Dunnes were just sitting down to dinner after visiting the hospital when John Gregory Dunne suffered a massive and fatal coronary. In a second, this close, symbiotic partnership of forty years was over. Four weeks later, their daughter pulled through. Two months after that, arriving at LAX, she collapsed and underwent six hours of brain surgery at UCLA Medical Center to relieve a massive hematoma.
