NEW YORK -- Shirley Lord, an English-born journalist whose early success on Fleet Street in London led to prominent jobs at Harper's Bazaar, Vogue and Helena Rubinstein, along with a sideline as the bestselling author of steamy novels, and whose high-dose vivacity and 1987 marriage to A.M. Rosenthal, the former executive editor of The New York Times, made her a society fixture and tabloid target, died June 10 in Manhattan. She was 93.
