An air of romantic secrecy emanates from the Pacific Heights mansion of Danielle Steel. The author, who recently published her 50th best selling title, lives a life more dramatic than that of the most harried heroine from her many romance novels including Passion’s Promise, Now and Forever, A Perfect Stranger, and No Greater Love. In childhood Steel survived polio and cancer. Among her five husbands are a convicted bank robber/rapist and a heroin addict/burglar. Later husbands include a Silicon Valley investor and John Traina, a vintner and film producer who owns one of the world’s largest Fabergé collections. Steel herself is Saks Fifth Avenue’s best customer here. In recent years she has survived the heroin death of her 19 year-old son, as well as a relationship with actor George Hamilton. An international traveler, Steel’s lavish home base is the 55-room mansion at Washington and Octavia streets in San Francisco which was built in 1912 for sugar baron Adolph Spreckles and his wife Alma de Bretteville Spreckles.
