If any American fictional character of the twentieth century seems likely to be immortal, it is Lorelei Lee of Little Rock, Arkansas, the not-so-dumb blonde who knew that diamonds are a girl's best friend. Outrageous, charming, and unforgettable, she's been portrayed on stage and screen by Carol Channing and Marilyn Monroe and has become the archetype of the footloose, good-hearted gold digger, with an insatiable appetite for orchids, champagne, and precious stones. Here are her "diaries," created by Anita Loos in the Roaring Twenties, as Lorelei and her friend Dorothy barrel across Europe meeting everyone from the Prince of Wales to "Doctor Froyd"-and then back home again to marry a Main Line millionaire and become a movie star. In this delightfully droll and witty book, Lorelei Lee's wild antics, unique outlook, and imaginative way with language shine.
