If this book was the basis for the wildly successful Upstairs, Downstairs television series, then we must ensure that the show's writers and producers get all the credit they deserve. Here, the stories are lackluster and occasionally insulting to anyone under the age of 65, when Powell starts in on "kids these days." Powell, the second of seven children, grew up in a small English town where class separation was rampant. Despite her claims that it was better back then, money was tight, the family was too big, and she was ushered into domestic service at 15. Her use of many oblique references— like "hair sieves" and "aspic jelly"—will likely leave her readers cool or confused; the book is, above all, a litany of work the author hated to do. Powell fulfilled her lifelong ambition by marrying and, fortunately for us, left domestic service soon after that. Fans of the TV show who hope to find the same illuminating detail and descriptions of period life will be sorely disappointed. Agent: Jennifer Joel, ICM. (Jan.)
