It's hard to find a story in this book about writing a book, except in the few closing pages. It's one of Miss Cost's genteel entertainments for an elderly audience and it deals with Dinah Hogarth's attempt to do a revisionist biography of La Ferdel, once a Prima Ballerina Assoluta lost to her public since an earthquake in Chile in the '20's. Presumably dead, while actually she had disappeared into anonymity in a girls' school, later to be victimized by the rancorous life story of one Mr. Winter and free-floating gossip (had La Ferdel become a gambler?). During the course of Dinah's interviews here and there she learns the partial truth, finds a ring in another book and the lingering legacy of a royal romance. . . . All elaborated with decor and the habitual generic ""enchantings"" and ""deplorables."" Sometimes one pauses to wonder with Miss Cost--""How does one keep momently awake?
