Judith Mackrell, Bloomsbury Ballerina: Lydia Lopokova, Imperial Dancer and Mrs. John Maynard Keynes (Phoenix, $14.95 paper). She was a star of the Ballets Russes whose long list of lovers included Igor Stravinsky and Heywood Broun. He was a world-famous economist, a member of the Bloomsbury circle, and a confirmed homosexual. They were, in short, the least likely of couples–but they fell in love, married, and lived happily ever after, much to the dismay of Keynes’ viciously snobbish friends, Virginia Woolf foremost among them. Their story had previously been told in bits and pieces, but Judith Mackrell, the dance critic of the Guardian, has now given us an impeccably well-written book that pulls a half-forgotten ballerina out of the memory hole and restores her to her proper place among the key figures of twentieth-century ballet. Lopokova’s marriage to Keynes turns out to have been a full-fledged romance on both sides, and Mackrell describes it with sympathy and candor. Rarely have I read a better dance biography–or a more touching love story (TT).
