What Not is Rose Macaulay's speculative novel of post-First World War eugenics and newspaper manipulation that anticipated Aldous Huxley's Brave New World by 14 years. Published in 1918, it was hastily withdrawn due to a number of potentially libellous pages, and was reissued in 1919. But by then it was quickly overshadowed by Macaulay's next two novels, and never gained the attention it deserved. What Not is a lost classic of feminist wit and protest at social engineering, now republished with the suppressed pages reinstated. Kitty Grammont and Nicholas Chester are in love, but Kitty is certified as an A for breeding purposes, while politically ambitious Chester has been uncertificated, and may not marry. But why? There's nothing apparently wrong with him, he is admired in his field, and is charming and decisive. Although Kitty wields power as a senior civil servant in the Ministry of Brains, which makes these classifications, she does not have the freedom to marry who she wants. They ignore the restrictions, and carry on a discreet affair. But it isn't discreet enough for the media: the popular press, determined to smash the brutal regime of the Ministry of Brains, has found out about Kitty and Chester, and scents an opportunity for a scandalous exposure. The introduction is by Sarah Lonsdale, senior lecturer in journalism at City University London.
