From her debut novel 23 years ago, Zadie Smith has held both readers and critics in rapt attention. That debut was of course White Teeth, which went on to become a multi award-winning bestseller, and whilst the novels that have followed have taken readers to different parts of the world, she has for many been an essential chronicler of life in London. Her new novel, The Fraud, is set once again in our capital city but in a surprise to some, including the author herself perhaps, it is set during the Tichborne Case of 1873, making this her first historical novel. We spoke to discover what it was about this case and those involved in it that caused her to give in to the genre she had avoided so assiduously.
