Kilburn, 1873. The Tichborne Trial has captivated the widowed Scottish housekeeper Mrs Eliza Touchet and all of England. Readers are at odds over whether the defendant is who he claims to be – or an imposter.

Mrs Touchet is a woman of many interests: literature, justice, abolitionism, class, her novelist cousin and his wives, this life and the next. But she is also sceptical. She suspects England of being a land of facades, in which nothing is quite what it seems.

Andrew Bogle meanwhile finds himself the star witness, his future depending on telling the right story. Growing up enslaved on the Hope Plantation, Jamaica, he knows every lump of sugar comes at a human cost. That the rich deceive the poor. And that people are more easily manipulated than they realise.

Or such a range of living, breathing, surprising characters with such an idiosyncratically structured narrative? Michael Frayn
