In May 1934, a 41-year old woman met the 19-year old son she didn't recognise. 15 years earlier, she has scandalised high society by leaving him and his multimillionaire father and running of to Africa with a penniless man. Idina Sackville went to divorce a total of 5 men, yet when she died, there was a picture of her first love by her bed. An inspiration for Nancy Mitford, painted by William Orpen and photographed by Cecil Beaton, this is a dazzling portrait of the early 20th century.
