In September 1997, Charles Spencer stood in Westminster Abbey before a watching world and shared his grief at losing his beloved sister, Diana, in a eulogy that was judged to be one of the great speeches of the twentieth century. Now, nearly thirty years later, he tells the astonishing story of his life with Diana and the tragic week of her death. Swan Song: Diana, My Sister marks the first time that Earl Spencer has spoken openly and at length about his sister. Earl Spencer says, 'With the 30th anniversary of Diana's tragic death on the skyline, I've been inundated yet again with requests for interviews about my sister. This has convinced me to write down my own thoughts and memories, once and for all, rather than having the discomfort of again reading the opinions of others, many of which are based on untruths that have become accepted over time.' 'The aim of this book is to tell the truth about Diana from her brother's perspective, just as I attempted to do when speaking at her funeral. As with my eulogy, I want to speak on Diana's behalf and do so in an openly positive way. 'I hope this book will be of interest to the many who still cherish the memory of Diana when she was alive, and I would be delighted if those too young to remember her in her heyday feel - after reading this - that they 'get' who she really was: a one-off, dynamic character, full of love, charisma and self-doubt, who gave life a hell of a go, and left the world a far better place, despite exiting the stage while still so young. 'This is a book I've been invited to write repeatedly, since the actual day of Diana's funeral. Now is the time for me to finally put it down on the page.' Daniel Bunyard says, 'This is a book of historic importance, telling as it does the story of one of the twentieth century's most iconic and culturally significant figures, but it is also utterly unique in being written by Earl Spencer, from a vantage point of such intimacy. It is extraordinarily moving, beautifully written and remarkably candid, in no small part due to Charles's rare ability to access great emotional depth without sentimentality, honest observation without rancour, and warmth without gloss. For the first time, but also for all time, readers will find here a fitting tribute to the beloved woman who was Princess Diana.'
