Nearly three decades after Princess Diana's death, her brother Earl Spencer has committed his enduring grief and grievance to a new book — one that places King Charles at the center of its criticism. The work arrives not as a sudden rupture but as the latest chapter in a long argument about how the House of Windsor treated a woman whose memory still unsettles the monarchy's self-image. Spencer has always insisted the full truth remains untold; this volume is his most sustained attempt yet to tell it.
