Story summary

On September 28, 2026, King Charles III and Prince William became furious after Charles Spencer, Princess Diana's brother, released his new book "Swan Song: Diana, My Sister," which includes explosive claims about the royal family. Spencer alleged that then-Prince Charles sounded "giddily elated" upon hearing of Diana’s death in 1997 and threatened to forget her soon enough. This reopened old wounds within the royal family and led to frustration and anger among royal experts, with Kinsey Schofield stating there is genuine anger at what amounts to an attack on King Charles' character almost three decades later. Prince William feels a sense of betrayal from his uncle’s actions as it involves reopening traumatic events from his childhood while damaging allegations are made about his father.
