Earl Charles Spencer exposes the painful realities behind Princess Diana’s public fairy tale in his explosive memoir, Swan Song: Diana, My Sister. The personal tell-all tracks her life from childhood and her red-flag-filled marriage to Prince Charles to the aftermath of her fatal 1997 crash, detailing her private drop to 119 pounds, the terrifying press mobs that spat at her, and an astonishing parting conversation regarding her divorce.
Writing as both an investigative observer and a grieving younger brother, Spencer reveals personal regrets about missed warnings during Diana’s severe battles with bulimia and anorexia. He recounts reading his famed, searing funeral eulogy beside her coffin in private before ever stepping in front of the cameras at Westminster Abbey.
Inside the Royal Courting: Red Flags and Shocking Revelations
From the opening chapters of the charles spencer swan song book synopsis, Spencer reconstructs the escalating dread surrounding Diana’s royal entry. Three months before she accepted Prince Charles’s proposal, the British press erupted over the infamous “Royal Train Scandal,” reporting that Charles had hosted a nighttime tryst aboard the royal carriage with a mystery blonde woman. The media assumed the woman was Diana, but she was 50 miles away at the time and suspected the visitor was actually Camilla Parker-Bowles.
The warning signs multiplied during their official engagement interview in February 1981. When asked if they were in love, Diana eagerly answered affirmatively, while Charles offered his now-infamous reply: “Whatever ‘in love’ means.” Shortly afterward, Diana discovered a bracelet Charles had commissioned specifically for Camilla.
A Brother’s Private Meeting Before the Divorce
When Diana finally resolved to dissolve the royal union, she summoned Spencer, whom she affectionately nicknamed “Carlos.” While expressing full support, he voiced fears that the public might unfairly blame her for shattering the royal fantasy.
Diana’s response took him entirely by surprise.
“She looked up at me, nodded, and as her huge, sad eyes locked on to mine, she said in a quiet voice: ‘But, Carlos, my husband is in love with his valet.’”
Stunned by the unexpected claim, Spencer chose not to press her on the employee’s identity or the underlying evidence. For him, the singular reality that mattered was that her marriage—and the dreams tied to it—had irrevocably ended.
Private Battles: Severe Weight Loss and Academic Frustration

A heartbreaking throughline in Spencer’s narrative is Diana’s solitary struggle with severe eating disorders. Between her engagement and her wedding, remarks that she looked “chubby” triggered severe body dysmorphia. Spencer notes that her rapid weight loss resurfaced intensely following the birth of Prince William less than a year after the royal wedding.
Her physical decline escalated dangerously. Months before her death, Diana confided that her weight had plummeted to 119 pounds (8½ stone). Given her tall 5-foot-10 frame, medical professionals raised immediate alarms. Spencer admits deep personal guilt over failing to grasp how frail his sister had become, noting she found it slightly easier to acknowledge anorexia while guarding her bulimia behind total secrecy.
Spencer also re-examines Diana’s childhood schooling, arguing that she was severely failed by an inadequate educational environment. Addressing her lifelong academic struggles and resulting low self-esteem, he writes that he is convinced Diana lived with undiagnosed attention-deficit/hyperactivity disorder (ADHD), leaving her focus issues unaddressed throughout her formative years.
Myth vs. Fact: Unpacking Diana’s Protected Royal Status
Widespread assumptions often suggest that entering the royal fold immediately shielded Diana behind an impenetrable fortress of personal protection. Spencer’s recollections directly dispute that narrative.
| Topic | Memoir Revelation |
|---|---|
| Early Security | Because she was initially merely a girlfriend, Diana received zero police security, leaving her defenseless against press swarms. |
| Paparazzi Conduct | Paparazzi aggressively cornered Diana in public, with Prince William recalling photographers shouting, spitting, and reducing her to tears. |
| Eating Disorders | Her weight dropped to 119 pounds at 5-foot-10, alarming physicians while she hid her bulimia in near-total isolation. |
| Historic Eulogy | Spencer carried the draft in his pocket and read the entire speech to Diana’s body in the Chapel Royal before the public service. |
A Seething Mob and the Solitary Farewell

Before Diana had official security credentials, media packs swarmed her car, her apartment, and everyday errands without restriction. Spencer describes watching a “seething mob of men” descend upon a vulnerable young woman, calling the sheer physical intensity terrifying to witness in person.
This toxic environment deeply marked her children. Spencer documents that Prince William’s childhood recollections of his mother crying almost exclusively stemmed from invasive media harassment. The Prince of Wales vividly remembered photographers deliberately provoking his mother, shouting obscenities, and even spitting at her to capture an emotional, distressed photo for the morning tabloids.
“The reports failed to capture the terrifying energy of a seething mob of men around a fragile young woman. To view it in the flesh was truly shocking.”
Spencer’s journey with his sister concluded not under the glare of international television broadcasts, but in silence. One or two days before the massive public funeral service, he visited the Chapel Royal where Diana’s coffin rested for private family viewing. Pulling the handwritten speech from his coat pocket, he sat directly beside her body and recited the uncompromising eulogy aloud from start to finish, fulfilling a quiet, solemn promise before the rest of the world heard a word.
