What Happens, Part by Part (Contains Spoilers)

The fountain

At the Tallis country house, Briony watches from a window as Cecilia strips and dives into a fountain in front of Robbie. She misreads the moment as threatening. In fact, Cecilia was retrieving a broken piece of a vase.

The letter

Robbie writes Cecilia an apology but accidentally sends a crude draft. Briony reads it. That evening, she walks in on Robbie and Cecilia making love in the library and believes he is attacking her sister.

The accusation

Briony's young twin cousins run away. During the search, Briony finds her cousin Lola being assaulted in the dark. She convinces herself that the attacker was Robbie and tells the police. Robbie is arrested and imprisoned.

War

Five years later, Robbie, released to join the army, retreats with the British forces to Dunkirk, wounded. Cecilia, now a nurse, has cut off her family. Briony, eighteen, trains as a nurse in London, realizing the harm she caused. She visits Cecilia and Robbie to apologize and promises to tell the truth.

The ending

In 1999, Briony, now a famous novelist with vascular dementia, reveals that she wrote the story. Robbie died of septicemia at Dunkirk, and Cecilia was killed in a bombing in London. They never reunited. Briony gave them a happy ending in fiction as her final atonement. The real attacker was Paul Marshall, who married Lola.

5 Key Takeaways

  1. A single lie can destroy lives.
  2. Imagination can mislead as well as create.
  3. Guilt can shape a whole life.
  4. Fiction can try to make amends but cannot undo harm.
  5. Class prejudice shapes who is believed.
