A person got killed. Many lives, including the narrator's professional career, were twisted in result. The "London Accident" is a fascinating search for an answer: who did it? The search moves on from therapist's office to leading university department of psychiatry and law school, courts, asylum for criminally insane and finally ends up in the narrator's dining room. The perpetrator is not revealed until the very last page of the story. Nobody could have guessed until then.
