The village doctor who solves the murder — and the detective who proves he committed it.
Who drives the story
The village doctor who narrates the case, plays Watson to Poirot, and turns out to be both Mrs Ferrars' blackmailer and Ackroyd's killer. His manuscript is his confession and his suicide note.
The retired Belgian detective next door, coaxed out of vegetable-marrow retirement to find the truth. He solves it with a moved chair, a dictaphone, and a reading of his own narrator.
The doctor's unmarried sister, a one-woman gossip intelligence service whose 'wrong' theories keep landing near the truth. Christie later credited her as a forerunner of Miss Marple.
The wealthy widower of Fernly Park, engaged to Mrs Ferrars and killed hours after learning her secret. His missing letter is the murder's motive and its map.
Ackroyd's stepson, secretly married to Ursula and pressured to marry Flora instead. His disappearance and his footprints make him the obvious suspect — and the obvious wrong answer.
Ackroyd's niece, engaged to Ralph, who lies about seeing her uncle alive to shield him. Her guilt over the lie cracks at Poirot's reunion, and Blunt's love finds her there.
The parlourmaid with no alibi, secretly Ralph's wife. Her garden meeting with Ralph is the innocent explanation for the night's most damning sighting.
The butler with a blackmailing past and a habit of eavesdropping, who denies making the phone call that summoned the doctor. Suspicious on every page, guilty of nothing but snooping.
Ackroyd's laconic friend, the last person besides Raymond to hear Ackroyd's voice. He confesses his love for Flora as the case closes.
Ackroyd's brisk young secretary, whose overheard 'It's all right' from the study becomes a key clue — the dictaphone at work.
Also in the story
Fernly's housekeeper, hiding an illegitimate son, Charles Kent, and a summerhouse meeting on the murder night. Her secrets are real but beside the point.
Russell's illegitimate son and a drug addict, arrested in Liverpool after his goose quill turns up. His visit to his mother is another red herring with a human cost.
