Accident is a short story, written by Agatha Christie.
In an English village, ex-Inspector Evans, late of the CID tells his friend, Captain Haydock (ex-Royal Navy), that he has recognized a local woman, Mrs Merrowdene, as being Mrs Anthony, a notorious woman who was charged and tried nine years previously with the murder of her husband by arsenic poisoning. She claimed that her husband was an arsenic-eater and that he took too much. Giving her the benefit of the doubt, the jury acquitted her and for the past six years she has been the wife of a local elderly professor. After recognizing her, Evans has carried out further investigations and found out that Mrs Merrowdene's stepfather died when he fell off a cliff path when walking with her one day. At that time, the stepfather had opposed the girl's (she was eighteen at the time of this incident) relationship with another man. Evans is convinced this earlier death was not accidental and that Mrs. Merrowdene is guilty of multiple murders.
Soon afterward, walking in the village, Evans meets and talks with Professor Merrowdene and finds out that he has just taken out a large insurance policy which will pay out to his wife should he die. Evans is more convinced than ever that Mrs Merrowdene is planning a third killing. He goes to the village fête where a fortuneteller foresees him being involved in a matter of 'life and death'. He meets Mrs Merrowdene at the fête and deliberately calls her Mrs Anthony, trying to provoke a reaction, but the lady remains composed. She invites Evans home for tea with her and her husband. Once there, she tells him they drink Chinese tea in bowls and then admonishes her husband for using the bowls for his chemical laboratory work, as it leaves a residue. Evans sees that she is about to poison her husband in front of him, using him as a witness. When Merrowdene leaves the room, Evans insists that the lady drinks from the bowl she prepared for her husband. She hesitates and then pours the contents into a plant pot. Evans is satisfied that he has prevented the murder and warns Mrs Merrowdene that she must not continue her 'activities'. He then drinks his bowl, chokes and dies on the spot. Having declared his suspicions of the woman, Evans was Mrs Merrowdene's victim, not her husband.
It is mentioned toward the end of the story that Inspector Evans was the third man who had threatened to cross Mrs Merrowdene and separate her from the man she loved; this means that Mr. Merrowdene is the man she loved when she was 18, and the three men were: her stepfather, Mr Anthony (whom she presumably did not want to marry), and Inspector Evans.
