There was an old lady who was a family "tyrant." She controlled every bit of the family, and everyone submitted to her. Anyone who moves arbitrarily must ask the consent of the old lady. As a result, they hardly spoke to anyone else. Sister Ka (convenient memory) secretly talks to others in the night, and the next day what awaits her is the "trial of the tyrant"; brother Erlei, who is an adult and has no social skills; brother Lei, who is married, but unable to rely on himself, and is afraid of self-reliance. Originally, they lived a life of isolation, but the old lady who took pleasure in dominating and torturing others had to travel and create opportunities for the children to get close to others. Because the self-proclaimed superior animal trainer is not satisfied with just flaunting her power in her small family. She was going to take her domesticated child to deal with more ferocious beasts, to find new stimuli.
But the children were eager to move. Sister Ka and Brother Erlei want to live a new life with the intention of murdering the old lady. Da Lei's wife asks Da Lei to go away with her, otherwise she will marry someone else. However, Da Lei was afraid of his mother, afraid of his new life. And there are five seemingly unrelated outsiders...
The result of the incident was naturally that the old lady was murdered. Conforms to the law of detective fiction "who does who dies". There is a similar psychological sadist in Grandma's "School Doubts" case, who takes pleasure in the secret and ugly things of others and threatens to torture others to show his authority. The old woman suffered from a heart attack and died of poisoning due to an overdose of foxglobin. Foxglobuxine is a drug used to treat heart failure, but in excess, it is poison. Grandma has worked as a nurse and pharmacist and has a deep understanding of drugs and poisons.
But who is the murderer?
Detective Poirot appears. Poirot's approach to the case was different from That of Sherlock Holmes. Holmes sees the micro-knowledge, and through the clues, he can deduce the whole situation. Poirot, on the other hand, is mainly through dialogue—the clash of languages, the discernment of truth from falsehood.
Reasoning is like doing multiple choice questions. The author will give you many options, and on these options, he will give you the corresponding information. There is only one truth, there is a disturbance option, and the corresponding information is the interference information. Of course, all the information is at the service of the main line. The key is to see if the reader can peel back the cocoon and find out the main line.
The most likely option is often not. The most likely murderer in this case is Erlei, and the real murderer is naturally not him. As in "Massacre in the Sun," the suspicious father is not a murderer. Although he appears in front of the reader's eyes many times.
The technique of thinking of each other as the murderer, but not the real murderer, is the booster of Grandma's story. This point is more content, and we will talk about it later.
Finale: The True Murderer Commits Suicide. Then the whole world was at peace. Poirot, the "professional red lady", witnessed the happiness of three pairs of lovers. Grandma's novel is like this, after the dark and mysterious murder, to find out the warm side of the world.
