Agatha Christie's 'Towards Zero'

The queen of crime thriller dame Agatha Christie is one of my most favorite authors. I like her novels and stories for two reasons. First, the plots of the novels and the stories and the other is that her characters and plots can be fitted anywhere irrespective of time and place. Sometimes i also feel that they are known to me. I can find them in everyday live. She had written 76 crime novel and short stories. Although 'Murder of Roger Acroyd' is considered as her masterpiece, in my opinion, her masterpiece is towards zero. In this novel, the main character Nevile Strange is a well known tennis player. Externally he is very sober and very sporting who always accepts his loss with smile. but in core he is cruel and revengeful. His first wife Audre Strange leaves him for another man. To take the revenge neville plot a murder of lady Tresselian in such a way that entire suspicion will fall on Audrey and she will be hanged for murder which she never commited. When audre saw that there is no way to prove her innocence she accepted the false charge against her and tried to take her own life. She was saved by a man called Mr. Macwhirter. he and superintendent Battle ( who is the incharge of the case) make a trap for Neville to make him confess. According to supt. battle it is not fair that in every detective story murder happens in first act. But murder should be the climax of the story. It will take place in the fifth act of the play. Every people and every incident will converge to that climax or that ultimate murder. In this novel, the climax is the murder of Audre Strange which is planed by Neville Strange. The murder of lady Tressilian is only a step of it, not the ultimate murder. I like this novel very much, because the novel is dependent on psychological crime, which is Agatha's specialty. Every character of this novel has a different type of psychology and you will find their natures familiar to you. We often see people like Neville, Audre, Kay (another character in the novel), Mary supt. Battle's daughter. In this novel Agatha creates a perfect climate of murder successfully.
