An old vicar falls dead during a dinner party. Everyone assumes it is of natural causes, even Hercule Poirot. But when yet another man, a famous doctor, dies in the exact same way at another dinner party, mr Poirot and his helpers are certain both cases are murders. But why would anyone murder a sweet old vicar? And whom among the dinner guests is the murderer?
A young girl is on trial for murdering her aunt and the girl who used to take care of the aunt. Even her attorney believes she is guilty. But the local doctor believes she is innocent and puts Hercule Poirot on the case. Poirot is not fully convinced of her innocence, because who else has the motive to murder both victims?
Hercule Poirot is on a holiday on a small island on the British Coast. He and the other guests observe an ongoing love affair between two of the guests, both married. And then the woman in the affair, a famous actress, is found murdered. There are many people who would liked to see her dead, but all of the guests have their alibis in order.
Poirot is invited to lunch but walks straight into a crime scene. He sees a body (a doctor) in the swimming pool and a woman (his wife) holding a gun. The wife swears she did not kill him, she just picked up the weapon. And again Poirot is looking for motives. Could it be the wife, the mistress or the woman he loved fifteen years ago that suddenly reappeared the day before the murder?
These four novels are collected in Poirot – 4 Classic Cases. The one I liked the least is the Hollow but they are all excellent crimes. What I like about Agatha Christie is that her novels are as much about human nature and every day life.
