Hercule Poirot, ”the little Belgian detective” of Christie, is never deterred from using his mind and his logic. Nevertheless, he is one of the few emerging detectives who were also concerned with the employment of imagination and intuition in the process of detection. This claim might be seen as debatable because one of the most characteristic features of the genre of the classic detective story is that it puts emphasis on the pure logic of the puzzle which is to be solved in order to restore the order of society unsettled by crime. However, the reason for the popularity of Agatha Christie resides in her ingenuity in varying the rules of the classic detective story but still remain within the boundaries of the genre.
