Smartest detective ever!!!

I have been read about fiction book then I was thinking of Hercule Poirot,pronounced /ɜrˈkjuːl pwɑrˈoʊ/; I have to put phonetic because his name is hard to read for people who study in English as second language likes me. Hercule Poirot was create by Agatha Christie. Poirot is really smart detective. He solves the criminal cases by his gray brain. Writer always make you follow the book imaginary.He also has a good friend to help him,Captain Arthur Hastings, when I was read a book I feel I cannot stop read it. So far I think that the author who write the novel was awesome!!. My favorite story is A.B.C. murders because this novel you CANNOT guess who's killer. You won't know since Poirot tell you at the end, author make you think that other person was a murderer. Moreover a serial killer want to kill himself when Poirot tell everybody that who was a murderer but Poirot know it!. Then he stole a gun from him. So this the reason why I like this story, he is not want a murderer die but he want a murderer to go to the jail.
