Murder on the Orient Express the beginning

Agatha Christie is one of my favorite authors of all time! My favorite book of hers is And Then There were None. She is a suspenseful and skillful author who crafts all her books. They each have such amazing detail that you feel right in tune with the mystery. All her books are also somewhat linked having a same protagonist Poirot, who is an English mystery detective and a true genius in himself. Christie goes into depth with each character creating an interesting profile of everyone. So far in murder on the orient express Poirot has been stuck on a train that he was intending to go back to London on because of snow and during this time a tremendous accident occurs, one of the passengers is killed. It is a true who dun it mystery with all the passengers and even the protagonist himself being suspicious. A great aspect of this story is that anyone could have done it. The story line is not predictable and you are always guessing. Agatha Christie is one of the few authors who can keep me interested in a novel and she continues to do so with Murder on the Orient Express!
