Orient Express, The Murder

There is a murderer on this train…or more than one! Yesterday, two of the passengers went missing, and just last night one was found dead. Mr. Hercule Poirot advised the conductor in charge and the police officer of the train to bring all passengers to him in the main restaurant of the train. However, before the door of the restaurant is locked, you receive a message from Mr. Poirot that reads: “Don’t come to the restaurant with the others. If I am not mistaken, the murderer may be here with us, but the proof of their guilt is not. I am leaving you all the information I have so far and will delay everybody for one hour, pretending that I am interrogating them, so you can identify the culprit. Good Luck.”
