Murder on the Orient Express

during the night on a several day train trip across lower Europe, Poirot's seemingly unpopular sleeping car neighbor is murdered. Rather than little or no clues or suspects, almost everybody aboard the train is a suspect; plenty of clues float around besides. Since the train is totally stalled due to a heavy snow, no resources other than sheer brainpower are available to our intellectual Belgian sleuth. Poirot gets by without his familiar sidekick, Capt. Hastings, but "adopts" a railroad executive and the traveling doctor as foils upon which to foist his evolving theories. After Poirot very cleverly determines that the victim is a hated child kidnapper/killer from America, the plot thickens as the interrogations proceed -- first one and then another and then another of the passengers seem to be related somehow to that long ago famous case. Could it be a conspiracy? You'll be turning the 200 pages rapidly to find out!
