Rating: WORTHY!
This is one of three novels by Agatha Christie that I intend to review this year, the other two being Death on the Nile and Cat Among the Pigeons. I enjoyed all three of these in the ITV television series starring David Suchet as the consummate Hercule Poirot, but my experience with the novels was not the same. This one I really liked, though. Note that I already favorably reviewed Christie's The Unexpected Guest in July of 2013, and Thirteen at Dinner in November of 2014.
This one contains many of the tropes Christie routinely employed in her detective stories, including the usual array of foreigners: one Italian, one American, one French or German, and assorted Brits. It includes the young good looking guy, the young good looking girl, and the old crotchety woman. There is also the stock Christie signature ending whereby Poirot gathers all his suspects together at the end and slowly eliminates each until the murderer is identified. This to me is the weakest link, because none of these people would put up with this, and the police certainly would not. Fortunately for Poirot, the audience is already captive aboard the train, and there are no police here, only an official from the railroad. The role of official is usually played by a police officer, but there are other people who act as stand-ins, such as government officials. Here it's the railroad guy who lends Poirot authority as an agent of the railroad.
This story is so old that you very likely know the outline if not the filler, so I'm not going to launch into a detailed review here. The basis is that a truly bad man is traveling on the Orient express with a large assortment of other people. The express is full, which is unusual for the time of year. Poirot has encountered some of the passengers before he gets on the Orient Express, and meets many more aboard. The train hits a snowdrift and is stuck for several days. The night the snowdrift is encountered, the bad guy is bumped off, and Poirot naturally takes it upon himself to solve the crime. He has a harder time of it here than he usually does because of the nature of the death.
The victim was traveling under a false identity. He was stabbed twelve times, but the stab wounds offered no consistency: some were violent and deep, while others were shallow and weak. Some appear to have been delivered left-handed, whereas others were right-handed. There were some 'clues' which appeared to be false, whereas others appeared to be real, and the result of mistakes made by the perps(s).
The passengers are interviewed one by one, and Poirot slowly picks away at their stories until the rather unusual truth is revealed. I liked this story and the characters, and I recommend it.
