One of Christie's most famous mysteries, and deservedly so. It is a truly ingenious pure puzzle novel -- there is no description to speak of, and the characters are never more than their descriptions in the front of the novel. They don't need to be. It is a novel to be read simply for the sake of matching wits with Christie, and there are very few people who would win in that confrontation. My only objection is that the action Poirot takes at the conclusion of the novel do not seem in keeping with his stated philosophy in other books. Still, that is a minor quibble for an otherwise superb detective novel.
This is a classic murder mystery, and well deserves to be so. I have been reading Agatha Christie recently, and finally got around to reading this one. It is one of her better works, and rightly deserves to be a classic.
Things are not quite right from the very beginning, and lots of clues are around even before the murder occurs. And after it happens, oh the twisted web that abounds. Thirteen passengers, Poirot, the director of the rail line, a doctor, and a dead man snowbound on a train.
The ending is well done, but also quite different than most Poirot mysteries. I can't say anything more, and it is wrapped up, but sometimes, even Poirot's skill must go unheralded by the outside world. :)
