The Mystery of the Blue Train
Agatha Christie
Hardcover
(Dodd, March 15, 1928)
Aboard the luxurious Blue Train running from London to the Riviera, pampered millionaire's daughter Ruth Kettering is murdered, her expensive jewels stolen. Amid talk of an infamous jewel thief known only as the 'Marquis' being responsible, Poirot's suspicion falls closer to home, to Ruth's unhappy marriage. And sure enough, a witness comes forward claiming to have seen Ruth's flighty husband Derek entering her compartment before she was murdered. Christie claimed that this was one of the books she liked least, however the critics did not agree with her. The Times Literary Supplement said, 'The reader will not be disappointed when the distinguished Belgian on psychological grounds builds up inferences almost out of the air, supports them by a masterly array of negative evidence and lands his fish to the surprise of everyone.'
