Early Cases). This novel features (as the home of the heroine, Katherine Grey) the first mention in a novel of the fictional village of St Mary Mead, which had originally appeared in "The Tuesday Night Club" published in December 1927, which was the first short story to feature Christie's other famous detective Miss Marple. It also features the first appearance of the minor recurring character, Mr Goby, who would later appear in After the Funeral and Third Girl. The book also features the first appearance of Poirot's valet, George. Mere months after this novel was published, prolific French novelist Arthur Bernède published Le mystère du train bleu in late 1928. A murder mystery adventure featuring Bernède's own popular detective, Chantecoq, the story is set in Paris and the plot is completely different. It seems likely, however, that Bernède was hoping to benefit from Poirot's popularity. Literary significance and reception The Times Literary Supplement gave a more positive reaction to the book than Christie herself in its issue of 3 May 1928. After recounting the set-up of the story the reviewer concluded: "The reader will not be disappointed when the distinguished Belgian on psychological grounds declines to suspect the arrested husband and, by acting on the suggestion of an ugly girl who consistently derides her preposterous mother, 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". The New York Times Book Review of 12 August 1928 said, "Nominally Poirot has retired, but retirement means no more to him than it does to a prima donna. Let a good murder mystery come within his ken, and he just can't be kept out of it." British crime writer and critic Robert Barnard declared: "Christie's least favourite story, which she struggled with just before and after the disappearance. The international setting makes for a good varied read, but there is a plethora of sixth-form schoolgirl French and some deleterious influences from the thrillers. There are several fruitier candidates for the title of 'worst Christie'." References or allusions One of the characters in Death on the Nile recognises Poirot because of his involvement in The Mystery of the Blue Train: "Miss Van Schuyler said: ' I have only just realised who you are, Monsieur Poirot. I may tell you that I have heard of you from my old
