three hundred and something." Robert Barnard: "Not quite vintage for the period: none of the relations of the dead woman is particularly interesting, and the major clue is very obvious. The doggy stuff is rather embarrassing, though done with affection and knowledge. At the end the dog is given to Hastings – or possibly vice versa." References to other works Chapter 11: "Poirot's travellings in the East, as far as I knew, consisted of one journey to Syria extended to Iraq, and which occupied perhaps a few weeks". After solving a case in Syria by the request of his friend, Poirot decided to travel to Iraq before returning to England and, while in Iraq, was requested to solve a case, which he did and which is told in Christie's 1936 novel Murder in Mesopotamia, after which Poirot returned to Syria and boarded Orient Express to return home and en route solved Murder on the Orient Express. Chapter 18: Poirot gives a list of murderers from previous cases of his, more precisely Death in the Clouds (1935), The Mysterious Affair at Styles (1920), The Murder of Roger Ackroyd (1926), and The Mystery of the Blue Train (1928). Possible errata The son of Bella and Jacob Tanios is mentioned as Edward and, twice, as John in the novel. The boy is mentioned by name by his mother in Chapters 2, 16, 17 and by his father in Chapters 2 and 17 as well. At any other time, they are mentioned as "the children". At the very end of Chapter 16 in one print version, when Bella, her daughter Mary and Poirot are joined by Jacob Tanios and their son, Poirot asks Bella a question and she replies:"When do you return to Smyrna, madame?" "In a few weeks' time. My husband – ah! here is my husband and John with him."At the start of Chapter 17, Jacob Tanios then calls his son John:"Here we are," he said, smiling to his wife. "John has been passionately thrilled by his first ride in the tube. He has always been in buses until today."Other print versions have more switches between John and Edward (in Chapter 2 a few sentences apart, for example). However, in the audiobook edition read by Hugh Fraser, the boy is always called Edward, even in those two instances where the print version has the wrong name. Thus they are termed errata. It
