E.R. Punshon of "The Guardian" reviewed the novel in the 20 November 1936 issue when he began, "Even in a tale of crime and mystery humour is often of high value." He went on to say that, "In this respect... Agatha Christie shows herself once again... a model of detective tales. There are delightful passages when Poirot anxiously compares other moustaches with his own and awards his own the palm, when his lips are forced to utter the unaccustomed words 'I was in error', when Mrs Oliver, famous authoress, discourses upon art and craft of fiction. But all that never obscures the main theme as Poirot gradually unravels the puzzle of which four bridge-players had murdered their host." He concluded, "Largely by a careful study of the score, Poirot is able to reach the truth, and Mrs Christie sees to it that he does so by way of springing upon the reader one shattering surprise after another."
