An review kan The Times Literary Supplement kaidtong 3 Abril 1924 siring kaini: "When in the first of M. Poirot's adventures, we find a famous diamond that has been the eye of a god and a cryptic message that it will be taken from its possessor 'at the full of the moon' we are inclined to grow indignant on behalf of our dear old friend the moonstone. But we have no right to do so, for the story is quite original".An sabi man kan The Observer kaidtong 30 Marso 1924 , "The short story is a sterner test of the 'detective' writer than the full-grown novel. With ample space almost any practised writer can pile complication upon complication, just as any man could make a puzzling maze out of a ten-acre field. But to pack mystery, surprise and a solution into three or four thousand words is to achieve a feat. There is no doubt about Miss Christie's success in the eleven tales (why not a round dozen?) published in this volume. All of them have point and ingenuity, and if M. Poirot is infallibly and exasperatingly omniscient, well, that is the function of the detective in fiction."Sabi man kan The Scotsman kaidtong19 Abril 1924, "It might have been thought that the possibilities of the super-detective, for the purposes of fiction, had been almost exhausted. Miss Agatha Christie, however, has invested the type with a new vitality in her Hercule Poirot, and in Poirot Investigates she relates some more of his adventures. Poirot is most things that the conventional sleuth is not. He is gay, gallant, transparently vain, and the adroitness with which he solves a mystery has more of the manner of the prestidigitator than of the cold-blooded, relentless tracker-down of crime of most detective stories. He has a Gallic taste for the dramatic, and in The Tragedy of Marsdon Manor he perhaps gives it undue rein, but mainly the eleven stories in the book are agreeably free from the elaborate contrivance which is always rather a defect in such tales. Poirot is confronted with a problem and Miss Christie is always convincing in the manner in which she shows how he lights upon a clue and follows it up.
