Mrs Ferrars died on the night of the 16th17th September - a Thursday. I was sent for at eight o'clock on the morning of Friday the 17th. There was nothing to be done. She had been dead some hours.

It was just a few minutes after nine when I reached home once more. I opened the front door with my latchkey, and purposely delayed a few moments in the hall, hanging up my hat and the light overcoat that I had deemed a wise precaution against the chill of an early autumn morning. To tell the truth, I was considerably upset and worried. I am not going to pretend that at that moment I foresaw the events of the next few weeks. I emphatically did not do so…

At 6:13 a.m. on a Friday morning Lucy Angkatel's big blue eyes opened upon another day, and as always, she was at once wide awake and began immediately to deal with the problems conjured up by her incredibly active mind. Feeling urgently the need of consultation and conversation, and selecting for the purpose her young cousin Midge Hardcastle, who had arrived at The Hollow the night before. Lady Angkatell slipped quickly out of bed, threw a negligee round her still graceful shoulders, and went along the passage to Midge's room. Since she was a woman of disconcertingly rapid thought processes. Lady Angkatell, as was her invariable custom, commenced the conversation in her own mind, supplying Midge's answers out of her own fertile imagination.

The afternoon of the 9th of September was exactly like any other afternoon. None of those who were to be concerned in the events of that day could lay claim to having had a premonition of disaster. (With the exception, that is, of Mrs Packer of 47, Wilbraham Crescent, who specialized in premonitions, and who always described at great length afterwards the peculiar forebodings and tremors that had beset her. But Mrs Packer at No. 47, was so far away from No. 19, and so little concerned with the happenings there, that it seemed unnecessary for her to have had a premonition at all.)

I have met people who enjoy a channel crossing; men who can sit calmly in their deck-chairs and, on arrival, wait until the boat is moored, then gather their belongings together without fuss and disembark. Personally, I can never manage this. From the moment I get on board I feel that the time is too short to settle down to anything.

I move my suitcases from one spot to another, and if I go down to the saloon for a meal. I bolt my food with an uneasy feeling that the boat may arrive unexpectedly whilst I am below…

Pure chance led my friend Hercule Poirot, formerly chief of the Belgian force, to be connected with the Styles Case. His success brought him notoriety, and he decided to devote himself to the solving of problems in crime. Having been wounded on the Somme and invalided out of the Army, I finally took up my quarters with him in London. Since I have a first-hand knowledge of most of his cases, it has been suggested to me that I select some of the most interesting and place them on record. In doing so, I feel that I cannot do better than begin with that strange tangle which aroused such widespread public interest at the time. I refer to the affair at the Victory Ball…

It was five o’clock on a winter’s morning in Syria. Alongside the platform at Aleppo stood the train grandly designated in railway guides as the Taurus Express. It consisted of a kitchen and dining-car, a sleeping-car and two local coaches.

By the step leading up into the sleeping-car stood a young French lieutenant, resplendent in uniform conversing, with a small man muffled up to the ears of whom nothing was visible but a pink-tipped nose and the two points of an upward-curled moustache…

I believe that a well-known anecdote exists to the effect that a young writer, determined to make the commencement of his story forcible and original enough to catch and rivet the attention of the most blase of editors, penned the following sentence: '"Hell!" said the Duchess.'

Strangely enough, this tale of mine opens in much the same fashion. Only the lady who gave utterance to the exclamation was not a duchess…

The events chronicled in this narrative took place some four years ago. Circumstances have rendered it necessary, in my opinion, that a straightforward account of them should be given to the public. There have been the wildest and most ridiculous rumours suggesting that important evidence was suppressed and other nonsense of that kind. Those misconstructions have appeared more especially in the American Press.

For obvious reasons it was desirable that the account should not come from the pen of one of the expedition staff, who might reasonably be supposed to be prejudiced…

The memory of the public is short. Already the intense interest and excitement aroused by the murder of George Alfred St Vincent Marsh, fourth Baron Edgware, is a thing past and forgotten. Newer sensations have taken its place.

My friend, Hercule Poirot, was never openly mentioned in connection with the case. This, I may say, was entirely in accordance with his own wishes. He did not choose to appear in it. The credit went elsewhere – and that is how he wished it to be. Moreover, from Poirot’s own peculiar private point of view, the case was one of his failures. He always swears that it was the chance remark of a stranger in the street that put him on the right track…

Hercule Poirot Frowned. "Miss Lemon," he said. "Yes, Mr. Poirot?" "There are three mistakes in this letter." His voice held incredulity. For Miss Lemon, that hideous and efficient woman, never made mistakes. She was never ill, never tired, never upset, never inaccurate. For all practical purposes, that is to say, she was not a woman at all. She was a machine-the perfect secretary. She knew everything, she coped with everything. She ran Hercule Poirot's life for him, so that it, too, functioned like a machine. Order and method had been Hercule Poirot's watchwords from many years ago. With George, his perfect manservant, and Miss Lemon, his perfect secretary, order and method ruled supreme in his life. Now that crumpers were baked square as well as round, he had nothing about which to complain…
