report was handed to the judge who read it with great interest and it was then passed on to the jury.
‘We congratulate you on your acumen. The case is becoming much clearer. The drugged cocoa, taken on top of the poisoned coffee, amply accounts for the delay which puzzled the doctor.’
‘Exactly, Mr Le Juge. Although you have made one little error; the coffee, to the best of my belief was not poisoned.’
‘What proof have you of that?’
‘None whatever. But I can prove this – that poisoned or not, Mrs Inglethorp never drank it.’
‘Explain yourself.’
‘You remember that I referred to a brown stain on the carpet near the window? It remained in my mind, that stain, for it was still damp. Something had been spilt there, therefore, not more than twelve hours ago. Moreover there was a distinct odour of coffee clinging to the nap of the carpet and I found there two long splinters of china. I later reconstructed what had happened perfectly, for, not two minutes before I had laid down my small despatch case on the little table by the window and, the top of the table being loose, the case had been toppled off onto the floor onto the exact spot where the stain was. This, then, was what had happened. Mrs Inglethorp, on coming up to bed had laid her untasted coffee down on the table – the table had tipped up and [precipitated] the coffee onto the floor – spilling it and smashing the cup. What had Mrs Inglethorp done? She had picked up the pieces and laid them on the table beside her bed and, feeling in need of a stimulant of some kind, had heated up her cocoa16 and drank it off before going to bed. Now, I was in a dilemma. The cocoa contained no strychnine. The coffee had not been drunk. Yet Mrs Inglethorp had been poisoned and the poison must have been administered sometime between the hours of seven and nine. But what else had Mrs Inglethorp taken which would have effectively masked the taste of the poison?’
‘Nothing.’
‘Yes – Mr Le Juge – she had taken her medicine.’
‘Her medicine – but …’
‘One moment – the medicine, by a [coincidence] already contained strychnine and had a bitter taste in consequence. The poison might have been introduced into the medicine. But I had my reasons for believing that it was done another way. I will recall to your memory that I also discovered a box which had at one time contained bromide powders. Also, if you will permit it, I will read out to you an extract – marked in pencil – out of a book on dispensing which I noticed at the dispensary of the Red Cross Hospital at Tadminster. The following is the extract …’17
‘But, surely a bromide was not prescribed with the tonic?’
‘No, Mr Le Juge. But you will recall that I mentioned an empty box of bromide powders. One of the powders introduced into the full bottle of medicine would effectively precipitate the strychnine and cause it to be taken in the last dose. You may observe that the “Shake the bottle” label always found on bottles containing poison has been removed. Now, the person who usually poured out the medicine was extremely careful to leave the sediment at the bottom undisturbed.’
A fresh buzz of excitement broke out and was sternly silenced by the judge.
‘I can produce a rather important piece of evidence in support of that contention, because on reviewing the case, I came to the conclusion18 that the murder had been intended to take place the night before. For in the natural course of events Mrs I[nglethorp] would have taken the last dose on the previous evening but, being in a hurry to see to the Fashion Fete she was arranging, she omitted to do so. The following day she went out to luncheon, so that she took the actual last dose 24 hours later than had been anticipated by the murderer. As a proof that it was expected the night before, I will mention that the bell in Mrs Inglethorp’s room was found cut on Monday evening, this being when Miss Paton was spending the night with friends. Consequently Mrs Inglethorp would be quite cut off from the rest of the house and would have been unable to arouse them, thereby making sure that medical aid would not reach her until too late.’

‘Ingenious theory – but have you no proof?’
Poirot smiled curiously.
‘Yes, Mr Le Juge – I have a proof. I admit that up to some hours ago, I merely knew what I have just said, without being able to prove it. But in the last few hours I have obtained a sure and certain proof, the missing link in the chain, a link in the murderer’s own hand, the one slip he made. You will remember the slip of paper held in Mrs Inglethorp’s hand? That slip of paper has been found. For on the morning of the tragedy the murderer entered the dead woman’s room and forced the lock of the despatch case. Its importance can be guessed at from the immense risks the murderer took. There was one risk he did not take – and that was the risk of keeping it on his own person – he had no time or opportunity to destroy it. There was only one thing left for him to do.’
‘What was that?’
‘To hide it. He did hide it and so cleverly that, though I have searched for two months it is not until today that I found it. Voila, ici le prize.’
With a flourish Poirot drew out three long slips of paper.
‘It has been torn – but it can easily be pieced together. It is a complete and damning proof.19 Had it been a little clearer in its terms it is possible that Mrs Inglethorp would not have died. But as it was, while opening her eyes to who, it left her in the dark as to how. Read it, Mr Le Juge. For it is an unfinished letter from the murderer, Alfred Inglethorp, to his lover and accomplice, Evelyn Howard.’
And there, like Alfred Inglethorp’s pieced-together letter at the end of Chapter 12, Notebook 37 breaks off, despite the fact that the following pages are blank. We know from the published version that Alfred Inglethorp and Evelyn Howard are subsequently arrested for the murder, John and Mary Cavendish are reconciled, Cynthia and Lawrence announce their engagement, while Dr Bauerstein is shown to be more interested in spying than in poisoning. The book closes with Poirot’s hope that this investigation will not be his last with ‘mon ami’ Hastings.
The reviews on publication were as enthusiastic as the pre-publication reports for John Lane. The Times called it ‘a brilliant story’ and the Sunday Times found it ‘very well contrived’. The Daily News considered it ‘a skilful tale and a talented first book’, while the Evening News thought it ‘a wonderful triumph’ and described Christie as ‘a distinguished addition to the list of writers in this [genre]’. ‘Well written, well proportioned and full of surprises’ was the verdict of The British Weekly.
Poirot’s dramatic evidence in the course of the trial resembles a similar scene at the denouement of Leroux’s The Mystery of the Yellow Room (1907) – specifically mentioned in An Autobiography – where the detective, Rouletabille, gives his remarkable and conclusive evidence from the witness box. Had John Lane but known it, in demanding the alteration to the denouement of the novel he unwittingly paved the way for a half century of drawing-room elucidations stage-managed by both Poirot and Miss Marple. And although this explanation, in both courtroom and drawing room, is essentially the same, the unlikelihood of a witness being allowed to give evidence in this manner is self-evident. In other ways also The Mysterious Affair at Styles presaged what was to become typical Christie territory – an extended family, a country house, a poisoning drama, a twisting plot, and a dramatic and unexpected final revelation.
It is not a very extended family, however. Of Mrs Inglethorp’s family, there is a husband, two stepsons, one daughter-in-law, a family friend,
