as to how the crime had been committed, but from what I knew of Mr. Inglethorp I fancied that it would be very hard to find anything to connect him with it. When I arrived at the chateau, I realized at once that it was Mrs. Inglethorp who had burnt the will; and there, by the way, you cannot complain, my friend, for I tried my best to force on you the significance of that bedroom fire in midsummer.”

      “Yes, yes,” I said impatiently. “Go on.”

      “Well, my friend, as I say, my views as to Mr. Inglethorp’s guilt were very much shaken. There was, in fact, so much evidence against him that I was inclined to believe that he had not done it.”

      “When did you change your mind?”

      “When I found that the more efforts I made to clear him, the more efforts he made to get himself arrested. Then, when I discovered that Inglethorp had nothing to do with Mrs. Raikes and that in fact it was John Cavendish who was interested in that quarter, I was quite sure.”

      “But why?”

      “Simply this. If it had been Inglethorp who was carrying on an intrigue with Mrs. Raikes, his silence was perfectly comprehensible. But, when I discovered that it was known all over the village that it was John who was attracted by the farmer’s pretty wife, his silence bore quite a different interpretation. It was nonsense to pretend that he was afraid of the scandal, as no possible scandal could attach to him. This attitude of his gave me furiously to think, and I was slowly forced to the conclusion that Alfred Inglethorp wanted to be arrested. Eh bien! from that moment, I was equally determined that he should not be arrested.”

      “Wait a minute. I don’t see why he wished to be arrested?”

      “Because, mon ami, it is the law of your country that a man once acquitted can never be tried again for the same offence. Aha! but it was clever--his idea! Assuredly, he is a man of method. See here, he knew that in his position he was bound to be suspected, so he conceived the exceedingly clever idea of preparing a lot of manufactured evidence against himself. He wished to be arrested. He would then produce his irreproachable alibi--and, hey presto, he was safe for life!”

      “But I still don’t see how he managed to prove his alibi, and yet go to the chemist’s shop?”

      Poirot stared at me in surprise.

      “Is it possible? My poor friend! You have not yet realized that it was Miss Howard who went to the chemist’s shop?”

      “Miss Howard?”

      “But, certainly. Who else? It was most easy for her. She is of a good height, her voice is deep and manly; moreover, remember, she and Inglethorp are cousins, and there is a distinct resemblance between them, especially in their gait and bearing. It was simplicity itself. They are a clever pair!”

      “I am still a little fogged as to how exactly the bromide business was done,” I remarked.

      “Bon! I will reconstruct for you as far as possible. I am inclined to think that Miss Howard was the master mind in that affair. You remember her once mentioning that her father was a doctor? Possibly she dispensed his medicines for him, or she may have taken the idea from one of the many books lying about when Mademoiselle Cynthia was studying for her exam. Anyway, she was familiar with the fact that the addition of a bromide to a mixture containing strychnine would cause the precipitation of the latter. Probably the idea came to her quite suddenly. Mrs. Inglethorp had a box of bromide powders, which she occasionally took at night. What could be easier than quietly to dissolve one or more of those powders in Mrs. Inglethorp’s large sized bottle of medicine when it came from Coot’s? The risk is practically nil. The tragedy will not take place until nearly a fortnight later. If anyone has seen either of them touching the medicine, they will have forgotten it by that time. Miss Howard will have engineered her quarrel, and departed from the house. The lapse of time, and her absence, will defeat all suspicion. Yes, it was a clever idea! If they had left it alone, it is possible the crime might never have been brought home to them. But they were not satisfied. They tried to be too clever--and that was their undoing.”

      Poirot puffed at his tiny cigarette, his eyes fixed on the ceiling.

      “They arranged a plan to throw suspicion on John Cavendish, by buying strychnine at the village chemist’s, and signing the register in his hand-writing.

      “On Monday Mrs. Inglethorp will take the last dose of her medicine. On Monday, therefore, at six o’clock, Alfred Inglethorp arranges to be seen by a number of people at a spot far removed from the village. Miss Howard has previously made up a cock and bull story about him and Mrs. Raikes to account for his holding his tongue afterwards. At six o’clock, Miss Howard, disguised as Alfred Inglethorp, enters the chemist’s shop, with her story about a dog, obtains the strychnine, and writes the name of Alfred Inglethorp in John’s handwriting, which she had previously studied carefully.

      “But, as it will never do if John, too, can prove an alibi, she writes him an anonymous note--still copying his hand-writing --which takes him to a remote spot where it is exceedingly unlikely that anyone will see him.

      “So far, all goes well. Miss Howard goes back to Middlingham. Alfred Inglethorp returns to Styles. There is nothing that can compromise him in any way, since it is Miss Howard who has the strychnine, which, after all, is only wanted as a blind to throw suspicion on John Cavendish.

      “But now a hitch occurs. Mrs. Inglethorp does not take her medicine that night. The broken bell, Cynthia’s absence-- arranged by Inglethorp through his wife--all these are wasted. And then--he makes his slip.

      “Mrs. Inglethorp is out, and he sits down to write to his accomplice, who, he fears, may be in a panic at the nonsuccess of their plan. It is probable that Mrs. Inglethorp returned earlier than he expected. Caught in the act, and somewhat flurried he hastily shuts and locks his desk. He fears that if he remains in the room he may have to open it again, and that Mrs. Inglethorp might catch sight of the letter before he could snatch it up. So he goes out and walks in the woods, little dreaming that Mrs. Inglethorp will open his desk, and discover the incriminating document.

      “But this, as we know, is what happened. Mrs. Inglethorp reads it, and becomes aware of the perfidy of her husband and Evelyn Howard, though, unfortunately, the sentence about the bromides conveys no warning to her mind. She knows that she is in danger--but is ignorant of where the danger lies. She decides to say nothing to her husband, but sits down and writes to her solicitor, asking him to come on the morrow, and she also determines to destroy immediately the will which she has just made. She keeps the fatal letter.”

      “It was to discover that letter, then, that her husband forced the lock of the despatch-case?”

      “Yes, and from the enormous risk he ran we can see how fully he realized its importance. That letter excepted, there was absolutely nothing to connect him with the crime.”

      “There’s only one thing I can’t make out, why didn’t he destroy it at once when he got hold of it?”

      “Because he did not dare take the biggest risk of all--that of keeping it on his own person.”

      “I don’t understand.”

      “Look at it from his point of view. I have discovered that there were only five short minutes in which he could have taken it--the five minutes immediately before our own arrival on the scene, for before that time Annie was brushing the stairs, and would have seen anyone who passed going to the right wing. Figure to yourself the scene! He enters the room, unlocking the door by means of one of the other doorkeys--they were all much alike. He hurries to the despatch-case--it is locked, and the keys are nowhere to be seen. That is a terrible blow to him, for it means that his presence in the room cannot be concealed as he had hoped. But he sees clearly that everything must be risked for the sake of that damning piece of evidence. Quickly, he forces the lock with a penknife, and turns over the papers until he finds what he is looking for.

      “But
