Poirot has a bee in his bonnet.
He thinks he has seen Mme Daubreuil before, but not for real. He has the idea that he saw her in a picture when he was working with the Belgian police in a case, and he has the hunch that it was a murder case. So does this mean that Mme Daubreuil was involved in some murder and got away with it?
Hastings runs into the woman he met on the train, the one she said her name was Cinderella. It is clear that Hastings’s weakness is pretty women, and he becomes putter in their hands. Cinderella persuades him to show him the scene crime and even the shed where Arnauld’s body is still kept. When she is in the shed, she feels faint, and Hastings goes to the house for water. I have the hunch that it was all pretence, and Cinderella has probably stolen the paperknife which killed Mr Arnauld. I wonder who she is and what links her to the murder.
Apart from that, Giraud has found a cigarette and a burnt match in the crime scene, claiming that this is an important clue. It tells us that one of the murderers smoked South American cigarettes. Poirot takes this new evidence with a pinch a salt as he thinks that this is not so vital for the investigation or even doubting the source of the items. He believes there is some other evidence which is more revealing like Mrs Arnauld’s watch which was two hours fast, the lack of footprints on the flowerbed, and he also mentions why the murderers left the door ajar when they left.
Now Jack Renauld returns after learning about the tragic news in a newspaper. Poirot and the others interview him. Leonie, one of the maids, told Poirot that she had heard Mr Renauld and his son quarrel violently, and this is what Jack is most asked about. Poirot guesses that the reason why father and son argued was that Jack is in love with Marthe Daubreuil, and his father opposed to their liaison. Jack went as far as to say that he wished his father were dead so that he could do what he wanted. Then he left for Paris, and it seems that it is then that Mr Renauld changed his will in favour of his wife and leaving his son out of it. The secretary previously revealed that Mr Renauld was loyal to his wife and he couldn’t believe Mme Daubreil could be his mistress, so he thinks that the reason why Mr Renauld was seeing Mme Daubreuil might be that the woman was blackmailing him. However, Mrs Renauld concedes that maybe Mme Daubreuil was her husband’s mistress. I wonder which one is true. The thing is that Mr Renauld didn’t want her son to get involved with Marthe. Was it because her mother was his lover or because she was blackmailing her?
The story is really convoluted, and I only have a slight idea of what the truth might be. I have a vague memory of when I first read the novel, and I think it had to do with some kind of deceit from the Renaulds going wrong. Yet, I don’t remember much more. I have no idea who Cinderella is and how she is linked to the case, and why Mr Renauld saw Mme Daubreuil every night.
