not likely to use the car, and that Masters might just as well take a holiday.
A perplexed frown was beginning to gather between Poirotâs eyes.
âWhat is it?â I whispered.
He shook his head impatiently, and asked a question:
âPardon, Monsieur Bex, but without doubt Monsieur Renauld could drive the car himself?â
The commissary looked over at Françoise, and the old woman replied promptly:
âNo, Monsieur did not drive himself.â
Poirotâs frown deepened.
âI wish you would tell me what is worrying you,â I said impatiently.
âSee you not? In his letter Monsieur Renauld speaks of sending the car for me to Calais.â
âPerhaps he meant a hired car,â I suggested.
âDoubtless, that is so. But why hire a car when you have one of your own? Why choose yesterday to send away the chauffeur on a holidayâsuddenly, at a momentâs notice? Was it that for some reason he wanted him out of the way before we arrived?â

F rançoise had left the room. The magistrate was drumming thoughtfully on the table.
âMonsieur Bex,â he said at length, âhere we have directly conflicting testimony. Which are we to believe, Françoise or Denise?â
âDenise,â said the commissary decidedly. âIt was she who let the visitor in. Françoise is old and obstinate, and has evidently taken a dislike to Madame Daubreuil. Besides, our own knowledge tends to show that Renauld was entangled with another woman.â
âTiens!â cried M. Hautet. âWe have forgotten to inform Monsieur Poirot of that.â He searched among the papers on the table, and finally handed the one he was in search of to my friend. âThis letter, Monsieur Poirot, we found in the pocket of the dead manâs overcoat.â
Poirot took it and unfolded it. It was somewhat worn and crumpled, and was written in English in a rather unformed hand:
My Dearest One,âWhy have you not written for so long? You do love me still, donât you? Your letters lately have been so different, cold, and strange, and now this long silence. It makes me afraid. If you were to stop loving me! But thatâs impossibleâwhat a silly kid I amâalways imagining things! But if you did stop loving me, I donât know what I should doâkill myself perhaps! I couldnât live without you. Sometimes I fancy another woman is coming between us. Let her look out, thatâs allâand you too! Iâd as soon kill you as let her have you! I mean it.
But there, Iâm writing high-flown nonsense. You love me, and I love youâyes, love you, love you, love you!
Your own adoring
Bella.
There was no address or date. Poirot handed it back with a grave face.
âAnd the assumption isâ?â
The examining magistrate shrugged his shoulders.
âObviously Monsieur Renauld was entangled with this EnglishwomanâBella! He comes over here, meets Madame Daubreuil, and starts an intrigue with her. He cools off to the other, and she instantly suspects something. This letter contains a distinct threat. Monsieur Poirot, at first sight the case seemed simplicity itself. Jealousy! The fact that Monsieur Renauld was stabbed in the back seemed to point distinctly to its being a womanâs crime.â
Poirot nodded.
âThe stab in the back, yesâbut not the grave! That was laborious work, hard workâno woman dug that grave, Monsieur. That was a manâs doing.â
The commissary exclaimed excitedly:
âYes, yes, you are right. We did not think of that.â
âAs I said,â continued M. Hautet, âat first sight the case seemed simple, but the masked men, and the letter you received from Monsieur Renauld, complicate matters. Here we seem to have an entirely different set of circumstances, with no relationship between the two. As regards the letter written to yourself, do you
