We had arrived at the steps which led up to the front door of the villa. In the hall another sergent de ville was sitting. He rose at sight of the commissary.
“Where is Monsieur Hautet now?” inquired the latter.
“In the salon, monsieur.”
M. Bex opened a door to the left of the hall, and we passed in. M. Hautet and his clerk were sitting at a big round table. They looked up as we entered. The commissary introduced us, and explained our presence.
M. Hautet, the Juge d’Instruction, was a tall gaunt man, with piercing dark eyes, and a neatly cut grey beard, which he had a habit of caressing as he talked. Standing by the mantelpiece was an elderly man, with slightly stooping shoulders, who was introduced to us as Dr. Durand.
“Most extraordinary,” remarked M. Hautet as the commissary finished speaking. “You have the letter here, monsieur?”
Poirot handed it to him, and the magistrate read it.
“H’m! He speaks of a secret. What a pity he was not more explicit. We are much indebted to you, Monsieur Poirot. I hope you will do us the honour of assisting us in our investigations. Or are you obliged to return to London?”
“Monsieur le juge, I propose to remain. I did not arrive in time to prevent my client’s death, but I feel myself bound in honour to discover the assassin.”
The magistrate bowed.
“These sentiments do you honour. Also, without doubt, Madame Renauld will wish to retain your services. We are expecting M. Giraud from the Sûreté in Paris any moment, and I am sure that you and he will be able to give each other mutual assistance in your investigations. In the meantime, I hope that you will do me the honour to be present at my interrogations, and I need hardly say that if there is any assistance you require it is at your disposal.”
“I thank you, monsieur. You will comprehend that at present I am completely in the dark. I know nothing whatever.”
M. Hautet nodded to the commissary, and the latter took up the tale:
“This morning, the old servant Françoise, on descending to start her work, found the front door ajar. Feeling a momentary alarm as to burglars, she looked into the dining room, but seeing the silver was safe she thought no more about it, concluding that her master had, without doubt, risen early, and gone for a stroll.”
“Pardon, monsieur, for interrupting, but was that a common practice of his?”
“No, it was not, but old Françoise has the common idea as regards the English — that they are mad, and liable to do the most unaccountable things at any moment! Going to call her mistress as usual, a young maid, Léonie, was horrified to discover her gagged and bound, and almost at the same moment news was brought that Monsieur Renauld’s body had been discovered, stone dead, stabbed in the back.”
“Where?”
“That is one of the most extraordinary features of the case. Monsieur Poirot, the body was lying face downwards, in an open grave.”
“What?”
“Yes. The pit was freshly dug — just a few yards outside the boundary of the villa grounds.”
“And it had been dead — how long?”
Dr. Durand answered this.
“I examined the body this morning at ten o’clock. Death must have taken place at least seven, and possibly ten hours previously.”
“H’m! that fixes it at between midnight and 3 a.m.”
“Exactly, and Mrs. Renauld’s evidence places it at after 2 a.m., which narrows the field still farther. Death must have been instantaneous, and naturally could not have been self-inflicted.”
Poirot nodded, and the commissary resumed:
“Madame Renauld was hastily freed from the cords that bound her by the horrified servants. She was in a terrible condition of weakness, almost unconscious from the pain of her bonds. It appears that two masked men entered the bedroom, gagged and bound her, while forcibly abducting her husband. This we know at second hand from the servants. On hearing the tragic news, she fell at once into an alarming state of agitation. On arrival, Dr. Durand immediately prescribed a sedative, and we have not yet been able to question her. But without doubt she will awake more calm, and be equal to bearing the strain of the interrogation.”
The commissary paused.
“And the inmates of the house, monsieur?”
“There is old Françoise, the housekeeper, she lived for many years with the former owners of the Villa Geneviève. Then there are two young girls, sisters, Denise and Léonie Oulard. Their home is in Merlinville, and they come of most respectable parents. Then there is the chauffeur whom Monsieur Renauld brought over from England with him, but he is away on a holiday. Finally there are Madame Renauld and her son, Monsieur Jack Renauld. He, too, is away from home at present.”
Poirot bowed his head. M. Hautet spoke:
“Marchaud!”
The sergent de ville appeared.
“Bring in the woman Françoise.”
The man saluted, and disappeared. In a moment or two he returned, escorting the frightened Françoise.
“Your name is Françoise Arrichet?”
“Yes, monsieur.”
“You have been a long time in service at the Villa Geneviève?”
“Eleven years with Madame la Vicomtesse. Then when she sold the Villa this spring, I consented to remain on with the English milor’. Never did I imagine — ”
The magistrate cut her short.
“Without doubt, without doubt. Now, Françoise, in this matter of the front door, whose business was it to fasten it at night?”
“Mine, monsieur. Always I saw to it myself.”
“And last night?”
“I fastened it as usual.”
“You are sure of that?”
“I swear it by the blessed saints, monsieur.”
“What time would that be?”
“The same time as usual, half past ten, monsieur.”
“What about the rest of the household, had they gone up to bed?”
“Madame had retired some time before. Denise and Léonie went up with me. Monsieur was still in his study.”
“Then, if anyone unfastened the door afterwards, it must have been Monsieur Renauld himself?”
Françoise shrugged her broad shoulders.
“What should he do that for? With robbers and assassins passing every minute! A nice idea! Monsieur was not an imbecile. It is not as though he had had to let the lady out — ”
The magistrate interrupted sharply:
“The lady? What lady do you mean?”
“Why, the lady who came to see him.”
“Had a lady been to see him that evening?”
“But yes, monsieur — and many other evenings as well.”
“Who was she? Did you know her?”
A rather cunning look spread over the woman’s face.
“How should I know who it was?” she grumbled. “I did not let her in last night.”
“Aha!” roared the
