“Ah!” said Poirot, smiling broadly. “That is the cream of Giraud’s little jest. According to him, it is not a woman’s hair at all. Remember that the youths of today wear their hair brushed straight back from the forehead with pomade or hair wash to make it lie flat. Consequently some of the hairs are of considerable length.”
“And you believe that too?”
“No,” said Poirot, with a curious smile. “For I know it to be the hair of a woman—and more, which woman!”
“Madame Daubreuil,” I announced positively.
“Perhaps,” said Poirot, regarding me quizzically. But I refused to allow myself to get annoyed.
“What are we going to do now?” I asked, as we entered the hall of the Villa Geneviève.
“I wish to make a search among the effects of M. Jack Renauld. That is why I had to get him out of the way for a few hours.”
Neatly and methodically, Poirot opened each drawer in turn, examined the contents, and returned them exactly to their places. It was a singularly dull and uninteresting proceeding. Poirot waded on through collars, pyjamas, and socks. A purring noise outside drew me to the window. Instantly I became galvanized into life.
“Poirot!” I cried. “A car has just driven up. Giraud is in it, and Jack Renauld, and two gendarmes.”
“Sacré tonnerre!” growled Poirot. “That animal of a Giraud, could he not wait? I shall not be able to replace the things in this last drawer with the proper method. Let us be quick.”
Unceremoniously he tumbled out the things on the floor, mostly ties and handkerchiefs. Suddenly with a cry of triumph Poirot pounced on something, a small square of cardboard, evidently a photograph. Thrusting it into his pocket, he returned the things pell-mell to the drawer, and seizing me by the arm dragged me out of the room and down the stairs. In the hall stood Giraud, contemplating his prisoner.
“Good afternoon, Monsieur Giraud,” said Poirot. “What have we here?”
Giraud nodded his head towards Jack.
“He was trying to make a getaway, but I was too sharp for him. He’s under arrest for the murder of his father, Monsieur Paul Renauld.”
Poirot wheeled round to confront the boy, who was leaning limply against the door, his face ashy pale.
“What do you say to that, jeune homme?”
Jack Renauld stared at him stonily.
“Nothing,” he said.

I USE MY GREY CELLS
I was dumbfounded. Up to the last, I had not been able to bring myself to believe Jack Renauld guilty. I had expected a ringing proclamation of his innocence when Poirot challenged him. But now, watching him as he stood, white and limp against the wall, and hearing the damning admission fall from his lips, I doubted no longer.
But Poirot had turned to Giraud.
“What are your grounds for arresting him?”
“Do you expect me to give them to you?”
“As a matter of courtesy, yes.”
Giraud looked at him doubtfully. He was torn between a desire to refuse rudely and the pleasure of triumphing over his adversary.
“You think I have made a mistake, I suppose?” he sneered.
“It would not surprise me,” replied Poirot, with a soupçon of malice.
Giraud’s face took on a deeper tinge of red.
“Eh bien, come in here. You shall judge for yourself.”
He flung open the door of the salon, and we passed in, leaving Jack Renauld in the care of the two other men.
“Now, Monsieur Poirot,” said Giraud, laying his hat on the table, and speaking with the utmost sarcasm, “I will treat you to a little lecture on detective work. I will show how we moderns work.”
“Bien!” said Poirot, composing himself to listen. “I will show you how admirably the Old Guard can listen.” And he leaned back and closed his eyes, opening them for a moment to remark: “Do not fear that I shall sleep. I will attend most carefully.”
“Of course,” began Giraud, “I soon saw through all that Chilean tomfoolery. Two men were in it—but they were not mysterious foreigners! All that was a blind.”
“Very creditable so far, my dear Giraud,” murmured Poirot. “Especially after that clever trick of theirs with the match and cigarette end.”
Giraud glared, but continued.
“A man must have been connected with the case, in order to dig the grave. There is no man who actually benefits by the crime, but there was a man who thought he would benefit. I heard of Jack Renauld’s quarrel with his father, and of the threats that he had used. The motive was established. Now as to means. Jack Renauld was in Merlinville that night. He concealed the fact—which turned suspicion into certainty. Then we found a second victim—stabbed with the same dagger. We know when that dagger was stolen. Captain Hastings here can fix the time. Jack Renauld, arriving from Cherbourg, was the only person who could have taken it. I have accounted for all the other members of the household.”
Poirot interrupted.
“You are wrong. There is one other person who could have taken the dagger.”
“You refer to Monsieur Stonor? He arrived at the front door, in an automobile which had brought him straight from Calais. Ah! believe me, I have looked into everything. Monsieur Jack Renauld arrived by train. An hour elapsed between his arrival and the moment when he presented himself at the house. Without doubt, he saw Captain Hastings and his companion leave the shed, slipped in himself and took the dagger, stabbed his accomplice in the shed—”
“Who was already dead!”
Giraud shrugged his shoulders.
“Possibly he did not observe that. He may have judged him to be sleeping. Without doubt they had a rendezvous. In any case he knew this apparent second murder would greatly complicate the case. It did.”
“But it could not deceive Monsieur Giraud,” murmured Poirot.
“You mock at me! But I will give you one last irrefutable proof. Madame Renauld’s story was false—a fabrication from beginning to end. We believe Madame Renauld to have loved her husband—yet she lied to shield his murderer. For whom will a woman lie? Sometimes for herself, usually for the man she loves, always for her children. That is the last—the irrefutable proof. You cannot get round it.”
Giraud paused, flushed and triumphant. Poirot regarded him steadily.
“That is my case,” said Giraud. “What have you to say to it?”
“Only that there is one thing you have failed to take into account.”
“What is that?”
“Jack Renauld was presumably acquainted with the planning out of the golf course. He knew that the body would be discovered almost at once, when they started to dig the bunker.”
Giraud laughed out loud.
“But it is idiotic what you say there! He wanted the body to be found! Until it was found, he could not presume death, and would have been unable to enter into his inheritance.”
I saw a quick flash of green in Poirot’s eyes as he rose to his feet.
“Then why bury it?” he asked very softly. “Reflect, Giraud. Since it was to Jack Renauld’s advantage that the body should be found without delay, why dig a grave at all?”
Giraud did not reply. The question found him unprepared. He shrugged his shoulders as though to intimate that it was of no importance.
Poirot moved towards the door. I followed him.
“There is one more thing that you have failed to take into account,” he said over his shoulder.
“What is that?”
“The piece of lead piping,” said Poirot, and left the room.
Jack Renauld still stood in the hall, with a white dumb face, but as we came out of the salon he looked up sharply. At the same moment there was the sound of a footfall on the staircase. Mrs. Renauld was descending it. At the sight of her son, standing between the two myrmidons of the law, she stopped as though petrified.
“Jack,” she faltered. “Jack, what is this?”
He looked up at her, his face set.
“They have arrested me, mother.”
“What?”
She uttered a piercing cry, and before anyone could get to her, swayed, and fell heavily. We both ran to her and lifted her up. In a minute Poirot stood up again.
“She has cut her head badly, on the corner of the stairs. I fancy there is slight concussion also. If Giraud wants a statement from her, he will have to wait. She will probably be unconscious for at least a week.”
Denise and Françoise had run to their mistress, and leaving her in their charge Poirot left the house. He walked with his head down, frowning thoughtfully. For some time I did not speak, but at last I ventured to put a question to him:
“Do you believe then, in spite of all appearances to the contrary, that Jack Renauld may not be guilty?”
Poirot did not answer at once, but after a long wait he said gravely:
“I do not know, Hastings. There is just a chance of it. Of course Giraud is all wrong—wrong from beginning to end. If Jack Renauld is guilty, it is in spite of Giraud’s arguments, not because of them. And the gravest indictment against him is known only to me.”
“What is that?” I asked, impressed.
“If you would use your grey cells, and see the whole case clearly as I do, you too would perceive it, my friend.”
