'At once. We will command an auto.'
Half an hour later saw us at the Villa Marguerite. Marthe was at the door to meet us, and let Poirot in, clinging with both hands to one of his.
'Ah, you have come-it is good of you. I have been in despair, not knowing what to do. They will not let me go to see him in prison even. I suffer horribly. I am nearly mad. Is it true what they say, that he does not deny the crime?'
'But that is madness. It is impossible that he should have done it! Never for one minute will I believe it.'
'Neither do I believe it, mademoiselle,' said Poirot gently.
'But then why does he not speak? I do not understand.'
'Perhaps because he is screening someone,' suggested Poirot, watching her.
Marthe frowned.
'Screening someone? Do you mean his mother? Ah, from the beginning I have suspected her. Who inherits all that vast fortune? She does. It is easy to wear widow's weeds and play the hypocrite. And they say that when he was arrested she fell down like that!' She made a dramatic gesture. 'And without doubt, Monsieur Stonor, the secretary, he helped her. They are thick as thieves, those two. It is true she is older than he-but what do men care-if a woman is rich?'
There was a hint of bitterness in her tone.
'Stonor was in England,' I put in.
'He says so-but who knows?'
'Mademoiselle,' said Poirot quietly, 'if we are to work together, you and I, we must have things clear. First, I will ask you a question.'
'Yes, monsieur?'
'Are you aware of your mother's real name?'
Marthe looked at him for a minute, then, letting her head fall forward on her arms, she burst into tears.
'There, there,' said Poirot, patting her on the shoulder. 'Calm yourself. I see that you know. Now a second question-did you know who Monsieur Renauld was?'
'Monsieur Renauld,' she raised her head from her hands and looked at him wonderingly.
'Ah, I see you do not know that. Now listen to me carefully.'
Step by step, he went over the case, much as he had done to me on the day of our departure for England. Marthe listen spellbound. When he had finished, she drew a long breath.
'But you are wonderful-magnificent! You are the greatest detective in the world.'
With a swift gesture she slipped off her chair and knelt before him with an abandonment that was wholly French.
'Save him, monsieur,' she cried. 'I love him so. Oh, save him: save him-save him!'
Chapter 25. An Unexpected Dénouement
WE were present the following morning at the examination of Jack Renauld. Short as the time had been, I was shocked at the change that had taken place in the young prisoner.
His cheeks had fallen in, there were deep black circles round his eyes, and he looked haggard and distraught, as one who had wooed sleep in vain for several nights. He betrayed no emotion at seeing us.
'Renauld,' began the magistrate 'do you deny that you were in Merlinville on the night of the crime?'
Jack did not reply at once, then he said with a hesitancy of manner which was piteous: 'I-I-told you that I was in Cherbourg.'
The magistrate turned sharply. 'Send in the station witnesses.'
In a moment or two the door opened to admit a man whom I recognized as being a porter at Merlinville station.
'You were on duty on the night of 7th June?'
'Yes monsieur.'
'You witnessed the arrival of the 11.40 train?'
'Yes, monsieur.'
'Look at the prisoner. Do you recognize him as having been one of the passengers to alight?'
'Yes monsieur.'
'There is no possibility of your being mistaken?'
'No, monsieur. I know Monsieur Jack Renauld well.'
'Nor of your being misled as to the date?'
'No, monsieur. Because it was the following morning, 8thJune, that we heard of the murder.'
Another railway man was brought in, and confirmed the first one's evidence. The magistrate looked at Jack Renauld.
'These men have identified you positively. What have you to say?'
Jack shrugged his shoulders. 'Nothing.'
'Renauld,' continued the magistrate, 'do you recognize this?'
He took something from the table by his side and held it out to the prisoner. I shuddered as I recognized the aeroplane dagger.
'Pardon,' cried Jack's counsel, Maitre Grosier. 'I demand to speak to my client before he answers that question.'
But Jack Renauld had no consideration for the feelings of the wretched Grosier. He waved him aside, and replied quietly: 'Certainly I recognize it. It was a present given by me to my mother, as a souvenir of the war.'
'Is there, as far as you know, any duplicate of that dagger in existence?'
Again Maitre Grosier burst out, and again Jack overrode him.
'Not that I know of. The setting was my own design.'
Even the magistrate almost gasped at the boldness of the reply. It did, in very truth, seem as though Jack was rushing on his fate. I realized, of course, the vital necessity he was under of concealing, for Bella's sake, the fact that there was a duplicate dagger in the case. So long as there was supposed to be only one weapon, no suspicion was likely to attach to the girl who had had the second paper knife in her possession.
He was valiantly shielding the woman he had once loved-but at what cost to himself! I began to realize the magnitude of the task I had so lightly set Poirot. It would not be easy to secure the acquittal of Jack Renauld by anything short of the truth.
M. Hautet spoke again with a peculiarly biting inflection: 'Madame Renauld told us that this dagger was on her dressing table on the night of the crime. But Madame Renauld is a mother! It will doubtless astonish you, Renauld, but I consider it highly likely that Madame Renauld was mistaken, and that, by inadvertence perhaps, you had taken it with you to Paris. Doubtless you will contradict me.'
I saw the lad's handcuffed hands clench themselves. The perspiration stood out in beads upon his brow as with a supreme effort he interrupted M. Hautet in a hoarse voice: 'I shall not contradict you. It is possible.'
It was a stupefying moment. Maitre Grosier rose to his feet protesting: 'My client has undergone a considerable nervous strain. I should wish it put on record that I do not consider him answerable for what he says.'
The magistrate quelled him angrily. For a moment a doubt seemed to arise in his own mind. Jack Renauld had almost overdone his part. He leaned forward, and gazed at the prisoner searchingly.
'Do you fully understand, Renauld, that on the answers you have given me I shall have no alternative but to commit you for trial?'
Jack's pale face flushed. He looked steadily back. 'Monsieur Hautet, I swear that I did not kill my father.'
But the magistrate's brief moment of doubt was over. He laughed a short unpleasant laugh. 'Without doubt, without doubt-they are always innocent, our prisoners! By your own mouth you are condemned. You can offer no defence, no alibi-only a mere assertion which would not deceive a babe!-that you are not guilty. You killed your father, Renauld-a evil and cowardly murder-for the sake, of the money which you believed would come to you at his death. Your mother was an accessory after the fact. Doubtless, in view of the fact that she acted as a mother, the
