‘Monsieur Jack Renauld.’
‘What?’ It was a cry. ‘Jack? Impossible. Who dares to suspect him?’
‘Giraud.’
‘Giraud!’ The girl’s face was ashy. ‘I am afraid of that man. He is cruel. He will—he will—’ She broke off. There was courage gathering in her face and determination. I realized in that moment that she was a fighter. Poirot too, watched her intently.
‘You know, of course, that he was here on the night of the murder?’ he asked.
‘Yes,’ she replied mechanically. ‘He told me.’
‘It was unwise to have tried to conceal the fact,’ ventured Poirot.
‘Yes, yes,’ she replied impatiently. ‘But we cannot waste time on regrets. We must find something to save him. He is innocent, of course; but that will not help him with a man like Giraud, who has his reputation to think of. He must arrest someone, and that someone will be Jack.’
‘The facts will tell against him,’ said Poirot. ‘You realize that?’
She faced him squarely. ‘I am not a child, monsieur. I can be brave and look facts in the face. He is innocent, and we must save him.’
She spoke with a kind of desperate energy, then was silent, frowning as she thought.
‘Mademoiselle’ said Poirot, observing her keenly, ‘is there not something that you are keeping back that you could tell us?’
She nodded perplexedly. ‘Yes, there is something, but I hardly know whether you will believe it—it seems so absurd.’
‘At any rate, tell us, mademoiselle.’
‘It is this. M. Giraud sent for me, as an afterthought, to see if I could identify the man in there.’ She signed with her head towards the shed. ‘I could not. At least I could not at the moment. But since I have been thinking—’
‘Well?’
‘It seems so queer, and yet I am almost sure. I will tell you. On the morning of the day Monsieur Renauld was murdered, I was walking in the garden here, when I heard a sound of men’s voices quarrelling. I pushed aside the bushes and looked through. One of the men was Monsieur Renauld and the other was a tramp, a dreadful-looking creature in filthy rags. He was alternately whining and threatening. I gathered he was asking for money, but at that moment maman called me from the house, and I had to go. That is all, only—I am almost sure that the tramp and the dead man in the shed are one and the same.’
Poirot uttered an exclamation. ‘But why did you not say so at the time, mademoiselle?’
‘Because at first it only struck me that the face was vaguely familiar in some way. The man was differently dressed, and apparently belonged to a superior station in life.’
A voice called from the house.
‘Maman,’ whispered Marthe: ‘I must go.’ And she slipped away through the trees.
‘Come,’ said Poirot, and taking my arm turned in the direction of the villa.
‘What do you really think?’ I asked in some curiosity.
‘Was that story true, or did the girl make it up in order to divert suspicion from her lover?’
‘It is a curious tale,’ said Poirot, ‘but I believe it to be the absolute truth. Unwittingly, Mademoiselle Marthe told us the truth on another point—and incidentally gave Jack Renauld the lie. Did you notice his hesitation when I asked him if he saw Marthe Daubreuil on the night of the crime?’
He paused and then said ‘Yes. I suspected that he was lying. It was necessary for me to see Mademoiselle Marthe before he could put her on her guard. Three little words gave me the information I wanted. When I asked her if she knew that Jack Renauld was here that night, she answered, “He told me”. Now, Hastings, what was Jack Renauld doing here on that eventful evening, and if he did not see Mademoiselle Marthe whom did he see?’
‘Surely, Poirot,’ I cried, aghast, ‘you cannot believe that a boy like that would murder his own father!’
‘Mon ami,’ said Poirot. ‘You continue to be of a sentimentality unbelievable! I have seen mothers who murdered their little children for the sake of the insurance money! After that, one can believe anything.’
