A doctor was soon procured. After examining the patient, he gave it as his opinion that it was simply a case of nerve strain. With perfect rest and quiet the lad might be almost restored by the next day, but, if excited, there was a chance of brain fever. It would be advisable for someone to sit up all night with him.
Finally, having done all we could we left him in the charge of Marthe and her mother, and set out for the town.
It was past our usual hour of dining, and we were both famished.
The first restaurant we came to assuaged the pangs of hunger with an excellent omelette and an equally excellent entree to follow.
'And now for quarters for the night.' Said Poirot, when at length we had completed the meal. 'Shall we try our old friend, the Hotel des Bains?'
We traced our steps there without more ado. Yes, Messieurs could be accommodated with two good rooms overlooking the sea. Then Poirot asked a question which surprised me: 'Has an English lady, Miss Robinson, arrived?'
'Yes, monsieur. She is in the little salon.'
'Ah!'
'Poirot,' I cried, keeping pace with him, as he walked along the corridor, 'who on earth is Miss Robinson?'
Poirot beamed kindly on me. 'It is that I have arranged you a marriage, Hastings.'
'But I say-'
'Bah!' said Poirot, giving me a friendly push over the threshold of the door. 'Do you think I wish to trumpet aloud in Merlinville the name of Duveen?'
It was indeed Cinderella who rose to greet us. I took her hand in both of mine. My eyes said the rest.
Poirot cleared his throat.
'Mes enfants,' he said, 'for the moment we have no time for sentiment. There is work ahead of us. Mademoiselle, were you able to do what I asked you?'
In response, Cinderella took from her bag an object wrapped up in paper, and handed it silently to Poirot. The latter unwrapped it. I gave a start-for it was the aeroplane dagger which I understood she had cast into the sea. Strange, how reluctant women always are to destroy the most compromising of objects and documents!
'Tres bien, mon enfant,' said Poirot. 'I am pleased with you. Go now and rest yourself. Hastings here and I have work to do. You shall see him tomorrow.'
'Where are you going?' asked the girl, her eyes widening.
'You shall hear all about it tomorrow.'
'Because wherever you're going, I'm coming too.'
'But, mademoiselle-'
'I'm coming too, I tell you.'
Poirot realized that it was futile to argue. He gave in. 'Come then, mademoiselle. But it will not be amusing. In all probability nothing will happen.'
The girl made no reply.
Twenty minutes later we set forth. It was quite dark now, a close oppressive evening. Poirot led the way out of the town in the direction of the Villa Genevieve. But when he reached the Villa Marguerite he paused.
'I should like to assure myself that all goes well with Jack Renauld. Come with me, Hastings. Mademoiselle will perhaps remain outside. Madame Daubreuil might say something which would wound her.'
We unlatched the gate, and walked up the path. As we went round to the side of the house, I drew Poirot's attention to a window on the first floor. Thrown sharply on the blind was the profile of Marthe Daubreuil.
'Ah!' said Poirot. 'I figure to myself that that is the room where we shall find Jack Renauld.'
Madame Daubreuil opened the door to us. She explained that Jack was much the same but perhaps we would like to see for ourselves. She led us upstairs and into the bedroom.
Marthe Daubreuil was sitting by a table with a lamp on it, working. She put her finger to her lips as we entered.
Jack Renauld was sleeping an uneasy, fitful sleep, his head turning from side to side and his face still unduly flushed.
'Is the doctor coming again?' asked Poirot in a whisper.
'Not unless we send. He is sleeping-that is the great thing. Maman made him a tisane.'
She sat down again with her embroidery as we left the room. Madame Daubreuil accompanied us down the stairs.
Since I had learned of her past history, I viewed this woman with increased interest. She stood there with her eyes cast down, the same very faint, enigmatical smile that I remembered on her lips. And suddenly I felt afraid of her, as one might feel afraid of a beautiful poisonous snake.
'I hope we have not deranged you, madame,' said Poirot politely, as she opened the door for us to pass out.
'Not at all, monsieur.'
'By the way,' said Poirot, as though struck by an afterthought, 'Monsieur Stonor has not been in Merlinville today, has he?'
I could not at all fathom the point of this question, which I well knew to be meaningless as far as Poirot was concerned.
Madame Daubreuil replied quite composedly: 'Not that I know of.'
'He has not had an interview with Madame Renauld?'
'How should I know that, monsieur?'
'True,' said Poirot. 'I thought you might have seen him coming or going, that is all. Goodnight, madame.'
'Why-' I began.
'No whys, Hastings. There will be time for that later.'
