“She has cut her head badly, on the corner of the stairs. I fancy there is a 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 bent down, frowning thoughtfully at the ground. 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.”
This was what I called one of Poirot’s irritating answers. He went on, without waiting for me to speak.
“Let us walk this way to the sea. We will sit on that little mound there, overlooking the beach, and review the case. You shall know all that I know, but I would prefer that you should come at the truth by your own efforts—not by my leading you by the hand.”
We established ourselves on the grassy knoll as Poirot had suggested, looking out to sea. From farther along the sand, the cries of the bathers reached us faintly. The sea was of the palest blue, and the halcyon calm reminded me of the day we had arrived at Merlinville, my own good spirits, and Poirot’s suggestion that I was “fey.” What a long time seemed to have elapsed since then. And in reality it was only three days!
