"Yes. You told me that you walked up to the hotel with Harry Wethermill on the night of the murder and separated just before ten. A glance into his rooms which I had--you will remember that when we had discovered the motor-car I suggested that we should go to Harry Wethermill's rooms and talk it over--that glance enabled me to see that he could very easily have got out of his room on to the verandah below and escaped from the hotel by the garden quite unseen. For you will remember that whereas your rooms look out to the front and on to the slope of Mont Revard, Wethermill's look out over the garden and the town of Aix. In a quarter of an hour or twenty minutes he could have reached the Villa Rose. He could have been in the salon before half-past ten, and that is just the hour which suited me perfectly. And, as he got out unnoticed, so he could return. So he did return! My friend, there are some interesting marks upon the window-sill of Wethermill's room and upon the pillar just beneath it. Take a look, M. Ricardo, when you return to your hotel. But that was not all. We talked of Geneva in Mr. Wethermill's room, and of the distance between Geneva and Aix. Do you remember that?" "Yes," replied Ricardo. "Do you remember too that I asked him for a road-book?" "Yes; to make sure of the distance. I do." "Ah, but it was not to make sure of the distance that I asked for the road-book, my friend. I asked in order to find out whether Harry Wethermill had a road-book at all which gave a plan of the roads between here and Geneva. And he had. He handed it to me at once and quite naturally. I hope that I took it calmly, but I was not at all calm inside. For it was a new road-book, which, by the way, he bought a week before, and I was asking myself all the while--now what was I asking myself, M. Ricardo?" "No," said Ricardo, with a smile. "I am growing wary. I will not tell you what you were asking yourself, M. Hanaud. For even were I right you would make out that I was wrong, and leap upon me with injuries and gibes. No, you shall drink your coffee and tell me of your own accord."
