“What are you doing here, eh?”

It was the first time that he had shown surprise at the presence of a stranger beside him.

Gradually, in this way, he recovered all his faculties. He talked. He made plans. But, when Beautrelet asked him about the events immediately preceding his sleep, he seemed not to understand.

And Beautrelet felt that he really did not understand. He had lost the recollection of all that had happened since the Friday before. It was like a sudden gap in the ordinary flow of his life. He described his morning and afternoon on the Friday, the purchases he had made at the fair, the meals he had taken at the inn. Then—nothing—nothing more. He believed himself to be waking on the morrow of that day.

It was horrible for Beautrelet. The truth lay there, in those eyes which had seen the walls of the park behind which his father was waiting for him, in those hands which had picked up the letter, in that muddled brain which had recorded the whereabouts of that scene, the setting, the little corner of the world in which the play had been enacted. And from those hands, from that brain he was unable to extract the faintest echo of the truth so near at hand!

Oh, that impalpable and formidable obstacle, against which all his efforts hurled themselves in vain, that obstacle built up of silence and oblivion! How clearly it bore the mark of Arsène Lupin! He alone, informed, no doubt, that M. Beautrelet had attempted to give a signal, he alone could have struck with partial death the one man whose evidence could injure him. It was not that Beautrelet felt himself to be discovered or thought that Lupin, hearing of his stealthy attack and knowing that a letter had reached him, was defending himself against him personally. But what an amount of foresight and real intelligence it displayed to suppress any possible accusation on the part of that chance wayfarer! Nobody now knew that within the walls of a park there lay a prisoner asking for help.

Nobody? Yes, Beautrelet. Gaffer Charel was unable to speak. Very well. But, at least, one could find out which fair the old man had visited and which was the logical road that he had taken to return by. And, along this road, perhaps it would at last be possible to find—

Isidore, as it was, had been careful not to visit Gaffer Charel’s hovel except with the greatest precautions and in such a way as not to give an alarm. He now decided not to go back to it. He made inquiries and learnt that Friday was market-day at Fresselines, a fair-sized town situated a few leagues off, which could be reached either by the rather winding highroad or by a series of short cuts.

On the Friday, he chose the road and saw nothing that attracted his attention, no high walled enclosure, no semblance of an old castle.

He lunched at an inn at Fresselines and was on the point of leaving when he saw Gaffer Charel arrive and cross the square, wheeling his little knife-grinding barrow before him. He at once followed him at a good distance.
