So I went forth across the bridge to a big café opposite the theatre, and there idled till nearly midnight, when I returned eagerly to meet my friend. He entered my room just before one o'clock in the morning, tired and dusty, for he appeared to have walked a long distance. I had some cognac and a syphon of seltzer awaiting him, and sinking exhausted into a chair, he took a long and refreshing drink before he spoke. "Well?" he said with a sigh. "You have been wondering why I disappeared so mysteriously--eh? The fact is I was compelled. On making inquiry of a shoemaker who has a little shop near Charles Rabel's house I learned that the man for whom we are searching lived in a flat on the first floor of the house kept by a widow named Cailliot. But he was frequently absent in England or in Italy. Only for short spells was he there, for he was a commercial traveller representing a Lyons firm of silkweavers. As we were speaking, the shoemaker pointed to a rather smart young woman who was at that moment leaving the house, and said: 'Look! That is Mademoiselle Jacquelot, the fiancée of Monsieur Charles! She might tell you where he is. I do not think he is at home to-day. I saw him four days ago and spoke to him as he passed. But I believe he has left again!' I thanked him, and at once followed Mademoiselle, hence I had no time to tell you, for I had no idea where she was going. I saw that by following Rabel's fiancée I might gain some useful knowledge. She walked to the station, and took a ticket for Castelsarrasin. I did the same. We had half an hour to wait, but I spent it patiently, and when we left I travelled alone with her in the same compartment. Soon I managed to get into conversation with her, whereupon I mentioned that I had a friend, Monsieur Charles Rabel, in Montauban, and that we had met in Paris. He had once shown me her photograph and I believed I was not mistaken that she was Mademoiselle Jacquelot. At first she was surprised, but I told her a very plausible story, whereupon she explained that Charles had gone to Toulouse on business three days before, but that he was returning at noon to-morrow. She herself lived in Castelsarrasin." "But do you anticipate that we shall discover in Charles Rabel the notorious Despujol?" I inquired eagerly. Rivero raised his shoulders and elevated his black eyebrows, saying: "From facts I gathered from Mademoiselle concerning him I certainly think that we are really upon his track. It hardly seems possible, but we must remain in patience till to-morrow. Then, if we find our surmise correct, we must act with the greatest caution if we are to watch him to Nîmes where he is to meet your mysterious friend--the man whose name you refuse to reveal." "When they meet you will at once recognize him," I said. "I may be mistaken," I added. "But I do not anticipate that I am. If all goes well, then you will arrest the notorious Despujol."
