Again he rose, and during his absence I once more glanced at the formidable dossier concerning the wealthy Jules Cauvin, who was so well known in the gay night life of Paris, whose smart wife was one of the leaders in the social world, and who had recently established a hospital out at Neuilly, where his wife and daughter worked unceasingly on behalf of the wounded. According to one report, the suspected man was in the habit of entertaining certain high officials of the State at his fine house close to the Etoile, and he had several bosom friends in the Admiralty. Such was the present position of a man who only five years ago was a struggling corn-merchant in rural Auvergne. I lit a cigarette and reflected. By the time Hecq had returned I had hit upon the rough outlines of a plan. "First of all," I said, "you must call off the surveillance on Cauvin. I must have a free hand in the affair, and the Surete must not interfere in any way. If Cauvin gains the slightest suspicion we shall certainly fail. Secondly, I must have a good man to assist me. Aubert did extremely well in the case of Marguerite Zell, the dancing woman who came from The Hague; I will have him. I shall leave Paris this evening. Tell Madame Gabrielle to come home and wait till I return, and to hold herself in readiness with Aubert." Hecq nodded his assent, but did not ask me a single question. That was what I liked most about him; he never asked one how he intended to proceed. His trust, when it was given, was complete; he expected results, and did not bother about mere details. Yet, when his assistance was asked at a difficult point, he was always completely at the service of his employees. He knew I had no particular affection for the Surete, because in one important case they had bungled, and brought me to disaster which nearly cost me my life. So he merely shook hands and wished me good luck. Twenty-four hours later I arrived at the Hotel de la Poste, in Issoire, a dull, remote little town in Auvergne, and next morning set about making inquiries regarding Jules Cauvin. First of all, I looked up the entry of his birth at the Prefecture, which showed that he was the son of the village postman of Champeix, seven miles from Issoire. I found out also that his father had been imprisoned for seven years for thefts of letters. It was necessary to make many inquiries without arousing suspicion, therefore I was compelled to spend several days at my task. I made some interesting discoveries, for naturally the entire neighbourhood was familiar with Cauvin's rise to wealth, and he had been put under that microscopic observation and discussion which is so marked a feature of provincial life everywhere, but especially in France.
