"Ah, I have thought a great deal about this affair," said he, adding that before he resigned his post as Judge of Instruction he had carefully reperused the notes of the case. He had again questioned the concierge of the Imperial Hotel and other persons. Since he had become Counsellor to the Court, he had indicated to his successor what he believed to be a clue; a robbery committed by a carefully made up Englishman had led him to believe the thief to be identical with the pretended Rochdale. Then there was nothing more. These steps had, however, been of use inasmuch as they barred the rule of limitation, and he laid stress on that fact. I consulted him then as to how much time still remained for me to seek out the truth on my own account. The last Act of Instruction dated from 1873, so that I had until 1883 to discover the criminal and deliver him up to public justice. What madness! Ten years had already elapsed since the crime, and I, all alone, insignificant, not possessed of the vast resources at the disposal of the police, I presumed to imagine that I should triumph, where so skilful a ferret as he had failed! Folly! Yes; it was so. Nevertheless, I tried. I began a thorough and searching investigation of all the dead man's papers. With that unbounded tenderness of hers for my stepfather, which made me so miserable, my mother had placed all these papers in M. Termonde's keeping. Alas! Why should she have understood those niceties of feeling on my part, which rendered the fusion of her present with her past so repugnant to me, any more clearly on this point than on any other? M. Termonde had at least scrupulously respected the whole of those papers, from plans of association and prospectuses to private letters. Among the latter were several from M. Termonde himself, which bore testimony to the friendship that had formerly subsisted between my mother's first husband and her second. Had I not known this always? Why should I suffer from the knowledge? And still there was nothing, no indication whatever to put me on the track of a suspicion. I evoked the image of my father as he lived, just as I had seen him for the last time; I heard him replying to M. Termonde's question in the dining-room of the Rue Tronchet, and speaking of the man who awaited him to kill him: "A singular man whom I shall not be sorry to observe more closely." And then he had gone out and was walking towards his death while I was playing in the little salon, and my mother was talking to the friend who was one day to be her master and mine. What a happy home-picture, while in that hotel room---- Ah! was I never to find the key of the terrible enigma? Where was I to go? What was I to do? At what door was I to knock?
