He lost himself in conjectures; he could not doubt as to his own identity, but how was it that he, who had fallen in the Rue de la Chanvrerie, had been picked up by the police agent on the bank of the Seine, near the bridge of the Invalides? Some one had brought him from the market district to the Champs Élysées, and how,--by the sewer? Extraordinary devotion! Some one? Who? It was the man whom Marius was seeking. Of this man, who was his saviour, he could find nothing, not a trace, not the slightest sign. Marius, though compelled on this side to exercise a great reserve, pushed on his inquiries as far as the Préfecture of Police, but there the information which he obtained led to no better result than elsewhere. The Préfecture knew less about the matter than the driver of the hackney coach; they had no knowledge of any arrest having taken place at the outlet of the great drain on June 6; they had received no report from the agent about this fact which, at the Préfecture, was regarded as a fable. The invention of this fable was attributed to the driver; for a driver anxious for drink-money is capable of anything, even imagination. The fact, however, was certain, and Marius could not doubt it, unless he doubted his own identity, as we have just said. Everything in this strange enigma was inexplicable; this man, this mysterious man, whom the driver had seen come out of the grating of the great drain, bearing the fainting Marius on his back, and whom the police agent caught in the act of saving an insurgent,--what had become of him? What had become of the agent himself? Why had this agent kept silence? Had the man succeeded in escaping? Had be corrupted the agent? Why did this man give no sign of life to Marius, who owed everything to him? The disinterestedness was no less prodigious than the devotion. Why did this man not reappear? Perhaps he was above reward, but no man is above gratitude. Was he dead? Who was the man? What was he like? No one was able to say: the driver replied, "The night was very dark." Basque and Nicolette in their start had only looked at their young master, who was all bloody. The porter, whose candle had lit up Marius's tragic arrival, had alone remarked the man in question, and this was the description he gave of him: "The man was frightful." In the hope of deriving some advantage from them for his researches, Marius kept his blood-stained clothes which he wore when he was brought to his grandfather's. On examining the coat it was noticed that the skirt was strangely torn, and a piece was missing. One evening Marius was speaking in the presence of Cosette and Jean Valjean about all this singular adventure, the countless inquiries he had made, and the inutility of his efforts; Monsieur Fauchelevent's cold face offended him, and he exclaimed with a vivacity which had almost the vibration of anger,--
