Marius, however, was heart-broken, for everything had disappeared again through a trap-door. He saw nothing ahead of him, and his life was once more plunged into the mystery in which he had been groping. He had seen again momentarily and very closely the girl whom he loved, the old man who appeared her father,--the strange beings who were his only interest and sole hope in this world,--and at the moment when he fancied that he should grasp them, a breath had carried off all these shadows. Not a spark of certainty and truth had flashed even from that most terrific collision, and no conjecture was possible. He no longer knew the name of which he had felt so certain, and it certainly was not Ursule, and the Lark was a nickname; and then, what must he think of the old man? Did he really hide himself from the police? The white-haired workman whom Marius had met in the vicinity of the Invalides reverted to his mind, and it now became probable that this workman and M. Leblanc were one and the same. He disguised himself then, and this man had his heroic side and his equivocal side. Why did he not call for help? why did he fly? was he, yes or no, the father of the girl? and, lastly, was he really the man whom Thénardier fancied he recognized? Thénardier might have been mistaken. These were all so many insoluble problems. All this, it is true, in no way lessened the angelic charm of the maiden of the Luxembourg. Poignant distress,--Marius had a passion in his heart, and night over his eyes. He was impelled, he was attracted, and he could not stir; all had vanished, except love, and he had lost the sudden instincts and illuminations of even that love. Usually, this flame which burns us enlightens us a little, and casts some useful light without, but Marius no longer even heard the dumb counsel of passion. He never said to himself, Suppose I were to go there, or try this thing or the other? She whom he could no longer call Ursule was evidently somewhere, but nothing advised Marius in what direction he should seek her. All his life was now summed up in two words,--absolute uncertainty, in an impenetrable fog,--and though he still longed to see her, he no longer hoped it. As a climax, want returned, and he felt its icy breath close to him and behind him. In all these torments, and for a long time, he had discontinued his work, and nothing is more dangerous than discontinued work; for it is a habit which a man loses,--a habit easy to give up, but difficult to re-acquire.
