At this moment of despair and danger, his first thought was for Murphy. "If he be not on his guard, those monsters will murder him!" cried he. "It will be I who shall have caused his death,--my good, my faithful Murphy!" This cruel thought nerved the arm of Rodolph with fresh vigour, and again he bent his most powerful energy to endeavour to force the ponderous door. Alas! the thickly plated iron with which it was covered mocked his utmost efforts; and sore, weary, and exhausted, he was compelled to relinquish the fruitless task. Again he descended into the cave, in hopes of obtaining something which might serve as a lever to force the hinges or wrench the fastenings. Groping against the slimy walls, he felt himself continually treading on some sort of round elastic bodies, which appeared to slip from under his feet, and to scramble for safety past him. They were rats, driven by the fast-rising water from their retreats. Groping about the place on all fours, with the water half way up his leg, Rodolph felt in all directions for the weapon he so much desired to find; nothing but the damp walls met his touch, however, and, in utter despair, he resumed his position at the top of the steps,--of the thirteen stairs which composed the flight, three were already under water. Thirteen had ever been Rodolph's unlucky number. There are moments when the strongest minds are under the influence of superstitious ideas, and, at this juncture, Rodolph viewed the fatal amount of stairs as an ill augury. Again the possible fate of Murphy recurred to him, and, as if inspired by a fresh hope, he eagerly felt around the door to discover some slight chink, or opening, by which his cries for help might be heard. In vain; the dampness of the soil had swollen the wood, and joined it hermetically to the wet, slimy earth. Rodolph next tried the powers of his voice, and shouted with the fullest expansion of his lungs, trusting that his cries for assistance might reach the adjoining cabaret; and then, tired and exhausted, sat down to listen. Nothing was to be heard, no sound disturbed the deep silence which reigned, but the drop, drop, drop, the dull, trickling, monotonous bubbling of the fast-increasing waters. His last hope extinguished, Rodolph seated himself in gloomy despair, and, leaning his back against the door, bewailed the perilous situation of his faithful friend,--perhaps at that very moment struggling beneath the assassin's knife. Bitterly did he then regret his rash and venturesome projects, however good and generous the motives by which he had been instigated; and severely did he reproach himself for having taken advantage of the devotion of Murphy, who, rich, honoured, and esteemed by all who knew him, had quitted a beloved wife and child, to assist Rodolph in the bold undertaking he had imposed on himself.
