The night was clear, starlit but moonless, and the cliff as he reached it looked down upon him with majestic and sullen disdain. The ages had passed over and left it scarred and seared but still defiant and inaccessible. Renwick paused a moment to be sure of his ground and then boldly crawled up over the chaos of tumbled bowlders and broken masonry, until he reached the wall of solid rock, where he stopped again to regain his breath and examine the fissure that he had studied earlier in the day. It was a cleft in the rock, the result of some subterranean upheaval which had caused the whole crag to settle into its base; a fissure, originally a mere crack which had been widened and deepened by the erosion of time. Upon closer inspection, it was larger than it had appeared from below, perhaps ten feet in width at the outside, and tapering gradually as it rose.

He entered and ran his fingers along its sides, penetrating to its full depth until there was just room enough in which to wedge his bent body. Then rising cautiously, seated, so to speak, upon the incline which seemed to be about thirty degrees from the vertical, he dug the iron-shod toes of his peasant's boots into the roughnesses of the wall before him and rose, pushing with elbows and arms where the wall was too smooth for a foothold. It was hard work, and at the end of ten minutes, perspiring profusely, and leg and arm weary, he stopped upon a projecting ledge, where he found a perfect balance for his entire body, and relaxed. But he had gained fifty feet.

Above him was the long streak of pallid light shimmering against the gloom of the rock like the blade of a naked sword, with its point far above him among the stars. For a full five minutes he rested, and then went upward again, feeling with his finger ends while he braced his body, taking advantage of every foothold before and behind. At one spot the fissure widened dangerously, but he struggled inward; at another it went almost straight upward, requiring sheer strength of fingers; but at last he found another ledge and braced himself with his feet for another rest. He did not dare to look downward now, for fear of dizziness, but he knew that he had already come high. The sword blade was shorter, curved now more like a scimitar at its tip, which showed that the angle was greater.

But what if before he reached the rocky platform, the cleft should grow too narrow to admit the passage of his body? It was too late now to think of any such impediment. He struggled upward again, slipping back at times, clawing like a cat, with toes and fingers, fighting for his breath, but always mounting higher, his gaze upward toward a star in the heavens near the point of the scimitar. Would he ever reach the top? Bits of the rock crumbled, broke off and flew out into space, and once he slipped and slid outward, only saving himself from destruction by the aid of a jutting piece of jagged rock which caught in his clothing. A desperate venture—but successful, for with one final effort, with fingers torn, and knees and elbows bruised and bleeding, he hauled himself up to the level of the flat projection of rock upon which he dragged himself, exhausted and breathless, but so far, safe.

He lay there for a long time, flat on his back, his eyes dimmed with effort, his gaze on the stars, which now seemed to blink in a friendly way upon his venture. To succeed so far—failure was now impossible. Fearfully he peered over the edge of the cliff upon the velvety tree-tops of the valley below. Three hundred feet, four perhaps, and beyond to the left where the crag fell down to the very bed of the Dukla itself, black void—vacancy.

Above him still was the hazardous climb up the broken face of the rocks, but he did not fear it. His nerves were iron now. There were roots growing here, and small bushes, stunted trees, growing in the interstices of the rocks, and he climbed steadily, always looking upward, toward the breach in the wall now so very near, fifty feet, forty—and then the wall seemed to hang over him smooth and bare. So he hung there by a sturdy branch, one foot clinging, and studied the surface, descending a few feet carefully and then rising again to the left in a fissure, swinging himself along a narrow ledge where the masonry of the bastion joined the rock. Over this he climbed, finding solid footing at last, and then rest and a breathing space within the broken walls.

He lay behind a pile of rocks which had fallen from the walls of the watchtower, recovering his breath again, and the strength of his fingers, every bone of which was crying out in protest. He peered over into the depths below, trying to measure the distance he had come—three hundred feet—perhaps more. Could he find a rope of that length within the castle—? After a while he straightened in the shadow of the wall and peered cautiously up at the dark bulk of the keep and the tower, beyond the ruined chapel, searching its roofs and window for a sign of life. Silence. The ruin was deserted. For half an hour he watched and waited, and then sure that there was no chance that he had been observed, rose to his feet and moved forward stealthily into the shadows of the chapel. The roof had long since fallen in and been removed, but Renwick stumbled over a dusty tomb, toward the fragment of altar with the reredos still showing traces of sculpture, partially protected by a fragment of roof over the apse which had been spared by the wind and storm. To the right of the altar was a Gothic door, which had at one time led into the building adjoining, but upon investigation he found that it had been built in with solid blocks of stone. The other arch of the vaulted structure outside which he had noted from the mountain side was also filled by a wall. So far as Renwick could see, the ruined part of Schloss Szolnok was isolated, with no mode of egress from the habitable part.

Renwick had screened his movements as far as possible from view of the windows in the keep and other buildings, and now discovered that the lowest one was at least fifteen feet above the level of this rampart; and so before planning any action, he investigated the guardhouse, a fallen ruin upon the north bastion. He seemed to make out the forms of what had once been the stone treads of a circular stair in a tumbled mass. At first the appearance of the place discouraged him, for it seemed too far away from the main mass of buildings to furnish any communication with them, but as he peered among the fallen masonry he thought he detected a darker spot in the obscurity, and bending forward was aware of a heavy smell, as of mold and dampness. Upon investigation he discovered an irregular hole under the mass of stone, a little wider than his body.

He dared not strike a match for fear the glow of it might be observed from one of the windows of the keep, but testing the balance of the heavy stone steps, he decided to investigate, and so lowering his legs into the dark aperture he let himself hang from his waist and found that his toes encountered solidity. He tested his footing with his weight, and then let go, descending into the hole, which seemed to be a stairway, leading from the tower into the bowels of the rock. With a touch of fingers upon the efflorescent walls he moved cautiously down, step by step, sure now that this was the ancient corridor by which the men-at-arms passed from the guardhouse to the other rampart. Sixty-two steps down he counted, and then he reached a level, where he paused a moment to look at the vague blotch of gray which was the starlight. Even with eyes that had now grown accustomed to the darkness he could see nothing, and so deeming himself safe from observation, he struck a match, which struggled a moment against the foul air and then went out. But in the brief moment of partial illumination, Renwick made out a corridor extending straight before him, slightly downward. He followed it cautiously his hands stretched out, his toes feeling for pitfalls, and at last came to a rough wall.

Was this the end—a wall which shut off communication with the ruins? Emptiness to the right. He turned and followed the wall blindly, down its tortuous way, aware of a difficulty in breathing, and a throbbing at his temples down which the moisture was pouring profusely. In a while which seemed hours, the rough wall stopped, and his fingers encountered a wooden upright—a doorway—open. And testing the stone floor carefully he passed through it, the echoes of footfalls advising him that he was in a larger space. He peered in all directions, seeking a sign of light within, for it seemed that the air had now grown fresher, but he saw nothing, and so striking a third match which burned more brightly, he held it over his head for a moment and looked about him.
