Not with any vaulting hopes, for an egress from this inner space seemed less unlikely than from the one he occupied, he pulled himself on the top of the intervening wall and lowered himself over the other side. At the full stretch of his arms he failed to touch anything with his feet; an alarming thought came to him; he would have pulled himself back, but the top of the wall was crumbling to his fingers, a mass of rotten mortar threatening each moment to break below his grasp, and he realised with a spasm of the diaphragm that now there was no retreat. What—this was his thought—what if this was the mouth of a well? Or a mediaeval trap for fools? He had seen such things in French castles. In the pitch darkness he could not guess whether he hung above an abyss or had the ground within an inch of his straining toes.

To die in a pit!

To die in a pit! good God!—was this the appropriate conclusion to a life with so much of open-air adventure, sunshine, gaiety, and charm in it? The sweat streamed upon his face as he strove vainly to hang by one of his arms and search the cope of the crumbling wall for a surer hold with the other; he stretched his toes till his muscles cramped, his eyes in the darkness filled with a red cloud, his breath choked him, a vision of his body thrashing through space overcame him, and his slipping fingers would be loose from the mortar in another minute!

To one last struggle for a decent mastery his natural manhood rose, and cleared his brain and made him loose his grip.

He fell less than a yard!

For a moment he stopped to laugh at his foolish terror, and then set busily to explore this new place in which he found himself. The air was fresher; the walls on either hand contracted into the space of a lobby; he felt his way along for twenty paces before he could be convinced that he was in a sort of tunnel. But figure a so-convenient tunnel in connection with a prison cell! It was too good to be true.

With no great surrender to hope even yet, he boldly plunged into the darkness, reason assuring him that the cul-de-sac would come sooner or later. But for once reason was wrong; the passage opened ever before him, more airy than ever, always dank and odorous, but with never a barrier—a passage the builders of the castle had executed for an age of sudden sieges and alarms, but now archaic and useless, and finally forgotten altogether.

He had walked, he knew not how long, when he was brought up by a curious sound—a prolonged, continuous, hollow roar as of wind in a wood or a sea that rolled on a distant beach. Vainly he sought to identify it, but finally shook aside his wonder and pushed on again till he came to the apparent end of the passage, where a wooden door barred his progress farther. He stopped as much in amazement as in dubiety about the door, for the noise that had baffled him farther back in the tunnel was now close at hand, and he might have been in a ship's hold and the ship all blown about by tempest, to judge from the inexplicable thunder that shook the darkness. A score of surmises came quickly, only to be dismissed as quickly as they came; that extraordinary tumult was beyond his understanding, and so he applied himself to his release. Still his lucky fortune remained with him; the door was merely on a latch. He plucked it open eagerly, keen to solve the puzzle of the noise, emerging on a night now glittering with stars, and clamant with the roar of tumbling waters.

A simple explanation!—he had come out beside the river. The passage came to its conclusion under the dumb arch of a bridge whose concaves echoed back in infinite exaggeration every sound of the river as it gulped in rocky pools below.

The landscape round about him in the starshine had a most bewitching influence. Steep banks rose from the riverside and lost themselves in a haze of frost, through which, more eminent, stood the boles and giant members of vast gaunt trees, their upper branches fretting the starry sky. No snow was on the spot where he emerged, for the wind, blowing huge wreaths against the buttresses of the bridge a little higher on the bank, had left some vacant spaces, but the rest of the world was blanched well-nigh to the complexion of linen. Where he was to turn to first puzzled Count Victor. He was free in a whimsical fashion, indeed, for he was scarcely more than half-clad, and he wore a pair of dancing-shoes, ludicrously inappropriate for walking in such weather through the country. He was free, but he could not be very far yet from his cell; the discovery of his escape might be made known at any moment; and even now while he lingered here he might have followers in the tunnel.
