So this was the last chapter! By Jove! how hot and close the room was! It was annoying to feel so dull and listless, but there was some excuse: nine o’clock at night is not a time when a man is at his freshest, and there was nothing so wearing as this closely woven intellectual work, where every thread had to be followed to its end, every detail thought out, every possible ramification explored, and the mind kept at its highest tension throughout, straining to cover the whole ground and to order in logical sequence its myriad elusive thoughts. Difficult? Why, there was nothing to compare to it! But what was the good of magnifying troubles? Here was the final chapter, the conclusion which was to be so masterly, already mapped out in his mind, only waiting to be transferred to paper. Armstrong wiped his damp forehead, and seized the pen. The room was lit as he liked it, with only a lamp casting a subdued light on his desk; the rest in deepest gloom. Now was the time to begin. But he was terribly tired.

*********

Kr-rk!

Armstrong leaned back in his chair, and pressed his hand to his head. Something inside seemed to have broken with a snap, or a tiny shutter had fallen away, as in a camera, revealing a hidden lens in his brain. His head was clearer and freer, as if some clogging veil had suddenly been removed, and before his eyes there burned a new light, steady and cold, but brilliant. A cooler, purer air filled the room. The present melted away from his vision. * * * * *

Far away—so far that everything was dwarfed, but yet as distinct in every detail as though it had been close at hand—Armstrong saw a vision.

A dark underground dungeon, with damp standing in beads on its bare stone walls; a man, bound, gagged, and helpless; another, black-masked and sullen of movement; a third, seated on a small platform, with his face in shadow. A feeble hanging lamp, swaying to and fro in the draughts of the cell, was the only illumination.

The vision came nearer and nearer, and grew larger as it came, until it reached Armstrong and filled his room, and he felt the dank breath of the dungeon stir his hair. He looked again: the masked man was at his elbow, the man on the dais was above him—unrecognisable in the shadow, but smiling gently; that much he could see. Then he looked at the third man, the prisoner; and a thrill of dread went through him, for he recognised himself,—in old-world, long-forgotten garb, but still himself. And then the whole grew real, with a deadly reality; he was no more a mere spectator, but a part of the vision, and the vision was a part of his own existence. The chill of the room fell on his spirit, filling him with vague, horrible forebodings: the present mingled with the past, and his spirit passed into the limp, helpless figure on the rack. He—he himself, and none other—was the victim in the torture chamber, and the world was black around him.

There was a clank of steel on the floor, as though little instruments had been dropped, and then a sudden sharp pang struck him from an unseen source. Another, another, and yet another,—a very multitude of keen stabbing pangs. In uncontrollable agony he raised his voice to shout with pain, but the gag stopped him, choked him, throttled his curses. And the dark figure smiled from above.

Then came hot, burning, throbbing pains that shot through him, turning the blood in his veins to fire, and gnawing his vitals till they consumed away. He tried to turn, to roll, to ease himself in any way; but he was bound and rigid and helpless, and his efforts only increased the torture. And still the figure sat motionless above him. He turned his streaming eyes upwards in mute appeal, and his answer was a smile.

Then the sharp pains and the burning misery ceased for a while, and his aching limbs rested, and all seemed over. But the presiding fiend waved a silent signal, and worse came—stretching, straining torture, that nearly pulled the wretched frame asunder (well if it had!), and dull grinding agonies, worse than the sharper pains, more cruel and relentless than the stabs or blows or thrusts.
