Once more the prisoned thing that had been Gerald Rathbone gazed round the cell, striving with terrible intensity of thought to understand it and penetrate its mysteries. Here he had been put and here he had remained ever since that sickening moment when he had been talking to Sir William Gouldesbrough. He had been standing in front of the baronet, when his arms had been gripped from behind and unseen fingers held a damp cloth, with a faint sickly and aromatic smell, over his face. A noise like the rushing of great waters sounded in his ears, there was a sense of falling into a gulf of enveloping blackness.
He had awakened in the place which he was now surveying again, with frightful and fascinated curiosity.
In the brilliant light of the electric bulbs every object in the cell was clearly seen. The place was not small. It was oblong in shape, some sixteen feet by twelve. The walls were built of heavy slabs of Portland stone cemented together with extreme nicety and care. The door of the cell was obviously new. It was a heavy steel door with a complicated system of locks—very much like the door of a safe. The whole place, indeed, suggested that it had been used as a strong-room at some time or other. There was no window of any kind in the cell. In the centre of the arched roof there was a barred ventilator, and close by an electric fan whirled and whispered unceasingly. The sound made by the purring thing as it revolved two thousand times a minute was almost the only sound Gerald Rathbone heard now.
The floor of the cell was covered with cork carpet of an ordinary pattern. The victim cast his glance on all this without interest. Then, as if he did so unwillingly, but by the force of an attraction he could not resist, he stared, with lively doubt and horror rippling over his face, at something which stood against the opposite wall. He saw a long narrow couch of some black wood, slanting upwards towards the head. The couch stood upon four thick pedestals of red rubber, which in their turn rested upon four squares of thick porcelain. The whole thing had the appearance of a shallow box upon trestles, and at the head was a curious pillow of india-rubber. At the side of this thick pad was a collar-shaped circlet of vulcanite clamped between two arms of aluminium, which moved in any direction upon ball-pivots.
He stared at this mysterious couch, trying to understand it, to realize it.
He rose from the narrow bed on which he sat, and advanced to the centre of the cell—to the centre, but no further than that.
Around his waist a circlet of light steel was welded, and from it thin steel chains ran through light handcuffs upon his wrists, and were joined to steel bands which were locked upon his ankles. And all these chains, hardly thicker than stout watch-chains, but terribly strong, were caught up to a pulley that hung far above his head and, in its turn, gave its central chain to another pulley and swivel fixed in the roof.
In the half of his cell where his little bed was fixed, the prisoner had fair liberty of movement, despite his shackles. He could sit or lie, use his hands with some freedom. But whenever he attempted to cross the invisible line which divided one part of the cell from the other, the chains tightened and forbade him.
He stood now, straining to the limit of his bonds, gazing at the long couch of black wood, with its rubber feet, its clamps and collar at the head.
Above the mysterious couch, upon a triangular shelf by the door, was something that gleamed and shone brightly. It was a cap of metal, shaped like a huge acorn cup, or a bishop's mitre. From an ivory stud in the centre of the peak, coils of silk-covered wire ran to a china plug in the wall.
