West paced the narrow space, his brain whirling, as he attempted to reason the affair out, his own helplessness becoming more and more apparent.  What could he do?  There was but one answer—­absolutely nothing as he was then situated.  He could only wait for some movement on the part of the others; his fate was out of his own hands; he had been a fool, and must pay the price.  The cords about his wrists chafed and hurt with each movement.  The metal wash-stand gave him an inspiration; its upper strip was thin, and somewhat jagged along the edge; possibly it might be utilized to sever the strands.  It was better to try the experiment than remain thus helplessly bound.  With hands free he could at least defend himself.

He made the effort, doubtfully at first, but hope came as the sharp edge began to tear at the rope.  It was slow work, awkward, requiring all the strength of his arms, yet he felt sure of progress.  He could feel the strands yield little by little, and redoubled his efforts.  It hurt, the rope lacerating his wrists, and occasionally the jagged steel cut into the flesh cruelly, but the thought of freedom outweighed the pain, and he persevered manfully.  At last, exercising all his muscle, the last frayed strand snapped.  His wrists were bleeding, and the hands numb, but the severed cord lay on the floor and he again had the free use of his arms.  The sudden freedom brought new hope and courage.  He listened at the door, testing the knob cautiously.  There was no yielding, and for the moment no sound reached him from without.  The woman was doubtless there on guard, and any effort he might make to break down the door would only bring the whole gang upon him.  Unarmed, he could not hope to fight them all.  As he stood there, hesitating, unable to determine what to attempt, he became aware of a throbbing under foot, increasing in intensity.  West knew instantly what it meant—­they were testing out the engine; if all worked well, the boat would cast off.

He sprang back to the port and stared out, eagerly hoping that, as they swept out into the lake, he might find some opportunity to communicate with some one on the pier.  Perhaps by this time Mac would have arrived, and be watching their departure, unable to intervene, as he had no warrant for arrest, or any definite knowledge that the yacht was being used for a criminal purpose.  He had not long to wait.  Hurrying steps echoed along the deck; a voice shouted out some order, and the end of a loosened rope dropped splashing into the water astern; the boat trembled to the pulsations of the engine, and West realized that it was at first slowly, then more swiftly, slipping away into the broad water.  Already he could perceive the white wake astern, and, an instant later, as the turn to the right widened, he had a glimpse of the pier, already separated from him by a broad expanse of trembling water.  Above the noise his voice would scarcely reach that distance.  A crowd of
