He sprang back to the door, and sternly demanded to be instantly released.

There was no reply—there was not even a movement in the other apartment, and he was suddenly oppressed with the fear that he was in the power of an organized gang of robbers who might be meditating putting him out of the way, and no one would ever be the wiser regarding his fate.

He felt that he had been very heedless, for he did not even know the name of the street he was on. His fascinating companion had so concentrated his attention upon herself that he had paid no heed to locality.

He repeated his demand to be released, beating loudly upon the door to enforce it.

But no notice was taken of him, and a feeling almost of despair began to settle over him.

He glanced about the room he was in, to see if there was any other way of escape, when, to his dismay, he found that the apartment was padded from floor to ceiling, and thus no sound within it could be heard outside.

It was lighted only from above, where strong bars over the glass plainly indicated to him that the place was intended as a prison, although there were ventilators at the top and bottom, which served to keep the air pure.

The place was comfortably, even elegantly, furnished with a bed, a lounge, a table and several chairs. There were a number of fine pictures on the walls, handsome ornaments on the mantel, besides books, papers and magazines on the table.

But Ray could not stop to give more than a passing glance to all this. He was terribly wrought up at finding himself in such a strait, and paced the room from end to end, like a veritable maniac, while he tried to think of some way to escape.

But he began to realize, after a time, that giving way to such excitement would do no good—that it would be far wiser to sit quietly down and try to exercise his wits; but his mind was a perfect chaos, his head ached, his temples throbbed, his nerves tingled in every portion of his body, and to think calmly in such a state was beyond his power.
