Then Nikola approached the door and threw it open.

"Come in, Hatteras," he said. "Your presence is discovered."

"For heaven's sake, Nikola, tell me what this means," I cried, seeing that the girl did not turn towards me. "Is she asleep, or have you brought your diabolical influence upon her?"

"She is not asleep, and yet she is not conscious of her actions," he answered. "There is something in this that passes our philosophy. Had I any idea that she contemplated such a thing, I would have used every effort to prevent it. Miss Trevor, believe me, you must go home with Sir Richard," he continued, tenderly raising the girl to her feet as he spoke.

"I cannot go until you have sworn to forgive," was her reply.

"I must have time to think," he answered. "In the morning you will know everything. Trust me until then, and remember always that while Nikola lives he will be grateful."

Then he assisted me to conduct her down-stairs, and across the two courtyards, to the little postern door through which we had entered the palace.

"Have no fear for her," he said, addressing me. "She will go home as she came. And in the morning she will remember nothing of what has transpired."

Then taking her hand in his he raised it to his lips, and a moment later had bade me farewell, and had vanished into the palace once more.

As I tracked her from the hotel, so I followed her back to it again. I was none the less anxious, however. If only Nikola would abandon his purpose, and release his enemy, her action and my anxiety would not be in vain. But would he do so, and in the event of his doing this, would his prophecy that Miss Trevor would, in the morning, remember nothing of what had transpired, prove true?
