“If you had asked me this a few days ago,” she answered, after a pause, “I could only have given you a negative answer. But I have overheard Mr Yelverton’s confession to you, and now that I am strong again, I am determined that neither he nor you shall longer remain in doubt regarding the mystery surrounding Aline Cloud.”

“What is it?” I cried excitedly. “Tell us quickly.”

“No,” she answered, with a wave of the hand. “In this affair we must exercise patience, or those who are guilty will assuredly escape us. Besides, we have to ensure our own safety also.”

“Our own safety!” Jack echoed. “What do you mean?”

“Have I not narrowly escaped death?” she asked. “If we are not wary, another attempt, perhaps more successful, may be made.”

“You anticipate assassination because those who are guilty are aware that you are now in possession of their secret?” I cried. “Then let us act in union with care and discretion. What has caused you to preserve your silence until now?”

“Circumstances which rendered my secrecy imperative,” she answered. “Until now I only entertained suspicions; but these have been confirmed, therefore to me the truth is apparent. In order, however, for us to solve the mystery, it is necessary that you should both obey me implicitly, without asking any questions, for to some of your demands I should be compelled to give false answers. Trust in me, both of you, and I will reveal to you something stranger than you have ever dreamed.”

“We do trust you,” we both answered with one accord.

“I’m ready to act in any manner you direct,” I added.

“And you will not fear, even though a plot may be laid against your life?” she inquired with concern.
