“I speak the truth in order to save from your merciless clutches one woman whose fair name has never been besmirched. I speak for Liane’s sake.”

Zertho turned from him with a fierce imprecation on his lips, declaring that the whole story was a tissue of falsehoods, and denouncing his companion Brooker as the actual assassin.

“You forget,” said Richards, “that in addition to myself there was a second witness, Nelly Bridson, the girl with whom your victim had carried on a mild and harmless flirtation prior to meeting Mariette. You forget that she was with me, and actually saw you commit the deed.”

This truth rendered him voiceless.

“May I, in future, enjoy an absolutely clear conscience that I had no hand in the actual crime?” the Captain asked earnestly, turning to Richards.

“Certainly,” he answered, quickly. “Both Nelly and myself saw every movement clearly, for the moon was shining bright as day. We heard you shout in horror and dismay to the assassin; we saw the blow struck; we saw the theft committed, and watched you pick up the knife, which you threw down again instantly at the moment when I rushed forward.”

“I was, alas, only half-conscious of my actions,” he answered. “But the enormity of the crime must have sobered me instantly, for I remember a man approaching—who it was I was not aware until this moment—and knowing that we had been discovered and were in peril, flew for my life back to the Promenade, reaching home by a circuitous route about midnight.”

“You need have no further fear of this man,” Richards assured him. “His plan was ingenious, to shift the crime from his own shoulders to yours, and at the same time to marry Liane, but fortunately his own actions convict him. Liane has shown bravery and self-denial, which should further endear her to the heart of the man who loves her, and if the truth I have told brings back her happiness and peace of mind I shall not have spoken in vain.”

“I have much to thank you for,” Liane faltered, her face bright with a new-born happiness. “You have indeed revived within me hope, life and love. I knew this man was crafty and cruel, but I never dreamed that he himself had committed the crime with which he charged my father. I saw that he was inexorable and relentless, and was compelled to wrench myself from George, whom I loved, and promise to become the wife of—of this assassin.”

“Assassin!” cried Zertho. “No, the prospect of becoming Princess d’Auzac proved too attractive for you! It was because both you and your father wanted money and position, that you were ready to become my wife.”
