“I understand it all now, darling. All is plain, and our estrangement has only rendered our love the more perfect.”

“You are generous to forgive, Gerald,” she answered in a low, faltering tone. “But I swear it was not my fault. In my ignorance of the world and its ways I took one false step long ago while still at school, and then could not draw back. I became a traitress and a spy!”

“And what of Yolande de Foville?” I inquired. “She was one of us, and in the service of France,” my love replied. “Like myself, she also was held in bondage. She wished to marry the young Count de Hochberg, an aide-de-camp of the Emperor William; but Bertini, who was in love with her, refused to allow her. It was because of jealousy that he made the ingenious attempt upon her life by the same means that he did later upon an Englishman in Paris, named Payne, who recognised him and suspected him of espionage. He is in possession of the knowledge of some subtle alkaloid poison, which he once boasted in my hearing to be even more deadly than the Indian Bikh poison, and unknown in the science of toxicology.”

“And where is Yolande now?”

“In Rome. Having obtained some secret of Bertini’s past, and a knowledge of his attempt upon her life, she defied him, and, freeing herself from the secret service, married de Hochberg only a fortnight ago. She is spending her honeymoon in southern Italy.”

“She is married!” I exclaimed, surprised.

“Yes. Her declarations of love for you were all false, made at the instigation of those schemers, Wolf and Bertini, who intended that she should worm from you certain diplomatic secrets. She hated her position, but, like myself, was powerless and compelled to submit.”

“To you alone, my love, is due the breaking-up of this ingenious band of spies, and the frustrating of the great conspiracy against England, which has, it seems, been fostered and aided by certain of the Powers.”

“And have you really perfect confidence in my honour and purity, Gerald?” she asked again, looking at me dubiously.

“I love you, darling,” I answered, bending down once more to kiss her beautiful mouth; “and that my confidence in you remains unshaken and is the same to-day as it was long ago in Scotland when I first declared my love, will be shown by our marriage, which nothing can now prevent. We are about to come into our kingdom.”
