This fact set me thinking. What could she be doing in Buda Pesth? Why was she coiling the net of intrigue round the young Count—the future Duke? Was she still a secret Government agent promoted to an international position? Who was behind her in it all? These and other questions of the kind were started.

Then came the mysterious theft of the ducal jewels; and through my instinct, or intuition, call it by what term you may, that which was a mystery to so many became my key to the whole problem. Count Karl was in the toils of the lovely French-woman; he was one of the very few persons who had access to the jewels; he was admittedly a man of dissipated habits; and it was an easy deduction that she had instigated the robbery; more to test the extent of her power over him, perhaps, than because she coveted the jewels. There was much more than mere vulgar theft in it; that was but one of the coils she threw round him. She was in the Hungarian capital because others had sent her to find out secrets; and she was drawing the net about his feet to ruin him for other and greater purposes.

Here then was my course ready shaped for me. I had entered the Minister's household to win his confidence as a possible means to the end I had in view; but the study of my father's papers had shown me that the General might have had a hand in the grim drama, and in such an event I might find my way blocked.

But if I took the field against Madame d'Artelle and cut the meshes of the net of ruin being woven round Count Karl, I should have on my side the future Duke, the man with the power in his hands, and himself quite innocent of all connexion with my father's fate. Success might easily lie that way.

I acted promptly. I went to Madame d'Artelle's; and the interview was one which would have greatly interested his Excellency. I posed as the student and governess with my own way to make in the world; and the Frenchwoman, eager to buy my silence and wishing to separate me from the Minister, urged me to trust to her to advance my interests, and to live with her in the meantime.

I consented, of course; and it was then I spoke out to General von Erlanger. Thus with one stroke I established close relations with two sides in the intrigue.

It was with a feeling of some inward satisfaction at the progress I was making that I went to stay in Madame d'Artelle's house; and, as I had not yet seen the man whom I planned to deliver from her hands, I looked forward with much curiosity and interest to meeting him. I should need to study him very closely; for I was fully alive to the infinite difficulties of what I had undertaken to do.

But those difficulties were to prove a hundred-fold greater than I had even anticipated; and my embarrassment and perplexity were at first so great, that I was all but tempted to abandon the whole scheme.

I was sitting with Madame d'Artelle one afternoon reading—I kept up the pretence of studying—when Count Karl was announced. I rose at once to leave the room.

"Don't go," she said. "I wish to present you to the Count."
