A sigh of relief escaped Juve. He had feared all his theories regarding the body at the Morgue the day before were going to collapse. "Go on, sir," he cried.

"Lady Beltham, on being shown into my private office, appeared to me much the same physically as I had known her previously, but she was no longer the great lady, cold, haughty, a trifle disdainful. She seemed crushed under a terrible load, a prey to awful mental torture. She made appeal to my discretion, both professionally and as a man of honour.

"She then spoke as follows: 'I am going to write a letter which, if it fell into the hands of a third person, would bring about a great calamity. This letter I shall intrust to you together with my Will which will instruct you what to do with it at my death. I will send you a visiting card with a line in my own handwriting every fortnight. If ever this card fails to come, conclude that I am dead, that they have murdered me, and carry that letter where I tell you—Avenge me!'"

"Well, what then?" cried Juve, anxiously.

"That is all, M. Juve. I have not seen Lady Beltham again, nor had any news of her. When I called at her residence I was told she was away. I have come to ask you whether you think she has been murdered."

Juve was pacing his room with great strides.

"Maître," he said at last, "your story confirms all I have suspected. Yes, Lady Beltham is dead. She has been murdered. That letter contained her confession and revealed not only her own crimes, but those of her accomplices, of her master—of—Fantômas. Fantômas killed her to free himself of a witness to his evil life."

"Fantômas! But Fantômas is dead."

"So they say."

"Have you proofs of his existence?"
