Then came a very special instruction.

"I have come provided, too, with a key, the use of which I must explain."

It was a double key—a long, slender stem, with a key at each end—one about the size which opens an ordinary room door; the other, as small, almost, as the key of a dressing-case.

"You cannot employ too much caution to-morrow night. An interruption would murder all my hopes. I have learned that you occupy the haunted room in the Dragon Volant. It is the very room I would have wished you in. I will tell you why—there is a story of a man who, having shut himself up in that room one night, disappeared before morning. The truth is, he wanted, I believe, to escape from creditors; and the host of the Dragon Volant, at that time, being a rogue, aided him in absconding. My husband investigated the matter, and discovered how his escape was made. It was by means of this key. Here is a memorandum and a plan describing how they are to be applied. I have taken them from the Count's escritoire. And now, once more I must leave to your ingenuity how to mystify the people at the Dragon Volant. Be sure you try the keys first, to see that the locks turn freely. I will have my jewels ready. You, whatever we divide, had better bring your money, because it may be many months before you can revisit Paris, or disclose our place of residence to any one; and our passports—arrange all that; in what names, and whither, you please. And now, dear Richard" (she leaned her arm fondly on my shoulder, and looked with ineffable passion in my eyes, with her other hand clasped in mine), "my very life is in your hands; I have staked all on your fidelity."

As she spoke the last word, she, on a sudden, grew deadly pale, and gasped, "Good God! who is here?"

At the same moment she receded through the door in the marble screen, close to which she stood, and behind which was a small roofless chamber, as small as the shrine, the window of which was darkened by a clustering mass of ivy so dense that hardly a gleam of light came through the leaves.

I stood upon the threshold which she had just crossed, looking in the direction in which she had thrown that one terrified glance. No wonder she was frightened. Quite close upon us, not twenty yards away, and approaching at a quick step, very distinctly lighted by the moon, Colonel Gaillarde and his companion were coming. The shadow of the cornice and a piece of wall were upon me. Unconscious of this, I was expecting the moment when, with one of his frantic yells, he should spring forward to assail me.

I made a step backward, drew one of my pistols from my pocket, and cocked it. It was obvious he had not seen me.

I stood, with my finger on the trigger, determined to shoot him dead if he should attempt to enter the place where the Countess was. It would, no doubt, have been a murder; but, in my mind, I had no question or qualm about it. When once we engage in secret and guilty practices we are nearer other and greater crimes than we at all suspect.

"There's the statue," said the Colonel, in his brief discordant tones. "That's the figure."
