"I do more, I reward you; you are a faithful bearer of notes, a gentle messenger of love. But you forget your master is waiting for you."

"Ah! that is true," said the young man, springing towards the door.

But scarcely had he advanced three steps before the floor gave way beneath his feet. He stumbled, extended both hands, gave a fearful cry, and disappeared in the dungeon of the Louvre, the spring of which Catharine had just touched.

"So," murmured the queen, "thanks to the fellow's obstinacy I shall have to descend a hundred and fifty steps."

The queen mother returned to her apartments, lighted a dark lantern, came back to the corridor, closed the spring, and opened the door of a spiral staircase which seemed to lead to the bowels of the earth. Urged on by the insatiable thirst of a curiosity which was but the minister of her hatred, she reached an iron door which turned on its hinges and admitted her to the depths of the dungeon. Bleeding, crushed, and mutilated by a fall of a hundred feet or more, but still breathing, lay poor Orthon.

Beyond the thick wall the waters of the Seine were heard roaring, brought to the foot of the stairs by a subterranean channel.

Catharine entered the damp and unwholesome place, which during her reign had witnessed many a fall similar to the one it had just seen, searched the body, seized the letter, made sure that it was the one she desired, then pushing aside the body with her foot she pressed a spring, the bottom of the dungeon sank, and the corpse, carried down by its own weight, disappeared in the direction of the river.

Closing the door again, Catharine ascended, shut herself in her closet, and read the note, which contained these words:

"This evening at ten o'clock, Rue de l'Arbre Sec, Hôtel de la Belle Étoile. If you come send no reply; otherwise send back NO by the bearer.

"De Mouy De Saint Phale."
