The Comtesse de Serizy, the Marquis de Ronquerolles’ sister, gave a great ball at the beginning of the following week, and Mme de Langeais was sure to go to it. Armand was the first person whom the Duchess saw when she came into the room, and this time Armand was looking out for her, or so she thought at least. The two exchanged a look, and suddenly the woman felt a cold perspiration break from every pore. She had thought all along that Montriveau was capable of taking reprisals in some unheard-of way proportioned to their condition, and now the revenge had been discovered, it was ready, heated, and boiling. Lightnings flashed from the foiled lover’s eyes, his face was radiant with exultant vengeance. And the Duchess? Her eyes were haggard in spite of her resolution to be cool and insolent. She went to take her place beside the Comtesse de Serizy, who could not help exclaiming, “Dear Antoinette! what is the matter with you? You are enough to frighten one.”

“I shall be all right after a quadrille,” she answered, giving a hand to a young man who came up at that moment.

Mme de Langeais waltzed that evening with a sort of excitement and transport which redoubled Montriveau’s lowering looks. He stood in front of the line of spectators, who were amusing themselves by looking on. Every time that she came past him, his eyes darted down upon her eddying face; he might have been a tiger with the prey in his grasp. The waltz came to an end, Mme de Langeais went back to her place beside the Countess, and Montriveau never took his eyes off her, talking all the while with a stranger.

“One of the things that struck me most on the journey,” he was saying (and the Duchess listened with all her ears), “was the remark which the man makes at Westminster when you are shown the axe with which a man in a mask cut off Charles the First’s head, so they tell you. The King made it first of all to some inquisitive person, and they repeat it still in memory of him.”

“What does the man say?” asked Mme de Serizy.

“‘Do not touch the axe!’” replied Montriveau, and there was menace in the sound of his voice.

“Really, my Lord Marquis,” said Mme de Langeais, “you tell this old story that everybody knows if they have been to London, and look at my neck in such a melodramatic way that you seem to me to have an axe in your hand.”

The Duchess was in a cold sweat, but nevertheless she laughed as she spoke the last words.

“But circumstances give the story a quite new application,” returned he.

“How so; pray tell me, for pity’s sake?”
