Vertudieu!” swore the Marquise, “and what is this betrothal, what this faithfulness? She has not seen her betrothed for three years. She was a child at the time of their fiancailles. Think you her faithfulness to him is the constancy of a woman to her lover? Go your ways, you foolish boy. It is but the constancy to a word, to the wishes of her father. Think you constancy that has no other base than that would stand between her and any man who—as you might do, had you the address—could make her love him?”

“I do say so,” answered Marius firmly.

She smiled the pitying smile of one equipped with superior knowledge when confronted with an obstinate, uninformed mind.

“There is a droll arrogance about you, Marius,” she told him, quietly. “You, a fledgling, would teach me, a woman, the ways of a woman’s heart! It is a thing you may live to regret.”

“As how?” he asked.

“Once already has mademoiselle contrived to corrupt one of our men, and send him to Paris with a letter. Out of that has sprung our present trouble. Another time she may do better. When she shall have bribed another to assist her to escape; when she, herself, shall have made off to the shelter of the Queen-mother, perhaps you will regret that my counsel should have fallen upon barren ground.”

“It is to prevent any such attempt that we have placed her under guard,” said he. “You are forgetting that.”

“Forgetting it? Not I. But what assurance have you that she will not bribe her guard?”

Marius laughed, rose, and pushed back his chair.

“Madame,” said he, “you are back at your contemplation of the worst side of this affair; you are persisting in considering only how we may be thwarted. But set your mind at rest. Gilles is her sentinel. Every night he sleeps in her anteroom. He is Fortunio’s most trusted man. She will not corrupt him.”
