It has not come as soon as I expected. Two days have passed, and though Mademoiselle Letellier grows paler and thinner, nothing more has been said about the stairs. But the time has not passed without its incident, and a serious enough one, too, if these women are, as I fear, in the secret of the hidden chamber.
It is this: In the garden is a white stone. It is plain-finished but unlettered. It marks the resting-place of Honora Urquhart. For reasons which we all thought good, we have taken no uninterested person into the secret of this grave, any more than we have into that of the hidden chamber.
Consequently no one in the house but myself could answer Madame Letellier, when, stopping in her short walk up and down the garden path, she asked what the white stone meant and what it marked. I would not answer her. I had seen from the window where I stood the quick surprise with which she had come to a standstill at the sight of this stone, and I had caught the tremble in her usually steady voice as she made the inquiry I have mentioned above. I therefore hastened down and joined her before she had left the spot.
"You are wondering what this stone means," I observed, with an indifferent tone calculated to set her at her ease. Then suddenly, and with a changed voice and a secret look into her face, I added: "It is a headstone; a dead body lies here."
She quivered, and her lids fell. For all her self-possession—and she is the most self-possessed person I ever saw in my life—she showed a change that gave me new thoughts and made me summon up all the strength I am mistress of, in order to preserve the composure which her agitation had so deeply shaken.
"You shock me," were her first words, uttered very slowly, and with a transparent show of indifference. "It is not usual to find a garden used for a burial place. May I ask whose body lies here? That of some faithful black or of a favorite horse?"
"It is not that of a horse," I returned, calmly. And greatly pleased to find that I had placed her in a position where she would be obliged to press the question if she would learn anything more, I walked slowly on, convinced that she would follow me.
She did, giving me short side glances, which I bore with an equanimity that much belied the tempest of doubt, repugnance and horror that were struggling blindly in my breast. But she did not renew the subject of the grave. Instead of that, she opened one of her most fascinating conversations, endeavoring by her wiles and graces to get at my confidence and insure my good will.
And I was hypocrite enough to deceive her into thinking she had done so. Though I showed her no great warmth, I carefully restrained myself from betraying my real feelings, allowing her to talk on, and giving her now and then an encouraging word or an inviting smile.
