"Wouldn't Mabel double-up with you?" I said instead, "or give you an adjoining room, so that you could leave the door between you open? There's space enough, heaven knows."

And then, as the gong sounded in the hall below for dinner, she said, as with an effort, this thing:

"Mabel did ask me—on the third night—after I had told her. But I declined."

"You'd rather be alone than with her?" I asked, with a certain relief.

Her reply was so gravely given, a child would have known there was more behind it: "Not that; but that she did not really want it."

I had a moment's intuition and acted on it impulsively. "She feels it too, perhaps, but wishes to face it by herself—and get over it?"

My sister bowed her head, and the gesture made me realize of a sudden how grave and solemn our talk had grown, as though some portentous thing were under discussion. It had come of itself—indefinite as a gradual change of temperature. Yet neither of us knew its nature, for apparently neither of us could state it plainly. Nothing happened, even in our words.

"That was my impression," she said, "—that if she yields to it she encourages it. And a habit forms so easily. Just think," she added with a faint smile that was the first sign of lightness she had yet betrayed, "what a nuisance it would be—everywhere—if everybody was afraid of being alone—like that."

I snatched readily at the chance. We laughed a little, though it was a quiet kind of laughter that seemed wrong. I took her arm and led her towards the door.

"Disastrous, in fact," I agreed.
