“He made me promise.”

“Yes, and you kept the promise! My God, to think that you should be so mean!”

She leaned against the door-post, one hand at her throat, her eyes blazing even in the dim mingling of moonlight and of gloom. Robin was standing with his hands clasped about his head like a man frightened by the lightning in a storm.

“What can I do?—what can I do?—”

He repeated the words again and again, hardly knowing what he said. The very reiteration of the cry seemed to anger his sister, as the prattling of a child may anger a woman who is in trouble.

Tiphaïne stirred herself at last and stepped back over the threshold into her room.

“Go back to bed,” she said, quietly.
