And it has always seemed to me that the presence of John Silence, so potent, so quietly efficacious, produced an effect, if one may say so, of a psychic forcing-house, and hastened incalculably the bringing together of these two “wild” lovers.  In that sudden awakening had occurred the very psychological climax required to reveal the passionate emotion accumulated below.  The deeper knowledge had leaped across and transferred itself to her ordinary consciousness, and in that shock the collision of the personalities had shaken them to the depths and shown her the truth beyond all possibility of doubt.

“He’s sleeping quietly now,” the doctor said, interrupting my reflections.  “If you will watch alone for a bit I’ll go to Maloney’s tent and help him to arrange his thoughts.”  He smiled in anticipation of that “arrangement.”  “He’ll never quite understand how a wound on the Double can transfer itself to the physical body, but at least I can persuade him that the less he talks and ‘explains’ to-morrow, the sooner the forces will run their natural course now to peace and quietness.”

He went away softly, and with the removal of his presence Sangree, sleeping heavily, turned over and groaned with the pain of his broken head.

And it was in the still hour just before the dawn, when all the islands were hushed, the wind and sea still dreaming, and the stars visible through clearing mists, that a figure crept silently over the ridge and reached the door of the tent where I dozed beside the sufferer, before I was aware of its presence.  The flap was cautiously lifted a few inches and in looked—­Joan.

That same instant Sangree woke and sat up on his bed of branches.  He recognised her before I could say a word, and uttered a low cry.  It was pain and joy mingled, and this time all human.  And the girl too was no longer walking in her sleep, but fully aware of what she was doing.  I was only just able to prevent him springing from his blankets.

“Joan, Joan!” he cried, and in a flash she answered him, “I’m here—­I’m with you always now,” and had pushed past me into the tent and flung herself upon his breast.

“I knew you would come to me in the end,” I heard him whisper.

“It was all too big for me to understand at first,” she murmured, “and for a long time I was frightened—­”

“But not now!” he cried louder; “you don’t feel afraid now of—­of anything that’s in me—­”

“I fear nothing,” she cried, “nothing, nothing!”

I led her outside again.  She looked steadily into my face with eyes shining and her whole being transformed.  In some intuitive way, surviving probably from the somnambulism, she knew or guessed as much as I knew.

“You must talk to-morrow with John Silence,” I said gently, leading her towards her own tent.  “He understands everything.”

I left her at the door, and as I went back softly to take up my place of sentry again with the Canadian, I saw the first streaks of dawn lighting up the far rim of the sea behind the distant islands.
