It was impossible not to be startled by the tone alone, though it was hardly above a whisper. Sweyn eyed his brother anxiously, but in the darkness could make nothing of his face. Then he laid his hands kindly and re-assuringly on Christian's shoulders and felt how he was quivering with excitement and horror.
"One sees strange things," he said, "when the cold has got into the brain behind the eyes; you came in cold and worn out."
"No," interrupted Christian. "I saw the track first on the brow of the slope, and followed it down right here to the door. This is no delusion."
Sweyn in his heart felt positive that it was. Christian was given to day-dreams and strange fancies, though never had he been possessed with so mad a notion before.
"Don't you believe me?" said Christian desperately. "You must. I swear it is sane truth. Are you blind? Why, even Tyr knows."
"You will be clearer headed to-morrow after a night's rest. Then come too, if you will, with White Fell, to the Hill Cairn; and if you have doubts still, watch and follow, and see what footprints she leaves."
Galled by Sweyn's evident contempt Christian turned abruptly to the door. Sweyn caught him back.
"What now, Christian? What are you going to do?"
"You do not believe me; my mother shall."
Sweyn's grasp tightened. "You shall not tell her," he said authoritatively.
