"Just a thought!" she answered easily, though her face flushed.

Stane did not ask her what the thought was. He was conscious of something enigmatic in her attitude, and her evident reserve for a second time prevented him from pursuing the matter further. He waited a moment, then he uttered the thought which had been in his own mind.

"When the storm is over and there is a crust on the snow we will go exploring together. We may find the camp from which this woman comes. If the air keeps still through the night, it will be quite easy to follow her trail in the snow."

Helen looked at him with eyes half-veiled under her long lashes. Did he suspect who the intruder was?

"You are very anxious to find this woman of mystery?" she asked.

"Not particularly so," he laughed in reply, "but I shall be very glad to find out who our neighbours are, and to learn whether we can secure any help from them."

The girl was reassured by the unconcerned answer. It seemed clear now that Miskodeed had not even occurred to his mind, and the reserve in her manner disappeared.

"You think we shall be dependent on their help?" she asked. "You are afraid that we shall not weather through by ourselves?"

Stane laughed again. "Oh no! I have no fears on that score; but it will depend on their possession of dogs whether we have to camp here all winter or not; for we could not possibly make Fort Malsun without them, particularly as I do not know the overland trail. Not that the knowledge is really essential now, since judging from the fact that Ainley went down the lake it seems likely that there is a way to Malsun river in that direction. But we simply must have dogs."

"Then in the morning we follow the mysterious one's trail?"
