Days and weeks and months of a loneliness which Billy had never known before followed after his pilgrimage to Deane's grave. It was more than loneliness. He had known loneliness, the heartbreak and the longing of it, in the black and silent chaos of the arctic night; he had almost gone mad of it, and he had seen Pelliter nearly die for a glimpse of the sun and the sound of a voice. But this was different. It was something that ate deeper at his soul each day and each night that he lived. He had believed that thought of Isobel and his memories of her would make him happier, even though he never saw her again. But in this he was mistaken. The wilderness does not lend to forgetfulness, and each day her voice seemed nearer and more real to him, and she became more and more insistently a part of his thoughts. Never an hour of the day passed that he did not ask himself where she was. He hoped that she and the baby Isobel had returned to the old home in Montreal, where they would surely find friends and be cared for. And yet the dread was upon him that she had remained in the wilderness, that her love for Deane would keep her there, and that she would find a woman's work at some post between the Height of Land and the Barrens. At times there possessed him an overwhelming desire to return to McTabb's cabin and find where they had gone. But he fought against this desire as a man fights against death. He knew that once he surrendered himself to the temptation to be near her again he would lose much that he had won in his struggle during the days of plague in Couchée's cabin. So his feet carried him steadily westward, while the invisible hands tugged at him from behind. He did not go straight to Fond du Lac, but spent nearly three weeks with a trapper whom he ran across on the Pipestone River. It was June when he struck Fond du Lac, and he remained there a month. He had more than half expected to pass the winter there, but the factor at the post proved a disagreeable acquaintance, and he did not like the country. So early in July he set out deeper into the Athabasca country to the west, followed the northern shore of the big lake, and two months later came to Fort Chippewyan, near the mouth of the Slave River.
