He tore open the departmental envelope as he spoke and drew forth a bit of folded paper. It was not the official letter-head, but at a glance Philip recognized the inspector's scrawling writing and his signature. It was one of MacGregor's quiet boasts that the man did not live who could forge his name. An astonished whistle broke from his lips as he read these few lines:

Follow your conscience, whatever you do. Both God and man will reward you in the end.

Felix MacGregor.

And this was all. There was no date, no word of explanation; even his own name had been omitted from this second order. He picked up the envelope which had fallen to the floor and looked at the postmark. It had been stamped four-thirty. It was after five, an hour later, that he had received his verbal instructions from MacGregor! The inspector must have written the note before their interview of the preceding afternoon—before his repeated injunction of “Whatever happens, bring back your prisoner!” But this letter was evidently intended as final instructions since it had been sent so as to reach him at this time. What did it mean? The question buzzed in Philip's brain, repeated itself twenty times, fifty times, as he hurried through the gathering darkness of the semi-polar night toward the log hotel of the place. He was convinced that there was some hidden motive in the inspector's actions. What was he to understand?

Suddenly he stopped, a hundred yards from the glimmering lights of the Little Saskatchewan hotel, and chuckled audibly as he stuffed his pipe. It flashed upon him now why MacGregor had chosen him instead of an ordinary service man to bring down the prisoner from Wekusko. MacGregor knew that he, Philip Steele, college man and man of the world, would reason out the key to this little puzzle, whereas Sergeant Moody and others of his type would turn back for explanations. And Inspector MacGregor, twenty years in the service, and recognized as the shrewdest man-hunter between the coasts, wished to give no explanation. Philip's blood tingled with fresh excitement as the tremendous risk which the inspector himself was running, dawned upon him. Publicity of the note which he held in his hand would mean the disgrace and retirement even of Felix MacGregor.

He thrust the letter in his pocket and hurried on. The lights of the settlement were already agleam. From the edge of the frozen river there came the sound of a wheezy accordion in a Chinese cafe, and the howling of a dog, either struck by man or worsted in a fight. Where the more numerous lights of the one street shone red against the black background of forest, a drunken half-breed was chanting in half-Cree, half-French, the chorus of the caribou song. He heard the distant snapping of a whip, the yelping response of huskies, and a moment later a sledge and six dogs passed him so close that he was compelled to leap from their path. This was Le Pas—the wilderness! Beyond it, just over the frozen river which lay white and silent before him, stretched that endless desolation of romance and mystery which he had grown to love, a world of deep snows, of silent-tongued men, of hardship and battle for life where the law of nature was the survival of the fittest, and that of man, “Do unto others as ye would that they should do unto you.” Never did Philip Steele's heart throb with the wild, free pulse of life and joy as in such moments as these, when his fortune, his clubs, and his friends were a thousand miles away, and he stood on the edge of the big northern Unknown.

As he had slept through the trainmen's dinner hour, he was as hungry as a wolf, and he lost no time in seating himself in a warm corner of the low, log-ceilinged dining-room of the Little Saskatchewan. Although a quarter of an hour early, he had hardly placed himself at his table when another person entered the room. Casually he glanced up from the two letters which he had spread out before him. The one who had followed him was a woman. She had turned sharply upon seeing him and seated herself at the next table, her back so toward him that he caught only her half profile.

It was enough to assure him that she was young and pretty. On her head she wore a turban of silver lynx fur, and about this she had drawn her glossy brown hair, which shone like burnished copper in the lamp-glow, and had gathered it in a bewitchingly coquettish knot low on her neck, where it shone with a new richness and a new warmth with every turn of her head. But not once did she turn so that Philip could see more than the tantalizing pink of her cheek and the prettiness of her chin, which at times was partly concealed in a collarette of the same silver gray lynx fur.

He ate his supper almost mechanically, in spite of his hunger, for his mind was deep in the mysterious problem which confronted him. Half a dozen times he broke in upon his thoughts to glance at the girl at the opposite table. Once he was sure that she had been looking at him and that she had turned just in time to keep her face from him. Philip admired pretty women, and of all beauty in woman he loved beautiful hair, so that more and more frequently his eyes traveled to the shining wealth of copper-colored tresses near him. He had almost finished his supper when a movement at the other table drew his eyes up squarely, and his heart gave a sudden jump. The girl had risen. She was facing him, and as for an instant their eyes met she hesitated, as if she were on the point of speaking. In that moment he recognized her.

It was the girl in the photograph, older, more beautiful—the same soft, sweet contour of face, the same dark eyes that had looked at him in MacGregor's office, filled with an indescribable sadness now, instead of the laughing joy of girlhood. In another moment he would have responded to her hesitation, to the pathetic tremble of her lips, but before words could form themselves she had turned and was gone. And yet at the door, even as she disappeared, he saw her face turned to him again, pleadingly, entreatingly, as if she knew his mission and sent to him a silent prayer for mercy.
