When Jules Beaubien's father died, the young man found himself heir to the stout old mansion in Montreal and the big fortune the family had made in the lumber of the great Canadian forests. But on his deathbed his father made a confession: 20 years ago he met a squaw of the Ojibway tribe and a girl child was born to them; she was now up in Nipissing country with a French-Canadian family who adopted her by arrangement with the father. Old Beaubien's last words to his son exacted a promise that the boy would find his half-sister, educate and care for her, and give her a liberal share of the estate. As soon as affairs were settled Jules started on his quest to find Annette. Arriving in the Nipissing country, he found that the family had moved from the valley, but he was informed that a woodsman, Baptiste Le Grande, could tell him all about her as he had been her sweetheart. He loved the girl with all the strength of his rough manhood, but a city man came along and betrayed her. Baptiste tried to tell the story, but his rage would not permit him to be coherent and Father Paul continued. He told Jules that the seducer had abandoned the girl and gone back to America. Annette, knowing she was disgraced, ran away from her foster parents and wandered to the camps where the women of the trappers tried to care for her. She became delirious, but she never mentioned the man's name. When her child was born she wandered out into the storm with her babe in her arms, lay down in the snow, and died, and the wolves ate her and the child. The rage of Jules and Baptiste was terrible. They swore to find the man and kill him. Baptiste took a crucifix from his bosom, both men kissed the symbol, and for two years the quest of vengeance continued. In the Indian summer Jules heard that frequently parties of engineers would quarter at Andrew McTavish's house in the forest. Here Jules and Baptiste resolved to put up for a while. Two other men arrived, civil engineer Mr. McDonald and his assistant Mr. Huntley, who were surveying for a Canadian railroad. McDonald was a splendid specimen of physical manhood, about 40 years old and very entertaining. His ability at his profession made him rich and with all he was a man of courage and likable. McTavish's daughter Hilda, a fascinating girl, did the cooking and housekeeping, and it was not surprising that McDonald and Jules soon noticed that each were contesting for the smiles of the Scotsman's daughter. Hilda was not adverse to the pleasantries of the good-looking boarders, for her life was far from happy; her mother, not being able to stand the irascible McTavish, had run away when Hilda was a child, and the father vented his revenge and hatred upon the daughter. Soon the rivalry between Jules and MacDonald became an open book. Jules loved Hilda, while the other man was simply playing for a dishonorable advantage. One day the men admitted their rivalry face to face. Jules was willing to play the game fair. The rogue laughed in the other man's face, admitted that he had a wife in America, but boasted of his power over women. In his bravado he told of an affair some years ago with a little girl up in the Nipissing country. It was the story of Annette. Jules would have killed him on the spot, but he was a man of honor; he could not assassinate, he must fight this fiend. Then he must tell also Baptiste, who would also want to kill him, and commit this deed he would if Jules fell in the fight. McDonald, feeling he was losing ground with Hilda, planned to work her ruin through the father. He told McTavish that he had a good mother in America that would care for and educate Hilda and that then he would marry her. The old Scotsman was only too willing to get rid of the girl and demanded of her that he would go with McDonald. Jules had told Hilda of the good love and the bad love and she learned to love Jules. When McTavish ordered her to go with McDonald she resisted. The old man in his rage would have seized her by the throat and strangled her, but Jules bore him to the floor of the cabin, while Baptiste from outside the window covered MacDonald with his Winchester. The fight was desperate and long, but Jules seized Hilda and, with Baptiste and Huntley, who discovered his master's villainy, the four hastened to the creek and in a canoe which had been furnished with supplies for the trip, made towards the Canadian railway for Montreal. McDonald followed and Jules left the party at a landing to meet him. A desperate duel was fought, in which McDonald was killed, and after burying the body, Jules and his party hastened to home and happiness.
