DIscarded - Canadian Historical Mysteries, #4

When the British arrived in Winnipeg in the 1800s it was convenient for the men to take Metis wives. They were called a la vacon du pays - according to the custom of the country. These women bore the brunt of ensuring survival in the harsh environment. Without them the British army and fur traders would not have survived the brutal winters. However, as society evolved it became accepted that wives must be white, schooled in British ways, fashionable in the European sense and married by the Anglican church.
The Metis wives and their 'country born' offspring were thrown out and forced to fend for themselves. The unrepentant husbands continued to live comfortably with their 'new' wives. It was inevitable that some discarded wives did not accept their fate quietly and hard feelings on both sides were unavoidable. When the bodies of two discarded Metis wives, Marguerite and Marie-Anne, are found floating in the Red River, Guilliame Mousseau, sets out to get to the bottom of his sister Margueite's murder.
