Mary Slessor was no ordinary woman, indeed she was no ordinary missionary. Brought up in Dundee, one of eleven children, Mary was called to mission. Setting sail for West Africa on the 5th August 1876, Mary arrived one month later. Bruce McLennan examines this remarkable story of a woman who shared the Gospel, stood up against inequality and impacted all areas of life in Calabar with boldness and conviction. McLennan also considers the debt owed to the work of previous missionaries who had established the work and looks at the legacy of Slessor after her death.
