This is an autobiographical account of a pair of missionaries (Bill and Mollie Tett) who take the gospel to un-reached parts of Africa in the 1920s-1960s.
They were part of the SUM (Sudan United Mission). This was set up in 1904 with the aim of planting a chain of gospel churches across the African continent, running from Nigeria to Cameroon to Chad to Sudan. Bill and Mollie started their work in Sudan and moved Westwards, taking the gospel to the unreached mountainous tribes of central Africa. They finished in Jos, Nigeria.
