Sanders of the River. By Edgar Wallace. A Novel of Africa. Sanders of the River is a novel by Edgar Wallace. It is set in British Nigeria. Sanders is a British colonial District Commissioner in Colonial Nigeria. He tries to rule his province fairly, including the various tribes comprising the Peoples of the River. He is regarded with respect by some and with fear by others, among whom he is referred to as "Sandi" and "Lord Sandi". He has an ally in Bosambo, a literate and educated chief. When Sanders goes on leave, another chief, King Mofolaba, spreads the rumour that "Sandi is dead." Intertribal war seems inevitable, and the situation is made worse by gun-runners and slavers. His relief, Lord Ferguson, is unequal to the task. Sanders returns to restore peace. When Bosambo's wife Lilongo is kidnapped, the chief tracks down her kidnappers. Captured by them, he is saved by a relief force commanded by Sanders. Bosambo kills King Mofolaba in retaliation for his wife's kidnapping.
