Sir Henry Rider Haggard was an English writer of adventure novels set in exotic locations, predominantly Africa, and the creator of the Lost World literary genre. His stories, situated at the lighter end of the scale of Victorian literature, continue to be popular and influential. He was also involved in agricultural reform and improvement in the British Empire. "Finished" is a 1917 novel by H. Rider Haggard featuring Allan Quatermain. It is the last in a trilogy about the Zulu kingdom, which also includes Marie and Child of Storm, and involved the dwarf Zikali. It is set against the background of the Anglo-Zulu War of 1879, covering events leading up to the war, and ending with the death of Cetewayo. Quatermain is depicted as being one of the few survivors of the Battle of Isandhlwana. Like others in the series, several real-life characters appear, such as Cetewayo and Anthony Durnford.(Excerpt from Wikipedia)
