She and Allan

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. "She and Allan" is a novel by H. Rider Haggard, first published in 1921. It brought together his two most popular characters, Ayesha from She (to which it serves as a prequel), and Allan Quatermain from King Solomon's Mines. Wanting to learn if he can communicate with deceased loved ones, adventurer and trader Allan Quatermain seeks a meeting with the feared Zulu witch-doctor Zikali, who tells Allan to seek out a great white sorceress who rules a hidden kingdom far to the north, and he charges Allan to take a message to her. He also gives Allan a necklace with a strange amulet, carved in Zikali's own likeness. Zikali claims it has great magical powers that will protect Allan on his journey, but he must on no account take it off. (Excerpt from Wikipedia)
