Allan Quatermain by H. Rider Haggard - is an 1887 novel by H. Rider Haggard. It is the sequel to Haggard's 1885 novel King Solomon's Mines.At the beginning of the book, Allan Quatermain's only son has died and he longs to get back into the wilderness. He persuades Sir Henry Curtis, Captain John Good, and the Zulu chief Umslopogaas to accompany him, and they set out from the coast of east Africa into the territory of the Maasai. While staying with a Scottish missionary, Mr. Mackenzie, they run into a group of Maasai who kidnap Mr. Mackenzie's daughter. The Maasai demand the life of one of the party as ransom, but instead they lead an attack on the Maasai, catching them by surprise and slaughtering them.The group then travel by canoe along an underground river to a lake (which turns out to be the sacred lake of Zu-Vendis) in the kingdom of Zu-Vendis beyond a range of mountains. The Zu-Vendi are a warlike race of white-skinned people isolated from other African races; their capital is called Milosis. At the time of the British party's arrival, they are ruled jointly by two sisters, Nyleptha and Sorais. The priests of the Zu-Vendi religion are hostile to the explorers as they had killed hippopotamuses - animals sacred to the Zu-Vendis - on their arrival, but the queens protect them.
