Following the disappearance of his brother, Sir Henry Curtis tracks down Allan Quartermain, a trader and hunter who knows Africa as well as any white man. Curtis's brother has taken an expedition into the uncharted interior of Africa in search of the fabled diamond mines of King Solomon, but has not returned. Quartermain possesses an ancient map drawn in blood purporting to show the way to the mines and agrees to mount a rescue in return for a share of the bounty. The expedition journeys over perilous mountains, through scorching deserts and tribal war, but upon reaching the mines Quartermain must face his toughest challenge: the evil and clever Gagaoola. Haggard's Quatermain adventures have been used as the template for the Hollywood movies about Indiana Jones.
