King Solomon's Mines #1

A party of explorers travels to Africa following the route of King Solomon in search of a legendary diamond treasure hidden in a secret chamber. Along the way, they encounter Twala, a native king whose people nearly destroy them, but they manage to defeat the witch Gagool and her dark magic through a supernatural sign from the sun. After overcoming jungle perils and discovering a white man, George, stranded in the desert for two years, the expedition successfully completes its mission and returns to England with tales of adventure.
