From the blurb:

"The whereabouts of King Solomon's legendary diamond mines had been inscribed in blood on an ancient map now in the possession on Allan Quatermain. His enthralling story begins on a ship steaming up the east coast of Africa. On board he meets Sir Henry Curtis and Captain John Good, and agrees to join their search for Curtis's younger brother, missing, believed dead, in the interior. Aided by the treasure map, the men set out on a perilous journey, an adventure tense with dnager and excitement that culminates in a mountain trek to the vast caves of Solomon - and what they find there."
