Horace Holly and his ward Leo Vincey head off to darkest Africa to to find a Kingdom ruled by a white Queen known as "She" short for "She Who Must Be Obeyed" ( so it wasn't John Mortimer).
This is a tale of the supernatural and a 'ripping yarn" that Haggard is known for, it has never been out of print but I dear say its days are numbered as it is seen as 'Imperialist'.
It s a fun adventure read and hopefully the cancellers never get to it.
