On a side issue, I should like to note that the film 'The Ghost and the Darkness' was completely inaccurate from a historical point of view, in as much as the 'hero' of the movie, was a complete invention of the scriptwriter. Still worth seeing though, as it is to read the original book "The Killers of Tsavo'.
