I think the stories are mostly true. Allen had that sort of reputation. Remember that was the time of the "Happy Valley Set". Lots of debauchery, swapping of partners, etc etc among certain members of the upper society.

Bunny Allen also had an affair with Ava Gardner during the filming of "Mogambo" while Clarke Gable had an affair with Gardner, and then switched to Grace Kelly. Paralleling a lot with the plot of the movie in fact. Allen was a PH paid to help with the movie.

It really gets a bit much in his book the "what goes on safari, stays on safari" crap. I agree with you there. I too am amazed no one put a bullet in the jerk.

But in the end an interesting life. For him at least.

I think he wrote another book as well, where the content is more interesting.
