Kevin Pietersen: Beast Of Man BBC Radio 5 Live

Saving rhinos is fraught with contradictions. To save them from extinction, will we have to be cruel to be kind? Something KP also knows about in his closest friendships. In this final episode KP opens up about his relationships - and the dark solution that may yet save the rhino from extinction. Do we even have time?

The war to save the rhino has brought a father and daughter to the very edges of love and hate. Kevin meets the father figure of the rangers in this part of South Africa - Don English - a man who has had to kill to save the lives of the rhinos. But the effect on his daughter has been immense. Will he ever stop?

After meeting the trophy hunter, KP is convinced the law needs to be changed to stop it. He takes his fight to the UK Government - for an encounter with Environment Secretary Michael Gove amid the chaos of Brexit. But that's not the only place his influence reaches. Over champagne and canapes, Kevin tells the brutal truth to the rich - and hears it from a dragon.

Trophy hunters have become the villains of the media. Their photos cause outrage, and sorrow for their prey. Kevin Pietersen thinks they're 'scumbags'. But what will happen when he meets one?

Vietnam is the reason for the current surge of rhino killing. It's where their horns are prized, for traditional medicine and status. It's taken at elite parties: and Kevin hears exactly how from an inside source.

When the mission is critical - there has to be trust. In the war to save the rhino however, trust has gone. The rangers have been infiltrated.
