Sir Charles Petrie has had close to 30 years' experience working in contexts of conflict and famine, some of it with Medecins Sans Frontieres and much of it with the UN system.His career with the UN brought him to witness the most ruthless atrocities and injustices humankind is capable of. He observed first-hand groups committing the three most egregious crimes; of genocide (in Rwanda and Sudan), war crimes (in the Democratic Republic of Congo, Myanmar, Somalia, Sri Lanka), and crimes against humanity (in Afghanistan, Democratic Republic of the Congo, Myanmar, Palestine, Somalia, Sri Lanka).Charles Petrie resigned from the United Nations as a result of his inability to get the organisation to investigate one of its own, who is alleged to have participated in the crime of genocide. The Triumph of Evil is the story of his search for justice.Charles Petrie was named Officer of the Order of the British Empire (OBE) in the 2014 New Year's Honours list for services to international peace, security and human rights. Upon his request, he received the award in Mogadishu. Following the death of his father in October 2021, he became the sixth Baronet of Carrowcarden.
