Verges went on to become a high-flying lawyer, making headlines around the world thanks to a client list that includes some of the most infamous names of modern times: Nazi war criminal Klaus Barbie, Venezuelan revolutionary Carlos the Jackal, former Iraqi deputy prime minister Tariq Aziz and ex-Yugoslav leader Slobodan Milosevic.
Verges' life story reads like a novel, but there is one chapter that he prefers to leave unopened: from 1970 until 1978, when he left his wife and children and disappeared.
He has referred to this period as "the dark side" of his life, leading to much speculation about these missing years.
