He was released after five years, and twenty years later he was rehabilitated. The Vercnocke family would hardly talk about that black past, not even after his death in 1989. In 2015, Bout Vercnocke considers the time finally ripe to dig up the dark past of his father: how and to what extent his father collaborated, how big was his involvement and responsibility?
