A Silence doesn’t announce that it’s based on a true story, but its origins are not hard to find. In this film by Belgian director, Joachim Lafosse, the crime that looms in the background is that of paedophile, rapist and serial killer Marc Dutroux, who kidnapped, imprisoned and tortured a series of young girls from 1985 to 1996. What’s most astonishing is that Dutroux was jailed for five cases of abduction and rape in 1989, then released after only three years in prison. When he regained his freedom, six more victims followed, four of them murdered.
