From its extraordinary opening sequence set in a catacomb of mummies, Rosi’s neglected thriller never loosens its grip. While America had Watergate, Italy’s own (bloodier) decade of political turmoil inspired this story of the serial assassination of judges. With Ventura’s paranoid detective suspecting the entire political spectrum and beyond, Rosi’s blurring of the boundaries between criminality and terrorism chimes with today’s crises – and remains deeply chilling.
