***1/2. There are two kinds of gialli: the urban gialli drawing a large part of their inspiration from iconic cities (Venice, London, Milan, Chattanooga) and gialli taking place in confined places (churches, mansions, schools, olive groves). Here, in this giallo inspired by Agatha Christie's 'And Then, There Were None', the whole action takes place in a castle. And the film is a MUST for any giallo fan. A discovery.
