A lurid and trashy, but always entertaining giallo from Riccardo Freda. Set In Ireland it sees haunted and unorthodox cop Luigi Pistilli investigating a set murders that revolve around Swiss ambassador Anton Diffring. The film is populated by red herrings aplenty; weird characters and some grisly throat slashing murders. Pistilli is powerful in the lead role and gets great support from a typically icy and aloof Diffring, while the great Dagmar Lassander provides the requisite Italian glamour and beauty. Freda's direction is brisk, if a touch workmanlike while Silvano Ippoliti provides some nice photography (including some vertigo-inducing cliff top sequences) and the film is given added class by a masterly score from Stelvio Cipriani.
