I have the Japanese VHS to this as I'm a sucker for any Damiano Damiani crime movie. I haven't watched it in a while but I remember it to be very solid but not quite up there with IO hO Paura. It had a similar tempo and vie to Perche si Uccide un Magistrato & Un Uomo in Ginocchio with the usual strong performances from Gemma & Balsam.
