Not a vintage giallo by any means but a very decent late effort from Sergio Martino who brought us such gems as, The Strange Vice of Mrs Wardh and All the Colours of the Dark. Has something of the feel of TV movie perhaps in the seeming lack of budget and more particularly in this rather bloodless and sexless tale. Gripping tale it nevertheless is, however, and there are so many conservatoire students and teachers to keep us guessing whilst a very large number fall victim to the mysterious killer who leaves a mark upon the stomach. Enzo De Caro is excellent in the lead investigator role. I didn't recognise him but it seems he is a fairly big name in Italian film and TV. A minor giallo but still worth a watch and particularly interesting to note the facets of the genre that remain acceptable (disturbed childhood causing violent trauma and pedophile teachers) and those that don't (sex and gore). I also missed that late 60s interior decoration and the bottle of J&B!
