Tenebre is an Argento film about a killer who is murdering women using a fiction novel as a guideline. Naturally, the book’sauthor is the main suspect or at least expected to be able to shed some light on the murders. This isn’t s much a horror film as it is suspense, although there are some very stylish death scenes. Not my favorite, but John Saxon is great and I am looking forward to exploring his filmography further.
