Not a lot of nudity and little blood, this giallo is closer to Agatha Christie than Edward Wallace. That said, it does have Paul Naschy in it and it’s directed by Javier Aguirre, who made Count Dracula’s Great Love.
Patty Shepherd (Edge of the Axe) stars as Lisa, who has gathered twelve of her husband’s closest friends and informs them that she believes that one of them is the killer. That said, there are really seventeen suspects when you add in the butler, chauffeur, maid and gardener.
All the phone lines get cut, people start getting killed off and secrets are revealed. There aren’t many Spanish giallo that I can think of, other than Clockwork Terror, The House That Screamed, Blue Eyes of the Broken Doll, The Corruption of Chris Miller and A Dragonfly for Each Corpse. Come to think of it, I know way more of these movies than I thought I did.
You can get this on the new Vinegar Syndrome Forgotten Gialli box set.
