This is an Italian Giallo from Dario Argento, beloved by his fans for his mastery of low-budget horror films. Plenty of fake red blood flows in this one along with some fun cinematography and a typically confusing plot. In one scene, a man yells at his creepy daughter saying "I told you not to do that again!" then slaps her. She smirks, then we see what she did - there is a green lizard with a pin stabbed through its body writhing on the ground in front of her father. Later he tells the protagonist "She's like that. Just loves to do horrible things. If you could just see what she does to lizards." Fortunately, even though the effect looks very real - I thought they really did stick a pin through a lizard - some of Argento's people explained that the lizard was not harmed, the effect was done with a false pin.
