Thank you for the opportunity to help you with your question!
When the woman is struggling, there is a lot of fast pace editing as she tries to fight off her killer,
We never see any of the woman's wounds close up. Most likely it is because in the 1960s they did not have the sufficient equipment to do that.
Nevertheless, the editing quickly moves from the killer to the victim, showing her reaction as she gets stabbed and then quickly back to the murderer.
When the murderer leaves, the editing is slowed down as the woman falls to the floor and supposedly to her death.
In about a minute, the film shows about 70 fast paced cuts without showing the killers face even once. This holds the attention of the audience and keeps them watching.Please let me know if you need any clarification. I'm always happy to answer your questions.
