Inspiration...

I also found this radio story based on the theme of jealousy taken from "The Whistler" called "Jealousy" . I haven't actually listened to the full story however, the description links very closely to the ideas we have for our thriller opening.

The image is too small to see, however, the description is :
       "A sick woman is sure that her husband is trying to kill her so he can be with another woman. She therefore decides to make the first move."

When I saw this it made me think of our narrative and how this radio story foreshadows what happens in our thriller opening with the murder/killing that had just taken place.
