Hi, a couple of years I knew a trick involving some old photographs of people, a necklace and something more I can’t remember. Maybe an envelope or two. One of the pictures was the murderer and one was the victim. The necklace was supposed to belong the victim. It was really engaging and had a good backstory, but I can’t remember what it was called. I think it was a DIY project, just instructions on how to make the props (photos) and how to perform it. Please let me know if you know what it’s called .

Vanishing and appearing necklace?

Or maybe grandma´s necklace?
There are many variations on the market, for example:

Thanks for all suggestions, but I finally found it in my Gmail - it's Choked by Simon Scott.
