Hello guys,
I hope is the right section. I've done a search on the café but can't fine it..



Some years ago I saw a version of the lie detector plot were the performer uses just 5 or 6 (?) blank cards.

The performer asked the spectator if the cards were, for example, a king and count the cards by spelling the word. Then he turns the card and on the blank card there was written "lie"
Then he ask for example if it was red and, after counting 'r-e-d', on the blank card there was written "truth".

At the end he reveales a blank card with the spectators card written on it.

Could please someone be so kind as to tell me the name of this effect and were I can find It?

Thank you

Whilst not identical, the closest version I can think of is Cameron Francis's Nothing But The Truth

Thank you so much!!

It's exactly the one I meant!!

As I saw it a long time ago I couldn't remember it clearly
