Vampire Haunting by Biagio Fasano (B. Magic)

The title of this eBook suggests the vampire theme underlying this impromptu mentalism/bizarre magic effect. Simply by using six playing cards, it empowers the illusionist to be always ready to perform with eyes closed (while blindfolded, without any trickery whatsoever, or otherwise remaining turned to one side for the entire duration of the experiment), with no need whatsoever to see the cards.

A female spectator is chosen in the role of the first victim, the only one who survived the bite of the vampire and therefore able to sense its presence nearby. She will choose, without communicating it to the mentalist, whether to take refuge in the north or south sector of the city. Accordingly, she will change the point of view with which she will observe the fan of cards that, after each face up and down shuffle, will be shown to her, in order to convey or not the feeling of danger she will feel.

At the end of the fourth shuffle, the illusionist will be able to announce where the woman had taken refuge and, more importantly, will be able to "blindly" capture the vampire's card to show the audience its face!
