I have spoken to Vicky who made this series and personally congratulated her. I have listened to all 6 episodes, and can highly recommend it. ALthough I had read The Psychic Mafia some years back, this show has so much more in it, interviews and stories etc.
I have encouraged her to try to pitch another series but on Helen Duncan as there is a lot to cover there, but I think there is already a film being made about her, so not sure if the BBC will want to do something else.
Also if you want to know about some psychic tricks, there is a lot in the podcasts covering how Lemar did his tricks.
A bad ass who will beat you like he's using the fists of god.
