DVD:

Patrick Redford’s “Prevaricator” is more than a mentalism effect—it’s a concept that uses no gimmicks or props. Redford shares his diabolical method for detecting a lie, and discovering who is hiding a borrowed object and which hand they are hiding it in.

Two spectators are handed an object (say, a crumpled bill) and invited to play a game: one spectator will be the liar and one will tell the truth. While your head is turned, one of the two spectators takes the object. You, the mentalist, always know who the liar is, and which hand they are hiding the bill in. You can repeat the game indefinitely, and close by divining the serial number on the borrowed bill. 

Prevaricator is unlike any DVD you have seen. Because the system involved requires a spectator, you are given a performance practice session, so you can practice along with Patrick Redford, in the comfort of your own home. This skill-building feature will allow you to perform “Prevaricator” with confidence, the first time you try it. 

With a running time of 112 minutes and an ebook (included on the DVD) tipping 100 pages (with contributions from Barrie Richardson, Gregory Wilson, Banachek, Ben Blau, Garrett Thomas, Paul Vigil and more), this is a package and a principle of enormous value.
