Let's see, at this time, two 5 star reviews for this trick and neither is a verified purchaser.
Makes you wonder!
What? You guys buy the trick somewhere else and troll PM's site to post your great review and I'm supposed to believe that you're objective.
Or, maybe just some shill for the author?
Regardless, for those of you that think this is "the trick", check out Inferno by Joshua Jay.
Basically, you use the same equivoque to get to the final card, but the finish is much more "dramatic".
And, Inferno is ~$20.00 less expensive.
Just saying...
